Abstract

The invention relates to the technical field of ultraviolet curing adhesive, in particular to a hydrolysable ultraviolet curing adhesive and a method for preparing the same. The curing adhesive comprises the following components in part by weight: 30 to 70 parts of prepolymer, 15 to 60 parts of reactive diluent, 0 to 10 parts of coupling agent, 1 to 10 parts of photoinitiator and 0.1 to 2.5 parts of auxiliary agent, wherein the prepolymer has a unique structural formula. The preparation method comprises the following steps of: performing vacuum dehydration on the reactive diluent at the temperature of between 110 and 120 DEG C for 1 to 2 hours; cooling the reactive diluents; adding the prepolymer, the coupling agent and the photoinitiator into the reactive diluents when the temperature is reduced to the room temperature; stirring the mixture for dissolution; and finally adding the auxiliary agent. The ultraviolet curing adhesive is high in fluidity, easy to coat and quick in curing, the curing matters have the characteristics of hardness, crispness and low shrinkage ratio, and the curing adhesive is suitable for mechanical processing; and the curing adhesive is high in water adsorption, susceptible to peptization in water, low in cost and wide in application range. The preparation method is characterized by simple synthetic reaction process, and is easy to operate.

Description

technical field [0001] The invention relates to the technical field of ultraviolet curable adhesives, in particular to a hydrolyzable ultraviolet curable adhesive and a preparation method thereof. Background technique [0002] In the grinding and manufacturing process of glass, crystal, jewelry, optical lenses, high-end handicrafts, electronic processing and other industries, a special adhesive is required, which is easy to coat; fast curing, and the cured product has the properties of hard and brittle and low shrinkage. Good bonding strength, suitable for temporary bonding or covering during mechanical processing such as grinding; after processing, the cured product is highly water-absorbent, and the adhesive film is easily hydrolyzed in water to separate the bonded object; traditional UV-cured adhesive Although the adhesive can have good bonding strength, the adhered object is not easy to separate after processing, or the adhesive film on the object is not easy to remove a...
