Abstract

The invention discloses an antibacterial plastic rattan and a preparation method thereof. The antibacterial plastic rattan comprises 100 parts of a PE mixture, 10 parts of glycidyl methacrylate, 0.1 part of an initiator, 3-8 parts of nano-zinc oxide, 0.1 part of an accelerant and 3-5 parts of an antioxidant; the PE mixture comprises UHMWPE and LDPE; and the surface of the nano-zinc oxide is treated by being contaminated with L-cysteine. The preparation method comprises the following steps of: mixing a graft copolymer, the modified nano zinc oxide, the accelerant, the antioxidant and an ultraviolet light absorber; adding the mixture into a screw extruder for melt extrusion; and performing cooling, shearing and granulating after extrusion. The prepared plastic rattan has a good antibacterialproperty.

Description

technical field [0001] The invention relates to the technical field of plastic processing, more specifically, it relates to an antibacterial plastic rattan and a preparation method thereof. Background technique [0002] Rattan is a natural weaving material with simple color and luster, which can be used to weave daily necessities such as fruit baskets, vegetable baskets, and seats. However, the original processing procedure of rattan material is quite complicated. It has to go through cooking, drying, bleaching, disinfection, and napping. The processing steps are cumbersome and not suitable for mass production. In addition, if natural rattan is used without restraint, it will destroy biodiversity and cause environmental problems. [0003] Polymer materials are rich in sources, easy to process, and have the advantages of good mechanical properties, so they always have great application value in life, especially olefin polymers such as polyethylene, through appropriate proces...
