Reflective heat-insulation paint, and preparation method thereof

Abstract

The invention discloses a reflective heat-insulation paint. The reflective heat-insulation paint comprises, by weight, 25 to 35% of an emulsion, 0.5 to 0.6% of a film forming auxiliary agent, 3 to 5%of cellulose, 0.1 to 45% of a filling material, 0.1 to 0.2% of ceramic bead, 0.1 to 3% of an auxiliary agent, 0.01 to 0.06% of a multifunctional auxiliary agent, and the balance water. The invention also discloses a preparation method of the reflective heat-insulation paint. The reflective heat-insulation paint is excellent in weatherability, possesses heat insulation and reflection functions, water resistance, rust resistance, and mildew resistance, and can be used for metal iron-sheet tiles, building exterior walls, and cement roofing.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a reflective heat-insulating coating and a preparation method thereof. Background technique [0002] Building energy consumption accounts for 30% to 40% of human energy consumption. The area of ​​newly built houses in my country exceeds the sum of the built areas of all developed countries every year. Therefore, improving the thermal insulation of buildings is conducive to saving energy, reducing consumption, and improving the quality of buildings. Use function. With the implementation of the national building energy conservation and environmental protection industry policy, the energy saving and consumption reduction of buildings is particularly important. In recent years, due to the development of external wall thermal insulation technology, the thermal insulation coating of building walls has gradually changed from internal walls to external walls. Among them, the reflective...

AI Technical Summary

Problems solved by technology

The coating material has two effects of heat insulation and barrier, but the weather resistance, waterproof and antirust performance are not good

[0004] To sum up, the current traditional reflective heat insulation coatings have disadvantages such as increased wall load, high cost, poor decoration, poor reflective heat insulation effect, unstable performance, and difficult to control the production process. In addition, it is difficult to achieve waterproofing when used on metal substrates. , anti-rust purposes, can not meet the energy-saving environmental protection, durable, extensive use needs
