Embodiment 1

[0019] 1. Diatomaceous earth purification

[0020] (1) Scrub and purify diatomite: Soak the original soil in water for 1-2 hours, then add water and sodium carbonate dispersant to make the slurry concentration reach 30%, and stir and scrub. Debris minerals and clay minerals are separated from diatoms, and sand-grade coarse soil, suspension-grade clay and selected diatomite are precipitated respectively, and the fine soil reaches more than 90% of amorphous silica; repeated scrubbing 3 times, each scrubbing time is about 20 to 30 minutes, the sedimentation time of sand grade coarse soil and suspension grade clay is 4 to 6 minutes each time, and the sedimentation time of the last selected diatomite is 2 to 4 hours; through scrubbing, detrital minerals and clay minerals are removed, silicon relative enrichment of algae, Si0 2 content increased, Al 2 0 3 , Fe 2 0 3 The content is reduced, and the content of diatom particles in diatomaceous earth reaches 92%.

[0025] Potential comparison before and after diatomite modification (mV):

[0026]

[0027] The main component of diatomaceous earth is hydrous non-quality silica. Under normal circumstances, the surface of diatomaceous earth particles is negatively charged. This is because some broken Si-O-Si bonds and unbroken Si-O-Si bonds on the surface of diatomite can chemically adsorb with water to form a surface adsorption layer with oyl negatively charged groups, and then through OH- Hydrogen bonds on the layer adsorb water molecules:

[0028] Looking at SiO on the surface of diatomaceous earth from another angle 2 Diatomaceous earth potential measurements before and after surface modification with molecules and water. After the organic modification treatment, the diatomite obtained a positive zeta potential value after testing, which indicated that the surface of the diatomite particle changed from the original negative charge to the positive charge, and confirmed the completio...

experiment example 2

[0032] The total number of Streptococcus mutans bacteria taken from the oral cavity was 5.2 × 10 3 / ml. The results of the diatomite test on the bacteria showed that the purified modified diatomite was effective on the bacterial liquid, but there were significant differences. Unmodified diatomite can remove part of the bacteria due to the entrapment of the pores, but the organically modified diatomite has a superior sterilization effect and can remove more than 99% of the bacteria. The test results show that the finer the particle size and the higher the sink potential value on the positively charged diatoms, the better the effect on the negatively charged bacterial liquid.

Abstract

The invention relates to the field of daily chemical toothpaste, and relates to a method for preparing toothpaste by using diatomite as an inorganic antibacterial filler. The method comprises the following steps: 1, purification of diatomite: (1) scrubbing purification, (2) roasting purification, and (3) grading extraction; and 2, diatomite modified finishing. The electricity of the surface of diatomite particles after modification finishing is changed into positive electricity from the original negative electricity, so as to confirm the completion of the surface charge modification process; the diatomite is used as a toothpaste raw material, is conducive to bacterial asphyxia and rupture, and achieves bacteriostatic and antibacterial purposes. Cell walls and cell membranes of bacteria inan oral cavity are negative, the positive charge of the diatomite inorganic antibacterial material can absorb a large number of bacteria having the surface with negative charge from a medium, ions released by minerals have inhibition and killing effects on the bacteria, and the antibacterial efficacy is a comprehensive result of the synergistic effect of electrostatic adsorption and ion sterilization.

Description

technical field [0001] The invention relates to the field of daily chemical toothpaste, that is, a method for making toothpaste by using diatomite as an inorganic antibacterial filler. Background technique [0002] In the prior art, diatomaceous earth is a new type of environmentally friendly material, which has strong adsorption capacity and other functions for harmful gases in the air, and is applied to various products and handicrafts because of its own unique functions. and other daily necessities. At present, the surface of diatomite purified, modified and produced at home and abroad is generally negatively charged, and its zeta potential value is negative. [0003] Inorganic antibacterial toothpaste refers to a toothpaste that adds inorganic antibacterial ingredients and uses physical methods to kill or inhibit bacteria. The cell walls and cell membranes of most harmful bacteria are negative, and metal cations such as gold, silver, and zinc can cause bacteria to suff...
