Abstract

The invention belongs to the field of polymer materials and provides a polypropylene composite material for a spinning tube and a preparation method of the polypropylene composite material. The composite material comprises the following components in percentage by weight: 54.5-73.5% of polypropylene, 20-35% of glass fiber, 5-8% of active filler, 0.6-0.8% of a dispersing agent, 0.5-1.0% of a coupling agent, 0.2-0.3% of a nucleating agent and 0.2-0.4% of an antioxidant. The preparation method comprises the following steps: weighting each component according to the percentage by weight, uniformly mixing each weighted component to obtain a mixture, adding the obtained mixture into a twin screw extruder and carrying out melt extruding and granulating to obtain the polypropylene composite material for the spinning tube. The polypropylene composite material has the characteristics of high heat resistance, high strength, difficulty in deformation, no floating fiber, good surface finishing degree and the like and can be widely used in the manufacturing of various spinning tubes.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polypropylene composite material for spinning tubes and a preparation method thereof. Background technique [0002] With the development of the cotton textile industry, the material of the spinning bobbin has gradually developed from the original wood to plastic. Since the promotion of the plastic bobbin in the 1970s, it has become popular because of its ease of processing, high-speed rotation stability, firmness, and long service life. The unique advantages are quickly recognized and popularized in the textile industry. [0003] Common raw materials for textile plastic bobbins are: polypropylene (PP), polycarbonate (PC), nylon (PA), acrylonitrile-butadiene-styrene copolymer (ABS), etc., choose PC and ABS, It is because it has good strength and toughness, good overall performance, stable size, and the price of PP is more competitive, but general PP has problems such ...
