Problems solved by technology

[0003] 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.

Embodiment 1

[0025] This embodiment provides an antibacterial masterbatch, which includes the following components in parts by weight: 3 parts of silver-loaded antibacterial agent, 2 parts of dispersant, 1 part of nano-ultraviolet absorber, 3 parts of nano-titanium dioxide, and 35 parts of carrier resin.

[0026] Wherein the nano-titanium dioxide is porous titanium dioxide, the nano-ultraviolet absorber is a benzotriazole-type ultraviolet absorber, and the silver-loaded antibacterial agent is AG300 antibacterial agent of Japan East Asia Synthetic Chemical Company.

[0027] The preparation process of the above antibacterial masterbatch is as follows: Weigh each component by weight, first add porous titanium dioxide and nano-ultraviolet absorber to a high-speed mixer and mix evenly, then add silver-loaded antibacterial agent, dispersant and carrier to the high-speed mixer The resin is evenly stirred, and finally the evenly stirred semi-finished product is extruded, drawn, and pelletized with ...

Abstract

The invention belongs to the technical field of plastic materials, and discloses an antibacterial master batch and antibacterial plastic, the antibacterial master batch comprises the following components by weight: 1-5 parts of a silver-loaded antibacterial agent, 1-5 parts of a dispersant, 1-3 parts of a nano ultraviolet light absorber, 1-5 parts of nano titanium dioxide, and 25-45 parts of carrier resin. The antibacterial plastic comprises a resin raw material and antibacterial master batches. And the antibacterial master batch accounts for 0.3-1% of the total mass of the antibacterial plastic. The antibacterial master batch has a good antibacterial effect no matter in a dark and humid environment or in a sunshine irradiation environment. Meanwhile, the antibacterial master batch also has an anti-ultraviolet effect. The antibacterial master batch with an extremely low proportion is added into the resin raw materials, so that the antibacterial plastic product has excellent antibacterial effect and still has excellent antibacterial performance after being washed and soaked in warm water.

Description

technical field [0001] The invention belongs to the technical field of plastic materials, and in particular relates to an antibacterial masterbatch and antibacterial plastic. Background technique [0002] 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 added at present are generally based on organic antibacterial agents and inorganic antibacterial agents. [0003] 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 temperatures. Inorganic antibacterial agents usually ...
