Abstract

The invention discloses antirust paint for a circuit board. The antirust paint is characterized by being prepared from the following raw materials in parts by weight: 30-35 parts of alkyd resin, 40-45 parts of E-12 epoxy resin, 12-15 parts of amino resin, 10-14 parts of xylene, 2-3 parts of anilino-methyl-triethoxysilane, 1-2 parts of an antioxidant 1010, 12-14 parts of sepiolite, 2-3 parts of polyglycerol fatty acid ester, 1-2 parts of phenyl trichlorosilane, 1-2 parts of zirconium oxide, 1-2 parts of titanium dioxide, 1-2 parts of sodium hydrogen carbonate, 2-3 parts of tung oil, 10-12 parts of ethyl acetate and 3-4 parts of a dispersing auxiliary. The dispersing auxiliary improves the optical property, so that the paint is uniformly dispersed, and the stability of the paint is maintained. The paint disclosed by the invention is firm in interlayer bonding, good in overbaking performance, good in decorativeness, low in cost and high in hardness, and has good decorative effect and wear resistance.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a circuit board antirust paint and a preparation method thereof. Background technique [0002] The names of circuit boards are: circuit board, PCB board, aluminum substrate, high frequency board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. Because the circuit board works in various environments, many of which are harsh, such as light, high temperature, and corrosion, it is necessary to coat the circuit board with paint for protection, and the existing paint cannot meet this requirement. Contents of the invention [0003] The object of the present invention is to provide a kind of circuit board antirust paint and preparati...
