Problems solved by technology

The ion exchange method has the following problems: the amount of antibacterial metal ions held is limited, and any amount of holding can not be controlled; at the same time, a certain amount of antibacterial heavy metal ions are usually dissolved in the solution after ion exchange, and must be recycled in order not to pollute the environment. uneconomical
[0004] Some of the above-mentioned methods have limited antibacterial metal ions, and cannot control any amount of antibacterial metals, that is, they cannot support the necessary demand, so the antibacterial properties are low; In the glass phase, the antibacterial property is not high, or even loses the antibacterial property
Most of the carrier is artificially synthesized, and the cost is high; and the carrier material has a single component, it is difficult to bring into play the synergistic effect of the carrier and the antibacterial metal ion, and the antibacterial effect of the antibacterial metal ion cannot be fully brought into play.

Embodiment Construction

[0018] One, the preparation of inorganic antibacterial agent

[0019] 1. The carrier is a composite ceramic obtained by mixing apatite or apatite with one or more than two kinds of silicate minerals. The ratio of the composite ceramic is: the total amount of the selected silicate minerals is mixed The proportion of the total amount of ceramics is 50-90 wt%, and the proportion of apatite in the total amount of composite ceramics is 50-10 wt%.

[0020] 2. The ratio of the total weight of the antibacterial metal added to the carrier to the sum of the corresponding oxides and the above-mentioned carrier is:

[0021] The total weight of the carrier: the total weight of the antibacterial metal converted into the sum of the corresponding oxides = 100: 3 ~ 20

[0022] That is, the total weight of antibacterial metals converted into corresponding oxides is 3-20wt.% of the total weight of the carrier

[0023]Antibacterial metal raw materials can be selected from any one or more than t...

Abstract

An inorganic antibacterial agent used for preparing the antibacterial ceramics, paint, plastic film, fibres, or paper is composed of the composite ceramic as carrier prepared from the apatite or the mixture of apatite and natural silicate ore and the antibacterial metallic materials chosen from the salt, oxide, and monomer of metal chosen from Ag, Cu and Zn.

Description

Technical field: [0001] The invention relates to an inorganic antibacterial agent and its application, belonging to the technical field of inorganic antibacterial materials. Background technique: [0002] Most of the original inorganic antibacterial agents use zeolite, calcium phosphate, glass and other artificially synthesized inorganic materials with a layered or network structure as carriers, and metal ions such as silver, copper, and zinc as antibacterial active ingredients. In addition, there are also patents that propose the use of AL 2 o 3 , CaO, SiO 2 , ZrO 2 ,TiO 2 Inorganic antibacterial materials with good antibacterial properties have also been prepared with oxides such as Ag, Cu, Zn and other metal ions as carriers, and metal ions such as Ag, Cu, and Zn as antibacterial components. [0003] Metal ions such as Ag, Cu, and Zn are known to have antibacterial effects. The methods for supporting these metal ions on the carrier have been reported so far, includi...
