Abstract

The invention discloses application of the base coating and roller coating technology for the surface of a metal air cylinder gasket. The application comprises the following steps that (1) materials are collected; (2) a stainless steel material is punched; (3) sand blasting treatment is conducted on the surface of a workpiece, and then the workpiece is soaked with 5% hydrochloric acid and washed with clear water; (4) the cleaned workpiece is dried; (5) a stainless steel base coating agent is sprayed to the cleaned workpiece; (6) the workpiece in the step (5) is dried; (7) fluoro rubber is sprayed to the dried workpiece in the step (6); (10) the bonding surface of the embossed workpiece is cleaned with a 50% acetone solution; (11) the workpiece in the step (10) is subjected to roller coating through the stainless steel base coating agent; (12) the workpiece in the step (11) is dried; and (13) the dried workpiece is riveted. According to the application of the base coating and roller coating technology for the surface of the metal air cylinder gasket, the stainless steel base coating agent is adopted, the adhesive force between the fluoro rubber and stainless steel is improved, a fluoro rubber adhesive is subjected to roller coating, and the surface elasticity of the fluoro rubber is improved.

Description

technical field [0001] The invention relates to the technical field of surface treatment of metal cylinder head gaskets, in particular to the application of primer coating and roll coating technology on the surface of metal cylinder head gaskets. Background technique [0002] At present, the metal cylinder gasket is formed by stamping several layers of stainless steel, printing fluorine rubber on the surface, corrugating, riveting or welding. [0003] Since the fluororubber is directly printed on the surface of the stainless steel, the adhesion of the fluororubber printed on the surface of the existing metal cylinder head gasket cannot meet the requirements, and it will fall off during the seal, thus causing the seal to fail. Contents of the invention [0004] The purpose of the present invention is to provide a primer and roll coating technology application on the surface of the metal cylinder head gasket to solve the problem that the adhesion of the fluororubber proposed...
