Technical Field

The invention belongs to the technical field of processing of daily chemical articles, relates to a sterilization deodorant and a preparation method thereof, and particularly relates to a shell-based sterilization deodorant and a preparation method thereof.

Background

In the living environment of human beings, various microorganisms such as bacteria, viruses, and molds exist. When these microorganisms multiply on the clothes in large quantities, it is easy to cause various diseases. In addition, in the rainy season in the south and in a humid clothes drying room, the clothes are not easy to dry due to high air humidity, bacteria and mold are bred, and peculiar smell is generated in the clothes. Along with the improvement of living standard, people pay more attention to the cleanness and the comfort of clothes in life, so that how to effectively sterilize and deodorize the clothes of people becomes a research hotspot and a focus in the field of daily chemical industry at present.

The special disinfectant for clothes sold in the market at present is usually prepared by mixing a surfactant and a disinfectant, wherein the disinfectant is mainly polychlorinated compounds and hydrogen peroxide compounds, the disinfectant has the characteristics of pungent smell, fabric damage, inapplicability to colored clothes and the like, and if the disinfectant is not rinsed cleanly, the disinfectant has strong irritation to skin and mucous membranes and is harmful to body health. In addition, the sewage generated by washing the clothes by the clothes bactericide causes certain pollution to the environment after being discharged.

High temperature sterilization often causes damage to the laundry.

Therefore, a green and safe clothes sterilizing and deodorizing agent with good sterilizing performance is needed.

Disclosure of Invention

The invention aims to provide a safe, cheap and environment-friendly sterilization deodorant prepared by taking shells as raw materials, which has excellent sterilization and deodorization effects and overcomes the damage of the existing clothing sterilization agent to clothing, human bodies and the environment.

The invention provides a preparation method of a sterilizing deodorant, which comprises the following steps:

(a) performing permeation treatment on the shell by using a first surfactant to obtain a permeation-treated shell;

(b) performing microwave puffing treatment on the permeated shell to obtain a puffed shell;

(c) crushing the expanded shell to obtain a crushed shell;

(d) preparing a mixture of a second surfactant, the crushed shell and water to obtain the sterilizing deodorant solution.

The first surfactant functions to: improve the size of shell particles and the structure of holes, so that the shell particles are more uniform.

The microwave puffing treatment has the following effects: organic matters in the shells escape to form the biomass material with a special hole structure, and the puffing is a key step for preparing the material.

The second surfactant functions as: the micro-nano shell solution is mixed with a surfactant to enhance the washing effect.

The first surfactant is mainly used for regulating and controlling the surface structure in the shell modification process; the second surfactant is mainly a surfactant commonly used in the current detergent and is used for enhancing the washing performance.
