Inert filler concentrates for use in thermoplastic products

FIELD OF THE INVENTION The invention relates to the use of high-density polyethylene glycols to produce concentrated excipients which are used in thermoplastic products of the olefin type, such as polypropylene, polyethylene and in general: polymers which are used alone or in a mixture based on ethylene monomers containing 2 to 6 carbon atoms, polymerized alone or in a mixture. These high-density isotactic polypropyles are used in the invention as vectors favoring dispersion or re-dispersion of the mineral products used as inert fillers in the polyolefins. The invention also relates to concentrates of fillers or feedstocks, based polyester isotactic polypropylenes with very high fluidity. The invention furthermore relates to the thermoplastic loaded products obtained by the addition of selected polypropylenes according to the invention and the manufactured industrial products based on or containing such thermoplastic products. The invention also relates to thermoplastic filler products obtained by adding selected polypropylenes according to the invention and to the manufactured products of or containing such thermoplastic products. It is known to use liquid copolymers to prepare starting mixtures with fillers with high concentration of filler (s), i.e., to levels of approximately 90% calcium carbonate and / or talc. These copolymers are typically copolymers of ethylene, propylene and sometimes butylene. They are known in the trade network under the name VESTERIATS ™ on the company Soleidas-Neis, or REXTAS ™ by Nymplastam. Some also use stylized polypropylenes, by-products derived from the production of isotactic polypropylenes, in particular polypropylene Alphamins 8TN-1 of the company Alkarpat. Also known is the product disclosed in WO95 / 17441, which consists of amorphous polypropylene. 3 The cured polymers of the state of the art are specialized products, that is to say, made in small quantities by specific methods and therefore unprofitable, and which, among other things, lack of hardness and adhesion properties (desirable in the Kopectile liquid adhesives industry) are unfavorable for the above-mentioned application. In addition, they spoil the ultimate mechanical properties of the extruded or extruded objects, derived from feedstocks containing them. Finally, they have softening points (approximately 130-150 ° C) away from the temperature at which they are used (polypropylene 230 ° C, polyethylene 190 ° C). These temperature differences lead to undesirable effects, such as, for example, the deposition of foams, well known to those skilled in the art of extruding profiles or films. The technical problem posed is twofold: polymers should be selected which could lead to very high charge concentrations in feedstocks re-dispersible in the various polymer matrices used in the manufacture of plastics and which do not degrade the mechanical properties of the end- after re-dilution, even increase. Given that the state of the art of the prior art provides starting mixtures, made with copolymeric ethylene, propylene, and sometimes butylactic or astactic, of the amorphous polypropylenes, the invention provides the use of isotactic polypropylenes, i. e. crystalline, with very high fluidity, for the preparation of excipient concentrates which can be used in thermoplastics of the olefin type. It is now known to use polymers having a crystallinity greater than 50%, of polypropylene or other, for a single blend of feedstocks which can reach 80%, but these products are very limited in fluidity with an index Fluidity also called MP (Mellellen), less than approximately 200 g / 10 min (190 ° C - 10 kD - 1.05 mm), according to the modified NPT T 51-620 standard. According to the NP 51-1620 standard, the index of the fluids, also referred to as MP in the remainder of the application, is the amount of polymer and / or copolymer expressed in grams for 10 minutes which expire at a temperature selected within the range of the softening and transformation temperatures of a given normalized filler (2.16 kg, 5 kg , 10 kD, 21.6 kD) in a thread with a defined diameter (2.09 mm at 2.10 mm) over a measured time interval. In the present invention, the modified standard NPT 51-620 is used for polypropylene, a fiber having a diameter of 1.05 mm and a temperature of 190 ° C. Existing devices are adapted to this type of products. Also known is the product described in EP 0203 017 which provides a significant improvement. The improvement comes from a very distinctly higher fluidity that is higher than MPI with 200 g / 10 min (190 ° C -510 kD - 1.05 mm) the concentration of excipients being estimated to be approximately 80-90% in starting mixtures and a percentage of crystallinity significantly decreased by approximately 10%, i.e., one amorphous product. Also known is the product described in Patent No. WO95 / 17441, already mentioned above, which presents the disadvantage of reaching plastic products which are lacking in strength due to problems caused by the resin used which is sticky and difficult to feed . The present state of the art (EP 0 203 017, WO 95/17441) suggests to those skilled in the art that in order to substantially improve fluidity, which is obligatory for the conventional products, while retaining the characteristic, also basic, of a high concentration of filler i) in the starting mixtures, suitably to reduce the crystallinity. It is also proposed (Patent 1) 5,4455, 344) to prepare granulates comprising: a) from 60 to 80 parts by weight of a mineral filler of an average size comprised between 0.05 and 100 ppm; b) from 5 to 35 parts by weight of a crystalline olefin; 150 and 1000 μm, and 5 to 35 parts by weight of a binder having a melting point lower than at least 10 ° C of the detectable olefin. In order to reach such granulates, the prior art method consists in the preparation of the crystalline polyolefin and / or the mineral components with the aid of the binder, which forms one coating providing the adhesion of the particles therebetween. One such method does not result in the