Production method of Ag-HA and applications used as anti-bacteria agent

Abstract

The invention relates to a method for preparing hydroxyapatite loading Ag (HAP-Ag) and an application as an antimicrobial. The preparation method thereof mainly includes the following steps: hydrothermal reaction step, that is adding the hydroxyapatite to the mixed solution of the silver nitrate and the cerous nitrate, wherein the concentration of both the silver nitrate and the cerous nitrate is 0.01mol / L-0.2mol / L, the reaction temperature is 30 DEG C - 60 DEG C and the reaction time is 2-5 hours; the steps of depositing, sucking and filtrating, drying, and grinding. The novel preparation method of the HAP-Ag and the application as the antimicrobial have remarkable antimicrobial products with high durability, long-term antimicrobial effect, convenient usage, no toxin and harmlessness, so as to be applicable to pregnant women and babies.

Description

technical field [0001] The invention relates to a method for manufacturing an antibacterial agent, in particular to a method for manufacturing a silver-loaded hydroxyapatite antibacterial agent (HAP-Ag Antibacterial substances). Background technique [0002] At present, due to the effects of many factors such as physics, biochemistry and harmful microorganisms, various items in life are prone to breed bacteria and even produce toxic substances, which seriously affect the health of people, especially pregnant women and infants. With the progress of society and the improvement of people's living standards, the requirements for the quality of life are getting higher and higher, and the safety and quality of items have also become issues of concern. The majority of consumers demand more convenient and sterile items. Increasingly, antibacterial articles have become a new research hotspot in the field of antibacterial. Wherein, the antibacterial protective film formed by immersin...

Problems solved by technology

[0004] Although the above-mentioned Chinese medicine antibacterial liquid detergent can provide the user with an antibacterial agent that is convenient and has sterilizing effect, it is indeed progressive, but it is found that it also has some disadvantages in actual use, resulting in this traditional Chinese medicine antibacterial liquid detergent. In practical applications, the best use effect has not been achieved, and its shortcomings can be summarized as follows:

[0005] 1. First of all, it is mainly used for washing, and its scope of application is small

[0006] 2. In addition, the antibacterial liquid detergent of traditional Chinese medicine can not change the antibacterial function of the substance within 50 times of washing, but its antibacterial persistence is not strong. Once it is washed more than 50 times, its antibacterial function will be significantly reduced

[0007] 3. Furthermore, when the antibacterial agent is sprayed on the surface of the article, the corresponding surface properties, polarity, surface roughness, surface oxygen, and percentage of nitrogen atoms of the article will all affect the bonding strength between the object and the antibacterial agent, thus affecting the antibacterial performance

[0008] This shows that above-mentioned existing antibacterial agent obviously still has inconvenience and defect in composition, method and use, and urgently needs to be further improved
