Problems solved by technology

[0004] At present, some peelable adhesives can be seen on the market, but they are generally only applied to transparent conductive glass in touch screens and ITO coatings of thin films, which play the role of insulation, moisture resistance and protection, and are also used for insulation protection of circuit boards, etc. However, the peeling force of these peelable adhesive coatings is too small, and the peelable protective film coatings are prone to warping, bubbling and other undesirable phenomena during the manufacturing process, which cannot meet the requirements of irregular-shaped metal parts (spectacle frames, etc.), plastics, Process protection for smooth surfaces such as sun lenses and curved glass

Embodiment 1

[0029] (S1) Preparation of peelable adhesive coating composition: 112g of aliphatic urethane acrylate W4048 (manufactured by Guangzhou Wuxing Materials Co., Ltd.), 8g of tris (2-hydroxyethyl) isocyanuric acid triacrylate THEICTA were put into a 500ml shading bucket (manufactured by Double Bond Chemical Co., Ltd.) and 40g ethyl acetate, stirred evenly with a high-speed disperser. Then add 1.1g leveling agent 9137 (manufactured by Double Bond Chemical Co., Ltd.), 4.5g low surface tension affinity auxiliary agent acryloyl morpholine, 2.4g anti-blocking agent MEK-AB-402 ( Nano silica slurry, manufactured by Nissan Chemical Co., Ltd.) and 6g photoinitiator 184 (manufactured by Tianjin Tianjiao Chemical Co., Ltd.). After the addition, stir at a high speed of 1200rpm for 60 minutes, then let it stand for more than 60 minutes to defoam naturally, obtain a peelable adhesive coating composition and dilute the peelable adhesive viscosity to 50±5cps with 70g of ethyl acetate;

Abstract

The invention provides a peelable glue coating composition, a peelable glue coating and application thereof. The peelable glue coating composition is prepared from, by weight, 80-120 parts of an acrylate oligomer, 8-20 parts of a dilute monomer, 2.5-12.5 parts of a low-surface-tension compatible additive, 2-12 parts of an initiator and 70-140 parts of an organic solvent. The peelable glue coating formed by conducting thermal curing or UV curing on the peelable glue coating composition has good adhesion to the surface of a part, easily and tightly adheres to the surface of the part, and the defects of shedding, bubbling, edge warping and the like caused by a variety of physical factors in the preparing process are not produced. In addition, when the peelable glue coating is needed to be peeled from the surface of the part, the peelable glue coating is easy to peel while no residue is formed on the surface of the part.

Description

technical field [0001] The invention relates to the field of manufacturing protective layers for metal parts, and in particular to a peelable adhesive coating composition, a peelable adhesive coating and applications thereof. Background technique [0002] At present, during the process of forming various irregular metal-plated parts, plastics, glass and other parts on the market, the surface is easily damaged by physical factors such as scratches. The general practice of manufacturers is to paste a layer of PE on these parts. Protective film to prevent it from being damaged during the production process. However, due to irregular parts, in the process of pasting the protective film, the PE protective film needs to be cut into strips of various specifications, and the film needs to be manually pasted, which is time-consuming, laborious and inefficient. Therefore, there is an increasing need for a A new type of protective film to solve the above problems. [0003] The proble...
