Abstract

The invention belongs to the technical field of plastic modification and processing, and in particular relates to a high-efficiency enhanced flame-retardant functional masterbatch which can be directly applied to injection molding processing of polypropylene products and a preparation method thereof; The mass percentage composition of A masterbatch is as follows: glass fiber 50.0-70.0 wt.%, high-flow polypropylene 15.0-35.0 wt.%, elastic ionomer 5.0-10.0 wt.%, atactic polypropylene 3.0 ~6.0 wt.%, maleic anhydride grafted polypropylene 1.0~3.0 wt.%, polytetrafluoroethylene powder 1.0~3.0 wt.%, antioxidant 0.1~0.3 wt.%; the functional masterbatch of the present invention has It is easy to disperse and process, and can be simply mixed with polypropylene resin according to the ratio and then injection molded.

Description

technical field [0001] The invention belongs to the technical field of plastic modification and processing, and in particular relates to a high-efficiency enhanced flame-retardant functional masterbatch which can be directly applied to injection molding processing of polypropylene products and a preparation method thereof. Background technique [0002] Using twin-screw extruder to implement melt blending is a traditional method for plastic modification. Using the high-efficiency and excellent mixing performance of co-rotating twin-screw extruders, thermoplastics and various modified additives can be continuously melt-blended and extruded After granulation, the prepared modified special material will be used again for injection or extrusion processing to form various products. This technical route not only effectively improves the physical and mechanical properties of plastic products such as strength, toughness, stiffness, creep resistance, and flexure resistance, but also e...
