Problems solved by technology

[0003] At this stage, more products such as alcohol are used, because they are flammable and explosive products, and as a solvent with excellent performance, they will not only face the danger of fire during the spraying process, but also may cause the sprayed objects damage
Or the "84" disinfectant commonly used by people is used as a disinfection product commonly used in daily life, because it uses sodium hypochlorite with strong oxidizing properties to inactivate viruses and bacteria, and it needs to be over-diluted before spraying during use. Cause greater damage to human body or sprayed objects

preparation example Construction

[0034] In some preferred embodiments, the preparation method of acid-modified bentonite refers to the following steps:

[0035] 1) Add bentonite to the flask, then add sulfuric acid aqueous solution, add a condensing device, control the reaction temperature to 70-90°C, and heat in a water bath for 5-10 hours to obtain a mixture;

[0036] 2) centrifuge the mixture after the reaction in step 1), pour out the supernatant, add water to the precipitate in the centrifuge tube and stir to continue centrifugation until there is no sulfate ion in the supernatant (check with a saturated barium chloride aqueous solution until there is no precipitate generate);

[0037] 3) The precipitate obtained in step 2) is taken out, dried, ground, and set aside.

[0038] In some preferred embodiments, the molar concentration of the sulfuric acid aqueous solution in step 1) is 2-6 mol / L.

[0039] In some preferred embodiments, the molar concentration of the sulfuric acid aqueous solution described ...

Abstract

The invention belongs to the technical field of microorganism protection, and particularly relates to an organic-inorganic compound for long-acting microorganism protection and a preparation method thereof. According to the organic-inorganic compound for long-acting microorganism protection, the preparation raw materials at least comprise an inorganic antibacterial agent and / or an organic antibacterial agent; the inorganic antibacterial agent is an inorganic material loaded with metal particles. The prepared organic-inorganic compound for long-acting microorganism protection has a long-acting microorganism protection effect, and has an efficient inactivation effect on microorganisms such as viruses and bacteria; according to the prepared organic-inorganic compound, the compatibility between organic matter and inorganic matter is improved, the organic matter antibacterial agent and the inorganic matter antibacterial agent are further coated, migration of the organic antibacterial agent is avoided, the action time of the compound antibacterial agent is prolonged, and the slow release effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of microorganism protection, and more specifically relates to an organic-inorganic compound for long-term protection against microorganisms and a preparation method thereof. Background technique [0002] Facing the new situation of normalization of epidemic prevention at this stage, the requirements for antibacterial and antiviral products are getting higher and higher. From the inactivation effect of viruses and bacteria at the beginning, to the current requirement that the raw materials for antibacterial and antiviral products are healthy and safe, no danger occurs during use, and harmless to the human body and the environment. Evaluation criteria for viral products. [0003] At this stage, more products such as alcohol are used, because they are flammable and explosive products, and as a solvent with excellent performance, they will not only face the danger of fire during spraying, but also may cause the...
