Reflective thermal insulation coating

Abstract

The invention relates to a reflective heat insulation coating. The coating is prepared from the following components in parts by mass: 10-20 parts of heat-reflecting and heat-insulating powder, 30-35parts of styrene-acrylic emulsion, 15-20 parts of rutile-type titanium dioxide, 10-15 parts of calcium carbonate, 2.5-5 parts of mica powder, 0.8-1.5 parts of an antifreeze agent, 1.5-2 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, 0.3-0.5 parts of a thickener, 0.8-1.3 parts of a dispersing agent, 0.15-0.3 parts of a defoaming agent, 0.2-0.3 parts of a fungicide, 0.3-0.5 parts of a preservative and 13-25 parts of water. The reflective heat insulation coating can achieve better heat insulation effect, and the problems about color matching, construction, suspension, thickening, filmplumpness and the like can be solved.

Description

technical field [0001] The invention relates to the field of heat-insulating coatings, and more specifically, the invention relates to a reflective heat-insulating coating. Background technique [0002] With the rapid development of the construction industry, the energy saving and environmental protection of buildings are becoming more and more important. Therefore, the issue of building energy conservation has been paid more and more attention. At present, my country's building energy consumption accounts for about 27% of the country's total energy, ranking first in all types of energy consumption in the country. In addition, the energy consumption of heating and air conditioning accounts for 55% of the total energy consumption of buildings, and it is still growing at a rate of 1% per year. Therefore, the research and development of building thermal insulation coatings has significant economic, environmental and social benefits. The use of coatings with heat-insulating f...

AI Technical Summary

Problems solved by technology

[0003] 1. In the case of the same addition amount, the coating made of glass hollow microspheres and ceramic microspheres requires high coating thickness and is easy to crack and has poor heat insulation performance;

[0004] 2. Unstable storage performance: products made of glass hollow microspheres or ceramic microspheres are prone to defects such as viscosity increase and floating during storage;

[0005] 3. Poor workability: due to the obvious post-thickening, it can only be diluted with water to achieve the scraping effect during construction. It is difficult to control the viscosity of the amount of water added, which has a great impact on construction and heat insulation effects;

[0006] 4. The price is relatively expensive: the high-quality glass hollow microspheres or ceramic microspheres selected for the preparation of reflective heat insulation coatings are mainly imported, and the price is generally high, which has a great impact on the production cost of the coating;

[0007] 5. Monotonous color: It is difficult to color the heat-insulating coating prepared with glass hollow microspheres or ceramic microspheres, mainly white;

[0008] 6. The heat-insulating coating made of hollow glass microspheres or ceramic microspheres has unevenness in the paint film after construction, and the paint film is not full, which cannot achieve the desired effect
