Abstract

The invention relates to the technical field of fine chemical engineering and particularly relates to an inorganic high-temperature corrosion-resistant lubricating coating. A dry-film lubricant is prepared from the following materials in percentage by weight: 10-30% of acidic aluminum phosphate, 10-20% of rare earth fluoride, 1-5% of polyvinyl formal, 2-8% of lead oxide, 1-5% of dimethylformamide, 1-3% of ferroferric oxide and 20-40% of a mixed solvent. The invention aims to provide a metal antirust dry-film lubricant which is energy-saving, environment-friendly and has comprehensive effects.

Description

technical field [0001] The invention relates to the technical field of fine chemical industry, and describes an inorganic high-temperature anti-corrosion lubricating coating. Specifically, the invention describes a coating suitable for heat processing molds and parts at room temperature to 500°C, and having excellent anti-sticking, anti-wear, anti-friction and lubricating properties. . Background technique [0002] High-temperature anti-corrosion lubricating coating is a special coating, which uses titanium nitride to adhere solid lubricant and its filler to the metal substrate, so as to play the role of anti-sticking and lubricating. At present, most of the high-temperature anti-corrosion and lubricating coatings used at temperatures above 400°C use inorganic titanium nitride such as silicate and phosphate. In the demoulding process of thermal processing, such as the production of TV glass shells, high-temperature lubricants need to be wiped on the mold on site to ensure ...
