Abstract

The invention discloses a Preparation method and application of an antibacterial, anti-adhesion, acid-resistant, antifouling and hydrophobic tooth protectant. The tooth protectant comprises a photoresponse antibacterial agent, nanoparticles, a hydrophobic modifier, a hydrophobic adhesive and an absolute ethyl alcohol solvent, wherein the hydrophobic modifier is used for carrying out hydrophobic modification on the nanoparticles, and the sprayable photoresponse antibacterial anti-adhesion acid-resistant antifouling super-hydrophobic tooth protectant is obtained by mixing the photoresponse antibacterial agent and the hydrophobic adhesive with the modified nanoparticles. A protective film formed after the spraying agent is sprayed on teeth and cured has photo-responsiveness, antibacterial and anti-adhesion properties, acid-resistant and antifouling properties and super-hydrophobic properties, food residues and bacteria can be effectively prevented from being adhered to the teeth, the antibacterial property can be further improved under the excitation of a 500-750nm LED visible light source, bacteria which are luckily adhered to the teeth can be killed in time, and meanwhile, the effects of degrading pigments and whitening are achieved. The method has the advantages of low requirements on production equipment, safe and convenient production process, simplicity in use, high practicability, capability of realizing large-scale production and suitability for the public.

Description

technical field [0001] The invention relates to the technical field of preparation technology of superhydrophobic coatings, in particular to a preparation method and application of an antibacterial, anti-adhesion, acid-resistant, anti-fouling, anti-fouling and hydrophobic tooth protector. Background technique [0002] With the continuous development and progress of society and the continuous improvement of living standards, more and more people pay attention to dental health problems. People are no longer satisfied with finding a dentist for toothache and simply brushing their teeth. People's ideas have gradually changed from treating dental diseases to regular dental care care. The vast majority of dental care methods are to remove food residues on the teeth in time to avoid bad breath, prevent teeth from turning yellow and black, and prevent bacteria from colonizing and growing on the surface of teeth to produce acid and cause caries, gingivitis and periodontitis, etc. . ...
