Waterborne multicolor coating with freeze-thaw resistance, basic paint for waterborne multicolor coating and method for preparing basic paint

Abstract

The invention provides waterborne multicolor coating with freeze-thaw resistance, basic paint for the waterborne multicolor coating and a method for preparing the basic paint. The basic paint for thewaterborne multicolor coating with the freeze-thaw resistance comprises, by weight, 10-12 parts of hydroxyethyl cellulose aqueous solution, 4-8 parts of dispersing agents, 2-6 parts of defoaming agents, 5-6 parts of coalescing agents, 10-12 parts of antifreezing agents, 0.1-3 parts of pH (potential of hydrogen) regulators, 8-12 parts of titanium dioxide, 80-90 parts of kaolin, 300-350 parts of pure acrylic emulsion, 1-5 parts of sterilizing preservatives, 2-5 parts of thickeners, 0-2 parts of leveling agents and 530-550 parts of deionized water. The waterborne multicolor coating, the basic paint and the method have the advantages that appropriate auxiliaries and emulsion are screened to prepare the basic paint, accordingly, the freeze-thaw stability of products can be guaranteed, and undesirable phenomena such as increase of broken points of multicolor particles, soft color points, frozen color points, post-thickening and the like can be prevented.

Description

technical field [0001] The invention relates to the technical field of coatings, and specifically discloses a base paint for a freeze-thaw-resistant water-based colorful paint, a freeze-thaw-resistant water-based colorful paint and a preparation method thereof. Background technique [0002] Liquid stone multi-color paint is rich in color, easy to construct, and can get the decorative effect of rock in one spraying, and the price is economical and reasonable, and it is convenient for later renovation and renewal. It has gradually become a trend in the application of interior and exterior walls of architectural decoration projects. After recent After several years of technical precipitation, the degree of simulation of colorful coatings, production technology and room temperature storage (heat storage) have all been greatly improved. However, low-temperature storage, especially in the northwestern region where the temperature difference between day and night is large, as the t...

AI Technical Summary

Problems solved by technology

However, low-temperature storage, especially in the northwestern region where the temperature difference between day and night is large, as the temperature gradually decreases, the molecular movement of the protective glue will become weaker, and the package strength will decrease, which will lead to more broken spots of colorful particles during production, softer colored spots and frozen colored spots. Bad, post-thickening and other bad phenomena
