Sand-in-water colorful paint with excellent early water resistance

Abstract

The invention discloses sand-in-water colorful paint with excellent early water resistance. A method comprises the steps of production of protective glue, production of base paint, production of a sand-in-water colorful paint continuous phase, production of colorful particles and production of the colorful paint. The early water resistance of the sand-in-water colorful paint can be effectively improved, and the problems that paint turns white and changes color due to weather change in practical construction can be well solved.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to an early water-resistant sand-in-water colorful coating. Background technique [0002] The heat-resistant sand-coated multi-color paint is a kind of architectural decorative paint, its decorative effect is similar to that of natural stone, it has the characteristics of light weight, environmental protection, and rich colors, and can be used for high-rise exterior wall decoration. When the sand-in-water multi-color paint is used for exterior wall decoration, the construction procedure is generally: a putty layer is applied on a flat and firm base → a sealing primer → a primer → two water-in-sand multi-color paint → 1-2 coats Finish paint, primer, colorful paint finish paint, when spraying, the interval between each coat should be at least 24 hours to ensure the dryness of the coating. After the finish paint is applied, the entire coating system should be painted within 7 days...

Problems solved by technology

When the sand-in-water multi-color paint is used for exterior wall decoration, the construction procedure is generally: a putty layer is applied on a flat and firm base → a sealing primer → a primer → two water-in-sand multi-color paint → 1-2 coats Finish paint, primer, colorful paint finish paint, when spraying, the interval between each coat should be at least 24 hours to ensure the dryness of the coating. After the finish paint is applied, the entire coating system should be painted within 7 days under standard conditions. In actual construction, it is difficult to ensure that the system can be dried for more than 7 days without encountering rainy weather. Since the water-in-sand multi-color paint contains hydrophilic additives such as cellulose and thickeners, it will be dry during this period. Rain will cause the water-in-sand colorful paint layer to turn white, and it is difficult to restore
