Energy-saving phase-change interior wall water-based paint and preparation method thereof

Abstract

The invention discloses an energy-saving phase-change interior wall water-based paint and a preparation method thereof, and belongs to the technical field of coatings. The energy-saving phase-change interior wall water-based paint comprises the following raw material components: deionized water, cellulose A, cellulose B, a dispersant, a wetting agent, a potassium silicate stabilizer, an antifoaming agent A, titanium dioxide, wollastonite, mica powder, diatomite, an antifoaming agent B, a potassium silicate solution, a modified polymer emulsion, a coalescing agent, a thickening agent A, a thickening agent B, a thickening agent C and a microcapsule phase change material. The energy-saving phase-change interior wall water-based paint prepared by the invention has good functions of leveling, decorating, and sealing base materials and the like based on the phase-change material heat storage and release technology; the energy-saving phase-change interior wall water-based paint has stable andefficient heat storage and release functions, endothermic reaction is induced when the wall surface temperature is above 25 DEG C, and exothermic reaction is induced when the wall surface temperatureis lower than 15 DEG C, the overall temperature of buildings is automatically adjusted, energy consumption is reduced, the applicability is high, and the paint is easy to apply and popularize.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an energy-saving phase-change interior wall water paint and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the concept of environmental protection is a requirement for the coatings industry after people attach great importance to ecological environment protection, and it is also the development direction of the coatings industry. Building energy efficiency has become an important part of energy security and sustainable development strategy, and it is one of the current active research directions. Phase change heat storage technology uses the latent heat of material phase change to scientifically store and utilize energy, which can not only solve and alleviate the mismatch between energy conversion and supply and demand in time, space, intensity and location, but also facilitate efficient use of energy and benefit energy savin...

Problems solved by technology

[0003] However, in the prior art, the phase change energy storage material is generally mixed directly with other components of the water-based paint and applied to the water-based paint. However, since the phase change energy storage material is in direct contact with other raw materials, the phase change material will be damaged. , Corrosion and the reaction of the surrounding environment and other issues, resulting in a decrease in the use efficiency of phase change materials, which will lead to poor temperature adjustment effects of the entire system

In addition, during use, due to temperature changes, such as too low temperature, during the phase change process, it is easy to cause phase separation of the paint, which not only affects the effect of the phase change energy storage of the paint, but also affects the service life of the paint , so it is limited in actual use
