Abstract

The invention discloses a plastic toughening agent, a reinforced and toughened polypropylene plastic and a preparation method of the reinforced and toughened polypropylene plastic. The plastic toughening agent is prepared from the following raw materials: dimethyl azodiisobutyrate, benzene, ethylene-butyl acrylate-glycidyl methacrylate, a monomer X, a monomer Y and a benzene solution of 2-mercaptoethanol, and has a good toughening effect.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a plastic toughening agent, a reinforced and toughened polypropylene plastic and a preparation method thereof. Background technique [0002] Plastic is a kind of high molecular polymer, which has the characteristics of easy processing and molding, light weight, good light transmission, good mechanical properties, durability, and corrosion resistance; however, some plastics have high notch sensitivity and low impact strength, which restricts plastics. In some fields of application, adding toughening agents to change the toughness of plastics, thereby improving the impact resistance of plastics is the most commonly used method. [0003] Tougheners are a class of additives that can reduce the brittleness of plastics and improve the impact resistance of plastics. They can be divided into two types: active tougheners and inactive elastic tougheners; The active group of the matrix re...
