Problems solved by technology

However, its raw material formula contains xylene as a reflux solvent during esterification, and xylene will remain in the resulting resin.
[0005] At present, the grinding resins on the market can only grind inorganic pigments or organic pigments, and their compatibility is limited. Most of them contain benzene solvents, which do not meet the requirements of green environmental protection, and have problems of poor color development and weather resistance, which cannot meet Coatings Market Demand

Abstract

The invention specifically relates to environmentally-friendly general resin for color paste and a preparation method thereof, belonging to the technical field of resin for paints. The environmentally-friendly general resin for color paste comprises, by weight, 11-22 parts of propylene glycol methyl ether acetate, 5-15 parts of butyl acetate, 8-15 parts of glycidyl versatate modified macromonomers, 4-6 parts of a functional complex, 10-20 parts of hydroxyethyl methacrylate, 10-25 parts of methyl methacrylate, 5-10 parts of butyl acrylate, 10-20 parts of N-butoxymethylacrylamide, 5-12 parts ofmethacrylic acid and 1.6-3.3 parts of di-tert-amyl peroxide. The environmentally-friendly general resin for color paste in the invention has good compatibility, can be used for grinding of inorganic pigments and organic pigments, and presents high dispersing efficiency, excellent color development performance and good weather resistance. In addition, the environmentally-friendly general resin forcolor paste does not contain any benzene solvent and thus has good environmental protection performance.

Description

technical field [0001] The invention belongs to the technical field of coating resins, and in particular relates to an environmental-friendly universal color paste resin and a preparation method thereof. Background technique [0002] In the paint industry, the traditional color paint production process is to add all the pigments in the formula to the grinding paint composed of grinding resin, wetting and dispersing agent, solvent, etc., pre-disperse and grind, and wait until the fineness is qualified. Then add certain ingredients (such as solvents, additives, resins, etc.) as needed to prepare the paint. In recent years, more and more paint manufacturers have adopted the so-called single-color paste method to produce colored paints. This type of process is to disperse a single pigment in the grinding resin in advance to make a color paste of the color of the pigment, and then mix the main film-forming substance, various color pastes, additives and solvents evenly according ...
