Abstract

A light gray dry-film conductive primer is mainly composed of 40-60 parts by weight of thermoplastic acrylic resin and 1-5 parts by weight of graphene. The provided light gray dry-film conductive primer is prepared by mixing surface modified graphene and thermoplastic acrylic resin and adding a solvent and rutile titanium white. The primer has the lightness (L value) more than 40 and the resistivity less than 0.3 M omega*cm. The primer has no influence on the color of a finishing coat, can help the finishing coat and varnish to realize electrostatic coating, and helps to improve the paint utilization rate and save material cost.

Description

technical field [0001] The invention relates to a paint with electrical properties, in particular to a light gray dry film conductive primer, which is suitable for plastic substrates such as ABS / PC / HIPS, so that the plastic substrate can be electrostatically coated. Background technique [0002] Conductive coating is a special functional coating developed rapidly along with modern science and technology, and has a development history of about half a century. In 1948, the United States published a patent for making conductive adhesive from silver and epoxy resin, which was the earliest disclosed conductive paint. my country also began to study and apply conductive coatings in the 1950s. In recent years, conductive coatings have been applied in various military and civilian industrial fields such as electronics, electrical appliances, aviation, chemical industry, and printing. Correspondingly, the theoretical research on conductive coatings has also developed rapidly, and ha...
