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 ultraviolet-proof adhesive for a glass functional film. The adhesive has excellent ultraviolet shielding function and comprises components by weight as follows: 44%-49% of a pressure-sensitive adhesive, 2.4%-2.7% of an ultraviolet absorber and 48%-54% of a solvent, wherein the ultraviolet absorber comprises mono(hydroxyphenyl)triazine compound and tris(hydroxyphenyl)triazine compound in a weight ratio of 1 : (1.7-2.2). According to the adhesive, the tris(hydroxyphenyl)triazine compound which has excellent shielding capacity on the whole ultraviolet band is selected and matched with a special proportion of mono(hydroxyphenyl)triazine compound to serve as the ultraviolet absorber, so that under the conditions of small addition amount of the ultraviolet absorber and thin coating, the obtained adhesive has the same ultraviolet shielding capacity as an adhesive only adopting the tris(hydroxyphenyl)triazine compound, accordingly, not only the cost of the adhesive is reduced greatly, but also lower yellow index is realized, and the ultraviolet-proof adhesive is particularly suitable for functional films of light transmitting glass of a building or a vehicle.

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 mark...
