Abstract

The invention relates to HDPE (High-Density Polyethylene) antibacterial plastic and a preparation method thereof. The antibacterial plastic is prepared from the following ingredients in parts by weight: 100-150 parts of HDPE, 3-5 parts of dodecyl trimethyl ammonium chloride, 2-5 parts of polyhexamethylene guanidine, 2-5 parts of glycine betaine, 2-5 parts of nano-zinc oxide powder, 3-5 parts of tourmaline powder, 0.5-2 parts of zinc stearate, 0.5-2 parts of white oil, 0.5-5 parts of coupling reagent, 0.5-2 parts of dibenzylidene sorbitol, 0.1-1 part of ethylene-octylene copolymer, 0.5-1 part of antioxygen, 0.1-3 parts of random copolymer of styrene and maleic anhydride and 0.5-2 parts of plasticizer. The antibacterial plastic disclosed by the invention has the advantages of good mechanical property, processability, flame retardant property and antibacterial property, and can be used for plastic films, tubular products, panels and various plastic products.

Description

technical field [0001] The invention belongs to the technical field of macromolecules, and relates to an antibacterial plastic and a preparation method thereof, in particular to an HDPE antibacterial plastic and a preparation method thereof. Background technique [0002] At present, plastic products play a very important role in people's daily life and industrial and agricultural production. However, with the change of people's health concept, it is gradually realized that a large number of various healing bacteria that are harmful to human health will grow on the surface of plastic products. In order to effectively prevent and kill the bacteria attached to the plastic surface, people usually add antibacterial agents to the plastic to make antibacterial plastic, so that the plastic itself has antibacterial properties, which can kill or kill the bacteria that are stained on the plastic within a certain period of time. Inhibition, compared with conventional chemical and physi...
