Water-borne heat insulation powder coating

Abstract

A water-borne heat insulation powder coating uses nano-level complex titanic acid ester powder as a heat insulation material, uses complex tricalcium silicate and tetra calcium aluminoferrite as a barrier material of the nano-level titanic acid ester, and uses mixture of polypropylene monomer-polyvinyl alcohol (1: 1) as a complexing agent. The coating has the following advantages: the coating has excellent heat insulation and heat preservation effects, and the heat insulation effect is at the temperature of 10 to 18 DEG C; the use is very convenient, and brush coating or spray coating can be carried out by adding tap water till required viscosity; and the coating is safe and environmentally protected without any noxious heavy metal and solvent; the coating has weathering resistance and enhancing effect for cement of building wall body; the coating has the same water resistance and weathering resistance as cement, and has anti-seepage ability for rainy water; the coating can be used as building Tempojel; and the coating can be brush-coated on the surfaces of various materials such as cement, steel plate, glass, and the like, and has rust preventing effect on steel plates when being applied to steel plates.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based heat-insulating powder coating. Background technique [0002] At present, building energy saving has become the top priority of the current energy saving work. Various places have developed various interior and exterior wall heat insulation coatings. The Central Development and Reform Commission also implemented relevant standards on November 1, 2007. According to its standards, its heat insulation performance, aging resistance The performance is not as good as that of similar foreign products, and the weather resistance of similar products in China, whether it is oil-based exterior wall paint or water-based exterior wall paint, does not exceed 3-5 years, and the heat insulation materials used are nothing more than ordinary vermiculite and sepiolite. Glass beads are also used, but they cannot solve the "frame effect" brought about by them. At the same time, due to ...

[0002] At present, building energy saving has become the top priority of the current energy saving work. Various places have developed various interior and exterior wall heat insulation coatings. The Central Development and Reform Commission also implemented relevant standards on November 1, 2007. According to its standards, its heat insulation performance, aging resistance The performance is not as good as that of similar foreign products, and the weather resistance of similar products in China, whether it is oil-based exterior wall paint or water-based exterior wall paint, does not exceed 3-5 years, and the heat insulation materials used are nothing more than ordinary vermiculite and sepiolite. Glass beads are also used, but they cannot solve the "frame effect" brought about by them. At the same time, due to the limited thickness of ordinary heat-insulating coatings, their heat-insulating effect is great under several hours of sunlight. discount
