Problems solved by technology

Because the thickness of the coating will affect the clarity of the functional film, the existing functional film generally only adds tris (hydroxyphenyl) triazine compound to the adhesive, but the tris (hydroxyphenyl) triazine compound is expensive and is About 3 times that of mono(hydroxyphenyl) triazine compounds, resulting in high price of this kind of functional film, so it is not conducive to popularization and application

Abstract

The invention provides an adhesive for an ultraviolet-resistant glass functional film with excellent ultraviolet shielding function, the adhesive comprises a pressure-sensitive adhesive of 44-49% by weight, 2.4-2.7% of an ultraviolet absorber and 48‑54% solvent, and the ultraviolet absorber is composed of a mono(hydroxyphenyl) triazine compound and a tri(hydroxyphenyl) triazine compound in a weight ratio of 1:1.7‑2.2. In the adhesive of the present invention, by selecting a tris(hydroxyphenyl)triazine compound with excellent shielding power for the entire ultraviolet band and a specific ratio of a mono(hydroxyphenyl)triazine compound as an ultraviolet absorber, the obtained adhesive The adhesive has the same UV shielding ability as the single use of tris(hydroxyphenyl)triazine compound when the amount of ultraviolet absorber added is small and the coating is thin, which not only greatly reduces the cost of the adhesive, but also has a lower Yellow index, especially suitable for the use of light-transmitting glass functional films for buildings or vehicles.

Description

technical field [0001] The invention relates to an adhesive, in particular to an adhesive for pasting a functional film on glass, and more particularly to an adhesive for an ultraviolet-resistant glass functional film with excellent ultraviolet shielding function. Background technique [0002] In addition to visible light, sunlight also contains ultraviolet rays and near-infrared rays. In order to reduce the adverse effects of ultraviolet rays and infrared rays on the interior and the human body, various functional films are usually pasted on the transparent glass of buildings or vehicles. Functional films generally include anti-corrosion Scratch layer, main film layer, adhesive layer and release layer, the main film layer is generally composed of polyester film and functional coating coated on the polyester film. In order to improve the clarity of the functional film, a type of protective film that imparts UV protection to the adhesive layer has begun to appear on the marke...
