Abstract

The invention relates to a polypropylene-based polymer material, which is prepared through the steps of mixing nickel nitrate, magnesium nitrate and carclazyte evenly and then sintering in a muffle furnace at 1050 DEG C for 2h to obtain a solid; crushing the solid, and filtering through an 800-mesh sieve, wherein screen underflow is taken as a composite filler; melting and mixing polypropylene with the molecular weight of 13,000-16,000, phenoxyacetic acid, the composite filler, acrylic ester and benzoguanamine to prepare a polypropylene composition; and carrying out extrusion molding on the polypropylene composition through extrusion equipment and treating at 80 DEG C for 10min to prepare the polypropylene-based polymer material. The raw materials in the preparation method are readily available, the preparation process is simple and controllable, only normal operation is needed by post-treatment equipment and industrialization is easy to implement.

Description

technical field [0001] The invention belongs to the technical field of polymers, in particular to a polypropylene-based polymer material. Background technique [0002] As one of the most conventional plastics, polypropylene can be seen everywhere in military, civil, and engineering. Polypropylene-based polymer materials prepared from polypropylene particles have low density, are odorless, tasteless, and non-toxic, and are food-grade plastics. In line with national health standards, in addition to being used in machinery and engineering, it is also widely used in the food field. Light weight and lower processing temperature than metal are important advantages of plastic rod applications; however, due to the inherent defects of plastic products, the flame retardancy, mechanical properties, and heat resistance of polypropylene-based polymer materials need to be improved and kept stable. In the production process of plastic rods, the plastic particles are first melted in the ex...
