Abstract
The invention relates to rubber for shaft sleeves. The rubber is prepared from the following raw materials in parts by weight: 60-80 parts of butadiene-acrylonitrile rubber, 6-9 parts of softening plasticizer, 8-11 parts of foamer, 4-9 parts of nano white carbon black, 2-5 parts of catalyst, 3-6 parts of vulcanizing agent, 7-12 parts of naphthenic oil, 6-9 parts of zinc borate, 2-4 parts of sulfur and 1-3 parts of reinforcing powder. The rubber has the beneficial effects that the rubber material disclosed by the invention is good in heat resistance and is not prone to aging deformation.
Description
technical field [0001] The invention relates to a rubber for a shaft sleeve, which belongs to the technical field of rubber. Background technique [0002] The shaft sleeve assembly is composed of shaft sleeve, rubber parts and iron sheet. During the production of the shaft sleeve assembly, the aluminum sleeve and iron sheet are processed first, and then the shaft sleeve, iron sheet and rubber are put into the vulcanization molding of the shaft sleeve assembly. High temperature vulcanization molding in the machine. The existing rubber used to make the shaft sleeve assembly is ordinary rubber, and its shortcomings are: (1) poor heat resistance, so the vulcanization temperature is low during high-temperature vulcanization molding, resulting in long vulcanization time and low processing efficiency; 2) The aging resistance and bonding strength are low. After vulcanization and molding, the adhesive force between the rubber part and the metal bushing and iron sheet is not enough, ...
