Abstract

The invention relates to the technical field of rubber seal processing, and discloses an antistatic rubber seal material, the antistatic agent used and polydimethylsiloxane, epoxidized polyamide resin, polyvinyl alcohol, polyethyleneimine Curing at the same time, compared with the antistatic agent directly coated on the surface of the product, the method of the present invention combines the antistatic component with the material, and under the directional action of the antistatic agent, lipophilic groups will be formed on the surface of the polymer. The dense monolayer of antistatic agent with the hydrophilic group facing outward can reduce the overall resistance and prevent charge accumulation, achieve structural antistatic effect, and have excellent durability.

Description

technical field [0001] The invention belongs to the technical field of rubber seal processing, and in particular relates to an antistatic rubber seal material. Background technique [0002] Rubber seals are a common basic component in sealing devices, and play a very important role in the contradiction between leakage and sealing. Rubber, together with plastic and fiber, is called the three major synthetic materials, and is the only polymer material with high elasticity and excellent elasticity. The biggest feature of rubber is that the modulus of elasticity is very small and the elongation is very high. The second is that it has fairly good gas permeability resistance, resistance to various chemical media and electrical insulation properties. Some special synthetic rubbers have good oil resistance and temperature resistance, and can resist the swelling of fatty oil, lubricating oil, hydraulic oil, fuel oil and solvent oil; cold resistance can be as low as -60 ° C to -80 °...
