Low-gloss high-reflectivity thermal-insulation powder paint

Abstract

The invention relates to a powder paint, particularly a low-gloss high-reflectivity thermal-insulation powder paint. The powder paint is prepared by adding nano zirconium dioxide, a curing accelerator, a cold pigment, a filler and assistants into high-acid-value super-weather-resistance carboxyl-terminated matting polyester used as a base material. The low-gloss high-reflectivity thermal-insulation powder paint only has 3-7 units of gloss, has the ultraviolet long-wave/medium-wave and infrared reflectivity of higher than 85%, can effectively obstruct 85-90% of the sunlight long/short-wave heat source, has greatly lower the short-wave absorptivity and low heat conductivity coefficient (not more than 0.0563 W/m.K), has favorable weather resistance and thermal insulation property, and can low lower the thermal-insulation function due to the pollution on the coated film surface. The low-gloss high-reflectivity thermal-insulation powder paint has light gloss, high reflectivity, low heat conductivity coefficient, low heat storage coefficient and other heat engineering properties, and is an energy-saving environment-friendly paint which has the advantages of zero VOC (volatile organic compound) emission, high adhesiveness, long service life, thermal insulation, moisture resistance, flame retardancy, electric insulation, fire resistance and no peculiar smell.

Description

technical field [0001] The invention relates to a powder coating, in particular to a low-light and high-reflection thermal insulation powder coating. Background technique [0002] General building external insulation mostly uses polyurethane foam, extruded polystyrene XPS and molded polystyrene EPS and other materials, but the construction cost is high, the operation is complicated, and it is greatly affected by the construction method, which is prone to thermal bridge phenomenon and is harmful to sunlight. The reflective function of the reflector is often controlled by environmental pollution, and gradually decreases with the serious pollution. Contents of the invention [0003] The object of the present invention is to provide a low-gloss high-reflection thermal insulation powder coating, which has the characteristics of stable coating gloss, good environmental performance and good outdoor durability. [0004] The low-light and high-reflection thermal insulation powder ...
