Abstract
The invention discloses an elastic enhanced rubber gasket material which is characterized in that the material is prepared from the following raw materials by weight: 55-60 parts of epichlorohydrin rubber (H45), 20-25 parts of butyl rubber (CBK139), 5-11 parts of stearic acid, 1-2 parts of sorbitan stearate, 2-3 parts of triethanolamine, 1-2 parts of sodium diacetate, 1-2 parts of dibasic lead phosphate, 3-5 parts of zinc oxide, 1-2 parts of sulphur, 1-2 parts of zine stearate, 10-12 parts of bentonite, 12-15 parts of precipitation method white carbon black, 15-20 parts of N339 carbon black, and 10-12 parts of modified attapulgite. According to the invention, modified attapulgite is added, which improves rubber processing property; environment-friendly type compounding agents are used, which reduces toxic and side effects and environment pollution; the material of the invention has enhanced elasticity, and is excellent in sealing performance, good in aging resistance, simple in process, and low in cost.
Description
Technical field
The present invention relates to rubber composite manufacture field, particularly a kind of elasticity enhancement type rubber seal cushion material and preparation method thereof.
Background technology
Gasket is a kind of for the inside such as machinery, equipment, pipeline, the material sealing.The gasket using mostly at present is rubber gasket, be characterized in: high temperature resistant, resistance to ozone, resistance to natural weathering, vacuum-resistant, fuel oil resistance, resistance to lubricating oil, powerful oxidation corrosion resistance agent, resistance to chemical reagents and electrical insulation capability are good, are widely used in national defense industry and civilian industry.The defects such as but existing rubber gasket sealing effectiveness is undesirable, wear resistance is poor, intensity is low, far can not meet actual requirement.Therefore researching and developing a kind of high-performance rubber gasket has become the task of top priority.
