Problems solved by technology

Most of them use chemical materials, the cost is still high
[0005] In addition, in real life, in rural areas, many farmers burn straw every year during wheat harvest and autumn harvest, which seriously pollutes the environment.

Abstract

The invention provides a full-degradable toothbrush handle and a machining process of the full-degradable toothbrush handle, wherein the full-degradable toothbrush handle provided by the invention is made of a full-natural matter, enables a handle body to have higher strength and can be fully degraded within a short period. The full-degradable toothbrush handle comprises the following components in parts by weight of 10-30 parts of starch, 40-60 parts of plant fibers and 10-25 parts of biogum liquid. According to the full-degradable toothbrush handle provided by the invention, the starch and the plant fibers form a brush handle part of a toothbrush by adding biogum through a pouring / calendaring (using equipment, such as an injection molding machine or an extruding machine) process; a toothbrush head is formed by carrying out injection molding on materials, such as normal PP (Propene Polymer) / PS (Poly Styrene); and the toothbrush head and the toothbrush handle are assembled to form the entire toothbrush, so that the flocking tension of the toothbrush is consistent with the flocking tension of a normal toothbrush; the degradation degree of the toothbrush handle is 100%; and the weight of the toothbrush head only occupies about 3-5% of the entire product, and the degradation rate of the entire product reaches 95-97%.

Description

technical field [0001] The invention relates to the technical field of fully degradable natural composition processing, in particular to a toothbrush handle raw material that can be fully degraded and integrated into the living environment and a preparation method thereof. Background technique [0002] Toothbrushes currently on the market are basically injection molded from non-degradable PP / PS and other materials. The progress of modern life has prompted two basic use cycles for the toothbrush, a product that people need to use every day. One is used for a long time, such as a conventional toothbrush with a lower limit of 3 weeks, and the other is disposable. Disposable toothbrushes for internal use. This amount of utilization causes a large number of toothbrushes to be discarded in society. The toothbrush body (handle) made of the above-mentioned polymer materials is difficult to degrade and will seriously pollute our environment. [0003] Application date: 2009-11-25, a...
