Embodiment 1

[0015] An antibacterial highly filled degradable plastic, comprising the following raw materials in parts by weight: 25 parts of polybutylene succinate, 30 parts of modified starch, 2 parts of glycerin, and 3 parts of ZnO / Ag nanocomposite antibacterial agent.

[0016] The results of the inhibition zone test showed that the antibacterial highly filled degradable plastic had an inhibition rate of 99.98% against Escherichia coli and Staphylococcus aureus.

Embodiment 2

[0018] An antibacterial highly filled degradable plastic, comprising the following raw materials in parts by weight: 80 parts of polybutylene terephthalate adipate, 75 parts of modified starch, 10 parts of paraffin, and 5 parts of ZnO / Ag nanocomposite antibacterial agent share.

[0019] The results of the bacteriostatic zone test showed that the antibacterial highly filled degradable plastic had an inhibition rate of 99.99% against Escherichia coli and Staphylococcus aureus.

Embodiment 3

[0021] A degradable plastic highly filled with an antibacterial agent, comprising the following raw materials in parts by weight: 62 parts of polylactic acid, 55 parts of modified calcium carbonate, 7 parts of acetyl tributyl citrate, and 4 parts of ZnO / Ag nanocomposite antibacterial agent.

[0022] The results of the inhibition zone test showed that the antibacterial highly filled degradable plastic had an inhibition rate of 99.97% against Escherichia coli and Staphylococcus aureus.

Abstract

The invention discloses antibacterial high-filled degradable plastic. The antibacterial high-filled degradable plastic is prepared from, by weight, 25-80 parts of biodegradable materials, 30-75 parts of filling powder, 2-10 parts of auxiliaries and 3-5 parts of nano antibacterial agents, wherein the nano antibacterial agents adopt ZnO-Ag nanocomposite antibacterial agents. The plant degradable materials comprise any one of poly(butylene succinate), polybutylene hexanedioic acid terephthalate and polylactic acid; the filling powder comprises any one of wood powder, modified starch, modified calcium carbonate, modified talcum power, modified pulverized fuel ash, montmorillonoid and kaolin. The antibacterial high-filled degradable plastic is easy to degrade, good in plasticity, capable of resisting bacteria and preventing corrosion and suitable for being applied to production and manufacture of various plastic products.

Description

technical field [0001] The invention relates to an antibacterial highly filled and degradable plastic, which belongs to the technical field of plastic preparation.
