[0037] Preparation of nano-ATO slurry:

[0038] Add powdered ATO and dispersant KH570 to water, and make nano-ATO slurry by ball milling at 3000r / min for 48 hours. Keep the system temperature at about 30°C, and then adjust the pH value of the system to 8. The effect of ball milling time on the pH value of the slurry system Such as figure 2 shown. The laser particle size analyzer is used to test the dispersed particle size and distribution of the slurry, the morphology of the particles is characterized by TEM, the stability of the slurry is studied by the centrifugal sedimentation method, and the thermal weight loss and infrared spectroscopy are used to prove whether KH570 has been bonded.

[0039] Preparation of matrix resin:

[0040]WPU can be synthesized according to the following steps: Add polyester diol (Mn1000) and DMPA (where -COOH accounts for about 1.5% of the molecular chain mass ratio) into a three-necked bottle, vacuum dehydrate at 120-130°C for 2 hours, and add...

Abstract

The invention belongs to the technical field of nano coatings, and particularly relates to a water-based nano heat insulating coating used for glass. The water-based nano heat insulating self-cleaning coating used for glass consists of the following components by weight: 45-55 portions of high molecular resin, 5-15 portions of nano ATO slurry, 0.1-1 portion of crosslinking agent, 0.1-0.8 portion of ultraviolet absorber and 5-10 portions of ethanol. The invention aims at overcoming the disadvantages in the prior art, and provides a heat insulating coating used for glass which has excellent heat insulating performance and transparency, weather resistance, simple and feasible production process, convenient construction and low production cost and a preparation method thereof.

Description

technical field [0001] The invention belongs to the technical field of nano-coatings, in particular to water-based heat-insulating nano-coatings for glass. Background technique [0002] Among all kinds of energy consumption, building heating and air conditioning energy consumption occupies a considerable proportion. Doors and windows, as transparent and openable envelopes in house construction, are the weakest part of winter heat preservation and summer heat insulation. [0003] At present, the main application of energy-saving glass is Low-E glass, also known as low-emissivity coated glass, which has good energy-saving effect and is widely used, but its equipment is expensive, energy consumption is high, and it needs to be made into double-layer insulating glass to maintain its energy-saving effect. . [0004] There are only two options for energy-saving renovation of glass in existing buildings: one is to remove the original glass and replace it with energy-saving glass,...
