Abstract

The invention provides water-based industrial coating functional color paste and a preparation method thereof. The color paste comprises the following components in percentages by mass: 5-10 parts bymass of general resin, 30-70 parts by mass of toner and 4-6 parts by mass of a functional pigment, wherein the general resin is an acrylic resin containing reactive functional group hydroxyl and carboxyl; and the functional pigment is a water-based antirust pigment. The water-based industrial coating functional color paste disclosed by the invention has the advantages of high crosslinking density,water resistance and salt fog resistance in addition to color mixing and decoration performance.

Description

technical field [0001] The invention generally relates to the field of coatings, and in particular, relates to a water-based industrial coating functional color paste and a preparation method thereof. Background technique [0002] With the implementation of national environmental protection laws and regulations, environmental protection policies are becoming more and more stringent. Along with chemical companies are increasingly strict environmental protection controls. The coatings industry is taking advantage of this opportunity to develop, and water-based industrial coatings will be increasingly used and developed. [0003] As an auxiliary product color paste for industrial coatings, it also needs research and application. At present, the color pastes on the market include Klein, Shiming color paste, Chromaflo and other manufacturers. Although they have many years of production experience, although these color pastes have good color development, they are not very effectiv...
