Abstract

The invention relates to a coating with infrared radiating effect, composed of infrared radiating powder and polyacrylic resin emulsion and other routine fillings and resistant; the infrared radiating powder is an alpha- cordierite structural powder obtained by making high-temperature burning or further mixing with stearic acid 14-28 weight shares and acrylic acid 3.5-7 weight shares and then drying after grinding the mixture of magnesium chloride 7.8-13 weight shares, zinc oxide 1.5-10.5 weight shares, alumina 33-34.5 weight shares, and quartz sand 48.7-51 weight shares. It is mainly used for building inner wall, and because of being added with Zn-doped cordierite system, its normal infrared radiation ratio in 2.5-25 mum waveband at normal temperature is not less than 0.90, able to effectively realize mildew resistant and bacteriostatic.

Description

technical field [0001] The invention relates to a coating with infrared radiation effect and a preparation method thereof. Background technique [0002] Water-based paint is a fast-growing architectural coating material, which has the advantages of anti-pollution, convenient application, fast film formation, and firm coating. It has now become the main interior wall paint variety. Since water-based coatings use water as a solvent, compared with solvent-based coatings, water-based coatings have more prominent anti-mildew and anti-bacterial problems. Mold and bacteria growth in water-based paint during storage will reduce the quality of the paint. After application, mold and bacteria growth in the film layer will cause the coating to age, stain the appearance, and even crack and peel off, causing the paint to lose its original protection. and decorative functions. [0003] At present, the method of adding various antifungal agents and antibacterial agents is usually used to ...
