Abstract

The invention discloses an adhesive master batch for preparing polypropylene hot melt adhesive and a preparation method thereof. The masterbatch is composed of the following components in parts by weight: 70-90 parts of polypropylene, 10-30 parts of polymer wax, 1.5-5 parts of graft monomer, 0.1-0.5 part of initiator, the second grafting unit 1.5-5 parts of electron donor, 0.1-0.5 parts of electron donor. The preparation method is to dissolve the grafting monomer, initiator, second grafting monomer and electron donor in acetone solution, and then add them together with polypropylene and polymer wax to a high-speed mixer and mix them evenly. The screw extruder blends and granulates to obtain the adhesive masterbatch. The adhesive masterbatch of the present invention is effectively compounded with polypropylene resin and additives to obtain a polypropylene hot melt adhesive with high adhesive performance. The maximum T-peel strength can reach more than 130N / 25mm, which is suitable for PP-R composite pipes. Requirements for the use of hot melt adhesives.

Description

technical field [0001] The invention belongs to the field of polymer adhesives, and in particular relates to an adhesive masterbatch for preparing polypropylene hot-melt adhesives and a manufacturing method thereof, in particular to an adhesive masterbatch for preparing hot-melt adhesives for random copolymerized polypropylene composite pipes and its method of manufacture. Background technique [0002] Random copolymerized polypropylene (PP-R) composite pipes have developed rapidly in recent years because they have the advantages of both ordinary PP-R pipes and metal pipes. The composite pipe mainly has a five-layer structure, namely PP-R / hot melt adhesive / metal / hot melt adhesive / PP-R. Among them, the role of hot melt adhesive is to bond non-polar PP-R and polar metal together. Therefore, the performance of hot melt adhesive directly determines the quality of PP-R composite pipe. At present, hot-melt adhesives for PP-R composite pipes mainly rely on imports. The hot-melt a...
