Abstract

The invention discloses grease used for a metal fastener, which is prepared from the following components in percentage by weight ( in percentage by total weight of the grease): 50.0 to 90.0 percent of basic grease, 1.5 to 20.0 percent of film-forming agent, 0.1 to 1.0 percent of anti-oxidation preservative, 5.1 to 8.3 percent of anti-rust agent and 2.5 to 26.0 percent of solid stuffing. The grease has higher oxidation resistance, higher corrosion and rust resistance, better water resistance, more excellent sealing property, better pressure resistance, better adhesivity, more environment-friendly suitability, convenient brushing and injection and stable structure and is not easy to generate swelling action on protected nonmetal assorted components. The grease can be largely applied to thespeed acceleration of the trunk line of the railway ballastless track.

Description

technical field [0001] The present invention relates to a kind of grease, in particular to a kind of grease used for antirust, anticorrosion and sealing of metal fasteners. Anti-rust, anti-corrosion and sealing of outdoor crane fastening fasteners, construction fasteners, metallurgical fasteners, oil pipelines and other equipment components (such as spikes, bolts, threads, etc.). Background technique [0002] The multi-series concrete sleepers of my country's railways are laid, and the fasteners, sleepers, and switch sleepers are connected by sulfur anchorage. The protection of this kind of track fastening fasteners is traditionally made of calcium-based grease (butter) for anti-corrosion protection. There are also Use waste engine oil or mixed with asphalt to heat, or grease that has not been verified and strictly inspected for anti-corrosion protection. In recent years, my country's railway construction has developed rapidly, and the speed of railways has been increased si...
