Abstract

The invention discloses a production method for degradable sanitation brush bristles. The production method for the degradable sanitation brush bristles comprises the following steps: preparation of raw materials of the sanitation brush bristles, wherein the raw materials comprise 10-20 parts of chitosan, 40-58 parts of a polylactic acid solution, 10-25 parts of propyl lactate, 5-13 parts of plantfibers, 3-8 parts of sodium stearate, 15-30 parts of modified starch, 2-5 parts of a coupling agent and 0.3-0.7 parts of a lubricant; mixing of the raw materials: mixing the chitosan, the polylacticacid solution, the propyl lactate, the plant fibers, sodium stearate, the modified starch, the coupling agent and the lubricant in the step 1, and then performing fusing to obtain a liquid mixture; shaping of the liquid mixture into bristles: preparing the precursor bristles from the liquid mixture by a drawbench, and then shaping the precursor bristles to obtain first preselected bristles after shaping; screening, cleaning and drying of the first preselected bristles to obtain a preselected bristle group; preparing the sanitation brush bristle clusters from the preselected bristle group to obtain the sanitation brush bristles. The brush bristles prepared with the preparation method are degradable and low in environment pollution.

Description

technical field [0001] The invention relates to sanitation-related fields, in particular to a method for producing degradable sanitation brush filaments. Background technique [0002] Sanitation brush: Drill holes at a certain angle (∠135°) on the cut PP disc, then use the cut flat steel wire, PP brush wire, or nylon wire to fold in half and insert them in series. The brush is installed in the municipal sanitation vehicle For street cleaning / snow removal, etc. Disc brushes or steel wire disc brushes installed in municipal sanitation vehicles for street cleaning are representative types of sanitation brushes. The products include sweeping machine roller brush, tablet roller combination sweeping brush, roller sweeping machine brush, sweeping machine brush, square road sweeping brush, round branch road sweeping brush, sewage treatment brush, floor washing machine brush, computer Car washer brushes, etc. [0003] After the sanitation brush is worn out, it is generally necessa...
