Abstract

The invention discloses a toothbrush handle polypropylene material and a preparation material thereof. The toothbrush handle polypropylene material is composed of, by weight, 88-96% of polypropylene,2-10% of ethylene propylene rubber, 0.1-0.5% of nanoscale powder rubber and 1.5-1.9% of color masterbatch. Polypropylene and the ethylene propylene rubber are adopted as main raw materials, and the nanoscale powder rubber is added, so that rigidity of the toothbrush handle polypropylene material is improved while toughness of the same is met, rigidity index of the toothbrush handle polypropylene material is improved by 10-20%, and rigidity-toughness balance is excellent. The toothbrush handle polypropylene material is suitable for manufacturing high-end toothbrush handle products and is simplein manufacturing process.

Description

technical field [0001] The invention relates to a polypropylene material, in particular to a toothbrush handle polypropylene material and a preparation method thereof. Background technique [0002] At present, toothbrush handles on the market are all made by injection molding. The handle of the toothbrush should be long and straight, and the middle part of the handle should be slightly bent upwards, with a certain degree of elasticity and a fixed fulcrum. The handle of the toothbrush is usually in a straight line with the head of the toothbrush, and the force on the teeth is uniform and convenient for vertical brushing. However, the handle of some special toothbrushes is designed with a certain curvature. The shape of the toothbrush handle is easy to grasp. The brush handle should preferably have non-slip rubber, which should be comfortable to hold, moderate in length, and have appropriate elasticity to buffer the excessive force when brushing teeth, so that the toothbrush...
