Abstract

The invention discloses a seal rubber for a water pump of an automobile. The seal rubber comprises the following raw materials by weight: 50 to 60 parts of acrylic rubber, 10 to 15 parts of fluorinated silicone rubber, 10 to 15 parts of epichlorohydrin rubber T3100, 10 to 15 parts of butyl bromide rubber 221, 30 to 36 parts of high wear-resisting carbon black N330, 20 to 24 parts of precipitated white carbon black, 4 to 6 parts of light calcium carbonate, 5 to 10 parts of wollastonite in powder, 3 to 5 parts of zirconium tetrafluoride, 5 to 7 parts of barium sulfate, 3 to 5 parts of molybdenum disulfide, 9 to 11 parts of modified iron tailings powder, 1 to 2 parts of vulcanizing agent DCBP, 1 to 2 parts of antioxidant TPPD, 0.5 to 1 parts of accelerant H, 4 to 6 parts of magnesium oxide, 1 to 2 parts of 2-thiol benzimidazole, 1 to 2 parts of paraffin, 1 to 2 parts of isopropyl tri(dioctylpyrophosphate) titanate, and 17 to 19 parts of tri(2-ethylhexyl) acetocitrate. The rubber compound is excellent in ozone resistance, low-temperature resistance and heat resistance, wide in operating temperature wide and environment-friendly in process, and can be used for manufacturing various sealing gaskets.

Description

technical field [0001] The invention relates to the field of synthetic rubber, in particular to a gasket rubber material for automobile valves and a preparation method thereof. Background technique [0002] Rubber parts for automobiles play a major role in anti-vibration, noise reduction, driving stability and ride comfort of vehicles. The amount of general-purpose rubber materials used in automobiles is relatively large, but as the engine tends to develop in the direction of high power and miniaturization in recent years, the ambient temperature around the engine has increased, and the emission control regulations have become more stringent. In addition, the use of alcohol-containing fuels has forced rubber Parts improve heat resistance, cold resistance, oil resistance, aging resistance and other properties. Therefore, the consumption of high-performance special synthetic rubber is increasing, and automobiles are the main market for these special synthetic rubbers. Theref...
