Abstract

The invention relates to PP antibacterial plastic and a preparation method thereof. The antibacterial plastic is prepared from, by weight, 100-150 parts of polypropylene, 3-5 parts of dodecyl trimethyl ammonium chloride, 2-5 parts of chitosan, 2-5 parts of glycine betaine, 2-5 parts of nano zinc oxide powder, 3-5 parts of nano calcium oxide, 0.5-2 parts of zinc stearate, 0.5-2 parts of white oil, 0.5-5 parts of a coupling agent, 0.5-2 parts of nonylphenol polyoxyethylene ether, 0.1-1 parts of ethylene-1-octene copolymer, 0.5-1 part of antioxidant, 0.1-3 parts of styrene and maleic anhydride random copolymer and 0.5-2 parts of plasticizer.The antibacterial plastic is good in mechanical property and processability, good in flame retardancy, good in antibacterial performance and capable of being used for plastic thin films, pipes, plates and various plastic products.

Description

technical field [0001] The invention belongs to the technical field of polymers, and relates to an antibacterial plastic and a preparation method thereof, in particular to a PP 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 physical metho...
