Description

technical field [0001] The invention relates to the technical field of insulating coating coatings, in particular to a high-temperature, high-humidity and high-pressure-resistant, acid-alkali-resistant and high-adhesion roll-spray coating. Background technique [0002] 1. The roll-spray paint currently used in the market is generally epoxy resin type, and its curing speed is slow during the roll-spray process, and the curing is achieved entirely by the volatilization of the solvent. [0003] 2. Traditional epoxy resin coatings for high-end electronic components, semiconductors and small precision hardware parts cannot solve the problems of high temperature, high humidity and high pressure, and the coating has low adhesion and cannot meet the requirements of low-halogen or even halogen-free environmental protection standards. [0004] 3. When high-end electronic components, semiconductors and precision hardware small parts are coated with a layer of insulating paint by roller...

AI Technical Summary

Problems solved by technology

[0002] 1. The roll-spray paint currently used in the market is generally epoxy resin type, and its curing speed is slow during the roll-spray process, and the curing is achieved entirely by the volatilization of the solvent

[0003] 2. Traditional epoxy resin coatings for high-end electronic components, semiconductors and precision hardware small parts cannot solve the problems of high temperature, high humidity and high pressure, and the coating adhesion is low, which cannot meet the environmental protection standards of low halogen or even halogen-free

[0004] 3. When high-end electronic components, semiconductors and precision hardware small parts are coated with a layer of insulating paint by roller spraying process, it needs to cooperate with high temperature roller spraying coating process. It is difficult to achieve uniform coating in the process of roller spraying for existing insulating coatings. Its poor adhesion makes the edges of the parts easy to wear and stick together, which can neither achieve the purpose of insulation nor meet the requirements of product quality
