Abstract

The invention relates to a waterborne reflective thermal insulation coating. The waterborne reflective thermal insulation coating comprises the following raw materials by weight: 1-5 parts of cellulose, 5-10 parts of a dispersing agent, 1-5 parts of a defoaming agent, 1-5 parts of a wetting agent, 1-4 parts of bactericide, 1-4 parts of pH regulator, 40-80 parts of titanium dioxide near infrared ray reflection powder, 100-200 parts of titanium dioxide, 60-90 parts of calcined kaolin, 60-90 parts of triple superphosphate, 30-70 parts of mica powder, 250-350 parts of silicone acrylic emulsion, 10-30 parts of a coalescing agent, 10-20 parts of ethylene glycol, 1-5 parts of a foam inhibitor, 2-6 parts of a levelling agent, 1-5 parts of a thickener, and 200-260 parts of water. The invention provides the brand new formula of the waterborne reflective thermal insulation coating, a preparation method of the waterborne reflective coating is also provided, compared with the traditional reflectivethermal insulation coating, the thermal insulation effect is better, and the resistance to dirty and the adhesiveness are greatly improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection coatings, in particular to a water-based heat-insulating coating. Background technique [0002] Coatings have a wide range of applications in the field of architectural technology, and their functions can be summarized into three aspects, namely, the protection of buildings, decoration and other specific functions. Heat-insulating coatings are coating products that are improved on the basis of conventional coating products to give them better heat-insulating properties. The heat-insulating coatings in the prior art generally use glass microspheres, ceramic microspheres or heat-insulating powder as reflective insulation. However, it is found that its thermal insulation performance still needs to be improved during use, and there are still the following defects: 1. Poor storage stability: glass microspheres or ceramic microspheres are easy to produce microspheres during the storage ...
