Abstract

The invention relates to an ultraviolet curing urethane acrylate adhesive and a preparation method thereof, disclosing an approach for obtaining an environment-friendly adhesive. The adhesive is mainly used as a bonding agent for electric products and can be applied to the bonding of PDP displays, LED displays, OLED displays and FPD displays. The adhesive is prepared by using isobornyl acrylate which is an active diluent as a solvent for replacing methylbenzene and benzene, adding toluene diisocynate into polyether, using a chain extender in the reaction, and finishing the reaction within three hours. The adhesive cannot generate poisonous and harmful substances in the processes of production or use and has no pollution to the environment. Meanwhile, the invention has short reaction time and low reaction temperature and can achieve the purpose of energy saving.

Description

Technical field [0001] The invention belongs to the technical field of chemical industry, and is an environment-friendly, low-viscosity, high-efficiency and energy-saving UV curing adhesive. It can be used as an adhesive for electronic appliances, such as the bonding of PDP, LED, OLED, and FPD displays; it can also be used to manufacture optical film materials, such as PET anti-scratch film, anti-reflection film, anti-glare film and isolation film etc. Background technique [0002] At present, the existing photocurable polyurethane acrylate adhesives are mainly used in the manufacture of wood coatings and inks, etc., but its bonding strength, elongation, shrinkage, moisture resistance and electrical properties are not as good as those in the electronics industry. the standard used. With the rapid development of the electronics industry, the demand for high-performance UV-curable adhesives is increasing. However, toxic solvents such as toluene and benzene are often used in...
