Abstract
The invention discloses an anti-impact and shockproof rubber piece, and relates to the technical field of rubber product manufacturing. The anti-impact and shockproof rubber piece is prepared from 100 parts of butadiene-acrylonitrile rubber, 3-5 parts of activating agent, 0.5-1 part of accelerant, 2-3 parts of anti-aging agent, 70-75 parts of carbon black, 5-8 parts of vulcanizing agent, 5-8 parts of zincmethacrylate, 7-9 parts of P-tert-butyl phenolformaldehyde resin, 6-10 parts of plasticizer, 10-15 parts of paraffin and 10 parts of processing agent. Wear-resistant, oil-resistant and anti-ageing butadiene-acrylonitrile rubber serves as the body material; through the scientific and reasonable formula, the strength of the rubber piece is improved,; the produced anti-impact and shockproof rubber piece is high in impact resistance and long in service life; no damage is caused when continuous impact of 5 HZ is exerted at the two ends of the plane of the rubber piece for 2 hours during the acceleration test under the voltage of 380 V.
Description
technical field [0001] The invention relates to the field of rubber product manufacturing, in particular to an impact-resistant and shock-absorbing rubber part. Background technique [0002] Rubber Highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. The elasticity of rubber is produced by the change of its coiled molecular conformation. The interaction between rubber molecules will hinder the movement of molecular chains, and it also shows the characteristics of viscosity, so that the stress and strain are often in an unbalanced state. The curly long-chain molecular structure of rubber and the weaker secondary force between molecules make the rubber material exhibit unique viscoelastic properties, so it has good shock absorption, sound insulation and cushioning properties. Rubber parts are widely u...
