Abstract

The invention discloses a sealing paste, and belongs to the technical field of chemical engineering in order to solve the problem of influence of unable formation of a thick and stable oil film due to poor adhesiveness of present sealing pastes on the sealing performance of devices. The sealing paste comprises a common grease and a copper-based composite powder material uniformly dispersed in the common grease, a mass ratio of the copper-based composite powder material to the common grease is 0.5-20:100, and the particle size of the copper-based composite powder material does not exceed 30[mu]m. The sealing paste can greatly improve the adhesion performance of the sealing paste on the working surface of a machine to form a thick and stable oil film in order to improve the sealing performance.

Description

[0001] This application claims the priority of Chinese patent application numbers 2014106901783 and 2014106917103 submitted on November 25, 2014. technical field [0002] The invention belongs to the technical field of chemical industry and relates to materials for adhesion and sealing, in particular to a sealing paste which can be used to seal the gaps of mechanical equipment. Background technique [0003] The sealing paste is made of liquid polysulfide rubber as the base material. It is a polysulfide sealing paste that can be self-vulcanized and cross-linked at room temperature. It has good adhesion to metals and concrete and other materials, and maintains good performance under vibration and high temperature Excellent air tightness and water resistance, and oil resistance, solvent resistance, durability is very good. [0004] Since the sealing paste contains semi-solid lubricating grease, it has the following advantages compared with the sealing oil mainly composed of lub...
