Abstract

The invention provides a high-strength water-soluble powder coating, which is composed of the following components, and the content of each component is expressed in parts by weight: 30-40 parts of epoxy quaternary ammonium sulfonate film-forming polymer, epoxy silsesquioxane 10-15 parts, 10-15 parts of bentonite, 1-3 parts of rare earth polishing powder, 2-6 parts of defoamer, 1-3 parts of dispersant, 2-5 parts of film-forming aid. The invention also discloses a preparation method of the high-strength water-soluble powder coating. Compared with the common solvent-based coatings in the prior art, the high-strength water-soluble powder coating disclosed by the present invention does not contain organic solvents, has better safety, is more environmentally friendly, and has excellent adhesion, film-forming properties, lubricity, and gelation properties. Excellent performance, chelating property, dispersibility, anti-friction property, strength and thickening property, and more significant decorative effect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength water-soluble powder coating and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy and the improvement of people's living standards, the decoration of buildings has become more and more luxurious, and the decoration materials used are also changing with each passing day. These decoration materials bring people visual beauty and comfort. It has brought serious harm to the environment on which human beings depend for survival and their own physical and mental health. In recent years, due to the deterioration of the ecological environment and the enhancement of people's awareness of environmental protection, environmental protection has attracted more and more attention from the world. Various countries have formulated relevant laws and regulations to strictly limit the emission of volatile or...
