Abstract

The invention discloses rubber for a truck bumper. The rubber comprises the following components in parts by weight: 80 parts of chlorosulfonated polyethylene, 52 parts of acrylonitrile-butadiene rubber, 8-19 parts of fast extruding carbon black, 10-15 parts of pyrolysis carbon black, 2-4 parts of indirect zinc oxide, 1-8 parts of magnesium oxide, 0.2-1 part of diethyl aminodithioformic acid, 0.4-1.5 part of thiodipropionic acid biglycerol trilaurate, 0.5-1 part of zinc stearate, 2-4 parts of 2,2'-dithiobisbenzothiazole, 0.3-0.5 part of trithiocyanuric acid, 5-8 parts of trioctyl trimellitate, 1-5 parts of magnetism strong powder, 2-3 parts of sulphur and 1-3 parts of butyl chloride. According to the rubber for the trunk bumper, the defects of poor high-temperature resistance performance, easy aging, short service life and the like in the prior art can be overcome, and the advantages of high high-temperature performance, difficulty in aging and long service life are realized.

Description

technical field [0001] The invention relates to automobile rubber hose technology, in particular to a rubber used for truck bumpers. Background technique [0002] Rubber is an elastic polymer. Rubber can be obtained from the sap of some plants, or it can be man-made. Both have quite a lot of applications and products, such as tires, gaskets, etc., and have become important economic crops. Rubber plantations are mainly concentrated in Southeast Asia, such as Thailand, Malaysia, and Indonesia. [0003] After rubber was introduced to Britain, people found that this material could effectively wipe off the traces left by pencils, so the eraser was invented. The English name of rubber is rubber. In 1770, Priestley, England, discovered that this substance could erase (rub off) pencil marks. According to the different ways of making, rubber can be divided into two categories: synthetic rubber and natural rubber. [0004] In the process of realizing the present invention, the inv...
