Embodiment Construction

[0050] The embodiments of the present invention will be described in detail below with reference to the examples, but those skilled in the art will understand that the following examples are only used to illustrate the present invention and should not be regarded as limiting the scope of the present invention. If the specific conditions are not indicated in the examples, it is carried out according to the conventional conditions or the conditions suggested by the manufacturer. The used raw medicines, reagents or instruments that do not indicate the manufacturer are all conventional products that can be purchased from the market or can be prepared according to the existing technology. The invention stably adsorbs or coats metal oxides in the organic framework formed by chitosan to obtain metal salt-chitosan two-phase antibacterial particles, and solves a series of problems such as inconspicuous antibacterial effect and non-environmental protection of the existing antibacterial p...

Abstract

The invention relates to antibacterial particles and a preparation method thereof. An antibacterial particle comprises a polysaccharide phase and a metal oxide phase, the polysaccharide phase has an organic framework, and the metal oxide phase is located in the organic framework; the polysaccharide phase is chitosan. The preparation method of the antibacterial particles comprises the following steps: dissolving metal salt and chitosan in a mixed solvent of organic acid and water to form a chitosan-metal salt dissolving solution; adding a pore-foaming agent and a cross-linking agent into the chitosan-metal salt dissolving solution to form chitosan-metal salt gel; preparing the chitosan-metal salt gel into a plurality of chitosan-metal salt gel particles; the chitosan-metal salt gel particles are placed in a treating agent to be soaked; and drying the chitosan-metal salt gel particles soaked in the treating agent. A metal salt-chitosan two-phase antibacterial system is used for achieving a good antibacterial effect, and meanwhile the particles are more environmentally friendly through the characteristics that the dosage of metal ions is reduced and chitosan can be naturally degraded and is non-toxic and harmless.

Description

technical field [0001] The invention relates to the technical field of antibacterial products, in particular to an antibacterial particle and a preparation method thereof. Background technique [0002] Antibacterial materials are a class of functional materials with bactericidal and antibacterial properties, which mainly achieve antibacterial effects by adding antibacterial agents. Among them, antibacterial particles are often used in the field of washing due to their advantages of easy storage and transportation. Antibacterial particles are mainly divided into three categories: natural antibacterial particles, organic antibacterial particles and inorganic antibacterial particles. [0003] Natural antibacterial particles are safe, environmentally friendly and have good antibacterial properties, but due to their poor heat resistance, short efficacy period and limited production conditions, it is difficult to achieve industrialization. [0004] Organic antibacterial agents u...
