METHOD FOR MANUFACTURING HIGH-TEMPERATURE-RESISTANT POLYVINYL-CHLORIDE ADHESIVE TAPE

WIPO Patent Application WO/2017/133122

A1

The present invention relates to a method for manufacturing a high-temperature-resistant polyvinyl-chloride adhesive tape; provided are a method and 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 macromolecular plasticizer, a solid macromolecular 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; then, ultraviolet light is used for crosslinking and curing, to make a high-temperature-resistant polyvinyl-chloride adhesive tape. The high-temperature-resistant polyvinyl-chloride adhesive tape manufactured using the new type of method for manufacturing a high-temperature-resistant polyvinyl-chloride adhesive tape, in contrast to conventional polyvinyl-chloride adhesive tapes is has the advantages of non-volatility and resistance to high temperatures, and is very environmentally friendly.
