Heatretaining insulating mold coating produced from glass as well as preparing and coating method

Abstract

This invention discloses a method for preparing and coating glass heat-insulating paint. The paint is composed of: antimony-doped tin oxide 30-55 parts resin 45-70 parts, surfactant 0.01-0.2 part, defoamer 0.05-0.2 part, film-forming aid 1-5 parts. The paint has such advantages as high IR blocking ability, high visible light permeability (50-70%), no light pollution, low heat transfer coefficient (0.3-0.4), low requirement for raw materials, simple process and easy coating.

Description

technical field [0001] The invention belongs to the technical field of application of energy-saving materials, and more specifically relates to glass thermal insulation coatings such as doors and windows of buildings and vehicles, and also relates to a preparation method of the coating and a coating method on glass. Background technique [0002] In recent years, the energy saving of buildings and vehicles has become more and more recognized and valued by people. my country's Ministry of Construction, Ministry of Communications and other ministries and commissions have successively issued regulations on energy saving of buildings and vehicles, and in various news media See you frequently. As far as the energy saving of buildings is concerned, two aspects are mainly concerned, one is the wall material and the corresponding thermal insulation coating is applied to the wall; the other is the door and window glass. [0003] At present, the energy-saving measures for the door and ...

The advantage is that it can not only make the glass rich and colorful, but also has an appropriate transmittance to visible light, a certain reflectivity to near-infrared rays, and a very low transmittance to ultraviolet rays. Therefore, people call this kind of glass solar control glass. Compared with ordinary glass, the sunshade performance is good, but the disadvantages are: the light transmittance is greatly affected; there is light pollution; there is no change to the heat transfer coefficient

The heat reflective film is pasted on the glass surface to ensure a certain amount of visible light in the room or compartment. It has high infrared reflectivity (IR) and low solar heat gain coefficient (SHGC), which can ensure that the indoor temperature will not rise in hot summer Too much can reflect the saving of air-conditioning electricity costs, but the lack of it has a greater impact on light transmittance and light pollution.

[0008] Low-emissivity film, also known as LOW-E film, can pass a certain amount of short-wave solar radiation energy, allowing solar radiant heat (near infrared rays) to enter the room, and at the same time can radiate more than 90% of indoor object heat sources (such as heating equipment) The long-wave infrared (far infrared) is reflected back to the room, so it can play a significant role in keeping warm and saving energy when used in buildings in cold regions, but the heat insulation effect is lacking.
