Air feeder rubber member between engine oil cleaner and intake manifold of automobile, and manufacturing process thereof

Abstract

The invention discloses a rubber article of an air inlet pile used between a vehicle oil filter and an inlet manifold and the manufacturing technique thereof. The manufacturing technique comprises the following steps: firstly, 80 portions to 120 portions of nitrile rubber, 70 portions to 90 portions of cabon black, 5 portions to 10 portions of indirect process zinc oxide, 1.5 portions to 2.5 portions of zinc stearate, 5 portions to 7 portions of age inhibitor, 20 portions to 30 portions of TP-95, 3 portions to 5 portions of lubricant, 1 portion to 3 portions of antiozonant, 0.3 portion to 0.5portion of S-80, and 4 portions to 6 portions of accelerant are mixed and synthesized into rubber by a banbury mixer, then the qualified synthesized rubber is put into a mould in vulcanization equipment for vulcanizing treatment after being rolled and moulded. In the vulcanizing process which lasts for 360 to 480 seconds, the pressure is raised to 170 Kgf / cm<2>-190 Kgf / cm<2>, and the temperature is raised to 165 DEG C -175 DEG C; and finally, the rubber article after vulcanizing treatment is trimmed, tested and warehoused. The tensile strength, tensile elongation, tear resistance, flexing property, ozone resistance, heat and age resistance, and fuel resistance of the rubber article of the air inlet pile are all improved greatly and the good tightness is guaranteed.

Description

Technical field: [0001] The present invention mainly relates to a rubber part for automobiles, in particular to a rubber part of an intake pipe of a connecting piece between an oil filter and an intake manifold in an automobile power system and a manufacturing process thereof. Background technique: [0002] After the air is filtered by the air filter to remove impurities, it flows through the air flow meter, enters the intake manifold through the intake duct (rubber parts of the intake pipe), and mixes with the gasoline sprayed from the fuel injector to form a proper proportion of oil and gas. It is sent into the cylinder through the inlet valve for ignition and combustion to generate power. [0003] In recent years, with the continuous prosperity of the car market, consumers have higher and higher requirements for automobile exhaust emission control and speed increase, and higher requirements for intake pipes. Existing domestic rubber parts for air intake pipes have serious quali...

AI Technical Summary

Problems solved by technology

The existing domestic air intake pipe rubber parts have serious quality problems, such as tensile strength, elongation, flex resistance, ozone resistance, thermal aging resistance, fuel resistance, etc., which cannot meet the requirements. After 10,000 kilometers, the intake pipe will crack, causing the clean air to be polluted
