Problems solved by technology

However, when the silane film itself is porous and has weak corrosion resistance to corrosive media, in a corrosive environment, Cl-, etc. are particularly prone to corrosion along these defects. Peel off, so that once the silane film is damaged, it cannot be self-repaired, and it is easy to cause corrosion of the metal substrate

Abstract

The invention discloses an aluminum alloy sodium soap grease cured film forming solution. The solution is composed of, by weight, 1-2 parts of myristic acid, 0.1-0.3 part of polydimethylsiloxane, 3-4 parts of sodium soap grease, 100-110 parts of bis(gamma-triethoxysilylpropyl)tetrasulfide, 10-12 parts of butyl titanate, 0.8-1 part of calcium lactobionate, 3-5 parts of multiwalled carbon nanotubes, 0.8-1 part of cerous nitrate, 0.3-1 part of trimethylolpropane, 0.08-0.1 part of polytetrafluoroethylene, 1-2 parts of sodium pyrophosphate and 0.1-0.2 part of triethanolamine borate. The sodium soap grease treated by the polydimethylsiloxane is added into a cured film, friction on the surface of aluminum alloy can be lowered, and a good lubricating effect is achieved.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy surface treatment, in particular to an aluminum alloy sodium-based lubricating grease solidified film forming liquid and a preparation method thereof. Background technique [0002] Due to its unique molecular structure, non-toxic environmental protection, low cost, and good compatibility, silane has been used in the field of metal anticorrosion. After hydrolysis, silane can be tightly combined with the metal substrate, forming a dense film on the surface, which has a good protective effect on the metal. However, when the silane film itself is porous and has weak corrosion resistance to corrosive media, in a corrosive environment, Cl-, etc. are particularly prone to corrosion along these defects, and the accumulation of corrosion products at the interface will form a stress zone at the interface, causing the film layer Peel off, so that once the silane film is damaged, it cannot be self-rep...
