Embodiment Construction

[0016] 1. Using the hematilite ore produced in Guangxi Resources as the main raw material, the raw ore is washed, crushed and processed to 550-600 mesh;

[0017] 2. Acidify with 1g of 0.1M hydrochloric acid 0.1M hydrochloric acid 40ml, stir and react the acidified stilbene with 20% sodium chloride under heat preservation for 2 hours, place it at room temperature for 2 hours, wash until neutral, and dry Sodium zeolite is obtained afterward;

[0018] 3. Add 1g of sodium zeolite, 5ml of 0.1M copper nitrate, 5ml of 0.1M zinc nitrate, and 10ml of 0.1M silver nitrate to the modified sodium zeolite in sequence, and stir and react under heat preservation for 2-3 hours. Place it for 2 hours, wash to neutrality, and dry to obtain a novel antibacterial agent loaded with copper-zinc-silver mixture.

Abstract

The invention discloses a preparation method for an antibacterial agent containing copper, silver and zinc antibacterial metal ions. The method comprises the following steps of: (1), levigating, crushing and processing epidesmine to 550 to 600 meshes; (2), acidulating each gram of epidesmine with 40ml of 0.1M hydrochloric acid, reacting the epidesmine and 20 percent of sodium chloride at a constant temperature for 2 hours with maintaining and stirring, standing the reaction product, washing the reaction product until the reaction product is neutral, and drying the reaction product; and (3), sequentially adding 1g of sodic zeolite, 5ml of 0.1M copper nitrate, 5ml of 0.1M zinc nitrate and 10ml of 0.1M silver nitrate into modified sodic zeolite, performing a reaction at a constant temperature for 2 to 3 hours with maintaining and stirring, standing the reaction product, washing the reaction product until the reaction product is neutral, and drying the reaction product to obtain the antibacterial agent. The epidesmine antibacterial agent has the advantages of strong antibiosis, high efficiency, heat resistance, good stability, high safety, good long-term effectiveness, wide antibacterial range and the like. Bacteria have no medicament resistance to the epidesmine antibacterial agent; the antibacterial effect is over 95 percent; and the cost is low.

Description

technical field [0001] The invention relates to an antibacterial agent, in particular to an antibacterial agent containing three antibacterial metal ions of copper, silver and zinc and a preparation method thereof. Background technique [0002] Stellerite is a mineral species in the pyroxene group, its chemical composition (%): SiO 2 58.76、Al 2 o 3 14.13, CaO8.80, K 2 O0.11, Na 2 O0.18, Fe 2 o 3 0.44, H 2 o + 16.87, H 2 o - 1.25, its chemical formula is (K 0.017 Na 0.042 Ca 1.73 ) 1.189 [Al 1.997Si7 .5i 7.05018 ]6.75H 2 O. Natural zeolite is a kind of hydrous alkali metal or alkaline earth metal aluminosilicate mineral, which is a framework silicate composed of silicon-oxygen tetrahedron and aluminum-oxygen tetrahedron. The oxygen atoms in the aluminum-oxygen tetrahedron have one valency and are not saturated, and the entire aluminum-oxygen tetrahedron is negatively charged, which is balanced with positively charged cations nearby. The open structure is fa...
