Elastic self-cleaning reflective thermal-insulating coating

Abstract

The invention specifically discloses an elastic self-cleaning reflective thermal-insulating coating which comprises the following ingredients, by weight, 10-25% of water, 2-4% of an antifreezing agent, 1-5% of a thickening agent, 0.5-3% of a wetting agent, 0.5-2% of a dispersant, 0.3-4% of an antifoaming agent, 0.5-2% of a multifunctional additive, 0.5-3% of a bactericide, 5-20% of titanium dioxide, 10-20% of phthalocyanine pigment, 1-3% of a coalescing agent, 0.5-3% of a dry film mildew-inhibitor, 0-2% of a self-cleaning auxiliary agent, 30-50% of an elastic emulsion, 5-25% of hollow glass microspheres and 0-6% of hollow ceramic powder. In comparison with the prior art, the coating provided by the invention has good anticorrosion, mildew-resistant, moistureproof, waterproof, fine crack-resistant and antifouling effects. In addition, through high-efficiency reflective thermal insulation, thermal energy absorption by the wall is minimized, indoor temperature is reduced, air-conditioning energy consumption is decreased, energy conservation is realized, and reflective thermal insulation problem of houses is solved.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to an elastic self-cleaning reflective heat-insulating coating. Background technique [0002] As the temperature of the outer surface of the building exposed to the sun for a long time continues to rise, the outer surface of the building is cement, concrete, ceramic tile, metal, insulation brick and other building materials. The temperature of the outer surface of the building material can reach 40-50 ℃. The temperature can reach heights of 60°C. Under the high temperature of the outer surface of such a building, the temperature in the living room, workshop, etc. will inevitably rise, which will have a great impact on the safety of normal human living, material storage, and equipment, and even cause great safety hazards such as explosions. and energy waste. [0003] In order to lower the temperature and reduce the heat radiation of the sun, especially by increasing the reflection ...

AI Technical Summary

Problems solved by technology

However, traditional reflective heat insulation materials have disadvantages such as poor stain resistance, difficult control of the production process, long-term storage, and changes in heat reflective heat insulation performance with time and environmental changes, making it difficult to meet the durability of energy conservation and environmental protection.
