Sunlight heat-reflecting thermal-insulating water-in-water colorful environment-friendly coating and production method thereof

Abstract

The invention discloses a sunlight heat-reflecting thermal-insulating water-in-water colorful environment-friendly coating and a production method thereof. The coating is formed through three stages of a colloid solution, a granulation base coating and a latex finished coating, wherein the colloid solution is specifically composed of the following components in parts by weight: 90-100 parts of tap water, 2 parts of cross-linking stabilizer, and 7-8 parts of protection glue powder; the granulation base coating is composed of the following components in parts by weight: 400-450 parts of tap water, 6-10 parts of wetting dispersant, 4-9 parts of defoamer, 5-8 parts of film-forming agent, 10-15 parts of propylene glycol, 80-100 parts of heat insulation powder, 5-10 parts of cellulose, 13-16 parts of auxiliaries, 100-150 parts of colloid solution, 250-300 parts of elastic polymer emulsion, and 40-50 parts of infrared reflecting pigment; the latex finished coating is composed of the following components in parts by weight: 200-220 parts of elastic polymer emulsion, 250-290 parts of tap water, 10-14 parts of film-forming agent, 8-10 parts of propylene glycol, 0.5-1 part of defoamer, 480-510 parts of granulated basic coating and 3-5 parts of auxiliaries, wherein the granulated basic coating is a coating obtained by granulating the granulation base coating. The sunlight heat-reflecting thermal-insulating water-in-water colorful environment-friendly coating is capable of realizing heat reflection on sunlight and insulating heat, and has diversified colors.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, and particularly discloses a water-in-water multicolor coating for solar heat reflection and heat insulation and a production method thereof. Background technique [0002] With the improvement of people's living standards, the upsurge of interior decoration has quietly risen, and people have higher and higher requirements for the decorative effect of coatings. With its bold conception, multi-color paint breaks the traditional single-color and flat coating decoration effect, and creates a colorful and three-dimensional decorative surface, which is favored by consumers. At present, the oil-in-water type multi-color pattern paint is more popular in the market. Its coating film is plump, bright in color, gorgeous in pattern and perfect in decorative effect. However, the dispersed phase of the paint is oily, which has hidden dangers of safety and environmental pollution. [0003] The ...
