Abstract

The invention discloses a polypropylene material and a preparing method thereof. The polypropylene material is prepared from 50-100 parts of polypropylene, 5-35 parts of an ethylene-octylene copolymer, 3-10 parts of POE-grafted maleic anhydride, 3-10 parts of a synergistic coloring reinforcing agent, 0.5-5 parts of coloring master batches, 0.1-0.5 part of an antioxidant and 0.1-1.0 part of a lubricating agent through mixing and melt extrusion pelleting; the coloring master batches are prepared from ultralow-viscosity polypropylene, titanium dioxide, phthalo blue, phthalein green, titanium yellow powder, carbon black and iron oxide red through mixing and extrusion pelleting. According to the polypropylene material and the preparing method thereof, the low-viscosity polypropylene is introduced, and the whole liquidity and processability of the polypropylene material are guaranteed; through the cooperation effect of the coloring master batches and the synergistic coloring reinforcing agent, the whole material has good coloring capacity and good toner dispersity while the stability of the mechanical property of the material is kept.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer with a density of only 0.90-0.91g / cm 3 , is currently one of the lightest varieties of all plastics. It is particularly stable to water, the water absorption rate in water is only 0.01%, and the molecular weight is about 80,000-150,000. With the continuous development of its application, people put forward higher and more specific requirements for polypropylene. For example, people have more pursuit of product colors, which requires processed materials to have various bright appearances. At present, people mainly add toner to the material to achieve the color requirements of the material, but because the toner is dispersed very unevenly in the reinforcement system, the color of the material is...
