Abstract

The invention discloses a circuit board flame-retardant anti-rusting paint. The circuit board flame-retardant anti-rusting paint is characterized by being prepared from the following raw materials in parts by weight: 55-60 parts of E-12 epoxy resin, 1-2 parts of zinc powder, 0.8-1.2 parts of tributyl phosphate, 2-3 parts of aminopropyl triethoxysilane. 20-24 parts of amino resin, 2-3 parts of polyvinyl alcohol, 1-2 parts of aluminum hydroxide, 8-12 parts of diatomite, 30-35 parts of polyesteracrylate, 1-2 parts of triethanolamine, 3-4 parts of mica powder, 2-3 parts of polyisobutene, 14-18 parts of ethyl acetate and 3-4 parts of dispersing aid. According to the circuit board flame-retardant anti-rusting paint disclosed by the invention, the dispersing aid can be used for improving the optical performance, so that the paint is uniformly dispersed and the stability of the paint is kept. The circuit board flame-retardant anti-rusting paint disclosed by the invention has extremely strong corrosion resistance and rusting resistance for metals, is high-temperature-resistant and flame-retardant, can be used for overcoming the defects of the conventional epoxy paint, and is simple in preparation process and especially suitable for being used as a protective paint of metals.

Description

Technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a flame-retardant anti-rust paint for circuit boards and a preparation method thereof. Background technique [0002] The names of the circuit boards are: circuit boards, PCB boards, aluminum substrates, high frequency boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances. Circuit boards work in a variety of different environments, many of which are harsh, such as sunlight, high temperature, and corrosion, and need to be painted on the circuit board for protection. The existing paint cannot meet this need. Summary of the invention [0003] The purpose of the present invention is to provide a high-temperature-resistant, flam...
