Abstract

The invention relates to the field of coating, and particularly discloses a phase-change water-based exterior wall paint capable of intelligently adjusting temperature and a preparation method thereof. The phase-change water-based exterior wall paint capable of intelligently adjusting the temperature comprises the following raw materials in percent by mass: 15-33% of deionized water, 0.2-0.6% of a thickening agent A, 0.1-0.3% of a wetting agent A, 0.1-0.3% of a wetting agent B, 0.3-0.8% of a dispersing agent, 0.4-0.6% of a defoaming agent, 1-2.5% of a film-forming auxiliary agent, 0.2-0.3% of a pH stabilizer, 1-2% of an antifreezing agent, 2.5-18% of titanium dioxide, 6-15 % of barite, 8-12% of mica powder, 23-35% of a modified polymer emulsion, 0.3-0.7% of a thickening agent B, 0.3-0.8% of a leveling agent, 0.2-0.5% of a bactericidal mildewcide and 10-20% of a microencapsulated phase change material. The phase-change water-based exterior wall paint capable of intelligently adjusting the temperature, provided by the invention, has the characteristics of excellent water resistance, acid and alkali resistance, scrub resistance and artificial aging resistance, efficient and stable heat storage and heat release, and energy conservation.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a phase-change exterior wall water paint for intelligent temperature regulation and a preparation method thereof. Background technique [0002] With the improvement of people's material level, people's requirements for the living environment are getting higher and higher, and the use of energy-consuming equipment such as air conditioners has risen sharply, which not only consumes a lot of energy, but also brings certain threats to the environment. Taking developing countries as an example, the increase in building energy consumption is extremely astonishing, exceeding 20% ​​of the total energy consumption in developed countries. 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 chang...
