Abstract

The invention discloses an ultraviolet-curing hot-melt pressure-sensitive adhesive high in peeling strength, and a preparation method and applications thereof. The ultraviolet-curing hot-melt pressure-sensitive adhesive high in peeling strength comprises, by weight, 10 to 30 parts of a segmented copolymer, 20 to 50 parts of a UV-curable acrylic ester hot-melt pressure-sensitive adhesive, 20 to 35parts of a tackifying resin, 0.1 to 1 part of a coupling agent, 8 to 35 parts of a rubber plasticizer, 0.1 to 1 part of a photoinitiator, and 0.1 to 1 part of an antioxidant. The peeling strength, theprimary viscosity, and the applying effect on nonpolar base materials of the ultraviolet-curing hot-melt pressure-sensitive adhesive are improved obviously; the ultraviolet resistance and the high temperature resistance are also improved greatly.

Description

technical field [0001] The present invention relates to the technical field of hot-melt pressure-sensitive adhesives, to a hot-melt pressure-sensitive adhesive and its preparation method and application, in particular to a high peel strength UV-curable hot-melt pressure-sensitive adhesive and its preparation method and application. Background technique [0002] Hot-melt pressure-sensitive adhesives generally refer to pressure-sensitive adhesives composed of thermoplastic elastomers, tackifying resins, plasticizers and antioxidants as the main components. Among them, thermoplastic elastomers mainly refer to polymer copolymers such as SIS, SBS, SIPS, and SEBS, and tackifying resins mainly refer to rosin resins, terpene resins, C5 petroleum resins, C9 petroleum resins or C5 / C9 copolymerized petroleum resins. Agents mainly include naphthenic oil, white oil and low molecular weight polyisobutylene. This type of hot-melt pressure-sensitive adhesive has no solvent and water discha...
