Problems solved by technology

Since the whole is placed in the air, its surface is easy to deposit various dust in the air and bacteria harmful to the human body that may be contained in the droplets, but regular wiping and disinfection of it will not only bring inconvenience to work, study and life , can not achieve the effect of complete decontamination and sterilization
At present, the preparation method of antibacterial plastics is mainly made by adding a small amount of antibacterial agents and blending compounds. Most inorganic antibacterial agents are heavy metal ions, such as nano-silver, which are highly toxic to the human body and cause environmental pollution
The main varieties of organic antibacterial agents include aromatic aldehydes, ethyl vanillin compounds, quaternary ammonium salts and biguanides, etc. Organic antibacterial agents have poor temperature resistance, and there are dissolution and precipitation phenomena after long-term use

Embodiment 1

[0031] (1) Preparation of antibacterial masterbatch: firstly, the nano-silica NSG-MQAS grafted with polymer quaternary ammonium salt was treated with silane coupling agent KH550, and the amount of KH550 added was 2% of the mass of inorganic nano-antibacterial agent. Based on the total mass of inorganic nano-antibacterial agent and carrier resin, 25% nano-SiO 2 , 75% PA6 carrier resin and 0.5% EBS dispersant are mixed evenly at high speed, and finally extruded and granulated in a twin-screw extruder to obtain antibacterial masterbatch. The temperature of each section of extrusion is 220°C-250°C.

Abstract

The invention discloses an antibacterial masterbatch, nano antibacterial super-tough plastic added with an antibacterial masterbatch and preparation and an application of the plastic and relates to the technical field of high molecular materials. The nano antibacterial super-tough plastic is characterized by being prepared from the following raw materials in parts by weight through blending and extruding: 70-93 parts of resin, 2-10 parts of antibacterial masterbatch, 5-20 parts of a flexibilizer, 0.1-1.0 part of an antioxidant and 0.2-1.0 part of a lubricant. The preparation method comprises the following steps: firstly, preparing the antibacterial masterbatch, then, weighing the raw materials in proportion, adding into a high speed mixer and mixing for 2-10 minutes; and then, extruding and granulating the obtained mixture through a twin-screw extruder to obtain the nano antibacterial super-tough plastic. The nano antibacterial super-tough plastic disclosed by the invention has an efficient, lasting, broad-spectrum and safe antibacterial effect, can be applied to preparation of spectacle frames and can satisfy the requirements on characteristics of the spectacle frames such as great elasticity, strong toughness and difficulty in breakage.

Description

technical field [0001] The invention relates to an antibacterial masterbatch, a nanometer antibacterial super-tough plastic added with the antibacterial masterbatch and its preparation and application, belonging to the technical field of polymer materials. Background technique [0002] In daily life, a considerable number of harmful bacteria exist and multiply on the surface of plastic products, and cause various diseases through contact. As people's awareness of health and environmental protection continues to increase, there is a demand for "antibacterial and sterilizing" plastic parts that are frequently touched in daily life. There are many spectacle frames on the market, the main reason is to improve the material, but there are few studies on the antibacterial function. Since the whole is placed in the air, its surface is easy to deposit various dust in the air and bacteria harmful to the human body that may be contained in the droplets, but regular wiping and disinfec...
