Due to the residues of chemical substances, solvents and small molecules on the surface of the material, when the existing metal surface coating system protective film is attached to the surface for protection, because the metal surface coating is flat and tight, the surface to be protected and the metal surface coating There is no exhaust channel between them, and the residual small molecular substances cannot be discharged when they volatilize. Since the silica gel is airtight, there will be bad phenomena such as color difference and ring printing.

Abstract
The invention relates to a metal surface coating, in particular to an aluminum alloy surface-protecting agent. The aluminum alloy surface-protecting agent is prepared from the following raw materials, by weight, of 35-40 parts of methyl-ethyloxy silicone oil, 7-15 parts of silicon resin, 4-10 parts of N-phenyl anthranilic acid, 5-15 parts of tetrabutyl titanate, 0.5-0.8 part of dimethyl phosphate, 15-25 parts of pentaerythritol esters and 5-15 parts of diisopropyl azodicarboxylate. According to the aluminum alloy surface-protecting agent, the micro-porous metal surface coating with a micropore structure is achieved, the metal surface coating has exhaust performance and adsorptivity, and meanwhile, micropores are hollow and have the function of absorbing micromolecules.
Description
technical field [0001] The invention relates to a metal surface coating, especially an aluminum alloy surface protective agent. Background technique [0002] Metal surface coatings have excellent high and low temperature resistance, water resistance, corrosion resistance, and atmospheric aging resistance. They are mainly used in sealing, bonding, coating, waterproofing, moisture-proofing, and inert filling. The metal surface coating protective film made of silicone surface coating is mainly used to protect the surface of glass, metal sheet, plastic sheet and other materials from contact pollution or abrasion marks. Due to the residues of chemical substances, solvents and small molecules on the surface of the material, when the existing metal surface coating system protective film is attached to the surface for protection, because the metal surface coating is flat and tight, the surface to be protected and the metal surface coating There is no exhaust channel between them, a...
