FIELD: polymer materials.
SUBSTANCE: invention relates to manufacture of simulated leather-type material with polymer coating, which can be used in making automotive tents, shelters, and for bundling of various technical tools. According to first option, material comprises textile backing and polymer coating formed on said backing with the aid of calender technique at the face and at the underside. Coating is composed of, weight parts: suspension polyvinylchloride (S-7058M) 100, di-2-ethylhexyl phthalate 20-60, di-2-ethylhexyl sebacate 5.0-20, trichloroethyl phosphate 5.0-15, "Vigostab BTs-42" 1.0-3.0, antimony trioxide 5.0-20, aluminum hydroxide 20-5.0, butadiene-nitrile rubber (BNKS-28) 30-0.1, thermoplastic polyurethane (VITUR 2213, 2513) 0.1-70, calcium stearate 0.5-2.0, and pigments 2.0-6.0, weight ratio of layers in material being as follows: face polymer coating/underside polymer coating = (0.3÷0.5):(0.2÷0.4). According to second option, material comprises textile backing and polymer coating formed on said backing at the face and at the underside, face-side polymer coating being formed with the aid of calender technique and composed of, wt parts: suspension polyvinylchloride (S-7058M) 100, di-2-ethylhexyl phthalate 20-60, di-2-ethylhexyl sebacate 5.0-20, trichloroethyl phosphate 5.0-15, "Vigostab BTs-42" 1.0-3.0, antimony trioxide 5.0-20, aluminum hydroxide 20-5.0, butadiene-nitrile rubber (BNKS-28) 30-0.1, thermoplastic polyurethane (VITUR 2213, 2513) 0.1-70, calcium stearate 0.5-2.0, and pigments 2.0-6.0, and underside coating being formed with the aid of deposition technique and composed of, wt parts: emulsion polyvinylchloride (EP-6602Ts) 100, di-2-ethylhexyl phthalate 20-60, di-2-ethylhexyl sebacate 5.0-20, trichloroethyl phosphate 5.0-15, "Vigostab BTs-42" 1.0-3.0, antimony trioxide 5.0-20, aluminum hydroxide 20-5.0, and pigments 2.0-6.0, weight ratio of layers in material being as follows: face polymer coating/underside polymer coating = (0.3÷0.5):(0.15÷0.3). According to second option, material represents film having the same composition as coating in the first option formed with the aid of calender technique, thickness of this film material ranging from 0.15 to 1.0 mm.
EFFECT: enhanced frost resistance, increased level of resistance to multiple bending (also at negative temperatures), and increased level of resistance to abrasion ensuring long service time.
