Embodiment 1

[0017] Embodiment 1, a kind of preparation method of antibacterial toothbrush filament, forms by melt-spinning of nano-platinum chelate and thermoplastic polymer blending, wherein the weight percent of nano-platinum chelate is 0.1%. The platinum atoms in the nano-platinum-gold chelate form a porous cage structure.

[0018] Thermoplastic polymers include modified PBT filaments and modified PET filaments.

[0019] To increase friction, it can be mixed with some abrasives. These abrasives are one or more mixtures of calcium carbonate, silicon dioxide, calcium bicarbonate and aluminum hydroxide.

[0020] The present invention mixes dried nano-platinum gold chelate compound, thermoplastic polymer and abrasive material (not necessarily containing) evenly, draws silk according to the production method of known toothbrush silk, both can directly melt and plasticize and carry out spinning; also can use The screw is melted and granulated, and then drawn; it is also possible to make a ...

Embodiment 2

[0023] Embodiment 2, a preparation method of antibacterial toothbrush silk, formed by blending melt spinning of nano-platinum chelate and thermoplastic polymer, wherein the weight percentage of nano-platinum chelate is 0.4%.

[0024] Thermoplastic polymers include PTT (polytrimethylene terephthalate) and PEN (2,6- Ethylene naphthalate) and biodegradable polyester PLA (polylactic acid), PBS (polybutylene succinate) matrix materials, etc. These polyesters can be homopolymers or copolymers; in copolymers, other dibasic acids or their esters can be copolymerized, or they can be copolymerized with other diols; one of the polyesters can be used, or Two kinds of polyesters are used in combination.

[0025] To increase friction, it can be mixed with some abrasives. These abrasives are one or more mixtures of calcium carbonate, silicon dioxide, calcium bicarbonate and aluminum hydroxide.

[0026] Mix the dried nano-platinum gold chelate, thermoplastic polymer and abrasives (not nece...

Abstract

The invention provides a preparation method of antibacterial toothbrush monofilaments. The antibacterial toothbrush monofilaments are formed by blending, melting and spinning a nanometer platinum chelate and a thermoplastic polymer, wherein the weight percentage of the nanometer platinum chelate is 0.1-1%, platinum atoms in the nanometer platinum chelate are of a porous cage-shaped structure, and the thermoplastic polymer comprises modified PBT fiber filaments and modified PET fiber filaments. An antibacterial component adopted in the invention is the chelate of nanometer platinum and small-molecular organic acid, the nanometer platinum chelate and the thermoplastic polymer are blended and melted to prepare the antibacterial toothbrush monofilaments, so the toothbrush monofilaments are endowed with a long-acting antibacterial function.

Description

technical field [0001] The invention relates to the technical field of preparation of toothbrush filaments, in particular to a preparation method of antibacterial toothbrush filaments. Background technique [0002] Toothbrush is the requisite teeth-cleaning utensil in people's daily life, and its use makes people's quality of life have been greatly improved, especially has played very big effect aspect guaranteeing oral hygiene, preventing oral cavity disease. [0003] In order to ensure oral hygiene and prevent bad breath, dental caries, periodontitis and other oral inflammations, people produce various toothbrushes, but the focus of various improvements is to better remove the food residue attached to the teeth, and the toothbrush itself Oral recontamination caused by bacterial contamination in the population has rarely been studied. As we all know, the miscellaneous bacteria in the oral cavity are the main cause of dental diseases such as periodontitis and dental caries ...
