Problems solved by technology

However, the high temperature resistance of acrylate conformal paint is limited. Generally, it can only withstand high temperature of about 130°C. It has water and oil repellency, resulting in poor water resistance, oil resistance and self-cleaning performance of the coating film
In addition, ester solvents, alcohol solvents and solvent oil solvents (such as patent CN102732120A) commonly used in its preparation are flammable, and their vapor and air can form explosive mixtures, which can cause combustion and explosion when exposed to open flames and high heat. Violent reaction will occur, strong irritation to human body, low volatilization rate, slow construction progress

Embodiment 1

[0056] In a 500mL four-neck flask equipped with a reflux condenser, a thermometer, and nitrogen replacement, add 70.00g perfluorohexylethyl methacrylate, 15.00g octadecyl acrylate, 10.00g styrene, 5.00g hydroxyethyl (methyl base) acrylate, 1.00 g lauroyl peroxide initiator and 233.00 g nonafluorobutyl methyl ether solvent. After replacing the nitrogen, the oil bath was heated to 70°C and reacted for 20 hours. After the reaction was completed, a product with a solid content of 30% was obtained. Dilute the product with a solid content of 30% to 0.1% with nonafluorobutyl methyl ether diluent, and the diluted treatment solution is the three-proof electronic coating agent product, which can be used to directly treat the treated object.

Abstract

The invention discloses a novel oil-resistant, water-resistant and antifouling electron coating agent, which comprises, by mass, 0.1-10 parts of a fluorine-containing polymer and 90-99.9 parts of an organic solvent, wherein the fluorine-containing polymer contains a forming unit based on a fluorine-containing monomer (A), a forming unit based on a monomer (B), and a forming unit based on a cross-linking monomer (C), and the organic solvent is hydrofluoroether. According to the present invention, the electron coating agent has the advantages of excellent high-temperature resistance, excellent water resistance, excellent oil resistance and excellent antifouling performance through the fluorine-containing polymer, has the advantages of rapid drying and environment protection through the hydrofluoroether solvent, and is particularly suitable for the treatment of printing circuit boards (PCBs), electrical equipment, semiconductors, sensors, transducers, hybrid circuits and the like.

Description

technical field [0001] The invention belongs to the technical field of three-proof paint, in particular to a three-proof electronic coating agent, in particular to a three-proof electronic coating applied to printed circuit boards (PCBs), electrical equipment, semiconductors, sensors, transducers and hybrid circuits. coating agent. Background technique [0002] As electronic products gradually turn to miniaturization, integration, and multi-function, the electronic assembly industry is also developing at a high speed, and the requirements for the safety performance and appearance of assembled products are also getting higher and higher. After the electronic components are assembled, the circuit board may be in different environments during use, such as moisture, smog, chemical corrosion, high dust, vibration, etc., which will cause problems such as mildew and corrosion on the circuit board, resulting in circuit board error occured. Conformal paint is a coating material wit...
