A multi -function batch scraping single, dual -component heat insulation coating and preparation method

Abstract

The invention relates to a multifunctional scrapping type single-component thermal insulation coating, a multifunctional scrapping type bi-component thermal insulation coating and preparing methods of the multifunctional scrapping type single-component thermal insulation coating and the multifunctional scrapping type bi-component thermal insulation coating. The multifunctional scrapping type single-component thermal insulation coating is formed by main paint. The main paint is prepared from, by weight, 2-3% of anti-freezing agent, 1-1.5% of dispersing agent, 1-2% of wetting agent, 0.15-0.2% of pH regulator, 0.3-0.6% of defoaming agent, 30-35% of emulsion, 25-35% of thermal insulation material, 0.4-0.8% of lignocellulose, 0.2-0.5% of mildew preventive, 0.3-0.6% of antibacterial agent, 0.15-0.3% of preservative and 1-3% of film-forming additive, the balance being water. The multifunctional scrapping type bi-component thermal insulation coating is formed by mixing main paint and white cement according to the weight ratio of 8-12:1. The multifunctional scrapping type single-component thermal insulation coating and the multifunctional scrapping type bi-component thermal insulation coating which are prepared with the methods are extremely low in heat conductivity coefficient, high in solar emissivity, good in thermal insulation function, free of cracking in impasto and capable of bringing a strong sense of decoration.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a multifunctional batch-scraping type thermal insulation coating. Background technique [0002] Architectural thermal insulation coatings are one of the hotspots in architectural coatings research. In recent years, great progress has been made, and there are many related papers and patents. At present, the research on architectural thermal insulation coatings is mainly divided into two directions: one is architectural thermal insulation coatings, and most of them are thick coatings. In order to achieve the purpose of thermal insulation, the corresponding thermal insulation materials used are mostly sepiolite, expanded perlite, expanded vermiculite, etc. The color is complex and the decorative feeling is poor, so it is less used for topcoating; the second is architectural thermal insulation coatings, generally thin coatings, which can achieve the purpose of thermal insulatio...

AI Technical Summary

Problems solved by technology

At present, the research on building thermal insulation coatings is mainly divided into two directions: one is building thermal insulation coatings, mostly thick coatings, and the lower thermal conductivity of the coating and the thicker coating thickness are used to ensure the maximum coating In order to achieve the purpose of thermal insulation, the corresponding thermal insulation materials are mostly sepiolite, expanded perlite, expanded vermiculite, etc. with low thermal conductivity. Since the thermal insulation materials used are mostly colored materials, the color is dark, resulting in thermal insulation coatings The color is complex and the decorative feeling is poor, so it is rarely used for top coating; the second is building heat insulation coatings, generally thin coatings, which achieve the purpose of heat insulation by improving the reflectivity of the coating or heat radiation. Thermal materials are mostly hollow microspheres, far-infrared radiation ceramic powder, etc., but this kind of coating is easy to crack when thickly coated, so this type of heat-insulating coating is mostly used for exterior wall coating of buildings, especially reflective heat-insulating coatings can only be used under sunlight. better function
