Inner wall paint with temperature regulating and energy storage functions and preparation method thereof

Abstract

The invention belongs to the technical field of functional paint, and provides inner wall paint with temperature regulating and energy storage functions and a preparation method thereof. The method comprises the following steps of preparing a temperature regulating and energy storage filling material using paraffin adsorption kieselguhr particles as a core material and using nanometer heat conduction filling material containing polytetrafluoroethylene as bag materials; then, mixing the filling materials with acrylic ester emulsion, antifoaming agents, flatting agents, dispersing agents and pigments; preparing the inner wall paint with the temperature regulating and energy storage functions. Compared with a conventional method, the prepared inner wall paint has excellent temperature regulating and energy storage functions; the response time is short; the kieselguhr pores cannot be easily blocked; the paint cannot be easily pulverized; the paint durability is improved.

Description

technical field [0001] The invention belongs to the technical field of functional coatings, and provides an interior wall coating with the function of temperature regulation and energy storage and a preparation method thereof. Background technique [0002] During the use of buildings, a large amount of energy needs to be continuously consumed, accounting for about 30-40% of human energy consumption, and most of it is used for heating and air conditioning. Moreover, with the growth of population, the growth of high building energy consumption has become an inevitable trend, which will bring huge pressure on energy supply. At present, my country's new construction area is nearly 2 billion m 2 , more than 95% of which are still high-energy-consuming buildings. If no energy-saving measures are taken, 50% of the country's energy consumption will be in the construction field by 2020. Therefore, building energy-saving energy storage technology has become an important development ...

Problems solved by technology

However, there are disadvantages such as poor thermal conductivity and poor energy storage effect of phase change capsules.

[0007] To sum up, currently commonly used temperature-adjusting energy storage coatings generally have poor dispersion of phase change materials, easy agglomeration, and easy blockage of filler pores, resulting in structural damage. At the same time, they have high thermal resistance, poor thermal conductivity, and unsatisfactory energy storage effects. The use durability is not good, so it is of great significance to develop a kind of interior wall coating with the function of temperature regulation and energy storage
