UV-CROSSLINKED HOT-MELT PRESSURE-SENSITIVE ADHESIVE USED FOR POLYVINYL CHLORIDE INSULATION ADHESIVE TAPE
The present invention provides a UV-crosslinked hot-melt pressure-sensitive adhesive used for a polyvinyl chloride (PVC) insulation adhesive tape, made by mixing a polymer of vinyl monomers, functional monomers, special soft monomers, and photoinitiators with a tackifying resin and an antioxidant in certain proportions; the composition of the photoinitiator polymer contains a copolymer of one or more polymerizable photosensitive initiators and acrylate monomers, or a mixture of oligomers of one or more polymerizable photosensitive initiators and acrylate high polymers. The PVC adhesive tape made using such a pressure-sensitive adhesive has the advantages of excellent mechanical properties, bonding performance, and resistance to high temperatures, and is energy-saving and environmentally friendly; the present invention overcomes the defect of the prior art that a relatively long thermal oven is needed to volatilize a solvent in the glue when coating a PVC adhesive tape, which is applicable for wrapping and strapping cable bundles in different positions of the body of an automobile, can satisfy the requirement for uses on high temperature-resistant positions of an engine inside the automobile, and reaches a long-term temperature resistance level of 125° C.

METHOD FOR MANUFACTURING HIGH TEMPERATURE-RESISTANT POLYVINYL CHLORIDE ADHESIVE TAPE
The present invention relates to a method for manufacturing a high temperature-resistant polyvinyl chloride adhesive tape, and more particularly to a method and a production process for manufacturing a high temperature-resistant adhesive tape by applying a UV-crosslinkable hot-melt pressure-sensitive adhesive to a high temperature-resistant polyvinyl chloride film. The high temperature-resistant polyvinyl chloride film is a high temperature-resistant material containing a liquid polymeric plasticizer, a solid polymeric plasticizer, and a heat stabilizer. The hot-melt pressure-sensitive adhesive can be directly coated onto the high temperature-resistant polyvinyl chloride film at 130-150° C.; and then crosslinked and cured by UV irradiation, to make a high temperature-resistant polyvinyl chloride adhesive tape. Compared with conventional polyvinyl chloride adhesive tapes, the high temperature-resistant polyvinyl chloride adhesive tape manufactured using the method for manufacturing a novel high temperature-resistant polyvinyl chloride adhesive tape provided in the present invention has the advantages of non-volatility and resistance to high temperature and is highly environmentally friendly.
