The technical problems firstly established by the inventor for modifying bentonite are as follows: how to modify bentonite to make it have good antibacterial property. The specific invention thought of the inventor is as follows: (1) the bentonite is purified to remove impurities, so that the performance of the bentonite can be effectively improved. (2) In the process of modifying the bentonite, the technical means used by the inventor, namely sulfuric acid acidification, is not adopted, the production process is simple, the cost is saved, and the method is more environment-friendly. (3) The plant antibacterial agent is glycyrrhizin/cinnamaldehyde to modify bentonite, so that the antibacterial performance of the bentonite is improved. (4) Further, during the modification process, polyhexamethylene biguanide hydrochloride is added, the polyhexamethylene biguanide hydrochloride and the plant antibacterial agent glycyrrhizin/cinnamaldehyde are synchronously adsorbed on the surfaces of negatively charged bacteria to prevent the bacteria from dividing and breeding, and the polyhexamethylene biguanide hydrochloride and the plant antibacterial agent glycyrrhizin/cinnamaldehyde adsorbed on the surfaces of the bacteria act on cytoplasm through transmembrane transport, so that the selective permeability of cell membranes is changed, the cell metabolism is damaged, and the bacteria are killed.

In the bentonite modification process, polyhexamethylene biguanide hydrochloride is added, the polyhexamethylene biguanide hydrochloride and the plant antibacterial agent glycyrrhizin/cinnamaldehyde are synchronously adsorbed on the surface of the negatively charged bacteria to prevent the bacteria from dividing and propagating, and the polyhexamethylene biguanide hydrochloride and the plant antibacterial agent glycyrrhizin/cinnamaldehyde which are adsorbed on the surface of the bacteria act on cytoplasm through transmembrane transport, so that the selective permeability of a cell membrane is changed, the cell metabolism is damaged, and the bacteria are killed.
By comparison of examples 3-5, it can be seen that although dimethyl-3-hydroxypropyl-methyl ethoxylate does not possess antibacterial properties by itself, it can assist polyhexamethylene biguanide hydrochloride in enhancing its antibacterial microbicidal effect. In order to achieve similar antibacterial effect, the addition of dimethyl-3-hydroxypropyl-methyl ethoxylate can reduce the addition of polyhexamethylene biguanide hydrochloride, and the raw material cost of dimethyl-3-hydroxypropyl-methyl ethoxylate is far lower than that of polyhexamethylene biguanide hydrochloride, so that the raw material cost in the formula is greatly reduced.
Furthermore, dioleoyl ethyl hydroxyethyl methyl ammonium methyl sulfate has excellent flexibility and antibacterial performance, and has a synergistic effect with modified bentonite, so that the antibacterial and softening effects are superior.
