Abstract

The invention discloses a high cold-resistant acrylate rubber material and a preparation method and application thereof. The high cold-resistant acrylate adhesive material is prepared from 80 to 88 parts by weight of acrylate rubber, 10 to 16 parts by weight of nitrile rubber, 2 to 4 parts by weight of silicone rubber, 18 to 22 parts by weight of white carbon black, 1.5 to 1.9 parts by weight of stearic acid, 1.1 to 1.5 parts by weight of a plasticizer TOTM, 1.6 to 2.1 parts by weight of octyl silane bonded silica gel, 14 to 17 parts by weight of silicon micro-powder, 1.0 to 1.5 parts by weight of an antiager 445, 1.8 to 2.4 parts by weight of an antiager RDA, 6.5 to 7.3 parts by weight of N, N'-bis(cinnamal-1, 6-hexamethylenediamine), 2.2 to 2.6 parts by weight of an accelerator BG, and 0.7 to 1.0 part by weight of an accelerator ZDC. Through combination of nitrile rubber, silicone rubber and acrylate rubber, the high cold-resistant acrylate rubber material meets requirements on oil, heat, cold and aging resistance of an automotive oil return pipe.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a high cold-resistant acrylic rubber compound and its preparation method and application. Background technique [0002] The function of the oil return pipe of the car is to return the excess oil to the fuel tank, which can relieve the pressure of gasoline and reduce fuel consumption; after the fuel pump supplies fuel to the engine, a certain pressure is formed. It is sent back to the fuel tank through the oil return line, and of course the excess gasoline vapor collected by the carbon tank is also returned to the fuel tank through the oil return line. Therefore, when selecting the material of the oil return pipe of the automobile, it must have excellent oil resistance and high temperature resistance at the same time. In addition, it must also have certain low temperature resistance and aging resistance. [0003] Acrylate rubber (hereinafter referred to as ACM) is an elasto...
