FIELD: chemistry.
SUBSTANCE: invention relates to polymer processing, particularly production of synthetic leather which can be used for pool finishing. The bioresistant waterproofing polymer material includes a polyester base and a polyvinyl chloride coating. The base is made of cross-weave polyester threads with mesh size of 2x2 mm, wherein the weight ratio of the layers - front:intermediate:back is 9:1:9, respectively, and the weight ratio of the layers - polyester base:polymer coating is 1:18. The polyvinyl chloride coating is obtained from suspended polyvinyl chloride and additionally contains a mixture of plasticisers - dioctyl phthalate, dioctyl adipate, diglycidyl ester of 1,4-butanediol laproxide BD with weight ratio of epoxy groups of 24-34% and synthetic butadiene-nitrile rubber with weight ratio of acrylonitrile of 26-30% in ratio of 1:0.8:0.2:0.6, respectively; the stabiliser used is Baerostab UBZ 711-1x RF; the bactericidal additive is Bioneutral M 10; the composition is coloured using pigments.
EFFECT: invention provides resistance to wearing loads and atmospheric phenomena, the effect of microorganisms and formation of algae, temperature drops, as well as shearing strength of a welded joint.
