Abstract
The invention discloses an anti-cracking synthetic rubber for a color selector. The anti-cracking synthetic rubber is prepared from the following raw materials in parts by weight: 40-60 parts of vinyl silicone rubber, 2-3 parts of stearic acid, 3-5 parts of calcium carbonate, 30-40 parts of white carbon black, 2-3 parts of diethylenetriamine, 3-5 parts of benzoyl peroxide, 25-35 parts of isoprene rubber, 2-3 parts of an accelerant CZ, 1-3 parts of magnesium carbonate, 5-8 parts of coumarone- indene resin, 1-2 parts of an anti-ageing agent PPD, 2-4 parts of a silane coupling agent KH-550, 1-3 parts of polyisobutene, 2-3 parts of triethyl citrate and 8-12 parts of modified kaolin. The anti-cracking synthetic rubber disclosed by the invention can be used for substituting a common spring used in a vibrator of an existing color selector to achieve a relatively good damping effect. Polyisobutene added to the synthetic rubber disclosed by the invention can be used for prolonging the storage period of the rubber, stabilizing viscosity at various temperatures, providing permanent flexure and resisting cracking. Meanwhile, the coumarone-indene resin further can be used for tackifying and strengthening the rubber.
