FIELD: chemistry.SUBSTANCE: invention relates to composite polymer materials based on a butadiene-acrylonitrile elastomer, which are widely used in cable production and footwear industry. The composition contains a butadiene-acrylonitrile elastomer SKN-26, polyvinyl chloride, sulphur, captax, thiuram, stearine and technical carbon. Components are in the following ratio, pts.wt: butadiene-acrylonitrile elastomer SKN-26-80, polyvinyl chloride 20, sulphur 1.8, captax 1, thiuram 0.2, stearine 0.2, technical carbon 0.1-5.37. The polymer composition is modified by technical carbon nanoparticles with average particle size of 20-30 nm, the amount of which is determined using the following formula: c=0.1e, where n=0, 1, 2, 3, 4, e=2.7. The invention can be used in producing vulcanisates with high tensile strength, tear resistance, good dynamic properties and heat-ageing resistance.EFFECT: articles made from the composition are characterised by such vital physical properties as strength, work of adhesion, permittivity, modulus of elasticity, mechanical and dielectric losses.9 dwg, 1 tbl, 6 ex |
