Abstract

The invention relates to the technical field of coatings, in particular to environment-friendly three-proofing lacquer. The three-proofing lacquer comprises the following components by mass: 18 to 24 parts of acrylic resin, 8 to 12 parts of triethylene tetramine, 40 to 50 parts of isopropyl alcohol, 10 to 15 parts of ethyl acetate, 1 to 4 parts of a titanate coupling agent, 6 to 12 parts of n-butyl acetate, 10 to 20 parts of rosin modified alkyd resin, 1 to 5 parts of a defoaming agent, 2 to 6 parts of a waterproof additive, and 1 to 3 parts of an electrostatic prevention additive. The environment-friendly three-proofing lacquer prepared according to the invention has the advantages that the proportion is reasonable; the surface properties are improved; the viscosity is reduced; due to the combined use of the titanate coupling agent, the rosin modified alkyd resin and the defoaming agent, the hardness and the glossiness of a lacquer film can be improved, and the lacquer film can be excellent in water resistance, heat resistance and adhesive force; the insulating capacity is improved; due to the addition of the nanometer penetration waterproof agent and the electrostatic prevention agent, the lacquer film can be easy to wet and high in sealing property, electric leakage can be prevented effectively, the insulating effect can be favorable, and the use is safe.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly three-proof paint. 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. [0003] 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 the occurrence of circuit boards. Fault. Conformal paint is a coating material with a special formula. The three-proof paint is coated on the surface of the circuit board to form a transparent protective film. The protective film can withstand humidity, s...
