The indication of an invention

Object of the Invention

[0005] However, when mixing an ultraviolet ray absorbent into a base, an ultraviolet ray absorbent may decompose by operation of the ingredient in a base, and it may not demonstrate sufficient ultraviolet absorption effect.

[0006] When giving a photocatalyst function to the base surface, there is a possibility that the base itself may carry out decomposition degradation by photocatalyst operation depending on the kind of base. Basis which has a photocatalyst function Problem which adsorbs electrostatically the contaminant which has positive charge since the body is tinged with the minus electric charge Power^sIt is.

[0007] The present invention sets it as the purpose to provide the new technique of preventing thru/or reducing adhesion of a contaminant at the same time it prevents thru/or reduces temporal fading thru/or discoloration of a base. Means for solving problem

[0008] The objects of the present invention are a positive charge substance and a minus electric charge substance on the base surface or in a base surface coat. It is attained by arranging. A positive charge substance has (1) positive-ion; (2) positive charge. It is a substance which has one sort chosen from the group of the electric conduction object which has an electric conduction object or dielectric;, and (3) positive charge and a dielectric, or a semiconductor, which consists of complexes, or two sorts or more of positive charge. Things are preferred. The electric conduction object in which a minus electric charge substance has a (4) negative-ion; (5) minus electric charge, or dielectricity Electric conduction object which has a body; (6) minus electric charge, and complex; of a dielectric or semiconductor , and (7) lights one sort chosen from the group which consists of a substance which has a catalyst function, or two sorts or more of minus electric charges -- an owner -- It is preferred that it is a substance to carry out. The electrification pressure on the above-mentioned surface of a base is 50V to 50V. It is preferred that it is within the limits.

[0009] As for the above-mentioned base, it is preferred that they are hydrophilicity, hydrophobicity, water repellence, or oil repellency.

[0010] the above-mentioned positive charge substance and a minus electric charge substance form an intermediary layer together -- good -- better -- Scum it is -- a case -- between the layers of the above-mentioned base surface, the above-mentioned positive charge substance, and a minus electric charge substance -- the middle class It may form. An enveloping layer is provided on the layer of the above-mentioned positive charge substance and a minus electric charge substance. It is good. Arbitrary [ to a base ] by choosing the material property of the above-mentioned middle class and the above-mentioned enveloping layer A surface property can be given.

EFFECT OF THE INVENTION

[0011] The contaminant adhering to the contaminant and/or base which are floating in the atmosphere is sunlight etc. Although it is photooxidized by operation and is tinged with positive charge, the surface of the base in which the method of the present invention was given repelling the above-mentioned contaminant electrostatically, since positive charge exists -- from the base surface -- self--- It breaks away with Natural. Therefore, it becomes possible to carry out self cleaning of the base surface.

[0012] Since a minus electric charge exists in the surface of the base in which the method of the present invention was given, the pollution invitation substance which has a minus electric charge like the chloride ion in Carrion clay fine powder and tap water, and electrostatic are opposed, and adhesion on the base surface is barred. Therefore, such impurities It is good to prevent change of the base surface property by adhesion, and to maintain the base surface purely. It becomes ability.

[0013] On the other hand, they are vegetable cells, such as microorganisms, such as mold, pollen, and a seaweed, Positive and electric charge of negative both sexes The contaminant which has the positive charge which many were tinged and was mentioned above is also on the higher rank of an electrification sequence. By carrying out frictional contact to a substance, some positive charge is reversed to a minus electric charge, and they are positive charge and a minus electric charge. It may have both unique electric charge characteristics. Friction with the substance of others [ pieces / of textiles /, such as cotton and silk, ] Positive and negative unique electric charge characteristics convertible by Rubbing are shown.

[0014] Since positive charge and a minus electric charge exist in the surface of the base in which the method of the present invention was given, even if it is substances, such as a contaminant which has the unique electric charge characteristics of both positive charge and a minus electric charge, pollen, an alga, mold, and a piece of textiles, it becomes possible to reduce adhesion in these bases.

[0015] However, when either the amount of positive charge or the amount of minus electric charges is superfluously large, the tendency to adsorb the contaminant which is tinged with positive charge by the impurities or photooxidation which has a minus electric charge becomes strong, and it is a base as a result. Since there is a possibility that the surface may be polluted, the base surface -- seemingly -- the amount of positive charge, and Negative electricity the state where the amount of loads is balanced -- good -- better -- Tooth -- specifically, it is preferred that the electrification pressure on the surface of a base is within the limits of 50V to 50V.

[0016] When the above-mentioned base, the above-mentioned middle class, and/or the above-mentioned enveloping layer are hydrophilicity, hydrophobicity, water repellence, or oil repellency, use these character, and also they are Across and a base to a long period of time. Adhesion of the contaminant to the surface can be prevented thru/or reduced.

[0017] Furthermore, the base processed by the method of the present invention has high resistance to the operation itself, such as sunlight, and can protect a base from optical degradation by sunlight etc. satisfactorily. From book The base processed by the method of Ming is quantity also to contamination not only the inside of the air but underwater. It is and resistance is shown.

