Abstract

The invention relates to a dissimilar metal connector anticorrosive lubricating coating for metal composite structures. The coating comprises the following material components in parts by weight: 2000-4000 parts of molybdenum disulfide, 0-180 parts of strontium chromate, 2000-6000 parts of heat-resistant phenolic resin, 4000-5000 parts of ethylene glycol ethyl ether acetate, 0-200 parts of polytetrafluoroethylene, 30-50 parts of bentonite, 100-150 parts of a polyamide wax liquid modifier aid and 10-30 parts of a leveling aid. The dissimilar metal connector anticorrosive lubricating coating forthe metal composite structures, which is provided by the invention, is applicable to anticorrosive treatment on surfaces of dissimilar metal connectors for metal composite structures such as an aluminum alloy and a titanium alloy, and has high temperature resistance, paint remover resistance and self-lubricating properties.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion lubricating coatings, in particular to anti-corrosion lubricating coatings for heterometallic connectors used in metal composite structures. Background technique [0002] Stainless steel, aluminum alloy and titanium alloy fasteners have been widely used in high-end metal structure connectors in the fields of aviation and rail transportation, such as magnetic levitation rail systems, due to their excellent comprehensive properties such as high specific strength, fatigue resistance, and corrosion resistance. Highly alloyed alloy steel composite structure. Anti-galvanic corrosion-resistant stainless steel, anti-corrosion coatings for aluminum alloy and titanium alloy fasteners have special requirements for assembly processes in many fields. The aviation industry uses fasteners and other connecting parts to realize mechanized assembly, and requires that after long-term use, there will be no ag...
