Abstract
The present invention relates to an application of EVM rubber in the preparation of automobile oil return pipes. The EVM rubber is made of the following materials in parts by weight: 40 parts of EVM700HV raw rubber, 60 parts of EVM500HV raw rubber, and 1 to 3 parts of magnesium oxide , 1-3 parts of calcium oxide, 1-2 parts of stearic acid, 50-70 parts of carbon black, 30-50 parts of filler, 8-15 parts of processing oil, 2-6 parts of anti-aging agent, 3-5 parts of tackifying resin parts, 5-8 parts of peroxide vulcanizing agent, and 3-4 parts of vulcanization aid; the present invention also provides the application of the above-mentioned EVM compound. The advantage of the present invention is that: the EVM rubber compound of the present invention adopts EVM700HV rubber compound and EVM500HV rubber compound together, and with a certain preparation method, the prepared rubber compound has excellent high temperature resistance, oil resistance and ozone resistance.
Description
technical field [0001] The invention relates to a rubber material for an oil return pipe, in particular to the application of an EVM rubber material in preparing an oil return pipe for an automobile. Background technique [0002] EVM is a polymer material formed by the copolymerization of ethylene and vinyl acetate, referred to as ethylene-vinyl acetate copolymer, also known as Yihuaping, after proper mixing of EVM vulcanizate, because of its excellent aging resistance It is known for its high resistance (maximum service temperature of 175°C), excellent weathering and ozone resistance, UV stability, low compression set and good processability. EVM is now found in many rubber products including cables, adhesives, and for the modification of thermoplastic elastomers. Due to more stringent high temperature requirements, it is increasingly used as seals and gaskets in the automotive industry, but it is less used for automotive oil return hoses that are both oil resistant and hi...
