Problems solved by technology

Glass film using pressure-sensitive adhesive as an adhesive is generally suitable for manual installation. During the installation process, water should be sprayed between the glass and the pressure-sensitive adhesive. This method of attachment is slow in drying speed and is not suitable. mechanized mass production

Abstract

The invention discloses a UV (ultraviolet) light-curable adhesive for a glass film and a preparation method thereof. The preparation method of the adhesive comprises the following steps: mixing a prepolymer, a photo-initiation monomer, pectin, photoinitiator, active diluent and acetone; and performing uniform ultrasonic dispersion to obtain the UV light-curable adhesive for a glass film. The adhesive can be cured under the irradiation of UV light, thereby facilitating use for industrial construction. Besides, the adhesive has high adhesiveness and favorable transparency and weather resistance.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a UV light-curing adhesive for glass film and a preparation method thereof. Background technique [0002] In recent years, the number of housing construction in the country has grown rapidly, and the total housing construction volume has increased year by year, resulting in building energy consumption accounting for nearly a quarter of the total energy consumption in society, and is still in an increasing trend year by year. Building energy consumption is mainly composed of air conditioning, heating and cooling. , lighting, cooking and household appliances, among which heating or cooling account for the vast majority of energy consumption. Doors and windows account for about 20%-30% of the total building area, and the energy loss is as high as 50%. In some public building fields, the proportion of curtain walls is even as high as 70%, and the energy loss is even more serious. However, m...
