Abstract

The invention discloses a preparation method of a long-acting antibacterial agent, and belongs to the technical field of an antibacterial agent. The preparation method comprises the following steps: stirring and mixing a cupric nitrate solution and a zinc nitrate solution according to the mass ratio of 1:1 to 1:2 to obtain mixed liquid; adding 10 to 20 parts by weight of tetrabutyl titanate into 50 to 60 parts by weight of mixed liquid dropwise while stirring to obtain mixed slurry; performing reduced-pressure concentration on the mixed slurry, calcining and grinding to obtain a pretreated mixed material; mixing 10 to 20 parts by weight of pretreated mixed material, 40 to 50 parts by weight of chitosan liquid, 20 to 30 parts of agar liquid, 10 to 20 parts of plant essential oil, 5 to 6 parts of a silane coupling agent and performing ultrasonic dispersion to obtain the long-acting antibacterial agent. The antibacterial agent provided by the invention has excellent sterilizing and antibacterial properties and can achieve the long-acting antibacterial effect.

Description

technical field [0001] The invention discloses a preparation method of a long-acting antibacterial agent, belonging to the technical field of antibacterial agents. Background technique [0002] Inorganic antibacterial agent refers to the method of physical adsorption or ion exchange adsorption, which loads silver, copper, zinc and other antibacterial metal ions on inorganic carriers such as zeolite, silica gel and hydroxyapatite, and releases the antibacterial metal ions slowly. Antibacterial A class of antibacterial materials. The oral environment is a bacterial environment with complex biochemical characteristics. Oral treatment is faced with the challenge of oral microorganisms. The antibacterial properties of oral materials affect the therapeutic effect to a certain extent. Silver-based inorganic antibacterial agents have the characteristics of broad antibacterial spectrum, safety and non-toxicity, and no drug resistance. In recent years, they have been applied to the r...
