Embodiment Construction

[0017] The present invention provides, in order to make the object, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] The invention discloses a nanocomposite plastic master batch, wherein nano-silver material is added to the plastic master batch to enhance the antibacterial performance of the plastic master batch, wherein the nano-silver is in the form of silver ions. The antibacterial enhancement order of metal is cadmium, zinc, nickel, lead, copper, silver, mercury. Although the antibacterial property of mercury is the strongest, considering safety and antibacterial effect, the preferred nano-silver of the present invention is as antibacterial material, more The choice is to add nano-silver material with a weight ratio of 5% i...

Abstract

The invention discloses a nanometer composite antibiotic master batch. The antibiotic plastic master batch is prepared through the following steps: forming an active carbon layer on the surface of a semi-finished plastic master batch in the preparation process of the plastic master batch, adsorbing nanosilver to the active carbon layer, and drying in a drying machine at 60-90DEG C. The nanometer composite antibiotic plastic master batch has the advantages of wide antibiotic spectrum, lasting antibiotic effect, strong antibiosis, good thermal stability, high temperature resistance, difficult color change, good compatibility and dispersibility, and no change of original processing technologies of plastics.

Description

technical field [0001] The invention relates to the field of nanotechnology, in particular to a nanocomposite antibacterial plastic masterbatch. Background technique [0002] At present, plastic products play a very important role in people's daily life and industrial and agricultural production. In order to make plastic products more widely used, people often add antibacterial agents to the plastic masterbatches used to prepare plastic products to obtain antibacterial plastic products. The antibacterial agents used in antibacterial plastics can be classified into inorganic, organic and natural. Organic antibacterial agents have poor toxicological safety and poor chemical stability, which will lead to drug resistance of microorganisms; they are easy to migrate and have poor durability, especially poor heat resistance. Many antibacterial plastics are easy to decompose at high processing temperatures. Natural antibacterial agents are easy to carbonize and decompose at high t...
