Problems solved by technology

[0004] However, with the maturity of colorful coating technology, the stability of products is getting better and better, and the market promotion and use are getting stronger and stronger. Some problems in actual application and construction are also becoming more prominent. After the construction is completed, except In addition to the acquaintance of marble, the requirements for water and weather resistance of the outside world are getting higher and higher. At present, there is no paint that has both elongation, water resistance and weather resistance as the main material of colorful coatings to solve the problem of water whitening resistance.

Abstract

The invention relates to an exterior wall water-whitening-resistant colorful environment-friendly paint and a preparation method thereof. The paint comprises the components of, by weight, 25-40 parts of resin synthetic emulsion, 10-20 parts of powders, 4-8 parts of auxiliary agents, and 35-50 parts of water. According to the formula, all water is first added into a stirring kettle, and stirring is carried out with a speed of 300-600r/m; under continuous stirring, the first three among the auxiliary agents are sequentially added into the stirring kettle, and the mixture is well mixed by stirring; the powders are sequentially added into the stirring kettle according to the order in the formula; the stirring speed is adjusted to 1200-1600r/m, and stirring is carried out for 45-60min; after high-speed dispersion, the stirring speed is reduced to a low speed of 500-600r/m; all the resin synthetic emulsion is added into the stirring kettle; when the resin synthetic emulsion is well mixed, the rest part of the auxiliary agents are added; and a thickening agent is added under slow stirring, until a needed viscosity is reached. Compared with prior arts, the method provided by the invention has the advantages of low cost and simple process, and the product has the advantages of good elasticity, good weatherability and the like.

Description

technical field [0001] The invention relates to a base paint, in particular to a waterproof white and colorful environmental protection paint for exterior walls and a preparation method thereof. Background technique [0002] Colorful paint is composed of continuous phase or dispersion medium and dispersed phase. The continuous phase has low concentration and low viscosity; the dispersed phase has high concentration and high viscosity and contains colored pigments. Under the action of stirring, the dispersed phases of different colors are respectively dispersed into the continuous phase to form fine particles or droplets visible to the naked eye, and then mixed. It is also possible to disperse coloring base materials of different colors into the medium at one time to form multicolored coatings. According to the nature of the two phases. Colorful coatings can be divided into four categories: oil-in-water type, water-in-oil type, oil-in-oil type and water-in-water type. The ...
