C5 petroleum resin act as a tackifying resin

C5 petroleum resin has hot melt adhesive, high peel strength. May be due to the best compatibility of C5 petroleum resin and the system. At present, in the field of domestic hot melt research, many materials can be added as a modifier to the formula to increase the bonding properties of hot melt adhesives and other properties, but the ethylene elastomer as aluminum-plastic composite pipe with hot melt. The study of plastic modifiers has not been reported.
In the hot melt adhesive formula by adding a certain amount of ethylene-based elastomer, hot melt adhesive can make better wetting and aging resistance. HDPE and linear low density polyethylene (LLDPE) as the main resin, dicumyl peroxide (DCP) as the initiator, maleic anhydride (MAH) as the main monomer for grafting and then the grafted, tackifier and other additives were blended and extruded to prepare aluminum-plastic composite pipe with high bonding strength and good flowability. The effects of the ratio of raw materials, grafting monomer, DCP, tackifying resin and ethylene elastomer on the properties of the hot melt were discussed. The structure of the graft was studied by FT-IR characterization.
