Abstract

The invention discloses a UV (ultraviolet) single-side adhesive tape with adhesive failure after ultraviolet irradiation and a preparation method of the adhesive tape. The UV single-side adhesive tape comprises a transparent base film, a UV adhesive layer and a single-side release film, wherein the UV adhesive layer coats the surface of the transparent base film, the single-side release film covers the surface of the UV adhesive layer, and the UV adhesive layer comprises, in weight percentage, 38%-80% of UV adhesives, 0.5%-2.5% of curing additives, 9%-20% of ethyl ester and 10%-40% of methylbenzene. The UV adhesive layer is prepared by a specific formula, so that the UV single-side adhesive tape has high adhesive force, wafers cannot fly apart in cutting, grinding and the like, workpieces can be effectively protected, after UV irradiation, adhesive failure is rapid, adhesive failure effects are good, adhesive residues are omitted, and machining production operation is facilitated.

Description

technical field [0001] The invention relates to the technology in the field of adhesive tapes, in particular to a UV single-sided adhesive tape that loses adhesion after being irradiated by ultraviolet rays and a preparation method thereof. Background technique [0002] In the process of wafer grinding, dicing, various silicon wafers, packaging substrates, ceramics, glass, crystal fine electronic parts, and processing and cutting of small parts of various materials, tapes are often used for protection. In the prior art, the adhesive tape used for processing protection generally has the problems of insufficient adhesion and poor adhesion loss effect, so that it cannot protect the workpiece well, and after the workpiece is processed, the tape is difficult to peel off from the workpiece. It is easy to leave residual glue after peeling off, which brings inconvenience to processing and production operations. Contents of the invention [0003] In view of this, the present inven...
