Problems solved by technology

[0006] The carriers of the above antibacterial materials are all artificially synthesized oxides or oxides. 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. Poor or no bacterial kill

example 1

[0053] Put magnesium tourmaline powder 100g, anatase nano-TiO 2 40g, rare earth oxide CeO 2 60g and 3.0 g of silver nitrate were prepared into a 60% slurry with deionized water. The prepared slurry was ground in a high-energy planetary ball mill at a speed of 350 rpm for 12 hours at a high speed. Dry the ground powder slurry at 100°C to remove the moisture in the slurry. Calcined at 600°C for 4 hours to make nano-TiO 2 , rare earth compounds and Ag ions are supported on tourmaline. Grinding on a high-energy planetary ball mill to a particle size of ≤5 μm, then grading and packaging to obtain the inorganic antibacterial agent.

example 2

[0055] Put magnesium tourmaline powder 100g, anatase nano-TiO 2 40g, rare earth complex CeO 2 +Ce(NO 3 ) 3 57g, 3.0g of silver nitrate, prepared into 60% slurry with deionized water. The prepared slurry was ground in a high-energy planetary ball mill at a speed of 350 rpm for 12 hours at a high speed. Dry the ground powder slurry at 150°C to remove the moisture in the slurry. Calcined at 600°C for 4 hours to make nano-TiO 2 , rare earth compounds and Ag ions are supported on tourmaline. Grinding on a high-energy planetary ball mill to a particle size of ≤5 μm, then grading and packaging to obtain the inorganic antibacterial agent.

example 3

[0057] Ferrite powder 140g, nano TiO 2 20g, rare earth oxide LaO 2 36g, 4.0g of zinc oxide, prepared into a 60% slurry with deionized water. The prepared slurry was ground in a high-energy planetary ball mill at a speed of 350 rpm for 24 hours at a high speed. Dry the ground powder slurry at 150°C to remove the moisture in the slurry. Calcined at 800°C for 4 hours to make nano-TiO 2 , rare earth compounds and zinc oxide loaded on tourmaline. Grinding on a high-energy planetary ball mill to a particle size of ≤5 μm, then grading and packaging to obtain the inorganic antibacterial agent.

Abstract

The present invention discloses a kind of inorganic disinfectant and its preparation process. The inorganic disinfectant consists of tourmaline 50-90 weight portions; photocatalytic material or nanometer TiO2, ZnO, CdO or SnO2, preferably nanometer anatase TiO 25-25 weight portions; compound RE salt or RE oxide of La, Ce, Nd, Sm, Pr, Eu or Y as the synergistic promoter 4-30 weight portions; and soluble metal oxide or metal salt 1-2 weight portions. The inorganic disinfectant has photocatalytic effect, negative ion releasing function, far infrared function and metal ion sterilization effect, so that it has synergistic disinfecting effect.

Description

【Technical field】 [0001] The invention relates to an inorganic antibacterial agent and a preparation method thereof, in particular to a tourmaline composite inorganic antibacterial agent and a preparation method thereof. 【Background technique】 [0002] At present, antibacterial materials at home and abroad are divided into three series: natural, organic and inorganic. However, due to its poor heat resistance, easy hydrolysis, and short service life, it cannot be applied to coatings, plastics, chemical fiber ceramics, and rubber products. Inorganic antibacterial materials are attracting more and more attention due to their broad-spectrum, heat resistance, safety, high efficiency and long-lasting antibacterial effects. Inorganic antibacterial materials can be divided into inorganic antibacterial agents with silver as the main agent, oxide photocatalytic systems Inorganic antibacterial agent and oxide natural ore inorganic antibacterial agent. [0003] Tourmaline is a ring-sh...
