Abstract

The invention relates to KOhoizaciu for the manufacture of bottom shoe parts. The invention makes it possible to increase the adhesion coefficient of the material with ice at up to 0.49, reduce the melt viscosity to a melt index of 8 g / 10 min and impart transparency to the material. This is achieved by introducing a mol-m-butadiene-styrene copolymer into the composition. (80–200) S with a bound styrene content of 75–85%, 80–100% of which is in the macromolecule in the form of 1–3 polystyrene blocks, and the composition contains, in different parts: styrene-butadiene block copolymer (with a bound content of ZOX styrene) 100, said copolymer 20-60, mineral filler 1-30, plasticizer. 1-30, dye 0.1-5.0 and an + ioxidant 0.1-3.0. 1 hp ff, 2 tab. § (ABOUT

Description

h

with co

The invention relates to light industry and can be used in the shoe industry to make molded soles. The purpose of the invention is to reduce the viscosity of the melt of the composition, to increase the coefficient of adhesion of the material to ice while giving the material transparency.

The composition is prepared by mixing the components on a mixing roll with a roll temperature of 30 minutes.

As a styrene-butadiene block copolymer, a copolymer with a bound styrene content of 30% of type DST-30 is used.

The styrene-butadiene copolymer used is a CCA-85 copolymer with a molar mass of (80-200) -10, a bound styrene content of 75-85%, 80-100% of which is in the form of 1-3 polystyrene blocks.

Molded products by injection molding or pressing at 160 ° C. Measurement of physico-mechanical parameters is carried out in accordance with GOST, the melt index is determined at a pressure of 49.1 ° C and a temperature of 190 ° C, material transparency is visually, the coefficient of material adhesion with ice is according to GOST,

Table 1 shows the formulations of the compositions; Table 2 shows the material properties for the bottom of the shoe; Table 3 characterizes the styrene-butadiene copolymer.
