Problems solved by technology

[0003] Due to the double transparency of glass and thermal insulation coating, it is easy to produce color difference in the construction process of glass thermal insulation coating, resulting in the problem of uneven coating film
Especially when the glass thermal insulation coating is adjusted to achieve a better thermal insulation effect, when the formula is adjusted to a lower visible light transmission rate, the color difference is more likely to appear, and the difficulty of construction is greatly increased.
Generally speaking, when the visible light transmission rate is lower than 65%, it is basically impossible to obtain heat-insulating coated glass with uniform color.
This greatly limits the scope of use of glass thermal insulation coatings, and also seriously reduces its thermal insulation performance in actual use.

Abstract

The invention discloses heat-insulating coated glass, a construction method thereof and a heat-insulating coating. The heat-insulating coating is a spot coating, the spot coating comprises a pluralityof heat-insulating coating spots coating substrate glass, and the total area of the spots on the substrate glass accounts for 5%-95% of the area of the coating area. The construction method comprisesthe following steps: manufacturing a covering film, adhering the covering film to the glass, coating the covering film with the glass heat-insulating coating, and after the glass heat-insulating coating is cured, removing the covering film to leave a spot-shaped coating on the surface of the glass. The construction method is simple, the heat insulation amount and the visible light transmittance of the heat insulation coated glass are convenient to adjust during construction, glass heat-insulating coatings with different light transmittances can be uniformly constructed according to pattern changes, particularly, the visible light transmittance is low, and the heat insulation coated glass does not have the defect of chromatic aberration.

technical field [0001] The invention relates to the technical field of heat-insulating coated glass, in particular to a heat-insulating coated glass, a construction method thereof, and a heat-insulating coating. Background technique [0002] Traditional glass thermal insulation coatings are mainly composed of transparent resins and nanomaterials capable of absorbing infrared rays, such as indium tin oxide (ITO), antimony tin oxide (ATO) and tungsten oxide (WO 3 )Wait. [0003] Due to the double transparency of the glass and the thermal insulation coating, the glass thermal insulation coating is prone to chromatic aberration during construction, resulting in the problem of uneven coating. Especially when the glass thermal insulation coating is adjusted to a lower visible light transmission rate in order to achieve a better thermal insulation effect, the color difference is more likely to appear, and the construction difficulty is greatly increased. Generally speaking, when ...
