Problems solved by technology

However, the direct introduction of lightweight aggregate or reflective heat-insulating pigments into the real stone paint will make the surface of the paint film dull and affect the decorative properties of the real stone paint itself.
In addition, there are many pores in the coating film of real stone paint, and simply adding reflective heat-insulating pigments and hollow glass microspheres cannot completely fill these pores, so that a large amount of heat will still be conducted into the paint film.

Abstract

The invention belongs to the field of functional architectural coatings, and in particular relates to double-coated reflective heat-insulation stone-like paint and a preparation method thereof. The double-coated reflective heat-insulation stone-like paint comprises the following components: 10-12 parts of deionized water, 12-16 parts of a water-based polymer emulsion, 0.05-0.1 part of an antifoaming agent, 0.4-0.6 part of a film-forming auxiliary agent, 0.2-0.3 part of a bactericidal preservative, 0.1-0.2 part of a dispersing agent, 0.2-0.3 part of bentonite, 0.3-0.5 part of an antifreezing agent, 0.1-0.2 part of a thickening agent, 0.05-0.1 part of a pH regulating agent, and 65-75 parts of double-coated quartz sand. The double-coated reflective heat-insulation stone-like paint provided bythe invention has the characteristics of high stability, high weather resistance and diversified colors, so that the stone-like paint truly realizes perfect combination of decorative performance andheat insulation performance.

Description

technical field [0001] The invention belongs to the field of functional architectural coatings, in particular to a double-coated reflective heat-insulating real stone paint and a preparation method thereof. Background technique [0002] In the field of exterior wall architectural coatings, the real stone paint made of natural colored sand and synthetic resin emulsion has the decoration of imitating natural stone, as well as certain flexibility and weather resistance, and because of its light weight, safety, and low cost, it has become popular in recent years. It has been widely used in the field of construction. As the demand for exterior wall architectural coatings with energy-saving and heat-insulating functions continues to increase, how to introduce energy-saving effects into real stone paint has become a subject of intense research. [0003] In order to realize the energy-saving and heat-insulating function of existing real stone paints on the market, a certain amount ...
