New type of pump seal gasket for environment-friendly vehicles

Abstract

The invention discloses a novel pump sealing gasket for an environmental-friendly vehicle, which is formed by mixing and preparing the following raw materials in percentage by weight: 5-8 percent of acrylon pulp, 25-40 percent of silicate fiber, 5-10 percent of nylon fiber, 15-35 percent of silicate packing, 8-12 percent of chloroprene rubber, 5-10 percent of natural rubber and 0.5-2.5 percent ofcuring system. Preferably, the novel pump sealing gasket is prepared by mixing the following raw materials in percentage by weight: 7 percent of acrylon pulp, 35 percent of silicate fiber, 7 percent of nylon fiber, 27 percent of silicate packing, 12.5 percent of chloroprene rubber, 9 percent of natural rubber and 2.5 percent of curing system. The novel pump sealing gasket for the environmental-friendly vehicle is formed by mixing the raw materials, carrying out sizing molding at one step and continuously rolling and vulcanizing by a plurality of rolls.

Description

technical field [0001] The invention belongs to the technical field of sealing gaskets, and in particular relates to a novel environment-friendly sealing gasket used for automobile pumps. Background technique [0002] Traditional automotive pump gaskets contain asbestos, which pollutes the environment and endangers human health. The product has poor resistance to deformation and relaxation, poor heat and aging resistance, poor flexibility, low compactness, poor sealing, and easy installation. fracture. The non-asbestosization of fiber-reinforced elastomer fluid sealing materials is an inevitable requirement for the development of environmental protection today. The patent number is 200410015794.5, the name is: Non-asbestos fiber reinforced latex gasket plate manufacturing molding process, the applicant is Shanghai University. Its molding process includes raw material preparation, that is, the preparation and formulation of various raw material components such as non-asbest...

AI Technical Summary

Problems solved by technology

Its molding process includes raw material preparation, that is, the preparation and formulation of various raw material components such as non-asbestos fiber, rubber emulsion, cross-linking agent, filler, auxiliary additives, non-asbestos fiber treatment, latex preparation, and county floating liquid preparation. , copy molding, drying and roll vulcanization, characterized in that: using a special ratio of raw material components, but the procedure is too complicated, and the quality of the obtained sealing gasket still has problems
