Abstract

The invention discloses a high-temperature resistant and aging resistant rubber sealing strip material for a vehicle and a preparation method thereof. The high-temperature resistant and aging resistant rubber sealing strip material for the vehicle is prepared from the following raw materials: natural rubber, ethylene-propylene-diene monomer rubber, ethylene-butene elastomer, anti-aging agent BLE, jojoba oil, chloropropyltriethoxysilane, dibutyl phthalate, di-n-butyl dimethly thiodiglycolate, triethanolamine, stearic acid, accelerant DPTT, zinc oxide, nano antimony tin oxide, epoxidized soybean oil, cordierite powder, sulphur, calcined loess and the like. The used ethylene-propylene-diene monomer rubber has an excellent sealing function, better agint resistant performance and good weather resistant performance; the added ethylene-butene elastomer is beneficial to improving the impact elasticity of the overall rubber material; the added anti-aging agent BLE and the nano antimony tin oxide are beneficial to enhancing the aging resistant performance of the rubber; with the reasonable coordination of the other additives, the heat resistant performance, the abrasion resistance and the elasticity of the rubber are improved, and favorable compression deformation resistant performance and sealing performance of the rubber material are played, so that the material is safer.

Description

technical field [0001] The invention relates to a rubber material, in particular to a high-temperature-resistant and anti-aging rubber sealing strip material for vehicles and a preparation method thereof. Background technique [0002] Rubber has many excellent properties such as good high and low temperature resistance, ozone resistance, weather resistance, insulation and production inertia, and is widely used in various fields of the national economy. Seals are materials or parts that prevent fluid or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from invading the internal parts of the machine. Although the rubber and plastic seal is small, its function makes it a basic component and accessory in the main industries of the national economy such as national defense, chemical industry, petroleum, coal, transportation and machinery manufacturing, and occupies a very important position in the development of t...
