Abstract
The invention discloses a flame-retardant protective coating for a bromocarbon acrylic acid printed circuit and a preparation method thereof. The coating comprises the following compositions by mass percentage: 5.0 to 10.0 percent of 2,4, 6-tribromophenyl acrylate, 13.0 to 18.0 percent of butyl methacrylate, 0.5 to 4.0 percent of methyl methacrylate, 2.0 to 4.0 percent of styrene, 0.5 to 2.0 percent of acrylic acid, 8.0 to 12.0 percent of butyl acrylate, 0 to 2.0 percent of 2-ethyl hexyl acrylate, 15.0 percent of dimethylbenzene, 44.6 percent of ethyl acetate, and 0.4 percent of evocating agennt. The flame-retardant protective coating realizes the polymerization of Br element by introducing the flame-retardant element Br into a styrene-acrylic resin, overcomes the disadvantage of short time limit of additive type flame-retardant coatings, has good flame-retardant property as well as high breakdown voltage resistance and electrical insulating property, and also has the characteristics of light color, good gloss and color retention, easy construction, and strong decorativeness of thermoplastic acrylic acid resin coatings at the same time.
Description
Technical field
The present invention relates to coating composition, specifically is a kind of flame-retardant protective coating for bromocarbon acrylic acid printed circuit.
Background technology
Thermoplastic acrylic paint have look shallow, protect that the light tint retention is good, the advantage of good weatherability, stable manufacturing process and easy construction, occupy important position in the high-decoration field of household electrical appliances, light industrial goods and instrument, development in recent years is rapid.And it is as the printed wiring protective cover, and good anti-electrical breakdown performance and electrical insulation capability must be arranged, and along with the raising of the fire-retardant requirement of electrical apparatus industry, people more and more pay close attention to the flame retardant properties of printed wiring protective cover.
Patent CN 1178237A with in bi-maleimide modified rubber be base-material, introduce fire retardant, behind organic solvent dissolution, add oxidation inhibitor, the fire-retardant sizing agent that coupling agent, resol and Resins, epoxy system are formed, the bonding of be used for polyimide, gathering fragrant fibrous paper film and aluminium foil etc.
Patent CN 1394923A is used for the bonding of multi-layer flexible printed electronic circuit layer and interlayer with the fire-retardant sizing agent of multicomponent methacrylate monomer, allyl group phosphoric acid ester, cross-linking monomer, reaction initiator, emulsifying agent, phosphorous filler and mineral filler composition.
It is protective cover that existing printed wiring protective cover all adopts thermoplastic acrylic, but its filmogen does not have flame retardant effect, only plays the effect of Lacquer finish protection, and the fire-retardant rank of electrical equipment is difficult to improve.Therefore work in this respect seems particularly important.
Summary of the invention
The purpose of this invention is to provide a kind of flame-retardant protective coating for bromocarbon acrylic acid printed circuit and preparation method thereof.
Flame-retardant protective coating for bromocarbon acrylic acid printed circuit of the present invention, by mass percentage, this coating is made up of following raw material:
