Problems solved by technology

[0005] (1) Due to the large amount of solvent used, the environmental protection is extremely poor, which is detrimental to the environment and the health of construction personnel;
[0006] (2) The storage stability of the coating is poor, and the weather resistance is poor at the same time, so it is only suitable for interior decoration;
[0007] (3) The construction method of special spraying is required, so there are limitations in construction
[0009] The colorful paints described in the above-mentioned patents do not use or rarely use solvents, so the disadvantages of raw water/oil-based colorful paints are greatly improved in terms of environ

Abstract

The invention discloses a preparation method and the construction process of a waterborne marble-imitated multicolor paint, in particular to a compounding technology and the construction process of the water-in-water type multicolor external wall paint. The paint consists of a disperse phase and a disperse medium, wherein the waterborne multicolor dispersoid containing water-soluble colloid is taken as the disperse phase and the water is taken as the disperse medium, namely the multicolor dispersoid is uniformly dispersed in the water-dispersed medium containing the film-forming substance. The wall paint has excellent wall decoration and protection performance and high performance-to-price ratio; and as the coating is thin and light and has elasticity and stain resistance, the paint can be applicable to the high-rise external walls and the external heat-preservation coating decoration, thus solving the problem that the self-weight is large in the practical application process of the marbles, the wall bricks and the glass curtain walls. In the invention, the wall paint solves the construction localization that the special spraying gun is only used for the waterborne multicolor paint, the normal spraying gun for building can be used, therefore, the construction is convenient and is easy for operation, and the wall paint has wider application prospect.

Description

Technical field: [0001] The invention relates to a production method and a construction process of a water-based imitation marble colorful paint, in particular to a highly decorative water-in-water type colorful paint. The production method and construction process belong to the technical field of chemical industry. Background technique: [0002] With people's further understanding of the environmental protection, decorative and protective functions of paint, the traditional exterior wall latex paint can no longer meet the requirements of consumers because of its monotonous decorative style. At the same time, in recent years, the country's energy-saving requirements have been further improved, and external thermal insulation coatings for exterior walls have received strong support, while the decorative materials used for external thermal insulation have also shown a trend of diversification. Due to the monotonous decorative style of traditional exterior wall paint, marble an...
