Shock-absorption synthetic rubber and preparation method thereof

Abstract

The invention discloses a shock-absorption synthetic rubber which is prepared from the following raw materials in parts by weight: 10.5-12.6 parts of methyl methacrylate, 2.3-5.7 parts of silver-coated glass microsphere core-shell composite particle, 2.6-4.8 parts of rosin polyoxyethylene sulfonate, 1.5-1.8 parts of polyethyleneglycol octyl phenyl ether, 5.3-7.8 parts of ethyl 3-ethoxypropionate, 4.3-5.2 parts of pine tar, 2.5-3.7 parts of magnesium oxide and 1.3-1.8 parts of coupling agent. The environment-friendly rubber material has the advantages of simple formula and technique, low production cost, high damping, high elasticity and favorable high / low temperature resistance, and can not release bromides or other harmful substances. The rubber product can not generate any corrosive action on electronic components after being used for a long time. The shock-absorption synthetic rubber is especially suitable for manufacturing shock-absorption sleeves and other products of disk drives and other electronic and electric products. The shock-absorption synthetic rubber has high damping capacity, and thus, still has high shock absorption effect under the condition of strong shocks when the automobile runs at high speed or passes over a deceleration strip.

Description

technical field [0001] The invention relates to a rubber material and a preparation method thereof, in particular to a shock-absorbing synthetic rubber, which belongs to the field of rubber production. Background technique [0002] The traditional rubber production process uses rosin polyoxyethylene sulfonate vulcanization method, and in the industrial butyl vulcanization system, the presence of halogen elements is required to ensure complete vulcanization, so the rubber produced will continue to Harmful substances such as bromide, chloride, and sulfide are released, and these harmful substances will corrode electronic components such as circuits, IC pins, connectors, CD-ROMs, and cores that are mainly made of metal materials. It can cause electrical appliances to fail to operate normally or even be completely damaged. Therefore, world-class information manufacturers will never allow harmful substances such as bromide, chloride, and sulfide to exist in their products. Howev...

[0002] The traditional rubber production process uses rosin polyoxyethylene sulfonate vulcanization method, and in the industrial butyl vulcanization system, the presence of halogen elements is required to ensure complete vulcanization, so the rubber produced will continue to Harmful substances such as bromide, chloride, and sulfide are released, and these harmful substances will corrode electronic components such as circuits, IC pins, connectors, CD-ROMs, and cores that are mainly made of metal materials. It can cause electrical appliances to fail to operate normally or even be completely damaged. Therefore, world-class information manufacturers will never allow harmful substances such as bromide, chloride, and sulfide to exist in their products.

However, none of the existing rubber materials can meet the environmental protection requirements of no sulfur and extremely low halogen content, and cannot be well applied in the field of electronics and electrical
