Technical Field
The invention relates to the technical field of cleaning toothbrushes, in particular to a soft-bristle toothbrush capable of being efficiently cleaned and a preparation method thereof.
Background
The toothbrush is a cleaning article, is a handle type brush and is used for adding toothpaste on the brush and then repeatedly brushing all parts of teeth. The toothbrush is an oral cavity cleaning tool which is necessary in daily life, and the bristles are selected to be moderate in hardness or slightly soft. However, it is noted that too soft bristles tend to be unclean. Conventional toothbrushes are generally straight-handled and are relatively easy to use. The curved handle can reach deep into the mouth where brushing is difficult. The resilient handle is said to prevent damage to the gums due to excessive force of the toothbrush against the gums. The anti-slip handle prevents the toothbrush from slipping off during tooth brushing. The toothbrush has long service life, and the bristles accumulate bacteria, which is not beneficial to oral health.
In the prior art, the toothbrush has limited cleaning effect and poor antibacterial effect, and is not beneficial to oral health.

The antibacterial performance of the soft-bristle toothbrush is improved by adding the antibacterial agent into the raw materials, the water and oxygen resistance of the soft-bristle toothbrush is improved by adding the nano particles, and the wear resistance of the soft-bristle toothbrush is improved by adding the inorganic filler. The whole soft bristle toothbrush is integrally formed, and can be recycled as resin waste when replacement is needed. The nano particles and the inorganic filler can also increase the overall mechanical strength, so that the brush bristles can have stronger brushing force under the condition of smaller diameter, and are more beneficial to cleaning. The soft-bristle toothbrush finally prepared has the advantages of good antibacterial performance, good barrier performance, wear resistance, long service life and recyclability.
In one embodiment of the invention, the soft-bristle toothbrush comprises the following components in parts by weight: 100 parts of high molecular polymer material, 2 parts of nano particles, 5 parts of inorganic filler, 2 parts of antibacterial agent, 4 parts of coupling agent, 3 parts of antioxidant and 2 parts of plasticizer.
