Problems solved by technology

However, the current water-in-water multi-color coatings generally have the problems of poor initial water whitening resistance, particle strength, aging resistance, and corrosion resistance. Every time it rains, after being washed by rain, the surface of the paint film will turn white and turn white. It is not resistant to scratching, loosening or even peeling off, which greatly affects the appearance of the building; at the same time, it also has problems such as poor stability, easy thickening, particle bleeding, etc., and these problems are related to the formulation system of water-in-water multicolor coating The design itself is directly related to

Abstract

The invention provides a water white resistant particle crosslinking type water-in-water multicolor paint which is a water-based paint prepared by mixing a dispersing phase, a protecting adhesive aqueous solution and a continuous phase, wherein a crosslinking agent is a combination body of water-based isocyanate and hydrazine hydrate, or water-based isocyanate and adipic dihydrazide, or water-based isocyanate, hydrazine hydrate and adipic dihydrazide; a neutralizer is one or two of diethanol amine and triethanolamine. According to the water white resistant particle crosslinking type water-in-water multicolor paint provided by the invention, by the use of the neutralizer containing functionality hydroxyl in the dispersing phase and the continuous phase, the application of the hydroxyl at the grafted end of a neutralizing reaction emulsion molecular chain and the application of the hydroxyl in the neutralizer and isocyanato in the crosslinking agent, the isocyanato in the crosslinking agent and amino acid react with each other to generate polyurethane and polyurea, so that the dispersing phase and continuous phase meshed crosslinking density is increased, the molecular structures of polyurethane and polyurea materials are introduced, and a three-dimensional meshed structure crosslinking technology and high water resistance, toughness, weather resistance and strength of polyurethane or polyurea are used.

Description

technical field [0001] The invention relates to the field of coatings, and more specifically relates to a water-in-water multicolored coating with cross-linked water-resistant particles. Background technique [0002] Water-in-water multi-color paint is a new type of environmentally friendly water-based architectural paint prepared by applying innovative colloid technology and a new color concept. Different from the production technology of ordinary latex paint, the production technology of water-in-water multi-color paint includes design and preparation. The design includes pattern design and paint formula design; pattern design can realize the imitation of patterns and colors of natural granite, marble, etc., completely breaking through the traditional concept of color palette of paint, and introducing photography and painting to The effect of color processing can match the creative theme of decorative buildings and fully express the effect of decorative art. [0003] The ...
