A method of obtaining the vibration, sound, acoustic, thermal insulation material used in the automotive, shipbuilding, aviation and other industries (EN 2032700), in which the mixed powder slurry or bulk polyvinyl chloride with the addition of polar compounds, molded under pressure at a temperature up to a certain density, heat in a confined space, and then heated in a free state at a temperature of 190-300oC.

Method for 3-15 minutes provides for producing foamed polyvinyl chloride.

Also known is a method of obtaining elastic penopoluisooli with a closed cellular structure, for use in aircraft construction, shipbuilding, automotive and life as a cushioning and insulating material (SU 1643570).

This material also receive way aemy the material is not flexible enough, and its surface is not protected by a facing layer, which prevented the material from rapid destruction.

Known polymer composition and method for the production of artificial leather-based suspension polyvinylchloride (SU 1643571). The known method provides for mixing of the suspension polyvinyl chloride, plasticizer, stabilizer, filler and ground flax or wool fiber waste and subsequent processing in the extruder and forming a film on the calender, with subsequent embossing and cooling.

However, the composition thus obtained, applicable to the manufacture of artificial skin used in the haberdashery industry.

The closest technology offer artificial leather is a method for the production of artificial leather, in which the base is combined with a polymer film on the basis of suspension polyvinyl chloride when exposed to temperature and pressure with further embossed (EN 2051934).

Technological parameters of production above the skin are as follows: the temperature of the calender rolls is 150-155oWith Generowania camera (temperature gelation) - 140oWith the foaming Temperature - 212-213oWith the Rate this skin cannot be used as teplozvukoizoljatsionnogo material.

Technical problem on which this invention is directed, is to make artificial skin teploizoljatsionnyh properties and the provision of high consumer properties.

The technical problem is solved due to the fact that in the method of manufacturing artificial leather, used as teplozvukoizoljatsionnogo material, by combining the polymer film based on suspension of polyvinyl chloride with a base when exposed to temperature and pressure with a subsequent embossing and cooling according to the invention on a film of suspension polyvinyl chloride composition, wt.h.: Polyvinyl chloride suspension - 100 dioctylphthalate - 45-55 Stearic acid - 0,3-0,8

A method of manufacturing artificial leather, used as teplozvukoizoljatsionnogo material, is as follows.

First prepare a mixture of an adhesive layer, mixing the following components, wt.h.: polyvinyl chloride emulsion 100, the product from a mixture of dioxane alcohols 60-70, which is a plasticizer ADOS, dioctylphthalate 22-30, calcium stearate 1.0 to 2.0. Plasticizer ADOS is a mixture of dioxane alcohols and their high-boiling esters, seasoned stabilizer (BHT, product 2246 and others). THE 2493-003-13004749-93, S. 2 (transparent, nerastraivaisya oily liquid from yellow to dark brown color).

A mixture of dioxane alcohols (ADOS) used in this composition, is a group under the trade name "oxanol, fatty alcohol ethoxylates, which includes the preparation of OS-2 (grades a and B), and sintana DC-10.

Depending on the composition of raw materials as hydroxyethyl groups "oxanol" can be liquid, MAZ, pasty or solid (Chemical encyclopedia, scientific publishing house "Great Russian encyclopedia", M, 1992 , volume 3, page 718).

However, the plasticizer ADOS has a higher adhesive properties compared with the above plasticizer is esitle MINIMUM-13 at a temperature of 30-35oC.

The resulting mixture is applied on the finished film based on suspension of polyvinyl chloride and serves on the conveyor to a hot dryer, the temperature of 120-140oC.

Example.

First prepare a mixture of an adhesive layer, mixing the following components, wt.h.: polyvinyl chloride emulsion 100, plasticizer ADOS, the product from a mixture of dioxane alcohols 60-70, dioctylphthalate 22-30, calcium stearate 1.0 to 2.0.

Plasticizer ADOS is a mixture of dioxane alcohols and their high-boiling esters, seasoned stabilizer (BHT, product 2246 and others ). THE 2493-003-13 004749-93, S. 2 (transparent, nerastraivaisya oily liquid from yellow to dark brown color).

This plasticizer is used for plasticization of vinyl, epoxy, polyester, phenol-formaldehyde and other resins for the production of footwear and sheet PVC, artificial leather, linoleum, rubber compounds, film and sheet materials, etc.

The mixture is prepared in the mixer MINIMUM-13 at a temperature of 30-35oC.

The resulting mixture (layer weighing 120-150 g/m2) put on the finished film based on suspension of polyvinyl chloride and serves on the conveyor to a hot drum, temperatue artificial and synthetic fibers needle-punched non-woven fabric width 135-140 cm also comes to a hot dryer.

The initial connection of the film with the base is carried out by simultaneous feeding of the substrate and the polymer film coated with an adhesive layer between the conveyor and a hot dryer, the temperature of which is 13010oC.

Initially glued basis with the film then goes on embossing, where they are the final bonding rolls at a pressure of 2-2,5 ATM and a temperature of 100-120oC.

There were prepared samples of faux leather on these technologies in industrial equipment.

Next were testing samples, the results of which are shown in tables 1, 2 and 3.

Tests showed that the derived material meets the requirements of teplozvukoizoljatsionnomu material used in vehicles.

The variation of the density of needle-punched nonwoven fabric can meet the demands of the consumer for the purpose and use of teplozvukoizoljatsionnogo material (i.e., less insulation and higher insulation).

The best insulation material corresponds to the balance of the wool fiber is 50:50, respectively, a decrease leads to a decrease of eploits the traditional material is the use of waste products, what affects the cost of the finished material (cheapness).

Thanks to the deep diffusion adhesive layer in the non-woven fabric provides a high bonding strength of the film base, prevents the delamination material in the process of operation, increase strength properties (tensile strength, elongation at break).

The technical result of the present invention is expressed in enhancing performance, improving consumer properties, depreciation is made of insulating material.
