Abstract

An antisticking, antiwear and lubricating paint solidified at ordinary temp and with high load-bearing power is prepared from tetrafluorowax, polyurethane resin, Sb2O3, and melamine-tripolycyanate complex. Its advantages are high hardness, high adhesion, and wide temp range (-50-200 deg.C).

Description

technical field [0001] The invention describes a lubricating coating with high bearing capacity, anti-sticking and high wear resistance cured at room temperature. Specifically, the invention describes a novel high-load, long-life, wear-resistant lubricating coating suitable for dry friction and mechanical parts under the action of water medium under the film thickness requirement of 10 μm to 120 μm. Background technique [0002] Machinery, chemical industry, metallurgy, food and other industries work in dry friction and high-load mechanical parts (such as: gears, bearings, impellers, valves) under the action of water media. Due to high load and high speed, the wear is fast and serious. As a result, the working life of the equipment is shortened, the energy consumption of the equipment is increased, and the economic cost is too high. If a layer of room-temperature-cured high-load anti-stick and wear-resistant lubricating coating is applied to the friction parts, it not only ...
