Abstract

The invention discloses glass heat isolation water-based paint and a preparation method thereof. The glass heat isolation water-based paint comprises a raw material body, and further comprises graphene, a first additive and a second additive, wherein the graphene accounts for 0.01 to 5 percent of the raw material body by mass; and the total amount of the first additive and the second additive accounts for 0.1 to 7 percent of the raw material body by mass. According to the glass heat isolation water-based paint and the preparation method thereof, the intensity of the glass heat isolation water-based paint is improved by adding of the graphene; by the use of the high heat conduction function of the graphene, the shortcoming that the heat accumulation temperature on the surface of glass coated with the existing heat absorption type glass heat isolation paint is high is overcome; furthermore, the friction resistance of the water-based paint, the bonding strength with a base material and the impact resistance are obviously improved; and the paint has obvious hydrophobic self-cleaning and heat isolation functions, can meet the environment-friendly development trend and the requirement, and has a wide application prospect in the field of heat preservation and isolation of building window glass and automobile glass.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based glass insulating coating and a preparation method thereof. Background technique [0002] Since 2004, graphene has become one of the research hotspots in the field of materials science. Graphene is actually a single atomic layer of graphite, which has a unique two-dimensional structure and excellent mechanical, thermodynamic, optical and electrical properties. [0003] Graphene is currently the thinnest but hardest nanomaterial in the world. It is almost completely transparent, absorbing only 2.3% of light, and its thermal conductivity is as high as 5300W / m·k, which is higher than that of carbon nanotubes and diamonds. Graphene is a new material with a single-layer sheet structure composed of carbon atoms. It has the characteristics of high strength, large specific surface area, high chemical reactivity, and high filling. [0004] Conventional water-based coatings for glass...
