Intelligent temperature control all-band-shielding nanometer transparent thermal insulation coating material and preparation process thereof

Abstract

The present invention discloses an intelligent temperature control all-band-shielding nanometer transparent thermal insulation coating material and a preparation process thereof, and belongs to a new functional nanometer material. The coating material contains, by weight, 35-80% of an aqueous acrylic acid resin, 0-20% of an aqueous amino resin, 10-30% of a nanometer ATO dispersion, 1-10% of a nanometer VO2 dispersion, 1-10% of a nanometer LaB6 dispersion, 1-15% of a nanometer WO3 dispersion, 0.05-1% of a leveling agent, 0.05-1% of an anti-foaming agent, and 5-20% of deionized water. According to the present invention, the average transmittance of the coating film in a visible light range is more than 85%, the transmittance at 380-400 nm is 0%, the transmittance at 800-1000 nm is 1%, and the transmittance at 1000-2000 nm is 2%; the thermal insulation effect is significant; compared with the blank glass, the thermal insulation property of the coating material has the following characteristic that: the temperature in the test box is reduced by 16-18 DEG C in an average manner through the glass coated with the composite nanometer transparent thermal insulation coating material; and the hardness of the coating film achieve 6H level, the adhesion achieves 0 level, and the transparency and the weather resistance are good.

Description

technical field [0001] The invention belongs to functional nanometer new materials, and in particular relates to a transparent heat-insulating coating which can be coated on various glass, plastic, metal and cement surfaces and a preparation process thereof. Background technique [0002] At present, large-area glass windows and glass curtain walls are widely used in the construction industry, and the poor heat insulation effect of glass will undoubtedly increase the load on air conditioners and cause a great waste of electric energy. Similar problems exist in vehicles, trains, and airplanes. The problem is how to solve the problem of blocking infrared light, far infrared light, ultraviolet light and heat radiation on the premise of passing through most of the visible light without affecting lighting, so as to reduce the energy consumption of air conditioning or heating devices and achieve energy saving Purpose. Most transparent heat-insulating coatings in the prior art use ...

AI Technical Summary

Problems solved by technology

The defect is that the coating film formed by the coating has poor light transmission performance, and the average transmittance in the visible light range is about 70%, which makes the lighting not very ideal; the hardness of the coating film is generally about 4H, which is low and cannot meet some requirements. In addition, compared with the thermal insulation performance of blank glass, the glass coated with composite nano-transparent thermal insulation coating detects that the temperature in the test box drops by 10 ° C to 13 ° C on average, and the thermal insulation effect is not good. ideal
