High-lustrousness material filled with modified polypropylene and preparation method thereof

Abstract

The invention discloses a high-lustrousness material filled with modified polypropylene, which comprises the following ingredients in percentage by weight: 70 to 90 of polypropylene, 4 to 15 of inorganic mineral fillers, 4 to 15 of calcium carbonate crystal whiskers, 0.1 to 1 of antioxidizers and 0 to 2 of other accessory agents. The invention has the advantages that 1, the invention adopts the high-lustrousness homopolymerized polypropylene as basic resin, and simultaneously adopts the calcium carbonate crystal whiskers which is helpful for the improvement of the surface laser to improve therigidity of the material, so the material can obtain high lustrousness and high rigidity at the same time; and 2, both the lustrousness and the rigidity of the material are improved to a certain degree through the compounding of the inorganic minerals and the calcium carbonate crystal whiskers, and the integral performance of the material is more balanced.

Description

technical field [0001] The invention relates to a filled modified polypropylene material with high gloss, and provides a preparation method of the polypropylene material. The material has the characteristics of high gloss, high rigidity and high heat resistance. Background technique [0002] As a general-purpose plastic, polypropylene is widely used in automobiles, home appliances and other industries. However, the rigidity and heat resistance of ordinary polypropylene resin are not high, and it is often difficult to meet various practical applications in various industries. Filling polypropylene with inorganic fillers to obtain low-cost and high-performance modified polypropylene materials is one of the most effective and economical ways to obtain high-performance polymer composite materials. People usually use mineral filling methods to improve the rigidity, heat resistance and dimensional stability of polypropylene materials. However, when the polypropylene is filled wi...

Application No. 00117199 discloses a high-gloss anti-aging polypropylene material for household appliances. This method uses a nucleating agent to promote the crystallization of polypropylene. However, with the progress of the polypropylene synthesis process, the crystallization performance of high-crystalline polypropylene is better than that of Use a nucleating agent; the Chinese patent application number 200610027888.3 has also announced a high-gloss impact-resistant filled modified polypropylene and its production method and application. It mainly uses polyolefin elastomers to improve the toughness of the material, but this also makes the material Both the glossiness and rigidity of the
