Production of molded article of aerated lightweight concrete

[Detailed Description of the Invention]

The object of an invention (Field of the Invention) The present invention relates to the manufacturing method of the autoclaved-lightweight-concrete (henceforth [ ALC ]) cast in which a pattern, color, etc. were printed on the surface. (PRIOR ART) When giving a pattern and color conventionally to the ALC panel for interiors, as shown in Drawing 5, the method of sticking on ALC panel 11 wallpaper 13 in which waterproofing N15, color layer 16, and topcoat layer 17 were beforehand provided on glass fiber sheet 14 via adhesion Ji12 is known. As for with Blow, as for the above-mentioned color layer 16, the pattern of color is obtained by paint. Since it was formed with Blow by paint, color layer 16 to which (the problem to which it is supposed that an invention will be solved), and color [ in / in time / the conventional describing / above / method ] were given had the restrictions on the design that a design with it is difficult. [ accuracy / in / it does not become smooth and / the outer edge section of color / bad / the surface / and and ] [ free / the surface ] Since it was permeable with the conventional wallpaper, the panel of ALC could not be used but it was unsuitable for the outer wall. It is in the object of the present invention canceling the above-mentioned problem, and providing given fields, such as a pattern and color, with the simple manufacturing method of the ALC cast in which a free design is possible. Constitution of an invention (Means for solving a problem) To achieve the above objects, the present invention provided the ALC fabrication cast top material coat layer, and has adopted the composition of covering the no water permeability sheet by which printing processing was carried out on the adhesion layer. (OPERATION) Signs that printing processing twists in a desired free design beforehand on ALC fabrication cast top material by having adopted the above-mentioned composition, The no water permeability sheet in which color etc. were given is easily joined via the adhesion layer by the acrylic adhesives etc. which are elastic, for example, and the ALC cast made into the object is obtained. (EXAMPLE) Below, it is based on the 1~4th figure, and one example which materialized the present invention is described. As the ALC cast in which the pattern etc. were given to the surface obtained by this example by printing processing is shown in Drawing 1, no water permeability sheet 3 by which printing processing was beforehand carried out via adhesion layer 2 on ALC panel 1 as an ALC cast substrate is joined. The no water permeability sheet 3 consists of glass fiber sheet 4, waterproofing layer 5, printing layer 6, and topcoat layer 7. Next, it acts [ the ] and explains with an effect the manufacturing method of the ALC cast which has such composition. First, as shown in Drawing 2, no water permeability sheet 3 is obtained as follows. After applying the emulsion of silicone series resin on glass fiber sheet 4, waterproofing N5 dried and obtained is provided. As a synthetic resin used in order to form the waterproofing layer 5, water-repellent resin, such as silicone series resin, is used in addition to acrylic resin. Next, printing layer 6 which carried out printing processing of signs that it is based on a desired design, the color, etc. is formed on the waterproofing layer 5. It is more desirable to use a weatherproof inorganic pigment, when using it as an object for outer walls. As for the pattern of natural stones, such as marble and a granite, color, etc., printing processing is improved the printing N6 by accuracy. And topcoat layer 7 is formed by applying the paint consisting of silicone series resin on the printing layer 6. As a paint which forms the topcoat layer 7, the paint consisting of fluororesin and urethane system resin can also be used. The range of 0.05~IIIIll+ is preferred for the thickness of the above-mentioned no water permeability sheet 3. If the fine concavo-convex shape of the ALC panel 1 surface appears easily in the no water permeability sheet 3 surface in less than 0.05 mm and this thickness exceeds IIIIIll, it will become disadvantageous economically, and it becomes difficult to make it follow to ALC panel 1. It will be satisfactory, if it is in a mentioned range, and there are predetermined hardness and elasticity even when no water permeability sheet 3 is thin. As for no water permeability sheet 3, since ALC panel 1 is [ water absorbency ] high, in order that waterproof performance may be given, it is preferred that the water penetration performance specified by JIS-A6910 is a thing of 0.5 ml or less. Since moisture will permeate printing layer 6 of no water permeability sheet 3 easily from ALC panel 1 in using it especially as an object for outer walls if the water penetration performance exceeds 0.5++1, it is not desirable. Next, the glass fiber sheet 4 side of no water permeability sheet 3 produced by doing in this way is stuck to the above-mentioned ALC panel 1 by adhesion N2 by acrylic normal temperature hardening-liquid type adhesives. That is, adhesives are applied all over the surface by the side of glass fiber sheet 4 of no water permeability sheet 3, and it lays on top of the surface of ALC panel 1 in which this is not given to a surface treatment. The end of no water permeability sheet 3 is turned and stuck even on the side of ALC panel 1. Thus, by making an elastic sheet intervene and accumulating two or more sheets up and down so that obtained ALC panel 1 may not be pasted up mutually, it pressurizes and pastes up no water permeability sheet 3 to ALC panel l. Then, adhesives result in the state which it hardens at normal temperature and shows in Drawing 1. As adhesives, they are urethane system adhesives besides the above-mentioned acrylic adhesives, It is desirable since adhesives with the elasticity of rubber adhesive, such as chloroprene rubber and nitrile rubber, silicone series adhesives, etc. follow elasticity by the heat of ALC panel 1, and in order for there to be no wrinkles in the surface of printing layer 6 and to make it finely. Therefore, the adhesives without the elasticity of epoxy adhesive etc. are not preferred. Since the whole surface of the glass fiber sheet 4 side surface of no water permeability sheet 3 pastes up with adhesives using adhesives with such elasticity, the whole pastes up certainly to ALC panel 1, and no water permeability sheet 3 serves as the smooth surface. Thus, the ALC cast in which the desired pattern etc. were drawn on ALC panel 1 is manufactured. Thus, ALC panel 1 which no water permeability sheet 3 in which a pattern by a desired design, etc. were printed pasted up via adhesion layer 2, When used as outer wall material of a building, as shown in Drawings 3 and 4, Notch part 8 is provided in the adjoining part of adjoining ALC panel 1, respectively, and crevice 9 formed of both Notch part 8 is filled up with sealing members 10, such as silicon system rubber and acrylic rubber. Therefore, between adjoining ALC panels 1, since the end of no water permeability sheet 3 on ALC panel 1 is filled with sealing member 10 while waterproofness is fully maintained, it is not necessary to process the end of no water permeability sheet 3 specially. As mentioned above, since enough no water permeability sheets 3 to bury fine unevenness of the ALC panel 1 surface are provided according to the manufacturing method of the ALC cast of this example, the surface is smooth and excellent in appearance. The ALC cast in which a Spy pattern, color, etc. were given to natural stones, such as marble and a granite, by printing is easily obtained only by sticking no water permeability sheet 3 on ALC panel l as it is. Since this no water permeability sheet 3 fully follows elasticity by the heat of ALC panel 1, the appearance which was excellent in the no water permeability sheet 3 above-mentioned surface is held for a long period of time. It is since the coat which has the weatherability which consists of silicone series resin as topcoat layer ? in no water permeability sheet 3 was provided, It can use suitably as an outer wall of a building, and the surface state of ALC panel 1 where signs that it is based on a free design in that case, color, etc. were given is held as it is over a long period of time. The present invention is not limited to the above-mentioned example, and can also be constituted as follows. That is, Tutsbuko i A layer 7 on printing layer 6 provided in no water permeability sheet 3 can also omit the above-mentioned Top knee Fi17 in the indoor use which does not need weatherability. Even if constituted in this way, the object of the present invention can be achieved. EFFECT OF THE INVENTION According to the manufacturing method of the ALC cast of the present invention, the outstanding effect that the ALC cast in which given fields, such as a pattern and color, are smooth and a free design is possible is obtained easily is produced.
