Abstract

The invention discloses an extrusion grade polypropylene material with high heat resistance and a method for preparing the extrusion grade polypropylene material. The extrusion grade polypropylene material comprises polypropylene, mineral filling, toughening agents, lubricants, antioxidants, complex heat-resistant agents and light stability complex agents. The polypropylene, the mineral filling, the toughening agents, the lubricants, the antioxidants, the complex heat-resistant agents and the light stability complex agents are mixed, extruded and granulated to obtain the extrusion grade polypropylene material. The extrusion grade polypropylene material and the method have the advantages that the complex heat-resistant agents are used, and accordingly the extrusion grade polypropylene material is high in heat aging resistance and light aging resistance; the excellent mechanical properties of the extrusion grade polypropylene material can be guaranteed, and application of the extrusion grade polypropylene material in the aspect of liquid delivery and storage systems of chemical pipelines further can be expanded.

Description

technical field [0001] The invention belongs to the technical field of polypropylene materials, and in particular relates to an extrusion-grade high heat-resistant polypropylene material and a preparation method thereof. Background technique [0002] With the wide application of polypropylene pipes in machinery manufacturing, petrochemical industry and various agricultural industries, in recent years, it has expanded to more fields. However, due to the slightly poor impact strength, aging resistance and heat resistance of polypropylene materials, there are certain limitations in the pipe market. However, polypropylene has a large proportion of raw materials and low raw material cost. After modification, its excellent top performance has made it grow into the most widely used plastic product after polyethylene. [0003] Over the years, we have been committed to improving polypropylene materials, overcoming problems such as aging resistance and poor heat resistance, and gradu...
