Wormwood PE functional master batch and application thereof in plastic products

Abstract

The invention relates to the technical field of PE master batches, in particular to a wormwood PE antibacterial master batch which is prepared from the following raw materials: 80-90% of PE resin slices, 5-15% of filler, 1-5% of dispersing agent, 1-3% of modifier and 3-10% of antibacterial active molecular nest, and the antibacterial active molecular nest is prepared from wormwood extract and titanium dioxide macromolecular nest matrix; the preparation method of the titanium dioxide macromolecular nest matrix comprises the following steps: preparing a precursor solution, volatilizing a solvent, and forming the titanium dioxide macromolecular nest matrix. The particle size of the antibacterial active molecular nest is 800-1000nm, the pore diameter is 8-15nm, and the specific surface area is650-800m<2> / g. The wormwood PE antibacterial master batch prepared by the method shows very good antibacterial property, and the staphylococcus aureus antibacterial rate, escherichia coli antibacterial rate and pseudomonas aeruginosa antibacterial rate are all greater than or equal to 99.9%.

Description

technical field [0001] The invention relates to the technical field of PE master batches, in particular to a mugwort PE functional master batch and its application in plastic products. Background technique [0002] PE masterbatch, the chemical name is polyethylene plastic, one of the most commonly used polymer materials, its performance is very stable, it is a non-toxic and environmentally friendly material, plastic products, plastic films, plastic bags, food bags, protective Films and electrostatic films are all made of this material. [0003] Patent CN201811455179.4 discloses a plant-derived PE masterbatch, which is mainly prepared by blending and melting PE masterbatch and modified motherwort extract; the PE masterbatch and the modified motherwort The mass ratio of the extract is 99:21; the plant-derived PE masterbatch prepared by the present invention has regular shape, no conjoined particles, no debris, particle size uniformity of 93.2-94.9%, and melt flow rate of 4.4-...

Problems solved by technology

[0005] The above patent is to directly add functional ingredients into the preparation process of PE masterbatch, and finally make a functional PE masterbatch. With the public's recognition of traditional Chinese medicine technology, many manufacturers in the industry adopt plants that will have the effect of traditional Chinese medicine. The extract is added to the preparation process of PE masterbatch to make PE masterbatch containing plant extracts to achieve the functionality of some plant extracts. However, due to the high temperature of PE masterbatch in melting, it is easy to add ingredients Changes occur under the action of high temperature, resulting in unstable quality of the prepared PE masterbatch, so the inventor thought of adding functional components to the PE masterbatch by porous adsorption, and the present invention is based on this
