The principle of the invention is illustrated as follows:
the adopted organic compounds are all water-soluble materials;
glacial acetic acid can be used as an acidity regulator, acidulant, pickling agent, flavoring agent, perfume, etc., and can lower the pH below that required for optimal growth of microorganisms;
the urea can react with acid to generate salt with hydrolysis, and can effectively denature protein, especially can effectively destroy protein combined by non-covalent bond;
the benzenesulfonic acid can acidify a deep stratum, and compared with hydrochloric acid, the benzenesulfonic acid (and mixed aryl sulfonic acid) has the advantages of long effective period, low corrosivity and safe use;
under the condition of weak acidity (pH value is about 6.5), urotropine can be hydrolyzed into hippuric acid and formaldehyde, the formaldehyde can denature pathogen protein to play a nonspecific antibacterial effect, and the formaldehyde concentration has a sterilization or bacteriostasis effect according to different pH values;
the acidity of p-toluenesulfonic acid is one million times of that of benzoic acid, and the p-toluenesulfonic acid is soluble in water and used for synthesizing medicines, pesticides, stabilizers of polymerization reactions and catalysts of organic synthesis (esters and the like);
the dodecyl benzene sulfonic acid generates heat when being diluted by water, has the functions of emulsification, dispersion, decontamination and the like, has certain corrosivity, is used for preparing various liquid and solid detergents, is stable in an acid solution, and has good washing performance;
the polyamide is a general term for thermoplastic resin containing repeated amide groups on a molecular main chain, has the most outstanding advantages that the wear resistance is higher than that of all other fibers, and the polyamide is used for fixing materials when being used for preparing a deodorant and is convenient to use in the later period;
inorganic ions can generate chemical reaction or chemical adsorption with pyridine, indole, mercaptan, thioether, dimethyl disulfide, hydrogen sulfide, ammonia gas and heterocyclic compounds containing sulfur or nitrogen, odor molecules are enclosed, a water-soluble ion group is formed, and the generated malodorous gas is quickly fixed in water, so that the aim of permanent deodorization is fulfilled.
The deodorization principle is as follows: the biological deodorant mainly utilizes odor molecules which mostly have amino, carboxyl, hydroxyl, sulfydryl, thioether, disulfide, ether bond or heterocyclic rings containing nitrogen, sulfur and oxygen and derivatives thereof, wherein the odor molecules all contain abundant lone pair electrons, have electronegativity and have the tendency of adsorbing positive charges, the positive charges adsorb anions to form large ion groups to be dissolved in water, thereby achieving the deodorization effect, decomposed small molecular compounds such as hydrogen sulfide, ammonia, indole and the like also have the function of rapidly combining with iron ions, urea, polyamide, urotropine and the like to generate chemical reaction or hydrogen bond combination, organic macromolecules such as polystyrene sulfonic acid, polyamide and the like also play a role of wrapping the odor molecules or specific groups thereof, and the odor molecules or the specific groups thereof are not easy to volatilize and also play a role of water retention because the organic macromolecules are not easy to volatilize
