Problems solved by technology

[0003] However, traditional acrylic electric anti-adhesive (three anti-paint), containing benzene and aromatic solvents, has a pungent smell and is harmful to human health
Traditional acrylic electric anti-adhesive (three anti-paint), the curing mechanism is solvent volatilization and self-crosslinking (no chemical reaction), the formed paint film has low hardness, poor scratch resistance, poor salt spray resistance, and the temperature resistance is only -20~ 120℃ etc.

Abstract

The invention relates to the technical field of acrylic acid electric anti-gum agent, in particular to high-performance modified resin electric anti-gum agent which comprises, in weight percent, 30-49.8% of thermoplastic acrylic acid resin, 10-15% of cellulose acetate butyrate, 0.1-0.5% of silane coupling agents, 0.1-0.5% of acrylate copolymer flatting agents, 0-0.2% of fluorescent whitening agents and 40-59.8% of propylene glycol methyl ether acetate (PMA). The high-performance modified resin electric anti-gum agent takes a PMA solvent as a solvent, a benzene solvent is omitted, and the modified resin electric anti-gum agent is low in odor, environmentally friendly, high in paint film adhesive force, excellent in bonding strength, water resistance and salt spray resistance and the like.

Description

technical field [0001] The invention relates to the technical field of acrylic electric anti-adhesive, in particular to a high-performance modified resin electric anti-adhesive. Background technique [0002] Acrylic electrical anti-adhesive, also known as conformal paint, PCBA protective oil, PCBA waterproof adhesive, PCBA insulating paint, is a specially formulated coating used to protect circuit boards and related equipment from environmental erosion. In the actual application environment, such as chemical, vibration, dust, salt spray, humidity and high temperature, low temperature and other environments, the circuit board may have problems such as corrosion, softening, deformation, mildew, etc., which will cause the circuit board to malfunction, and through The spraying of conformal paint forms a 25-75um coating film on the PCB. The coating film provides excellent protection and coverage, thereby improving and extending the service life of the PCB and ensuring the safety ...
