Water-based interior wall thermal insulation nano coating

Abstract

The invention provides a water-based interior wall thermal insulation nano coating, belonging to the technical field of environment-friendly water-based building energy conservation coating. The coating comprises the following components by weight percentage: 20-40% of emulsion, 20-35% of pigment filler, 5-15% of thermal insulation function material, 0.1-1% of thickening agent, 0.5-2.5% of wetting and dispersing agent, 0.1-0.6% of defoaming agent, 0.4-2.5% of anti-creaming agent, and the balance water. Due to containing no organic matters with large volatility, the coating in the invention has little toxicity and is favor to environment protection. The adopted pigment filler in the invention is nano-level or superfine magnesium carbonate or magnesium silicate, thus greatly improving the surface area of the pigment, and increasing gaps among coating particles by a large margin, thereby enhancing the thermal separation property of the coating. The water-based interior wall thermal insulation nano coating provided in the invention has obvious radiative thermal insulation and separation type thermal insulation effects, and has simple preparation process and wide application.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly water-based energy-saving coatings for buildings, and in particular relates to a nanometer water-based thermal insulation coating for interior walls. Background technique [0002] The poor thermal insulation performance of buildings is the main factor of high energy consumption and heavy energy burden in summer. Thermal insulation coatings are more and more popular because of their advantages such as convenient use, good thermal insulation effect and economical feasibility. Most of the research on thermal insulation coatings focuses on the development of thermal insulation coatings for exterior walls, but not enough attention is paid to the research of thermal insulation coatings for interior walls. At present, foamed plastics, expanded perlite and hollow microspheres are used for thermal insulation in the interior wall thermal insulation coatings of most buildings. They use the gaps...
