Abstract

The invention discloses an automobile oil return pipe glue stock and a preparation process thereof. The glue stock comprises, by weight, 70-85 parts of nitrile rubber, 15-30 parts of pyridine butadiene rubber, 20-25 parts of spraying carbon black, 1.2-1.5 of stearic acid, 2.0-2.8 parts of canola oil, 1.6-2.0 parts of dibutyl ester, 4-7 parts of sea-foam stone powder, 10-14 parts of quartz powder, 0.8-1.2 parts of anti-aging agents RD, 1.1-1.3 parts of anti-aging agents AW, 1.6-2.0 parts of anti-aging agents ODA, 6.5-7.8 parts of N,N'-meta phenylene bis maleimide, 0.20-0.27 parts of accelerator TMTD and 1.2-1.5 parts of accelerators DM. According to the automobile oil return pipe glue stock, the pyridine butadiene rubber and the nitrile rubber are compounded and used, and proper filling agents and the anti-aging agents are matched, so that the prepared glue stock meets requirements of oil resistance and heat resistance, cold-resistance and aging resistance of an automobile oil return pipe.

Description

technical field [0001] The invention relates to the technical field of automobile materials, in particular to a rubber material for an automobile oil return pipe and a preparation process thereof. 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] Nitrile rubber is produced by emulsion polymerization of ...
