Problems solved by technology

[0009] 1) Without light, it will also cause premature curing due to reaction with moisture in the air, resulting in increased viscosity, which will affect normal use and reduce service life;
[0010] 2) Sensitive to moisture, resulting in increased viscosity during construction and storage, increasing construction difficulty;
[0012] 4) The volume shrinkage rate is large, the adhesion is poor, and the insulation performance and anti-corrosion performance of the paint film in the shadow area are reduced after curing

Embodiment approach

[0064] As an embodiment of the present invention, the photoinitiator is 2-hydroxy-2-methyl-1-phenyl-1-propanone.

[0065] Leveling aid: Leveling aid is a commonly used coating additive, which can promote the formation of a flat, smooth and uniform coating film during the drying and film-forming process of the coating. A class of substances that can effectively reduce the surface tension of coating fluids and improve their leveling and uniformity. It can improve the permeability of the coating solution, reduce the possibility of spots and marks when brushing, increase the coverage, and make the film formation uniform and natural. Mainly surfactants, organic solvents, etc. There are many types of leveling agents, and the types of leveling agents used in different coatings are also different.

[0066] The leveling aid in the present invention is selected from silicone-based leveling aids.

[0067] The preparation method of silicone-based leveling aid described in the present i...

Abstract

The invention provides an efficient and environment-friendly UV-dark curing conformal coating. The conformal coating is prepared from the following raw materials: 30 to 70 parts of acrylic resin; 30 to 70 parts of a reactive diluent; 1 to 10 parts of a photoinitiator; 0.1 to 5 parts of a leveling agent; 0.1 to 8 parts of a defoaming agent; 0.1 to 10 parts of a wetting agent; 0.1 to 3 parts of a flame retardant.

Description

technical field [0001] The invention relates to the technical field of printed circuit board protection, in particular to a circuit board anti-corrosion, high-efficiency and environment-friendly UV-dark curing three-proof paint. Background technique [0002] Conformal paint is widely used for anti-corrosion protection of electronic and electrical equipment circuit boards, such as smart home appliances, automotive electronics, power supply / frequency conversion, intelligent industrial control, military ships, outdoor precision equipment, etc. The three-proof paint is coated on the surface of the circuit board, and a dense protective film is formed after curing to protect the circuit board from the corrosion of the external environment (moisture, mold, salt spray, high dust, vibration, corrosive gas, etc.), and improve the product quality. Reliability, increase the use of safety factor. [0003] The existing UV-moisture curing method is based on light curing and the reaction w...
