Abstract

The invention discloses a heat-resisting rubber composite material and relates to the technical field of high molecular materials. The composite material is prepared from, by weight, 86-97 parts of EPDM rubber, 15-25 parts of 1,3-butadiene, 5-10 parts of poly butyl acrylate, 8-15 parts of zinc oxide, 3-7 parts of magnesium oxide, 1-3 parts of stearic acid, 1-3 parts of an anti-aging agent, 30-35 parts of plasticizer, 3-7 parts of dicumyl peroxide, 50-65 parts of carbon black, 2-5 parts of hollow glass beads and 0.5-2 parts of sulfur. The EPDM rubber is adopted as matrix rubber and mixed with other auxiliary materials, and therefore heat resistance of the matrix rubber is given into full play; abrasive resistance of the composite material is further improved, hardness is high, stretching resistance and tear resistance are high, heat and cold resistance is good, adaptability to the environment is high, the application range is wide, in the process of preparing the composite material, by strictly controlling technological parameters such as vulcanizing temperature and vulcanizing time, the obtained composite material is good in quality and long in service life, the preparing technology is simple, and large-scale production can be achieved.
