Thermal insulation slurry and novel aqueous carbon nanotube composite thermal insulation coating using thermal insulation slurry and preparation method thereof

Abstract

The invention provides a thermal insulation slurry and a novel aqueous carbon nanotube composite thermal insulation coating using the thermal insulation slurry and a preparation method thereof. Carbon nanotube powder in the thermal insulation slurry uses a polyethylene glycol-adsorbed porous-wall carbon nanotube as a core material, titanium dioxide is coated over the core material, and as an important component of the thermal insulation slurry, the carbon nanotube powder enables the thermal insulation slurry to have integrated multiple thermal insulation modes. The novel aqueous carbon nanotube composite thermal insulation coating uses a carbon nanotube material of a special structure in the thermal insulation slurry as a thermal insulation material and a nanometer aqueous fluoro-silicone emulsion as a film forming substance, so the prepared novel aqueous carbon nanotube composite thermal insulation coating has protruding thermal insulation performance and good stability and application properties. The preparation method for the novel aqueous carbon nanotube composite thermal insulation coating has the advantages of simple and easily available construction equipment and simple technological operation; and the coating prepared by using the method has protruding thermal insulation performance and good stability and application properties.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a thermal insulation slurry, a novel water-based carbon nanotube composite thermal insulation coating using the thermal insulation slurry and a preparation method thereof. Background technique [0002] With the rapid development of the economy, China has become the second largest energy consumer in the world. In recent years, problems such as energy shortage and environmental pollution will restrict the rapid development of the economy. Energy conservation and environmental protection have become more and more important in the sustainable development of my country's economy. more important. [0003] Building energy consumption accounts for about 30% of the energy consumption of the whole society. At present, the vast majority of buildings in China are high-energy buildings, and a large number of high-energy buildings are added every year. To achieve the carbon emissions promised in the nat...

AI Technical Summary

Problems solved by technology

[0004] At present, the thermal insulation coatings sold in the market mainly include reflective thermal insulation coatings, barrier thermal insulation coatings and radiation thermal insulation coatings. The coating is easy to age and degrade, has poor stain resistance and crack resistance, resulting in low heat insulation effect and heat insulation durability of the coating, and limited energy saving effect on buildings
