Describes the method of obtaining anti-adhesive agent, including surface treatment of talc functionalized siloxane, a silane, a simple polyester or polymer-based carbon, the composition comprising talc and a component for surface treatment, and the polyolefin containing the above composition. The technical result is the use of anti-adhesive agent for the production of plastic films in a wide range. 3 C. and 10 C.p. f-crystals, 11 PL.

The present invention relates to a product, method for its production and to its use in the production of plastic film. More specifically, the present invention relates to anti-adhesive talc, method of its production and to its use as an additive in the production of polyolefin films.

Polyolefin film obtained according to the method of the present invention are suitable for use in a wide range of applications in the packaging and film coatings.

Background of the invention the Polyolefin film are widely used in packaging and film coatings. The use of polyolefin films continues to grow as the market is e film properties provide the possibilities are almost endless sales growth of products in the future. However, when using plastic film has an initial disadvantage, which may slow their adoption and diffusion in the market, they stick together. When the plastic film is being produced or used in various fields, for which the contact layers of the film there is a tendency to stick together, or "bonding," or "adhesion", which complicates the separation film, opening bags made from a film, or finding the end of the film on rolls with plastic. The present invention relates to compositions based on polyolefin resins, which are specially created so that they have satisfactory anti-adhesive properties.

Anti-adhesive agents are materials that are added to polyolefin resins to impart roughness of their surface and, thereby, to prevent adhesion of the layers of plastic film, and therefore such material is used, the term "anti-adhesive agent. Although it is known that such inorganic materials, such as diatomaceous earth, synthetic silica and talc, reduce adhesion when they are added to the compositions on the basis of polyolefin resins, each of them has both advantages and significant disadvantages.

For example, Antioch what I conversion film, while technological additives are used to improve the film quality and to provide lubrication during extrusion of the film, eliminating the gap extrusion flow. Gap extrusion flow is a measure of the uniformity of the film surface, appearance and strength. Of the three types of additives discussed here, technological additives are subjected to the greatest degree of negative impact due to the presence of anti-adhesive agents. Although it is well known that all anti-adhesive agents absorb technological additives, anti-adhesive agents on the basis of talc absorb a greater amount of technological additives than anti-adhesive agents, either through diatomaceous earth, or on the basis of synthetic silica. Therefore, when the resin composition is obtained in presence of additives, which include anti-adhesive agent on the basis of talc is necessary to increase the dosage of additives. This increase doses adversely affects the overall performance plastic films.

Therefore, you must obtain a new generation of anti-adhesive agents on the basis of talc, which absorb less additives than any synth is about the production of talc, consisting of particles having a layered structure, with each particle has an internal crystalline structure and at least one hydrophilic surface. The method includes heating the particles of talc powder to a temperature below 900oC under such conditions to prevent the transformation of talc in enstatite and in order to carry out the surface modification by substitution inert siloxane groups active silanolate.

U.S. patent 5229094 describes the talcum powder consisting of particles having a layered structure, with each particle contains an internal hydrophobic layers having a crystal structure of talc on the inside of each link and United together by forces of cohesion typical of talc (forces van der Waals forces), talc characterized by the fact that each particle has at least one hydrophilic surface layer.
