Heat-resistant polymer composite material based on siloxane rubber and method for production thereof

FIELD: chemistry. SUBSTANCE: invention relates to heat-resistant composite materials, which can be used in various industries, in particular in aircraft and space equipment, and to a method for preparing them. Described is a heat-resistant polymer composite material, containing siloxane rubber as a matrix and multi-wall carbon nanotubes (CNT) as filler in amount of 0.1–1.0 wt% per 100 g of pts.wt matrix, wherein material has heat resistance: weight change at 400 °C not more than 3.93 %, and physical-mechanical properties: modulus of elasticity in tension 0.93–3.63 MPa at relative elongation of 330–505 %. Also described is a method of producing polymer composite material. EFFECT: technical result is producing a novel polymer composite material with high heat resistance and improved mechanical properties based on siloxane rubber as a matrix and carbon nanotubes as filler. 6 cl, 9 dwg, 1 tbl, 8 ex