production of a composite paste mixture, i.e., of the same composition as the whole of the mixture at the production temperature, but the preparation of non-coherent agglomerates, with the most common composition next to each other, and with uneven sizes, leading later to a poor dispersion. This is probably the reason why the state of the art sells amorphous products on the market. Such entirely amorphous products are more easily obtained by resorting to co-or terpolymers, which then, as some of the preceding products have, in fact, poor crystallinity, problems of consciousness with the olefins. These resins are more melt-flowable and their granules or agglomerates stick to cold presentation and therefore make their processing and dosing significantly difficult. As will be seen from the description that follows, the invention, contrary to this, succeeds in selecting polymers of the type of isotactic polypropylenes with a high fl uidity and exceeding or equal to MEI of 200 g / 10 min, as measured against the modified standard NF T 51-620 (190 ° C - 10 kD - 1.05 mm), preferably above 500 g / 10 min, measured against the modified standard TL 51-620 (190 ° C - 10 kD - 1.05 by a percentage of crystallinity exceeding about 20%, preferably in the range of 30% to 90%, preferably between 50% and 85%, and resulting in starting mixtures with 7 characteristics that are both remarkable and surprising, i. e. , - has a filler content of 80% or greater, - has a high fluidity, i.e., an MPI exceeding 5 g / 10 min (190 ° C - 5 kD - 2.09 mm) in accordance with the NPS standard T 51-620, preferably exceeding 8 g / 10 min (190 ° C - 5 kD - 2.09 mm), and - contains at least one polymer of the isotactic polypropylene type, representing a percentage of crystallinity , also an isotactic index) more than about 20%, preferably between 30% and 90%, most preferably between 50% and 85%, which is in fact the opposite of the state of the art. This isotactic index is a temperature exceeding 140 ° C, a blowing power of the foil between 40U / d and 138U / g, as described by Kepkakel et al. in the present application, the crystallinity or isotacticity index is defined in the present application by the introduction of a calorimetric differential method called the OZC (O) Auspüd Süüpfeu) with the aid of a device 20 on the Meier-Tolleu, which allows to measure the energy of melting of the polymeric filler and to determine the index by comparing with the value of 138 μg / g, which corresponds to an index of 100%. This method of determining crystallinity or isotactic index will be called DSD in all of the following. Moreover, these feedstocks allow to harden the hardness of the grains, so far difficult to achieve. Other features and advantages of the invention will be better understood from the following description. It is appropriate to specify that throughout the present specification, & quot; isotactic polypropylene & quot; refers to isotactic polypropylenes containing a very low percentage, unavoidable and known to those skilled in the art, a polypolymer or a portion of a contacting polymer. These isotactic polypropylenes with very high fl uidity are, moreover, (EP 0 523 717 or EP 0 600 464). It will be appreciated by those skilled in the art that such polymers subject to degradation in which one participates in a radical reaction must be regarded as equivalenttechniques. They are characterized by their fluidity or MI as measured according to the modified NPT T 51-620 standard that exceeds or is equal to 200 g / 10 min (190 ° C - 10 kD - 1.05 mm) and their percentage of crystallization exceeding approximately 30% measured by the M5Smod. One of the features of the invention is therefore also to use these isotactic polypropylenes obtained by direct polymerization. This represents an important advantage, even decisive, 9 since this technique allows to avoid the products of numbelling or by-products of polymerization which often are the cause of the degradation of the ultimate mechanical properties and the fluctuations of the hardly achievable industry qualities. Another decisive advantage is to allow the specialist in the field to design, with a very high degree of freedom, precisely the product that is needed for the exact application under consideration and / or to take into account the pre-production equipment. The capacity is provided, as will become apparent below, the possibility of retaining the advantages of the invention while at the same time specifying the degree of crystallinity and stiffness. The present invention therefore relates to a method of obtaining feedstocks or mineral concentrate concentrates which are highly mineral-filled, which are used to fill thermoplastic products with the aid of said mineral fillers, by making polymers or mixtures of polymers such as binders characterized by characterized in that said polymers or polymer blends: - contain at least one isotactic polypropylene, and - have a crystallinity percentage, generally referred to as isotactic ratio, exceeding approximately 20%, preferably in the range of 30% to 90%, more preferably between 50% and 85%, as measured by the DSD method as described above . 10 In addition, we will specify for a good understanding of the terms used, the corresponding definitions for isotacticity, for the contact and for the syndiotactic polymers. Thus, the isotacticity characterizes, in the case of the unleaded polymer, the presence of substituents only the counterion side of the carbon backbone of the molecule, while, on the contrary, an aseptic polymer has distributed substitutions on both sides in a random fashion. A syndiotactic polymer represents, from the site, repetitive sequences of substituents on each side. These concepts are well within the skill of the art but can nevertheless, to make a comparison with the Chrysanthemums of the present invention, Figure 25.1, Figure 25.1, and Figure 15.1. Reference may also be made to the general considerations in this area, namely with respect to Tg (glass transition temperature) and Tm (melting point) with the article of Lactoglucose without Nail Roller et al.
