Embodiment 1

[0028] Embodiment 1: A polypropylene composition based on an organic hydrazide compound nucleating agent in this embodiment is carried out according to the following steps.

[0029] 100g of polypropylene, 0.06g of dibenzohydrazide sebacic acid, and 0.1g of antioxidants (1010 and 168) were uniformly mixed in a high-speed mixer for 3-8 minutes to obtain a mixed material. Put the mixed materials into a twin-screw extruder for extrusion and granulation to obtain the final composition.

Embodiment 2

[0030] Embodiment 2: Different from Embodiment 1, the quality of dibenzoylhydrazide sebacic acid used is 0.1 g.

Embodiment 3

[0031] Embodiment 3: Different from Embodiment 1, the quality of sebacic acid dibenzoylhydrazide used is 0.15g.

Abstract

The invention discloses a polypropylene composition based on an organic hydrazide compound nucleating agent. The polypropylene composition comprises the following raw material components in parts by weight: 100 parts of polypropylene, 0.001-10 parts of the organic hydrazide compound nucleating agent and 0.001-5 parts of an antioxidant. According to the polypropylene composition disclosed by the invention, a modifier with excellent high temperature resistance is introduced into the polypropylene composition, so that the performance of the polypropylene material is greatly improved. By adjustingthe various raw material components and ratios thereof, the polypropylene composition has good heat resistance and low temperature resistance and excellent mechanical property and also has antioxidant property and long service life. The polypropylene composition has excellent application prospects in the field of polypropylene application and has significances for developing high-performance polypropylene materials.

Description

technical field [0001] The invention belongs to the field of polymer material modification, in particular to a polypropylene composition based on an organic hydrazide compound nucleating agent. Background technique [0002] As a general-purpose thermoplastic resin, polypropylene has the advantages of low relative density, non-toxicity, heat resistance, corrosion resistance, excellent electrical insulation, high heat distortion temperature, easy processing and low price. Continuously develop new applications. However, the shortcomings of some of its properties also limit its application, such as its poor transparency, unsatisfactory strength, and poor electrical conductivity. In view of the above shortcomings, modifying it has become a research hotspot in recent years. There are many kinds of polypropylene nucleating agents, and different types of nucleating agents have different effects on polypropylene. Certain types of nucleating agents such as aryl carboxylates are nuc...
