The utility model has the advantages that the present invention carries out rational proportion by the raw material to self-priming chemical pump rubber seal, can make
The self-priming chemical pump rubber seal that must be had excellent performance, is acted synergistically by each component, the chemical pump rubber seal of preparation
Part has excellent tensile strength, hardness and brittleness temperature, can adapt to the working environment of Various Complex, service life obtains
It greatly ensures, by acting synergistically in sulphur and tetrahydrofurfuryl amine modified butadiene acrylonitrile rubber, so that the linear high score in rubber material
Son becomes net high-polymer, forms fine and close network structure, improves the performance for thinking rubber seal, then passes through Lanthanum Stearate again
Modified powdered carbon is evenly dispersed wherein, combines on the macromolecular chain of net high-polymer, not only plays profit to rubber seal
Sliding, antifriction effect, while the coefficient of friction between dynamic rubber seal and mechanical part can be reduced, frictional heat generation is reduced,
To reduce the operating temperature of sealing element, rubber heat-proof aging degree is reduced, improves seal durability, also, the system that rubs
After number reduces, the frictional force or friction torque that the dynamic rubber seal and mechanical part of relative motion are shown in reduce, to reduce
Power loss reaches energy-saving and environment-friendly purpose, and tetrahydrofurfuryl amine modified butadiene acrylonitrile rubber makes intermolecular Electronic interactions,
Mobility, the plasticity of rubber are improved by reducing the active force between rubber molecule, meanwhile, nitrile rubber sealing can be improved
The resistance to low temperature of part, the modified powdered carbon of Lanthanum Stearate can be the Physical Network lineations between rubber after being distributed to nitrile rubber molecule centre
It opens, to have the function that improve low temperature resistant.
