Abstract

The invention discloses a silicone rubber high temperature-resistant rubber pipe. The silicone rubber high temperature-resistant rubber pipe comprises, by weight, 80-120 parts of modified methyl vinyl silicone rubber, 30-60 parts of an ethylene-propylene-diene monomer, 10-30 parts of tetrafluoroethylene-propylene copolymer rubber, 5-15 parts of a plasticizing softener, 2-8 parts of cyclohexylthiophthalimide, 3-9 parts of nitrile rubber, 4-8 parts of calcium carbonate, 1-5 parts of diglycol, 2-6 parts of carbon black, 4-8 parts of 1, 2-ethylene thiourea, 2-5 parts of white oil, 3-9 parts of a cracking prevention agent, 2-4 parts of fibers, 4-8 parts of dilead tetraoxide, 3-9 parts of dioctyl phthalate and 4-8 parts of Antilux 654. The silicone rubber high temperature-resistant rubber pipe has good high temperature resistance and high toughness and satisfies demands in actual use.

Description

technical field [0001] The invention relates to a rubber hose, in particular to a silicone rubber high temperature resistant rubber hose. Background technique [0002] Hose is a type of tubular rubber product used to transport gas, liquid, slurry or granular materials. It is composed of inner and outer rubber layers and a skeleton layer. The material of the skeleton layer can be cotton fiber, various synthetic fibers, carbon fiber or asbestos, steel wire, etc. Generally, the inner and outer rubber layers of rubber hoses are made of natural rubber, styrene-butadiene rubber or butadiene rubber; oil-resistant hoses are made of neoprene and nitrile rubber; acid-resistant and high-temperature resistant hoses are made of ethylene-propylene rubber, fluorine rubber or silicone rubber. [0003] The high temperature resistant performance of the rubber hose in the prior art is poor and cannot meet the requirements of actual use, so continue to design a high temperature resistant rubbe...
