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.
