Problems solved by technology

[0003] Due to the double transparency of glass and glass 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 a uniform color heat insulation film layer.
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 a glass insulation coating and a construction method thereof. The glass insulation coating is a spot coating, which comprises a plurality of spots of insulation paint covered on base plate glass, the total area of the spots on the base plate glass accounts for 5-95% of the area of a coated area. The construction method comprises the following steps: manufacturing a coveringfilm, pasting the covering film onto glass, coating the covering film with the glass insulation paint, tearing off the covering film after the glass insulation paint is solidified, and leaving a spotted coating on a glass surface. The construction method is simple, the insulation quantity and visible light transmittance of the glass insulation coating are convenient to adjust during construction,the glass insulation paint with different light transmittances, especially the glass insulation paint with low visible light transmittance, can be uniformly constructed, and the glass insulation coating does not have a chromatic aberration defect.

Description

[technical field] [0001] The invention relates to a glass coating, in particular to a glass thermal insulation coating and a construction method thereof. [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 glass and glass 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 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 the visible light transmission rate is l...
