Embodiment 1

[0043] (1) Take 6 parts by weight of nano-zinc oxide, 4 parts of nano-titanium dioxide, 2 parts of ammonium dihydrogen phosphate, 2 parts of hydroxypropyltrimethylammonium chloride chitosan, and 25 parts of polyvinyl chloride , 6 parts of diethyl phthalate, 2 parts of chlorinated paraffin, 8 parts of polyamide resin, and 10 parts of polyisobutylene. The above components are mechanically mixed first, and mixed until the above-mentioned components are evenly mixed; (2 ) The materials in the step (1) after mechanically mixing uniformly are melted and extruded with a twin-screw extruder. It is divided into 3 sections: the temperature of the first section is 190°C, the temperature of the second section is 210°C, and the temperature of the third section is 230°C; (3) Wait for the material after twin-screw extrusion to cool before pelletizing, and after pelletizing, it is Prepared nano antibacterial plastics.

Embodiment 2

[0045] (1) Take 2 parts by weight of nano-zinc oxide, 1 part of nano-titanium dioxide, 5 parts of ammonium dihydrogen phosphate, 5 parts of hydroxypropyltrimethylammonium chloride chitosan, and 36 parts of polyvinyl chloride , 2 parts of diethyl phthalate, 5 parts of chlorinated paraffin, 18 parts of polyamide resin, and 5 parts of polyisobutylene. The above ingredients are mechanically mixed first, and mixed until the above ingredients are mixed evenly; (2 ) The materials in the step (1) after mechanically mixing uniformly are melted and extruded with a twin-screw extruder. It is divided into 3 stages: the temperature of the first stage is 175°C, the temperature of the second stage is 205°C, and the temperature of the third stage is 220°C; (3) Wait for the material after twin-screw extrusion to cool before pelletizing. After pelletizing, it is Prepared nano antibacterial plastics.

Embodiment 3

[0047] (1) Take 3 parts by weight of nano-zinc oxide, 3 parts of nano-titanium dioxide, 3 parts of ammonium dihydrogen phosphate, 4 parts of hydroxypropyltrimethylammonium chloride chitosan, and 28 parts of polyvinyl chloride , 5 parts of diethyl phthalate, 3 parts of chlorinated paraffin, 10 parts of polyamide resin, and 9 parts of polyisobutylene. The above components are mechanically mixed first, and mixed until the above-mentioned components are mixed evenly; (2 ) The materials in the step (1) after mechanically mixing uniformly are melted and extruded with a twin-screw extruder. It is divided into 3 sections: the temperature of the first section is 190°C, the temperature of the second section is 210°C, and the temperature of the third section is 230°C; (3) Wait for the material after twin-screw extrusion to cool before pelletizing, and after pelletizing, it is Prepared nano antibacterial plastics.

Abstract

The invention relates to a nano antimicrobial plastic and a preparation method thereof. The antimicrobial plastic comprises 2-6 parts of nano zinc oxide, 1-4 parts of nano titanium dioxide, 2-5 parts of ammonium dihydrogen phosphate, 2-5 parts of hydroxypropyl trimethyl ammonium chloride chitosan, 25-36 parts of polyvinyl chloride, 2-6 parts of diethyl phthalate, 2-5 parts of chlorinated paraffin wax, 8-18 parts of polyamide resin and 5-10 parts of polyisobutylene. The preparation method comprises the following steps: (1) mechanically mixing the components until the components are mixed uniformly; (2) carrying out melt extrusion on the mixture in the step (1) by using a double screw extruder; and (3) cooling the extruded material, and granulating to obtain the nano antimicrobial plastic.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a plastic and a preparation method thereof, in particular to a nano antibacterial plastic and a preparation method thereof. Background technique [0002] Plastic is one of the four major engineering materials, and has been widely used in the fields of industry, agriculture, construction, transportation, communication, medical treatment and daily life. Because plastic products are easy to be contaminated and breed a variety of microorganisms during processing and use, including pathogenic bacteria, they cause certain harm to people's health. With the improvement of people's awareness of environmental protection, more and more attention is paid to the pursuit of a healthy environment, and antibacterial plastics have emerged as the times require. In the use of antibacterial plastics, the first thing to do is to meet the requirements of plastics when they are used as basic materials. ...
