Hydrolysis UV (ultraviolet) adhesive for temporary protection as well as preparation method and application of hydrolysis UV adhesive

Abstract

The invention discloses a hydrolysis UV adhesive for temporary protection as well as a preparation method and application of the hydrolysis UV adhesive. According to the hydrolysis UV adhesive, the self-made urethane acrylate reacts with the monofunctional acrylate monomer, so that the adhesive is endowed with good adhesive force; meanwhile, the flexibility of the adhesive is improved by adjusting the ratio of the urethane acrylate to the acrylate monomer; on the basis of a heat-water dual effect, a proper amount of pyrolytic adhesive filler is introduced, and the volume expansion of the pyrolytic adhesive filler after being heated to a specific temperature is utilized to remarkably reduce the adhesive force of the adhesive film, so that a gap is formed between an adhesive base material and the adhesive film, and therefore, rapid invasion of hot water during water boiling is realized by utilizing the hydrophilicity of the adhesive film, and the adhesive film spontaneously, rapidly and completely falls off; the hydrolyzed UV adhesive has the characteristics of low viscosity, high fluidity and convenience in adhesive dispensing; the cured adhesive film is good in flexibility and relatively high in bonding strength; and after heating, the bonding strength of the adhesive film is rapidly reduced, and the adhesive film can rapidly and completely fall off through water boiling without residues.

Description

Technical Field

[0001] The present invention belongs to the field of adhesives, and particularly relates to a hydrolyzable UV glue for temporary protection, a preparation method thereof, and an application thereof. Background Art

[0002] With the continuous improvement of the requirements for material processing accuracy and environmental protection in modern industry, when processing precision materials such as optical lenses, glass, and crystal, it is often necessary to adopt temporary bonding and protection technologies in key processes such as cutting and grinding. Traditional processes mostly rely on acidic or alkaline solvents or organic solvents to remove adhesives, but such methods not only corrode equipment, pollute the environment, but also have high costs. For this reason, hydrolyzable UV glue has emerged with its unique advantages. After the temporary fixing and protection operation is completed, this material can be peeled off without a trace only by water boiling treatment, and there is no need to contact acids, alkalis, or organic solvents throughout the process, combining environmental protection and economy. This characteristic makes it widely used in fields such as the processing of precision optical components, the cold processing of high-hardness materials, and the temporary positioning of complex components, effectively balancing the dual requirements of production efficiency and environmental protection compliance.

[0003] However, the current hydrolyzable UV glue generally has the following problems in application: First, the bonding strength of the hydrolyzable UV glue is often not high after curing, and the temporarily bonded objects are prone to displacement or even falling off during the processing, resulting in a reduction in production yield; second, the hydrolyzable UV glue uses a water boiling debonding process, and the water boiling time is relatively long, with low efficiency; third, the flexibility of the hydrolyzable UV glue is poor, and it is prone to breakage or remain on the glass surface during the water boiling and peeling process, and is not easy to remove.

[0004] Therefore, developing a hydrolyzable UV glue with both high bonding strength and good flexibility, which can be quickly and completely peeled off after water boiling, is the focus of research in this field. Summary of the Invention
