Abstract

The invention discloses a rubber part of an automobile gas inlet pipe, and belongs to the technical field of automobile rubber parts. The rubber part is prepared from the following raw materials in parts by weight: 100 parts of nitrile rubber, 20-30 parts of fast extruding furnace black, 10-15 parts of cracking carbon black, 5-10 parts of indirect zinc oxide, 1-2 parts of zinc diethyl dithiocarbamaate, 1-2 parts of thiodipropionate di-glycerol trilaurate, 1-3 parts of zinc stearate, 3-5 parts of ethidene diamine, 0.5-0.8 part of trithiocyanuric acid, 1-3 parts of paraffin and 0.1-0.2 part of sulfur. Compared with outer-layer rubber of an automobile fuel oil rubber pipe in the prior art, the rubber part disclosed by the invention has the advantages that under the synergistic effect of all raw material components, the ozone resistance of the rubber part is effectively improved, and the fuel resistance of the rubber part is improved.

Description

technical field [0001] The invention relates to the technical field of rubber parts for automobiles, in particular to an automobile air intake pipe rubber part. 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 pipe rubber, and mixes with the gasoline sprayed from the fuel injector to form a proper proportion of oil and gas. The oil and gas pass through the intake valve. Send it into the cylinder to ignite and burn to generate power. [0003] With the continuous improvement of people's living standards and the continuous development of the automobile industry, people's performance requirements for various parts of the automobile are also continuously improved, and the rubber parts of the automobile intake pipe is one of them. At present, the existing air intake pipe rubber parts in China have problems such as tensile strength, elongation, flex res...
