Method for preparing transparent and heat insulating water ultraviolet curing coating

Abstract

The invention relates to a method for preparing an aqueous ultraviolet photo-cured coating with transparence and heat insulation and belongs to the technical field of environment-friendly energy-saving coating. The coating consists of a modified heat insulating nanometer serous fluid for emulsifying and compounding an aqueous UV prepolymer, a light evocating agent, a coating additive and the like. The modified heat insulating nanometer serous fluid carries out emulsification and compounding on the aqueous UV prepolymer so as to obviously improve the dispersion and stability of the coating, wherein a heat insulation nanometer powder body is an oxide consisting of tin, stibium, zinc, copper and aluminum so that the coating has high transparency and heat insulation and low radiation; the coating uses water as a solvent, fully meets the requirement of environmental protection, adopts a spraying or knifing mode, utilizes ultraviolet radiation for curing and film forming, can realize the automatic coating of production lines and has convenient construction; and a coating film has the characteristics of good weather resistance, high rigidity, strong adhesive force and the like.

Description

technical field

[0001] The invention relates to a preparation method of a transparent heat-insulating water-based ultraviolet (UV) cured coating, which belongs to the technical field of environmental protection and energy-saving coatings. Background technique

[0002] Today, in the face of the increasingly tense situation of energy and resources in the world, my country vigorously advocates the construction of a sustainable development and conservation-oriented society, and the promotion and application of energy-saving coatings is of great significance. Among all kinds of energy consumption, building heating and air-conditioning consume a considerable proportion, and the heat lost through doors and windows accounts for about 60% of the entire building's heating and air-conditioning energy consumption. In recent years, people have adopted various methods for heat insulation and energy saving treatment, such as filmed glass, solar control coated glass and low-emissivity glass...
