Abstract

The invention discloses environment-friendly paint for construction and a preparation method thereof. The environment-friendly paint comprises, by weight, 50-80 parts of fatty acid modified high-viscosity short-oil alkyd resin, 35-45 parts of polyurethane resin, 15-23 parts of hydroxypropyl methacrylate, 12-36 parts of sodium salicylate, and the like. The environment-friendly paint has the advantages that the paint is free of odor, difficult to volatilize and difficult to foam and deteriorate; added nano materials can inhibit and kill bacteria and effectively prevent the paint from generating pungent smell during storage, and the paint is environmentally friendly and does not cause environment pollution and damage human bodies.

Description

technical field [0001] The invention relates to a building environmental protection paint and a preparation method thereof. Background technique [0002] Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. Coatings are generally composed of four parts: film-forming substances, fillers (pigments and fillers), solvents, and additives. Depending on performance requirements, the ingredients may vary slightly. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class of multifunctional engineering materials and an important industry in the chemical industry. Paint is an indispensable material in the decoration process. Due to the improvement of living standards and the increasing calls for environmental protection, people have higher and higher requirements for decorative paints. However, mos...
