Degradable sanitary brush bristle and production method thereof

Abstract

The invention discloses a degradable sanitary brush bristle. The degradable sanitary brush bristle is prepared from the following raw materials in parts by weight: 85-95 parts of polyethylene, 15-20 parts of plant fiber, 0.4-0.8 part of a lubricant, 0.1-0.5 part of a coupling agent and 1-5 parts of an additive, wherein the additive comprises a foaming agent masterbatch. Through addition of the foaming agent masterbatch into polypropylene, the degradable sanitary brush bristle is good in heat stability, relatively high in tensile strength and impact strength and excellent in microwave adaptability, has the advantages of light weight, heat insulation, cushioning, anticorrosion, high specific strength, low price and the like, and has greatly improved mechanical properties and heat performance; the added coupling agent is easily oxidatively degraded, so that the degradable sanitary brush bristle has a fully-degradable function; through addition of the plant fiber, the degradable sanitary brush bristle has a good environment-friendly effect. The invention further discloses a production method of the degradable sanitary brush bristle.

Description

technical field [0001] The invention relates to the technical field of sanitation brush filaments, in particular to a degradable sanitation brush filament and a production method thereof. Background technique [0002] Sanitation brushes are brushes used for cleaning, mainly disc brushes or steel wire disc brushes, which are most commonly seen on street sweepers. With the vigorous development of urban cleaning work in our country, sanitation brushes have sprung up like mushrooms after rain. At present, the filaments of most sanitation brushes on the market are made of nylon, polyester, and polyolefin, which have a wide range of raw materials and high cost performance. After the sanitation brush is worn out, it is generally necessary to replace it with a new sanitation brush. Due to reasons such as excessive use and inadequate recycling, worn-out sanitation brush filaments will cause serious waste of energy resources and environmental pollution, and bring great harm to peopl...
