Abstract

The invention provides a rubber material for sealing an automobile door. The rubber material is composed of the following components in parts by mass: 70-80 parts of natural rubber, 20-30 parts of hydrogenated butadiene-acrylonitrile rubber, 3-5 parts of stearic acid, 2-3 parts of methyl hydrogen silicon oil, 1.5-1.8 parts of light calcium carbonate, 0.4-0.6 part of oleic diethanolamide borate, 3-5 parts of drying alkyd resin, 1-2 parts of paraffin, 0.5-0.8 part of glass fiber, 0.8-1.2 parts of zinc diethyldithiocarbamate, 2-4 parts of acetyl peroxide, 8-10 parts of aluminum oxide, 10-15 parts of white carbon black, 0.8-1.5 parts of an anti-ageing agent and 1-3 parts of sulfur. The invention also provides a preparation method of the rubber material. The rubber material provided by the invention has favorable ageing resistance and sealing performance and can be favorably applied to sealing of the automobile door.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an automobile door sealing rubber material. 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. The existing automobile door sealing rubber material has poor aging resistance. Contents of the invention [0003] The invention provides an automobile door sealing rubber material; therefore, the invention also provides a preparation method thereof. [0004] The invention provides an automobile door sealing rubber material. The rubber material is composed of the following components in parts by ma...
