Problems solved by technology

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

Abstract

The invention relates to an ultraviolet curing nano transparent heat-insulating composite coating. The ultraviolet curing nano transparent heat-insulating composite coating mainly comprises the following substances in percentage by weight: 30 to 75 percent of oligomer, 0.01 to 15 percent of photoinitiator, 10 to 55 percent of activated monomer, 0.1 to 15 percent of tin stibium oxide and 0.01 to 10 percent of nano material. The ultraviolet curing nano transparent heat-insulating composite coating can be prepared into a transparent heat-insulating coating within one minute through ultraviolet irradiation at normal temperature, so the curing speed is high and the cost is low. The coating has selectivity on solar spectrum and forms a coating film of about 2 to 7 mu m on the surface of a material. When the coating is applied to glass, visible light transmissivity of the glass is still more than 75 percent and the infrared heat shielding rate is more than 70 percent, so the coating maintains the transparency of the original glass, can effectively isolate infrared heat radiation of sunlight, and has the advantages of excellent aging resistance, stain resistance, self cleaning, static resistance, glare resistance, radiation resistance, high curing speed, environmental friendliness and the like.

Description

technical field [0001] The invention relates to a heat-insulating composite coating, in particular to a nanometer transparent heat-insulating composite coating cured by ultraviolet light. 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 performance of nanomaterials, and selects an excellent coating system, so that the prepared nano-transparent heat-insulating composite coating has 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 reduce...
