Organic silicon pressure-sensitive surface coating

Abstract

The invention relates to an organic silicon surface coating, and in particular relates to an organic silicon pressure-sensitive surface coating which is prepared from the following raw materials in parts by weight: 35-40 parts of methyl chlorphenyl silicon oil, 7-15 parts of PEG-8 dimeticone water-soluble siloxane, 4-10 parts of stannous oxide, 5-15 parts of tetrabutyl titanate, 0.5-0.8 part of propargyl alcohol, 15-25 parts of pentaerythritol ester and 5-15 parts of azo dioctyl phthalate diisopropyl ester. By adopting the organic silicon pressure-sensitive surface coating provided by the invention, a micro-pore type organic silicon surface coating with a micro-pore structure is achieved, the organic silicon surface coating has the air exhaust property and the adsorbability, and meanwhile as the micro-pores are hollow, a function of adsorbing small molecules is achieved.

Description

technical field [0001] The present invention relates to silicone surface coatings, especially silicone pressure sensitive surface coatings. Background technique [0002] Silicone surface coating has excellent high and low temperature resistance, water resistance, corrosion resistance, atmospheric aging resistance and other characteristics, and is mainly used in sealing, bonding, coating, waterproof, moisture-proof, inert filling, etc. The silicone 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 silicone surface coating protective film is attached to the surface for protection, because the silicone surface coating layer is flat and tight, the surface to be protected and the organic There is no exhaust c...

Problems solved by technology

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