AI Technical Summary

Problems solved by technology

In addition to EPDM rubber, materials such as SBS, SEBS, SIS, and EVA are also good tougheners for polypropylene resins. However, there are few reports on related dynamic vulcanized elastomers. The molecular compatibility of propylene is poor. CN1247682C reports a method for preparing elastomers by dynamic vulcanization of SIS, SBS or SEPS and PP. In this method, if the compatibility of elastomer molecules and polypropylene molecules is considered, adding Sexual additives will further improve material properties

Abstract

The invention discloses a block polypropylene toughening and modifying compatibilizer. The block polypropylene toughening and modifying compatibilizer is prepared by performing esterification on the following raw materials in percentage by weight in a solvent: 47.5-49.75% of carboxylic-anhydride-grafted polypropylene, 47.5-49.75% of carboxylic-anhydride-grafted toughening elastomer and 0.5-5% of glycol derivatives, wherein the glycol derivatives are polyethylene glycol or polyethylene glycol derivatives. The invention further discloses a preparation method and application of the block polypropylene toughening and modifying compatibilizer. The block polypropylene toughening and modifying compatibilizer disclosed by the invention is capable of enhancing compatibility between polypropylene resin and corresponding elastomer as well as improving performance of polypropylene toughening elastomer materials.

Description

technical field [0001] The invention belongs to the technical field of toughened and modified compatibilizers, in particular to a novel compatibilizer for preparing polypropylene toughened and modified composite materials. Background technique [0002] Polypropylene resin has the advantages of good mechanical properties, low density, non-toxicity, corrosion resistance and easy processing and molding, and is widely used in building materials, home appliances, automobiles, pipes, daily necessities and other fields. However, in some fields that require special requirements, such as high toughness, high rigidity, electrical conductivity, etc., the performance of general-purpose polypropylene resin is difficult to meet the requirements, and the polypropylene resin needs to be modified accordingly. In the field of high-toughness products, such as automobile bumpers, it is necessary to add toughening agents to the extrusion of polypropylene base materials to improve toughness. In t...
