Description
Technical Field
The invention relates to the technical field of three-proofing paint, in particular to UV photo-moisture curing three-proofing paint and a preparation method thereof.
Background
The three-proofing paint is a coating material with a special formula and can be widely applied to the protection of circuit boards of electronic and electric equipment. The three-proofing paint is coated on the surface of the circuit board to form a transparent protective film, and the protective film can protect the circuit board from being damaged in environments such as humidity, mould, salt fog, chemical corrosion, high dust, vibration and the like, so that the reliability of the circuit board is improved, and the safety coefficient of the whole electronic element is increased.
Classified from chemical components, three-proofing paints can be mainly divided into three major categories: organosilicon three-proofing paint, acrylic ester three-proofing paint and polyurethane three-proofing paint. The organosilicon three-proofing paint is extremely easy to adsorb sulfur dioxide, hydrogen sulfide and other sulfur-containing substances in the air, and forms a vulcanization phenomenon of welding spots, so that the circuit board is invalid. The three-proofing acrylic paint has the advantages of high curing speed and low cost, but has weak resistance to organic solvents, unsatisfactory dampproof, salt fog proof and mildew proof effects and poor thermal shock resistance. The polyurethane three-proofing paint has the advantages of quick drying, strong adhesive force, good impact resistance and electrical insulation performance, very good flexibility, wear resistance and chemical resistance, excellent comprehensive performance, better protection effect and suitability for corrosion protection of circuit boards. The polyurethane three-proofing paint used at present mainly uses organic solvent as diluent, and the solvent type polyurethane three-proofing paint has the following main problems: 1) Some solvents volatilize into the air, can generate irritation, and can induce occupational diseases after long-term contact; 2) Some solvents are heavy in pungent smell, so that the working environment is influenced, and the working efficiency is reduced; 3) Some solvents belong to toxic and harmful solvents, can pollute the environment, have stricter environmental protection policy requirements and face policy pressure; 4) Some solvents are flammable and explosive, and have great potential safety hazards in the production, transportation and storage processes.
Disclosure of Invention
(one) solving the technical problems
Aiming at the defects of the prior art, the invention provides the UV photo-moisture curing three-proofing paint and the preparation method thereof, which solve the problems that the three-proofing paint is stimulated to induce occupational diseases, affects the working environment and is toxic and harmful.
(II) technical scheme
In order to achieve the above purpose, the present invention provides the following technical solutions: the UV photo-moisture curing three-proofing paint comprises the following raw materials in parts by weight:
35% -70% of polyurethane acrylic ester, 20% -40% of acrylic ester isobornyl, 10% -30% of acrylic ester monomer, 0.5% -5% of auxiliary agent and 1% -10% of initiator.
A preparation method of UV photo-moisture curing three-proofing paint comprises the following steps:
s1, selecting raw materials of 35% -70% of polyurethane acrylic ester, 20% -40% of acrylic ester isoborneol, 10% -30% of acrylic ester monomer, 0.5% -5% of auxiliary agent and 1% -10% of initiator;
s2, mixing and stirring the raw materials in the S1 to obtain the three-proofing paint;
wherein the stirring temperature is 30-50 degrees, and the stirring time is 30 minutes.
Through stirring raw and other materials, consequently make the mixture more even between multiple raw and other materials, and then improve the subsequent result of use of three proofings lacquer.
S3, vacuum defoaming is carried out on the three-proofing paint obtained in the step S2;
through carrying out the vacuum to the three proofings lacquer and remove the bubble, consequently make three proofings lacquer more even in the spraying process, reduce the bubble and exist the damage and the unevenness phenomenon that treat the spraying work piece surface and lead to the fact, consequently improve three proofings lacquer subsequent result of use.
S4, polyurethane acrylic ester is composed of one or a mixture of more of ethyl acrylate, n-propyl acrylate, butyl acrylate, hydroxyethyl acrylate, hydroxypropyl acrylate, methyl methacrylate, butyl methacrylate, hexyl methacrylate, dodecyl methacrylate, glycidyl methacrylate, hydroxypropyl methacrylate, allyl methacrylate, ethoxypropyl methacrylate, acrylamide and vinyl acetate.
And in the production process of polyurethane acrylic ester, after materials are mixed, stirring is carried out on the materials and bubbles are eliminated, the stirring time is 1h, and the temperature is constant.
S5, acrylic ester isoborneol is formed by mixing one or more of acrylic substances, camphene, tricycloalkene, polymerization inhibitor and catalyst.
S6, the acrylic ester monomer is selected from one or more of tetrahydrofuran methacrylate, methyl methacrylate isobornyl, 2-phenoxyethyl acrylate, isocyanate formal acrylate, alkoxylated tetrahydrofuran acrylate, acrylic acid isobornyl, triethylene glycol dimethacrylate, 1, 4-butanediol dimethacrylate, diethylene glycol dimethacrylate, 1, 6-ethylene glycol diacrylate, isocyanate triacrylate and pentaerythritol tetraacrylate.
