NOVELTY - Environment-friendly special-shaped brush preparation technique comprises preparing functional filler by weighing seaweed carbon fiber, conductive fiber, carboxymethyl cellulose and lignin fiber, mixing uniformly, carrying out ion beam irradiation treatment, and finishing to obtain first mixture; placing graphene in corona discharge instrument for corona treatment and taking out; putting first mixture and graphene after corona treatment in bead mill for crushing, and sieving to obtain functional filler; weighing functional filler, natural rubber, propylene glycol, propylene glycol fatty acid ester, solid rubber, calcium silicate, linoleic acid and water; preparing brush wire by putting raw materials in micro-jet high pressure homogenizer for high pressure homogenizing treatment, putting mixture in internal mixer for heating to molten state, pulling and drawing wire, heating and shaping, and cutting to obtain brush wire; and embedding brush wire into carrier. USE - The method is used for preparing environment-friendly special-shaped brush. ADVANTAGE - The method can homogenize and fuse matrix component and endow special brush antistatic. The brush has high mechanical property. DETAILED DESCRIPTION - Environment-friendly special-shaped brush preparation technique comprises preparing functional filler by weighing 20-30 pts. wt. seaweed carbon fiber, 9-13 pts. wt. conductive fiber, 11-15 pts. wt. carboxymethyl cellulose and 7-11 pts. wt. lignin fiber, mixing uniformly, carrying out ion beam irradiation treatment, and finishing to obtain first mixture; placing graphene in corona discharge instrument for corona treatment and taking out for further use; putting first mixture and graphene after corona treatment at weight ratio of 8-9:1 in bead mill for crushing, and sieving to obtain functional filler; weighing 13-17 pts. wt. functional filler, 75-95 pts. wt. natural rubber, 3-5 pts. wt. propylene glycol, 5-8 pts. wt. propylene glycol fatty acid ester, 7-10 pts. wt. solid rubber, 3-5 pts. wt. calcium silicate, 10-12 pts. wt. linoleic acid and 30-40 pts. wt. water; preparing brush wire by putting raw materials in micro-jet high pressure homogenizer for high pressure homogenizing treatment, putting mixture in internal mixer for heating to molten state, pulling and drawing wire, heating and shaping, and cutting to obtain brush wire; and embedding brush wire into carrier.
