Abstract

The invention discloses a polypropylene modified material for improving impact strength and a preparation method thereof. The modified material is prepared by the following components according to a weight percentage: 70 wt% of a polymer matrix, 1-20 wt% of a rigid particle reinforcing agent, 5-28 wt% of a compatibilizer, 0.1-5 wt% of a stabilizer, and 0-5 wt% of other additives. The method is capable of improving production efficiency of the polypropylene material, so the polypropylene modified material and the preparation method thereof are worth popularizing.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polypropylene modified material with improved impact strength and a preparation method thereof. Background technique [0002] my country has a vast territory, and the climate varies greatly. The use of polymer materials not only needs to consider the normal temperature environment, but also the low temperature environment, especially thermoplastic resins such as PP, PVC, nylon, etc. used in agriculture, construction, medical treatment, transportation and other fields. Therefore, It is extremely important and urgent to effectively improve the low-temperature toughness of these materials and obtain thermoplastic resin materials that can meet the requirements of most northern regions and alpine regions. [0003] Compared with low-temperature and ultra-low-temperature toughening, the ordinary toughening of polymers in 1950 was mainly based on rubber-toughened thermoplastic...
