Environment-friendly composite coating and preparation method thereof

Abstract

The invention discloses an environment-friendly composite coating and a preparation method thereof, and belongs to the technical field of coating preparation. The coating is prepared from the following raw materials in percentage by weight: 1 to 3 percent of water emulsion-based synthetic resin, 2 to 6 percent of a dispersing agent, 8 to 15 percent of water-based high gloss varnish, 2 to 6 percentof polyphenyl ether resin powder, 3 to 9 percent of talcum powder, 3 to 6 percent of barium sulphate, 1 to 3 percent of lime powder, 1 to 3 percent of sodium benzoate, 2 to 4 percent of ethylene glycol, 1 to 3 percent of a flame retardant and the balance of water. The environment-friendly composite coating is clear in preparation principle and scientific in components; compared with the conventional composite material, the composite coating prepared by the preparation method is more environment-friendly; the defects, such as needle holes, bubbles, cracks and peeling, of the composite coatingare effectively filled; the using requirement of environment friendliness of the composite coating is met; and the defects and the disadvantages of the composite material are filled.

Description

technical field [0001] The invention belongs to the technical field of paint preparation, and relates to a composite paint and a preparation method thereof, in particular to an environment-friendly composite paint and a preparation method thereof. Background technique [0002] The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. Since the founding of New China 60 years ago, along with the development of various industries in the national economy, the coating industry as a supporting tool has gradually developed from a very inconspicuous small industry to an indispensable and important industry in various fields of the national economy. After several generations of hard work and pioneering...

Problems solved by technology

[0004] The present invention aims at the fact that the existing composite coatings are not environmentally friendly, which affects the health of personnel; the composite coating itself has pinholes, foaming, whitening, bottom bite, oil separation, non-drying or slow drying, loss of gloss, sagging, brushing, etc. mark, orange peel, cracking, peeling, peeling, bulging, peeling and rough paint film, etc., an environmentally friendly composite coating and its preparation method are proposed, which can solve the above-mentioned deficiencies in the prior art and can meet the needs of composite coatings. Environmentally friendly use needs to make up for the defects and deficiencies of the composite material itself
