Abstract

The invention provides an adhesive, a preparation method and application thereof. The adhesive is prepared from the following raw materials in percentage by mass: 40-90% of an acrylic monomer, 5-50% of a hydrogen bond acceptors and 1-5% of an initiators. Wherein the acrylic monomer and the hydrogen bond acceptor form a polymerizable deep eutectic solvent. The preparation method of the adhesive comprises the following steps: mixing the raw materials, and reacting to obtain the adhesive. The adhesive is used for producing optical products. The adhesive provided by the invention can be well dissolved by water, so that the adhesive is separated from an adhered base material, and the cost and safety of raw materials are reduced while the performance is improved.

Description

technical field [0001] The application relates to the field of materials, in particular to an adhesive and its preparation method and use. Background technique [0002] Adhesives play important roles in everyday life such as medical, electronics, home construction and automotive. In the past decade, many adhesives with unique uses have been successfully developed, including underwater adhesives, water-based adhesives, low-temperature resistant adhesives, etc. However, in other special fields, such as in the process of drilling and slicing optical lenses, it is necessary to use glue to firmly adhere the processed object to the bracket during processing. After that, the workpiece needs to be disengaged from the bracket under certain external stimuli. Traditionally, methods such as immersion in organic solvents, heating, and UV irradiation are usually required to separate adhesives and adhesives, but this is not only energy-intensive and time-consuming, but also causes enviro...
