Abstract

The invention provides a rubber sealing material for an automobile. The rubber sealing material is composed of the following components in parts by mass: 65-70 parts of natural rubber, 20-30 parts of chloroprene rubber, 2-3 parts of stearic acid, 2-3 parts of methyl hydrogen silicon oil, 0.3-0.5 part of ethylene glycol, 0.5-0.8 part of calcium carbonate, 0.6-0.8 part of oleic diethanolamine borate, 4-6 parts of magnesium dimethacrylate, 3-5 parts of drying alkyd resin, 1-2 parts of paraffin, 1.3-1.6 parts of diethanolamine borate, 2-4 parts of diacetyl peroxide, 8-10 parts of zinc oxide, 6-8 parts of white carbon black, 0.5-2 parts of an anti-aging agent and 1-3 parts of sulfur. The invention also provides a preparation method of the rubber sealing material. The rubber sealing material for the automobile, provided by the invention, has favorable fatigue resistance and is suitable for sealing all parts of the automobile.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a rubber sealing material for automobiles. Background technique [0002] Automobile rubber seal strip is one of the important parts of the car, widely used in the door, window, body, seat, sunroof, engine box and trunk, etc., with waterproof, sealing, sound insulation, dustproof , antifreeze, shock absorption, warmth and energy saving. It must have strong tensile strength, good elasticity, and relatively good high temperature resistance and aging resistance. Existing rubber sealing materials for automobiles have poor fatigue resistance. Contents of the invention [0003] The invention provides a rubber sealing material for automobiles, and for this purpose, the invention also provides a preparation method thereof. [0004] The invention provides a rubber sealing material for automobiles. The rubber sealing material is composed of the following component...
