Abstract

The invention relates to grease, specifically to grease used for combustion gas plug valve lubrication and sealing and a preparation method thereof. The invention aims to provide the grease for a combustion gas plug valve. The invention also aims to provide a preparation method of the grease. By using a specific dispersion machine, the process is simple and easy to realize, is pollution-free, andhas a good industrial application prospect. The composition of the grease is synthetic oil, an inorganic densifier, a structure modifier, a cosolvent, an antioxidant, an antirust agent and a solid lubricant. By densifying special synthetic oil with the inorganic densifier and adding the special structure modifier and the cosolvent, the grease has good acid and base resistance, rubber compatibilityand mechanical stability, erosion of Co, methane, etc. in combustion gas and rubber expansion and shrinkage are prevented, and the temperature range is wide and is minus 40-200 DEG C. And the servicelife is long.

Description

technical field [0001] The invention relates to a lubricating grease, in particular to a lubricating grease used for lubricating and sealing a gas cock valve and a preparation method thereof. Background technique [0002] The industrial subdivision of gas stove parts and complete machines in my country was roughly completed in the 1990s. This is marked by the emergence of manufacturers of key components of controllers (cock valve assemblies), burners, pulse igniters and panel lights. After the first 15 years of development in this century, parts and components have gone through the growth period and began to enter the threshold of maturity, and formed a large number of industrial clusters with their own characteristics in the Pearl River Delta and the Yangtze River Delta. [0003] At present, most regions in my country have preliminarily completed the popularization of medium and low-grade gas stove products, but the differences in the regional distribution and sales volume...
