Abstract

The present invention discloses a transparent thermal insulation coating material system for a glass substrate. The coating material system is a double layer coating material system formed by a separately-prepared primary coating and a separately-prepared surface coating, wherein the surface coating is coated on the primary coating, the primary coating comprises the following components, by mass, 0.05-3 parts of a silicane coupling agent or a titanate coupling agent, 0.2-5 parts of a hydrolysis catalyst, and 95-99 parts of a solvent, and the surface coating comprises the following components, by mass, 50-80 parts of a light curable resin, 5-35 parts of an active diluent, 1-8 parts of a photoinitiator, 5-35 parts of an antimony tin oxide nanometer thermal insulation powder slurry or an indium tin oxide nanometer thermal insulation powder slurry, 100-140 parts of an inert diluent, and 0.01-0.15 part of a leveling agent. With the coating material system, a film can be formed through a conventional film forming method, and the film layer can be cured within a few seconds after ultraviolet light irradiation. In addition, the coating material system has characteristics of high hardness, excellent adhesion and excellent water resistance.

Description

technical field [0001] The invention relates to a coating for glass substrates, in particular to a transparent heat-insulating coating system for glass substrates. technical background [0002] Transparent heat-insulating coatings are generally coated on the surface of transparent glass, which can strongly absorb ultraviolet light, pass through most visible light, and have high reflectivity to near-infrared rays, so that the internal space enclosed, such as indoors and cars etc. To achieve the purpose of heat insulation and energy saving, it has important economic and social benefits in today's increasingly tense energy supply and aggravated environmental pollution. [0003] The early transparent heat-shielding coatings were vapor-deposited one or more layers of metal films such as gold, silver, copper, tin, chromium, titanium, etc. on the glass surface. This kind of coating has obvious heat insulation and energy-saving effects, but it has a high reflectivity to visible lig...
