Abstract

The invention relates to the field of the coatings and in particular relates to an ultraviolet curable antifouling flame-retardant coating for a plastic circuit board. The ultraviolet curable antifouling flame-retardant coating for the plastic circuit board, namely an ultraviolet curable antibacterial coating for a metal building material, is characterized by being prepared from the following raw materials in percentage by weight: 30%-45% of mixed UV resin of aliphatic polyurethane diacrylate and bisphenol A epoxy diacrylate, 3%-5% of graphitized carbon nanofibers, 5%-12% of an initiator, 1%-3% of surface auxiliaries, 5%-10% of a cosolvent, 10%-20% of a reactive diluent, 1%-2% of a nano-silver antimicrobial agent and 10-30% of an inert solvent. The ultraviolet curable antifouling flame-retardant coating for the plastic circuit board has the antifouling and flame-retardant capability without affecting the intrinsic performance indexes of the coating.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a UV-cured coating used for plastic circuit boards that can resist pollution and be flame-retardant. Background technique [0002] Since the advent of UV-curable coatings, it has the characteristics of 5E, namely Efficient, Enabling, Economical, Energy Saying, and Environmental-friendly. In the prior art, UV-curable coatings have been widely used in fields closely related to life to beautify and protect objects. [0003] Plastic circuit boards are another type of thermoplastic engineering plastic circuit boards compared to the traditional thermosetting epoxy resin glass cloth fibers that are currently mainstream and used in large quantities in the electronics industry. The traditional printed circuit board is made by die-casting thermosetting resin and glass fiber into the base material, and then bonding conductive copper foil on the base material. However, the process of removing coppe...
