Abstract

The invention discloses environment-friendly circuit board epoxy primer which is characterized by being prepared from the following raw materials in parts by weight: 35-40 parts of amino resin, 30-35 parts of E-44 epoxy resin, 1.0-1.5 parts of catechol, 2-3 parts of triacetin, 1-2 parts of silane coupling agent KH-550, 1-2 parts of glycidyl methacrylate, 4-5 parts of polymethacrylate, 3-4 parts of zinc oxide, 1-2 parts of magnesium oxide, 1-2 parts of nano silicon dioxide, 3-4 parts of N-2-(aminoethyl)-3-aminopropyl trimethoxy silane, 4-5 parts of styrene, 10-12 parts of ethyl acetate and 3-4 parts of dispersing aid. According to the invention, the dispersing aid improves the optical property, the primer can be uniformly dispersed, and the stability of the primer can be maintained; the heavy metal content of the antirust primer disclosed by the invention can meet requirements of related laws and regulations; and the primer is environment-friendly and harmless to human health, and has excellent corrosion resistance, rust resistance and saline-alkaline tolerance.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an environment-friendly circuit board epoxy primer 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 purpose of the present invention is to provide a kind of environment-friendly ...
