Glass heat insulation film and preparation method thereof

Abstract

The invention discloses a glass heat insulation film and a preparation method thereof. The film comprises the following components: 10-20% of acrylic resin, 6-9% of butyl acetate, 6-9% of 2-(2H-benzotriazole-2-yl)-4-methylphenol, 10-15% of tin oxide and the like. The preparation method of the film comprises the following steps: (S1) adding the butyl acetate and the like into the acrylic resin, and sufficiently stirring and mixing, and grinding into slurry; (S2) adding dimethyl glutarate and the like, stirring at a high speed and uniformly dispersing. The glass heat insulation film disclosed by the invention is a liquid film; after natural normal-temperature hardening, the glass surface is processed by a roller painting process, and the glass heat insulation film is beautiful and durable.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a glass heat insulation coating film and a preparation method. Background technique [0002] After long-term sunlight exposure of architectural glass, there will be problems such as performance change, serious aging, and greatly shortened service life. In serious cases, the glass may even be broken, causing personal safety accidents. In order to prevent architectural glass from being affected by solar thermal radiation for a long time, traditional The treatment measures are usually the method of glass film. However, the raw material of glass film is usually plastic film, which has poor aging resistance and is prone to bubbles after long-term use, which not only affects the appearance of the glass, but also affects the heat insulation performance, and the construction is extremely difficult. It is convenient, especially in large shopping malls, hotels, airport stations and other c...

Problems solved by technology

[0002] Architectural glass exposed to sunlight for a long time will cause performance changes, serious aging, and greatly shortened service life. In severe cases, it may even cause glass breakage and cause personal safety accidents. In order to prevent architectural glass from being affected by solar heat radiation for a long time, traditional The treatment measures are usually the method of glass film, but the raw material used for glass film is usually plastic film, which has poor aging resistance and is prone to bubbles after long-term use, which not only affects the appearance of the glass, but also affects the heat insulation performance, and the construction is extremely poor. Convenience, especially in large shopping malls, hotels, airport stations and other ceilings that use transparent light. When using the glass film method, if it coincides with the hot summer sun in the sky, the labor intensity of film processing is very high. If the film is applied on the inside of the building If it is a large-scale scaffolding, it is necessary to build a large-scale scaffolding. Due to the many connection points between the steel structure pillars and the glass on the top of the building, the link structure is complex, and it is very difficult to apply the film; Direct erosion will seriously affect the service life of the plastic film
