Abstract

The invention provides a heat-resistant UV viscosity breaking film. The heat-resistant UV viscosity breaking film comprises a substrate layer, a UV photosensitive adhesive layer and a release film layer sequentially. The invention further provides a preparation method of the UV photosensitive adhesive layer. The UV photosensitive adhesive layer comprises the ingredients in percentage by weight: 30% to 50% of solvent type high-temperature resistant polyacrylate pressure-sensitive adhesive, 1% to 25% of micromolecular mixed additives, 0.1% to 3% of difunctional or polyfunctional special additive, 0.1% to 1.5% of photoinitiator, 0.5% to 2% of curing agent and 35% to 60% of solvent. The invention further provides a preparation method of the heat-resistant UV viscosity breaking film. According to the heat-resistant UV viscosity breaking film and the preparation method thereof, the sealing performance and high-temperature resistance of a UV photosensitive adhesive to corona PET substrates are improved, base coat treatment technologies are reduced, and the product structure is optimized.

Description

technical field [0001] The invention belongs to the technical field of functional adhesive tapes, and relates to a UV mucous reducing film, in particular to a heat-resistant UV mucous reducing film and a preparation method thereof. Background technique [0002] With the rapid development of electronic products, the requirements for functional materials such as functional tapes are getting higher and higher. At present, UV mucous-reducing tapes are emerging among functional tapes, and are mainly used in the protection of wafer cutting process and electronic glass reprocessing process. During the wafer cutting and picking process, the UV adhesive film is mainly based on a PO film with a certain degree of flexibility, which is convenient for attaching to the curved surface of the wafer; while the UV adhesive film based on PET is mainly used for For flat electronic glass, there is no specific requirement for the softness of the tape, but the requirement for its high temperature...
