Problems solved by technology

However, they are either water-based paints or oil-based paints that do not use UV curing technology. The curing time is long. If the oil-based system (paint) also needs to consume more solvents, it will pollute the environment.

Abstract

The invention discloses an ultraviolet curing nano transparent heat-insulation composite coating belonging to the field of ultraviolet curing coatings and containing the following substances in percentage by weight: 30-75 percent of oilopolymer, 0.01-15 percent of photosensitive curing agent and 10-55 percent of activated monomer, as well as 0.1-15 percent of stannic oxide. The transparent heat-insulation coating can be prepared in 1 minute under ultraviolet irradiation at room temperature, and the curing speed is high and the cost is low. The coating has selectivity to a solar spectrum, and a coating film which is about 5-70 micrometers is formed on the material surface. When the coating is used for glass, the visible light transmissivity of the glass is still higher than 75 percent, and the infrared thermal screening factor is higher than 70 percent, thereby not only keeping the transparency of the original glass, but also effectively isolating the infrared thermal radiation of sunlight. The coating has good ageing resistance, contamination resistance, anti-static performance, anti-dazzle performance, radiation protection, quick curing, environmental protection and the like.

Description

technical field [0001] The invention relates to an ultraviolet light curing coating, in particular to an ultraviolet light curing nano transparent heat-insulating composite coating. Background technique [0002] Nano-transparent heat-insulating composite coating is a high-tech energy-saving coating developed in recent years. The coating utilizes the excellent infrared shielding properties of nanomaterials and selects an excellent coating system to make the nano-transparent heat-insulating composite coating have the characteristics of strong adhesion, transparency, infrared shielding, heat insulation, and environmental protection. According to measurements, the coating coated with this paint can make the temperature difference between the front and back sides of the measured object reach 9 degrees Celsius, and the energy-saving performance is very superior. It is of great significance to apply the coating to glass to prevent the transmission of infrared rays and effectively ...
