Abstract
The invention relates to a high-temperature-resistant UV viscosity-reducing adhesive tape and a preparation method thereof, and belongs to the technical field of UV viscosity-reducing adhesive tapes. The high-temperature-resistant UV viscosity-reducing adhesive tape comprises a base material layer, an adhesive layer and a release layer which are sequentially arranged, wherein the adhesive layer is prepared from an adhesive; the adhesive is prepared from the following components in parts by weight: 100 parts of an acrylate polymer, 0.1 to 2 parts of a cross-linking agent, 1 to 3 parts of a photoinitiator, 0.2 to 0.8 part of an antioxidant and 35 to 100 parts of a first solvent; the acrylate polymer comprises the following components in parts by weight: 70-80 parts of a soft monomer, 20-30 parts of a hard monomer, 5-10 parts of a polyfunctional monomer, 0.1-1 part of an initiator, 0.05-0.2 part of a polymerization inhibitor, 1-7 parts of an end-capping reagent and 100-200 parts of a second solvent. The UV viscosity-reducing adhesive tape can still keep excellent viscosity-reducing performance after being subjected to high-temperature treatment, and the effect that the viscosity is not reduced or even improved after being subjected to high-temperature treatment can be achieved.
