Method for obtaining thermoplastic composites reinforced with short cellulose fibers

摘要

method for thermoplastic composite short fibre reinforced is characterized by the fact that in the two granulatach composite a and b modifies the polymer to interfazu0119 - cellulose fibres using kompatybilizatora or antykompatybilizatora.granular composite a and b is obtained by mixing the molten polymer can warp fibers of cellulose derivatives in relation to 70: 30% by weight to 50: 50% by weight, with the participation, in granulacie and kompatybilizatora, which is miscible with the wax polimerowy polymer warp of 0.5 - 3% by weight in relation to the polymer warp, and in granulacie b with the participation antykompatybilizatora, which is wax polimerowy niemieszalny with polymer warp of 0.25% - 3% by weight in relation to the polymer warp.then the granules a and b mixed in molten ratio from 1: 1 to 3: 1 during the further processing injection or extrusion to form composite of differentiated interphase cells fibre fabric. as the warp is polpropylen polymer, polyethylene, poly (ethylene terephthalate), poly (butylene terephthalate), polylactide, polyamide or polioksymetylen.as kompatybilizator or antykompatybilizator apply polimerowy polypropylene wax, polyethylene, copolymer of ethylene glycol, styrene acrylic copolymer or other polymeric waxes. the polymer and fibers in the granulacie embedded in an overwrap a and b are the same.
