Abstract

The invention discloses a modifier for regenerating and processing hybrid waste plastic net / wire / thread materials, wherein the modifier contains the following components by weight: 1-3 parts of maleic anhydride, 2-3 parts of chlorinated polyethylene, and 3-5 parts of ethylene-vinyl acetate copolymer; and a preparation process of the modifier comprises: uniformly mixing the raw materials of the modifier into a high speed mixer, discharging and cooling for standby application. A usage method of the modifier for regenerating and processing hybrid waste plastic net / wire / thread materials has the following steps of: (1) classifying the obtained hybrid waste plastic net / wire / thread materials; (2) crushing, washing, dehydrating, drying, dehumidifying and detecting the hybrid waste plastic net / wire / thread materials; (3) uniformly mixing the modifier for regenerating and processing hybrid waste plastic net / wire / thread materials and the hybrid waste material raw materials, heating to generate grafting reaction, and cooling for standby application; and (4) granulating. The modifier has characteristics of simple technology, convenient operation, low cost and no pollution, and can be widely used in a generating and processing field of waste plastic nets / wires / threads.

Description

technical field [0001] The invention relates to a waste plastic recycling processing aid and an application method, in particular to a mixed waste plastic net / filament / wire material regeneration processing modifier and a using method. Background technique [0002] As we all know, the traditional method of recycling waste plastics is generally to reheat and plasticize waste plastics to make them enter a viscous flow state and then pelletize them for utilization. Due to the high uneven heating of waste plastics, this method depolymerizes the macromolecular chains, loses some of the original compatibility of waste plastics, and greatly reduces its physical properties, and heating under the condition of moisture will make the plastics Further aging and degradation, therefore, the waste plastic recycled plastic processed by this method is of poor quality. In recent years, although some enterprises and researchers have added modifiers to waste plastics, the mechanical properties ...
