Abstract

The invention belongs to the technical field of polymer materials, particularly relates to a high-gloss polypropylene resin composition, and further discloses a preparation method of the high-gloss polypropylene resin composition, and applications in preparation of high-gloss polypropylene composite materials. According to the present invention, by using the prepared high-gloss polypropylene matrix resin as the raw material and supplementing with the selected nucleating agent and the selected brightener, the anti-impact polypropylene resin with characteristics of good gloss, good impact resistance, good rigidity, high rigidity-toughness balance and low shrinkage rate is obtained while the shrinkage rate is significantly reduced, such that the assembly of injection molding parts and the substitutability of engineering plastics are improved, and the shortcomings in the prior art are effectively overcome.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-gloss polypropylene resin composition, and further discloses its preparation method and its application in preparing high-gloss polypropylene composite materials. Background technique [0002] Polypropylene (PP) is a semi-crystalline thermoplastic with high impact resistance, strong mechanical properties, resistance to various organic solvents and acid and alkali corrosion, and has low density, high strength, and easy recycling. It is one of the most common polymer materials. Polypropylene resin is a resin material based on a polypropylene matrix. It is a crystalline polymer with a regular structure. It is a light milky white pellet, odorless, non-toxic, and lightweight thermoplastic resin. It is also the lightest among general-purpose resins. kind. Polypropylene resin has good mechanical properties, good heat resistance, good chemical stability, an...
