High-temperature resistant oil-resistant rubber hose

Abstract

The invention relates to a high-temperature resistant oil-resistant rubber hose. The high-temperature resistant oil-resistant rubber hose comprises following ingredients, 100 parts of ethylene propylene diene monomer, 4 parts of a plasticizing softener, 6 parts of cyclohexylthiophthalimide, 9 parts of methyl vinyl silicone rubber, 12 parts of butadiene-acrylonitrile rubber, 1 part of calcium carbonate, 2 parts of diethylene glycol, 3 parts of carbon black, 2 parts of ethlenethiourea, 6 parts of a plasticizing softener, 4 parts of white oil, 3 parts of an anticracking additive, 2 parts of fiber, and 4 parts of a plasticizing softener. The high-temperature resistant oil-resistant rubber hose possesses excellent high-temperature resistance and oil resistance; and is capable of maintaining excellent elasticity, is impervious, and will not become soft at high temperature and under conditions with the presence of fuels containing a plurality of additives; carbon black with excellent insulating properties is added, and the high-temperature resistant oil-resistant rubber hose possesses relatively high insulativity because of excellent non-conductivity and insulation performance of carbon black; and production cost is reduced to a certain degree.

Description

technical field [0001] The invention relates to a rubber product, in particular to a high temperature and oil resistant rubber hose. Background technique [0002] Oil-resistant rubber hose generally refers to the rubber hose connected to the engine for oil transmission. The rubber used for the pipe bushing is usually natural rubber containing tread rubber. Although the above-mentioned rubber has wear resistance, its oil resistance is very poor. Oil resistance can only reach more than 15%. There are also many types of oil-resistant rubber on the market, the main varieties are nitrile, hydrogenated nitrile, and fluorosilicone rubber. Among them, nitrile rubber, hydrogenated nitrile rubber, etc. have good oil resistance, but cannot withstand high temperature; meanwhile, the cost of hydrogenated nitrile and fluorosilicone is very high. The current silicone rubber is kneaded by methyl vinyl raw rubber, white carbon black, hydroxyl silicone oil, hydrogen-containing silicone oil ...

Problems solved by technology

Among them, nitrile rubber, hydrogenated nitrile rubber, etc. have good oil resistance, but cannot withstand high temperature; at the same time, the cost of hydrogenated nitrile and fluorosilicone is very high

The current silicone rubber is made of methyl vinyl raw rubber, white carbon black, hydroxyl silicone oil, hydrogen-containing silicone oil and zinc stearate kneaded by a kneader at high temperature, but the resulting silicone rubber has poor oil resistance.
