Material formula of shock-absorbing and wear-resistant rubber composition

Abstract

The invention discloses a material formula of a shock-absorbing and wear-resistant rubber composition. The material formula includes natural rubber, chlorhydrin rubber, butyl rubber, chloroprene rubber, zinc oxide, stearic acid, paraffin, a vulcanizing agent, an anti-aging agent, metal fiber filaments, a reinforcing agent and a plasticizer. The raw material composition comprises the following components: by weight: 90-100 parts of the natural rubber, 20-30 parts of the chlorhydrin rubber, 10-15 parts of the butyl rubber, 20-25 parts of the chloroprene rubber, 5-6 parts of the zinc oxide, 1-2 parts of the stearic acid, 0.5-1 part of the paraffin, 2-3 parts of the vulcanizing agent, 0.7-0.9 part of the anti-aging agent, 2-4 parts of the metal fiber filaments, 3-5 parts of the reinforcing agent, and 3-5 parts of the plasticizer. Rubber prepared by the rubber formula of the invention has the advantages of strong ageing resistance, improved wear resistance, long use life, good flame resistance and environmental protection. The rubber has a wider range of vibration isolation frequency, is improved in shock resistance and can better absorb mechanical vibration.

Rubber: A highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under a small external force. After removing the external force, it can return to its original shape. Rubber is a completely amorphous polymer. Its vitrification The transition temperature is low, the molecular weight is often very large, greater than hundreds of thousands, and the existing rubber has poor aging resistance, poor flame retardancy, poor wear resistance, and poor shock resistance.
