Abstract

The invention provides a phase change energy storage temperature-adjusting internal wall coating and a preparing method thereof. The phase change energy storage temperature-adjusting internal wall coating comprises, by mass, 30%-50% of emulsion, 0.5%-1.5% of dispersing agents, 0.5%-2% of antifreezing agents, 1%-3% of coalescing agents, 1%-2% of thickening agents, 0.5%-1% of defoaming agents, 5%-15% of titanium dioxide, 5%-10% of functional padding, 15%-30% of composite phase change materials and the balance water. According to the phase change energy storage temperature-adjusting internal wall coating and the preparing method, the attapulgite-based paraffin composite phase change materials serve as temperature-control base materials, the obtained phase change coating has good energy storage performance, cheap in price and excellent in weather resistance, energy consumption is saved, the indoor comfort is improved, the phase change coating is not limited by the territory and weather in use due to the adjustable phase change temperature, the application field of the phase change coating is broadened, and the coating has the good economic benefits and environment benefits and wide application prospects.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an interior wall coating for regulating indoor temperature and a preparation method thereof. technical background [0002] The increasing shortage of energy makes improving energy efficiency and developing and utilizing renewable energy a worldwide problem to be solved. With the rapid development of the construction industry and the improvement of people's quality of life, building energy consumption has accounted for about 1 / 3 of the total energy consumption of the whole society, and it is showing a trend of continuous increase. At present, interior wall coatings are developing in the direction of high efficiency, thin-layer heat insulation, and waterproof integration. As an important part of building energy conservation, heat insulation coatings have become a research hotspot in the industry. [0003] Phase change material (PCM) is a thermally functional material that can absorb or rel...
