Problems solved by technology

[0003] Now the coatings on the market are developing rapidly. With the call of the country for energy conservation and emission reduction, various environmental protection and energy-saving functional coatings have emerged, such as coatings with thermal insulation functions, coatings with heat insulation functions, and coatings with anti-mildew functions. However, coatings capable of regulating temperature have not yet appeared. The main reason is that the existing temperature-regulating phase-change materials are simply mixed with coating components, and there is a phenomenon of phase-change material leakage, which cannot effectively exert its phase-change potential.

Abstract

The invention provides thermal control paint and a preparation method thereof, belonging to the building material filed. The thermal control paint which is novel functional paint is manufactured by adding organic and inorganic composite phase-change materials in common paint or functional paint, wherein the organic and inorganic composite phase-change materials are obtained by compounding expanded perlite, attapulgite, zeolite or sepiolite and paraffin or octadecane. The thermal control paint not only has the prior functions and the effect of beautifying the environment, but also has the phase-change thermal control function, can automatically adjust the indoor temperature, and improve the indoor comfort degree; in addition, the thermal control paint is the environment-friendly paint which is energy-saving and pollution-free.

Description

Technical field: [0001] The invention relates to the field of building energy-saving materials, in particular to coatings with a temperature-adjusting function. Background technique: [0002] In recent years, the energy shortage problem is one of the problems that the country urgently needs to solve. In the national "Eleventh Five-Year" scientific and technological research project, we attach great importance to the research work of energy-saving materials. Temperature-regulating phase change materials can absorb or release a large amount of latent heat during the phase change process, and can be widely used in the fields of heat storage and temperature control. In the past 20 years, they have developed rapidly in European and American countries. Phase change energy storage composite material is a kind of thermal functional composite material, which can store energy in its carrier in the form of phase change latent heat, and realize energy conversion between different space...
