Abstract

The invention relates to a nanometer heat-insulating glass film and a manufacturing method thereof. The components of the film comprise a nano high polymer latex, nano powder dispersion liquid and assistants, and the manufacturing method comprises the following steps: selecting the nano high polymer latex; adopting ultrasonic dispersion and grinding technology to make nano powder into nano dispersion liquid; and then adding proper assistants to compound the nano high polymer latex and the nano dispersion liquid. The components of the film all have water solubility, and the aqueous one-component technology reduces the cost of the product. The film has the characteristics of environment-friendly and safe production and simple and easy-to-use construction, and has the property same as an oily product.

Description

technical field [0001] The invention relates to heat-insulating glass, in particular to a coating film of heat-insulating glass and a manufacturing method thereof. Background technique [0002] The new national building energy conservation standard stipulates that the energy saving of new buildings must reach 50%. At present, the energy consumption of building materials in my country accounts for 40% of the total energy consumption of buildings, and the energy lost through doors and windows is 50%. The area of ​​modern architectural glass used is increasing, and some even the entire outer wall is glass, the building is beautiful, but the energy consumption it brings is really amazing. In these glass places such as modern buildings and automobiles, how to use the visible light of the sun without turning on the electric lights, and at the same time isolate the infrared rays that increase the temperature, and use less air conditioners has become a market demand. [0003] How t...
