ABS (Acrylonitrile Butadiene Styrene) and PA (Polyamide) dewatering master batch and preparation method thereof

Номер: CN0101942127B
Автор: XICHEN WANG, QIXUAN HUANG, XIANGYANG HUANG, WANG XICHEN, HUANG QIXUAN, HUANG XIANGYANG
Принадлежит:

The invention provides an ABS (Acrylonitrile Butadiene Styrene) and PA (Polyamide) dewatering master batch and a preparation method thereof. The dewatering master batch mainly comprises a dewatering agent, an inorganic filler, a surfactant, a processing aid and carrier resin by a weight ratio of (50-80):(20-40):(1-5):(5-10):(15-30). The preparation method of the dewatering master batch comprises the following steps of: firstly, carrying out surface activation treatment on the dewatering agent and the inorganic filler in a high-speed stirrer by using the surfactant; then adding the processing aid and the carrier resin and uniformly mixing; and finally, granulating by using a double-screw extruder. The dewatering master batch prepared by the invention is convenient to use, has good dewatering effect and does not influence the appearance and the mechanical strength of ABS and PA products.
