[0004] Chinese invention patent application CN 104151979 A discloses a water-in-water reflective heat-insulating colorful coating, which can realize the reflective heat-insulating effect by adding 2-30% of the total weight of reflective heat-insulating powder, and the reflective heat-insulating powder is rutile type titanium dioxide powder Body, expensive, not conducive to the mass use of the product
[0005] Chinese invention patent application CN 104804601 A discloses a high-performance heat-insulating and heat-preserving multi-color coating. Hollow microspheres with a total weight of 10-15% are added to the dispersed phase base color paint to make colored dot particles with reflective heat insulation effect, while The coverage of colored dot particles on the surface is only 30%-80%, which is not enough to cover the entire wall, resulting in a decrease in the reflective heat insulation effect and affecting product performance

Embodiment 3

[0132] Embodiment 3 performance test

[0133] In the above-mentioned embodiment 1 and embodiment 2, after spraying, the color dot particles on the surface of the board are randomly distributed and are in a relatively uniform state. Various colors of colored dot particles decorate the surface of the board, making the surface of the board present the surface texture of natural granite. According to the color and proportion of different color point particles, different natural stones can be imitated. Due to the inclusion of hollow glass microspheres, the surface of the coating has a sandy feel, making the paint film closer to the texture of natural stone.

[0134] According to the standards of "HGT 4343-2012 Waterborne Colorful Architectural Coatings" and "JG / T 235-2008 Architectural Reflective and Heat-Insulating Coatings", Example 1 and Example 2 are tested, and the results are as follows:

Abstract

The invention relates to a reflective insulation colorful coating and a preparation method thereof. The colorful coating comprises the following components in percentage by weight: 10-30% of protective sol, 30-50% of colorful disperse-phase base paint and 20-50% of continuous-phase varnish, wherein the colorful disperse-phase base paint and the continuous-phase varnish both contain glass beads. In the invention, by taking synthetic emulsion as a basis and without depending on the addition of natural color sand, a stone-like effect can be obtained, and reproducibility is realized; and in the colorful coating prepared by the preparation method provided by the invention, the whole colorful coating has a reflective insulation function, realizes a good insulation effect and improves the energy saving effect.

Description

technical field [0001] The invention relates to an exterior wall paint, in particular to a reflective heat-insulating colorful paint and a preparation method thereof. Background technique [0002] At present, the imitation stone paint for exterior walls mainly includes real stone paint and colorful paint, and colorful paint is more realistic with its unique pattern simulation effect. Real stone paint is blended from natural colored sand, and the natural colored sand mine is increasingly depleted, and the prospect of real stone paint is worrying. Colorful paint is based on synthetic emulsion, does not rely on colored sand, and is sustainable. It will be the pillar product of imitation stone paint in the future. [0003] Reflective heat-insulating coating is an important technology for reducing energy consumption of building exterior walls. General reflective heat-insulating coatings are not very applicable to civil engineering due to their single color and poor decoration. ...
