Abstract

The invention provides antistatic rubber material and a preparation method thereof, wherein the antistatic rubber material contains antistatic agent of 3 to 5 weight percent with reference to rubber matrix of 100 weight percent; the antistatic agent is a mixture and comprises compositions according to the following weight ratio: emulsifying agent: polar solvent: organic amine: metal salt is equal to 3:3:1-2:1-2; and the metal salt is selected from lead acetate, mercury bichloride, copper sulphate, iron chloride, antimonic chloride, stannic chloride or silver nitrate. The rubber material prepared by the antistatic agent has excellent antistatic performance, surface resistivity reaching 10<6> ohm to 10<8> ohm as well as high-efficient and persistent static resistance; moreover, the rubber material has ideal compatibility with other additives of rubber products, thereby meeting the requirements of high temperature during manufacturing the rubber products without influencing the physical property and the chemical property of one another.

Description

technical field [0001] The invention relates to a rubber material containing an antistatic agent and a preparation method thereof. Background technique [0002] Rubber is the basic raw material of the rubber industry and is widely used in the manufacture of tires, hoses, tapes, cables and other rubber products. Rubber has excellent insulating properties, which will cause a large amount of static electricity to accumulate, which is a serious defect in the application of its products in the electronics industry. For example: These static electricity will generate gravitational force and absorb dust, pollute integrated circuits and semiconductor components, and greatly reduce the yield of electronic products; electrostatic discharge will cause failure or malfunction of electronic equipment, causing electromagnetic interference; high-voltage electrostatic discharge will cause Electric shock, causing explosion and fire, endangering personal safety. Therefore, how to reduce and ...