[0018] reducing [ the present invention / at a long period of time / Across-prevent, thru/or ]-by operation of these,-fading thru/or discoloration of base power S -- last .

[0019] Water can be sanctified by the base in which the method of the present invention was given stabilizing heavy metal ion, such as an underwater mineral ingredient, a chlorine compound, for example, trihalomethane, and cadmium, and suppressing generating of fungi or a seaweed.

[0105] next, the mechanism in which a contaminant is removed from the base surface which is tinged with positive charge -- a figure -- it is shown in 5. Although the layer containing a positive charge substance and a minus electric charge substance is arranged as a monolayer for convenience, they are two or more layers. It may be.

[0106] first -- a figure -- as shown in 5, give positive charge and a minus electric charge to the base surface (figure 5 (1)).

[0107] A contaminant accumulates on the base surface and it is photooxidized by the operation of electromagnetic waves, such as sunlight. In this way, positive charge is also given to a contaminant (figure 5 (2)).

[0108] Electrostatic rebounding of positive charge occurs between the base surface and a contaminant, and rebounding secession power is Stain. It generates in the quality of dyed goods. Thereby, the adherence power of the contaminant on the surface of a base is reduced (figure 5).

[0109] A contaminant is easily removed from a base by the physical operation of a rainstorm etc. (figure 5 (4)).

Thereby, self cleaning of the base is carried out.

[0110] The contaminant or pollution invitation substance which, in addition, has minus electric charges, such as Carrion clay fine powder and chloride ion, since a minus electric charge also exists in the base surface is also repelled similarly, and it is a base table. The adherence power to a field is reduced.

[0111] it comes especially out of the base which is the target of the present invention to use the hydrophilicity or the hydrophobic inorganic system base of the various kinds which drop off in what is limited and organic system bases, or those combination It cuts.

[0112] that for example, soda lime glass etc. are transparent as an inorganic system base or devitrified glass, and Jill Substances, such as metal oxides, such as Conia, ceramics, concrete, mortar, a stone, and metal , -- a base is mentioned.

[0113] Especially the shape of a base can take arbitrary shape, such as a cube dropping off, a rectangular parallelepiped, a globular form, a sheet form, and a fiber type, in what is limited. A base may be porous. Base The surface may be hydrophilicity-ized by corona discharge treatment or ultraviolet exposure processing. As a base, they are the substrate for construction' engineering works or sealing material Well,, apparatus, a body for device conveyance, and a table. Display surface is preferred.

[0114] The surface of a base is as Well paint material, even if painted, Alkyd resin, an acrylic resin, Amino resin, polyurethane resin, an epoxy resin, Silicone resin, a fluoro-resin, acrylics A synthetic resin and colorant, such as silicon resin, unsaturated polyester resin, ultraviolet curing resin, phenol resin, vinyl chloride resin, and Containing resin, are contained! Understand pen A paint can be used conveniently.

[0115] the thickness of the above-mentioned paint film -- 0 and 01*; 100 m power S -- desirable -- 0- ; !. * 50 m -- more -- good -- better -- Tooth 0 and 5 m* 10 m are preferred especially. As application means, the Sprayco 1 Tyng method, the dip-coating method, a flow coating method, a spin coating method, a roll coating method, brush coating, sponge coating, etc. are applicable, for example. In order to raise physical performances, such as hardness of a paint film, and adhesion nature with a base, it is a permission example of a base and a paint film. Heating in an enclosure is desirable.

[0116] power in which protecting the base surface by covering the base surface with the organicity or the inorganic matter which has outstanding water-repellent and oil repellency, or hydrophilic and hydrophobicity conventionally was also performed the organicity concerned -- moreover -- Since the inorganic matter generally has a minus electric charge, a contaminant adheres temporally. the -- There was a problem that the protection characteristic lost remarkably. It carries out and power is also such in Naka et al. and the present invention. Since positive charge and a minus electric charge are given to the base surface, there is no such problem. Base Since surface chemical property is not spoiled, it is the characteristic of the organicity concerned or an inorganic matter. The self cleaning characteristic can be given, maintaining. [0117] That is, use the positive charge and the minus electric charge which are given to the base surface in the present invention, and it is a basis. Raw power and the product carried out are good in continuous "antifouling and an antifog function" at the same time it employs the functionality of the body itself efficiently. It becomes ability. The power in which this art is applicable to all bases, especially outstanding water repellence and hydrophilicity It is that function in the long run by giving positive charge and a minus electric charge to the surface of the organic substance which it has. Since it is maintainable, the application to the base made from a plastic is preferred. Thereby, "Tic [ Lei Plus / become / dirty ]" becomes possible.

[0118] The positive charge on the surface of a base can reduce oxidization degradation of the base by electromagnetic waves. Namely, oxidization degradation of a base is [ be / it / under / base surface or base / setting ] electromagnetism, such as ultraviolet rays. It is a field for radical, such as 'theta and - omicroneta, to be generated by the wave and to produce an oxidization decomposition reaction.
