The first and third portions partially overlap with the second portion in opposing first and second overlapping regions, respectively.
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.
