Multilayer material

 

(57) Abstract:

The invention relates to light industry, in particular the production of multilayer materials for technical purposes. An object of the invention is to improve the quality of the multilayer material by increasing its light fastness, improve the quality of the stamping film coating material - definition picture and improving the technological process of making books from this material by eliminating adhesion binding covers with the finish on tinylinux presses and sticking of the books when laying them in a pile. This object is achieved in that the multilayer material includes a paper base and a polymeric coating having at least one layer consisting of a composition of the following composition, wt.h: polyvinyl chloride 100, a mixture of plasticizers 35-45, a mixture of fillers 22-28, stabilizers: calcium stearate 1,9-2,2, complex barium-cadmium 2.8-3.2, and the pigment of 1.9 to 2.4, the mixture contains plasticizers di(2-ethylhexyl)-phthalate and plasticizing additive PL-102 in the ratio of 4-6:1, 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 sooty multilayer materials for technical applications designed, for example, covers of books, notebooks, albums, etc.

The closest technical solution according to the essential features and the achieved result is artificial leather, made when applied to the nonwoven base PVC composition comprising PVC dispersion polymer, plasticizers, thickeners, fillers, foaming agents, stabilizers and pigments, patent GB 1113272 And class. D 06 N 3/04, publ. 08.05.1968,

Known technical solution does not provide a high light-fastness of polymeric coating material, there

- deterioration in the clarity of the embossment of the polymer film during operation of the material, leading to deterioration of the product;

- adhesion binding covers made of this multi-layered material, when you finish printing foils and inks to detail finishing tinylinux presses and printing machines, which leads to forced shutdowns of the equipment and the formation of defective products;

- sticking bound book blocks, made with the use of this material, in the process of crimping, stacking and pressing manifested on the surface of the ILSA film material surface with the formation of large defects, worsening marketable books.

The technical result of the invention is to improve the quality of the multilayer material by increasing its light fastness, improve the quality of the stamping film coating material - definition picture and improving the technological process of making books from this material by eliminating adhesion binding covers with the finish on tinylinux presses and sticking of the books when laying them in a pile.

This objective is achieved in that the multilayer material includes a paper base and a polymer coating at least one layer consisting of a composition of the following composition, wt.h.:

Polyvinyl chloride - 100

A mixture of plasticizers - 35-45

The mixture of fillers - 22-28

stabilizers:

Calcium stearate - 1,9-2,2

Complex barium-cadmium - 2,8-3,2

The pigment is 1.9 - 2.4

due to the block (encapsulation) of particles of polyvinyl chloride reduced autogate main polymer film coating material, resulting in preventing the adhesion binding covers made from this material, to create the best slide books;

polymer composition predstaviteley environment plasticized PVC matrix, this provides optimum packing of the particles of mineral and organic fillers, resulting in improved characteristics of the coating material: eliminates stickiness and improves the lightfastness;

- selected combination of plasticizers and fillers in the stated proportions 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, plotted on a paper 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, for the PVC matrix, and for a mixture of fillers, in which powdered cellulose, thanks sediento in weight of the polymeric composition.

Violation of composition and ratios of components in the multilayer material leads to disruption of its structure and, consequently, to the loss of physical and mechanical properties of the material and the possibility of further use of it.

In the proposed technical solution used the following components:
