Waterborne heat-insulating slurry and preparation method thereof, as well as waterborne heat-insulating glass coating and preparation method thereof

Abstract

The invention provides waterborne heat-insulating slurry and a preparation method thereof, as well as a waterborne heat-insulating glass coating and a preparation method thereof. The waterborne heat-insulating slurry is prepared by selecting nano-ATO and carbon nano-tubes as main heat-insulating materials, the specific optical performance of the nano-ATO is utilized, the long-wave part of an infrared region and an ultraviolet region have a high rejection rate, and a visible region has high transmittance; the carbon nano-tubes with specific carbon atomic arrangement structure have durable high heat-insulating efficiency and ultraviolet aging resistance under near-infrared and ultraviolet irradiation, so that irradiation reflection of the infrared region can be effective reinforced, the defects that the nano-ATO has insufficient partial heat insulating performance and insufficient ultraviolet aging resistance for the near-infrared short-wave part can be overcome. The waterborne heat-insulating glass coating prepared from the heat-insulating slurry and waterborne organic silicone modified acrylic resin can be used for solving the problems of insufficient transparency, poor heat-insulating performance and weak weather resistance of existing coating, and can be kept durable, stable and uniform.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based heat-insulating slurry and a preparation method thereof, and a water-based heat-insulating glass coating using the water-based heat-insulating slurry and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the improvement of people's living standards, large windows and glass curtain walls have been widely used in domestic buildings in recent years, which not only increases the decoration and lighting effects of buildings, but also increases the cooling capacity of buildings in summer and heating in winter. According to statistics, the energy consumption of buildings in my country accounts for 40% of the total energy consumption, and the energy lost through door and window glass is 46%. Therefore, in the process of building energy-saving design research, the heat insulation protection of various glasses has become ...
