High-transparency high-flowability toughened polypropylene material and preparation method thereof

Abstract

The invention relates to a high-transparency high-flowability toughened polypropylene material and a preparation method thereof. The high-transparency high-flowability toughened polypropylene material contains the following raw materials by weight percent: 20-70 percent of polypropylene, 10-30 percent of m-LLPE, 5-10 percent of ethylene-octene copolymer, 3-10 percent of compatilizer, 5-15 percent of SEBS, 5-30 percent of white oil and 0.1-0.5 percent of antioxygen. The preparation method comprises that the raw materials are weighed according to the weight proportions; the SEBS and the white oil are put into a high-speed mixer and are evenly mixed first, other raw materials are added and are mixed for 2-5 minutes, and the obtained mixture is discharged; and the evenly mixed raw materials are put into a screw extruder and are extruded for granulation. The toughened polypropylene material has the advantages that the mechanical property is excellent, and the flowability and the transparency are better than the flowability and the transparency of common PP toughened materials. The toughened polypropylene material can be used to manufacture high-transparency high-toughness tools and functional parts of shells of instruments and gauges.

Description

technical field [0001] The invention relates to a high-transparency, high-fluidity and toughening polypropylene material and a preparation method thereof. The material can be used to make tools with high transparency and high toughness requirements, and functional parts of instruments and instrument shells, belonging to the technical field of polypropylene toughening. Background technique [0002] The usual polypropylene toughening materials mainly include EPDM, POE, etc. When these materials are blended with polypropylene, because EPDM and POE will affect the crystallization of polypropylene, and the fluidity of the toughening agent is very poor, resulting in the prepared The polypropylene toughened material does not have a transparent effect, and the flowability of the material is poor. Contents of the invention [0003] The object of the present invention is to provide a highly transparent and high-fluidity toughened polypropylene material and a preparation method there...
