Abstract
The application relates to an anti-plasticizer viscosity-reducing high-molecular composition and a UV viscosity-reducing adhesive tape, which comprises the following raw materials in mass parts: 20-30 parts of silicone-modified crosslinking type polyurethane acrylate, 8-15 parts of polyurea-based acrylate, 5-20 parts of active diluent, 1-2 parts of crosslinking agent, 0.5-2 parts of curing agent and 0.3-1 part of photoinitiator; the silicone-modified crosslinking type polyurethane acrylate prepared by using specific monomers and a specific preparation method contains rich multiple functional groups and fully participates in the photocuring reaction; the initial adhesion and bonding strength of the UV viscosity-reducing adhesive tape prepared from the high-molecular composition are stably guaranteed, and the UV viscosity-reducing adhesive tape has excellent plasticizer resistance.
