(57) Abstract:

The invention relates to light industry, in particular the production of multi-layer material such as artificial leather, which can be used as consumer goods. An object of the invention is to improve the quality of the multilayer material by increasing its light fastness, improve the legibility of the printed picture film coating material and remove its stickiness. This object is achieved in that the multilayer non-woven material includes a base and a polymeric coating having at least one layer consisting of a composition of the following composition, wt. hours : polyvinyl chloride 100, a mixture of plasticizers 40-54, a mixture of fillers 30-40, chloroparaffin CP-470 6-9, calcium stearate 1.5 and 1.7, stearic acid 0,45-0,55, titanium dioxide 8-12, the mixture contains plasticizers di(2-ethylhexyl)-phthalate and plasticizing additive PL-102 in the ratio of 1:0.8 to 1.0, and the mixture of fillers includes chalk and powder cellulose in the ratio of 9 to 19:1 when the ratio of the segments of the base and cover by weight of 1:4-8. table 1.

The invention relates to light industry, in particular the production of a multilayer Mat is S="ptx2">

The closest technical solution according to the essential features and the achieved result is a method of obtaining a layered material, patent RU 239662 C1, class D 06 N 3/06, published. 20.07.1995,

On the basis of fabric coated PVC compositions. 100 m H. PVC:

Di-2-ethylhexylphthalate - 40-60

The disadvantage of the above technical solution is:

- low resistance multilayer polymer coating material;

- stickiness multilayer material on the front surface, the film coating during operation when folding or folds;

- not enough high definition graphics printing, especially small, consisting of blurring their outlines, which reduces the aesthetic perception of this material.

The technical result of the invention is to improve the quality of the multilayer material by increasing its light fastness, improve the legibility of the printed picture film coating material and remove its stickiness.

Postalia least one layer, consisting of a composition of the following composition, wt.h.:

Polyvinyl chloride - 100

A mixture of plasticizers - 40-54

The mixture of fillers - 30-40

Chloroparaffin CP-470 - 6-9

Calcium stearate - 1,5-1,7

the mixture contains plasticizers di(2-ethylhexyl)-phthalate and plasticizing additive PL-102 in the ratio of 1 : 0.8 to 1.0, and the mixture of fillers includes chalk and powder cellulose in the ratio of 9 to 19 : 1 when the ratio of the segments of the base and cover by weight of 1 : 4-8.

The use of the proposed technical solution, a mixture of fillers, including chalk and powder cellulose in the claimed range correlations in polymer compositions, applied to the nonwoven basis, subject to all of the declared essential features leads to the achievement of an unexpected effect, namely:

- selected combination of fillers leads to a high uniformity of their distribution in the preparation of polymeric compositions, i.e., high manufacturability until the drawing on the canvas. When this powder cellulose in this technical solution shows the properties of the dispersive component for homogenization and alignment (intsy can be seen in the mass of a thin layer of a polymeric composition, resulting conditions are uniform, continuous (no breaks) distribution layer of the composition on a non-woven base that provides the best effect of applying a printed pattern on the polymer coating and preserving the clarity of the outline of the picture printing in time,

- in the polymeric matrix coating of this material at the stated combinations of fillers are created optimal conditions for blocking particles of polyvinyl chloride. This effect increases with the content of the fillers to the top of the declared values for all the specified set of features that also affects the expression definition-printed polymer coatings;

due to the block (encapsulation) of particles of polyvinyl chloride reduced autogate main polymer film coating material, the polymer composition is a highly dispersed mixture of different morphology, the nature and particle size distribution of the fillers in the environment plasticized PVC matrix, while ensuring optimal packing of particles of mineral and organic fillers, resulting in improved characteristics of the coating material: eliminated Teva the ratios give the surface a film of a material of high organoleptic properties, original appearance, as well as warm and dry to the touch.

In addition, it should be noted that the use of the proposed technical solution, a mixture of plasticizers containing di(2-ethylhexyl)-phthalate and plasticizing additive PL-102 in the claimed range correlations in polymer compositions, applied to the nonwoven basis, subject to all of the declared essential features leads to the achievement of an unexpected effect, namely:

when mashing dry ingredients in a mixture of plasticizers rapid homogenization of the resulting paste and stable fluidity, while plasticizing additive PL-102 enables the creation of buffer systems of plasticization on the one hand to the PVC matrix, and for a mixture of fillers, in which powdered cellulose, due to the peculiarities of the morphology of the particles: porosity, friability, anisometry, contributes to high integration servings ingredients in weight of the polymeric composition.
