Problems solved by technology

At present, titanium dioxide or hollow microsphere materials are used for heat insulation coatings for exterior walls. Such exterior wall heat insulation coatings, such as patents CN102352160A and CN102702822A, have poor appearance and unsatisfactory reflection effects.
Patent CN102153919 mentions the preparation method of dark brown infrared reflective thermal insulation water-based color paste by using infrared reflective pigments and fillers. The color paste has poor moisture retention and stability

Abstract

The invention discloses a method for preparing heat-insulation pigment painting paste with high infrared reflectivity for buildings, and belongs to the field of chemical technologies for painting. The method includes compounding infrared reflection inorganic metal pigment color paste and aluminum paste with each other to obtain the heat-insulation pigment painting paste for the buildings. The heat-insulation pigment painting paste for the buildings can be added in emulsion paint for external walls, the emulsion paint can be coated on stone plates, and the total solar reflectivity and the infrared reflectivity of the stone plates can be obviously improved after the stone plates are naturally dried in the air. Compared with the prior art, the method for preparing the heat-insulation pigment painting paste for the buildings has the advantages that the heat-insulation pigment painting paste is high in infrared reflectivity, painting has diversified colors and is excellent in moisture retention and heat stability.

Description

Technical field: [0001] The invention belongs to the technical field of paint chemical industry, and in particular relates to a preparation method of high infrared reflectivity building heat-insulating paint color paste. Background technique: [0002] Infrared rays account for more than 50% of the energy of sunlight, especially the near-infrared band, which will increase the temperature in the room when it irradiates the roof and walls. In summer, air conditioners are used to lower the indoor temperature, which causes a lot of energy waste. Architectural thermal insulation coatings can effectively reflect the infrared rays in sunlight, keep the indoor temperature low, and achieve the effect of energy saving. In addition, building thermal insulation coatings can avoid the danger caused by the temperature rise of open-air chemical storage tanks. At present, heat insulation coatings for exterior walls use titanium dioxide or hollow microspheres for reflective heat insulation....
