Problems solved by technology

The existing patent CN103073834 discloses a toothbrush made of biodegradable synthetic materials. The toothbrush made of biodegradable synthetic materials is obtained by using cellulose, polymer plasticizers, plastic raw materials, titanium dioxide, and additives as synthetic materials. Toothbrushes use more chemical additives and restricted polymer plasticizers that are harmful to the human body, have poor biocompatibility, and are unhealthy and unsafe for the human body

Abstract

The invention provides a degradable toothbrush main material with a self-cleaning function. The toothbrush main material is prepared by the following steps of mixing chitosan, a radix notoginseng extract, a honeysuckle extract, carboxymethyl chitosan, a nanomaterial, biotin, lysine and collagen to prepare a mixed solution; adding a degradable resin material, and carrying out a cross-linking reaction under the action of a cross-linking agent to prepare a textile material; adding polybutylene terephthalate, a lubricant, an antioxidant and polyethylene glycol 200, and performing fusing, dissolving, extruding and cooling to obtain textile particles; and carrying out electrostatic spinning. According to the invention, nanoparticles are adopted to cooperate with the radix notoginseng extract andthe honeysuckle extract, so that the plasticity and elasticity of the material are enhanced, and the self-cleaning, bacteriostasis and efficient decontamination effects of the toothbrush main material are realized; and therefore, the toothbrush main material ensures the oral health of people and is suitable for commercial popularization.

Description

technical field [0001] The invention belongs to the technical field of functional synthetic fibers, in particular to a degradable and self-cleaning toothbrush main material. Background technique [0002] Toothbrush is an indispensable daily consumable for human life, and its usage is extremely large. At present, the commonly used toothbrush filaments are mostly made of nylon (PA), polybutylene terephthalate (PBT), polypropylene (PP) and other polymer materials, and the toothbrush handles are mostly made of AS, PS, PP and TPU, etc. Polymer Materials. These materials are non-degradable materials that can exist in nature for hundreds or thousands of years. While these materials facilitate people's lives, they also cause great pollution to nature. With the original higher requirements for environmental protection, biodegradable materials have gradually entered people's daily life. [0003] Biodegradable materials are a class of materials that can undergo a series of physical...
