Abstract

The invention discloses a flame retardant and heat resistant rubber material. The flame retardant and heat resistant rubber material is prepared from the raw materials in parts by weight: 40-60 parts of hydrogenated nitrile rubber, 15-20 parts of butyl rubber, 5-15 parts of ABS (Acrylonitrile Butadiene Styrene) rubber, 1.5-2.5 parts of p-benzoquinone, 2-3 parts of lead oxide, 2-3 parts of magnesium oxide, 1.5-2.5 parts of vulcanization accelerator DM, 2-5 parts of trimellitate tri(2-ethylhexyl) trimellitate, 0.8-1.3 parts of epoxy soybean oil, 2.5-4 parts of environmental-friendly flame retardant FR, 1.5-2 parts of antimony trioxide, 25-35 parts of talcum powder, 15-20 parts of attapulgite modified clay and 2-4 parts of novel rubber reinforcing agent. The flame retardant and heat resistant rubber material has excellent elastic property and heat resistance and good ageing resistance, wear resistance and tear resistance.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a flame-retardant and heat-resistant rubber material. Background technique [0002] Hydrogenated nitrile rubber is a highly saturated elastomer obtained by special hydrogenation of nitrile rubber. Hydrogenated nitrile rubber has good oil resistance, and because of its highly saturated structure, it has good heat resistance, excellent chemical corrosion resistance, excellent ozone resistance, and high compression set resistance; at the same time hydrogenated Nitrile rubber also has the characteristics of high strength, high tear performance and excellent wear resistance, and is one of the rubbers with excellent comprehensive performance. Due to the good properties of hydrogenated nitrile butadiene rubber, hydrogenated nitrile butadiene rubber is widely used, but the existing hydrogenated nitrile butadiene rubber is still difficult to meet certain high-temperature use env...
