Title:
RECYCLED MATERIAL BASED ON IN-SITU COMPATIBILIZATION AND CHAIN EXTENSION AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/093705
Kind Code:
A1
Abstract:
A recycled material based on in-situ compatibilization and chain extension. The recycled material is mainly prepared from the following raw materials in parts by mass: 30-70 parts of waste HIPS; 30-70 parts of waste PP; 2-6 parts of POE; 0.1-0.4 part of an alkylation reaction catalyst; 0.1-0.3 part of a co-catalyst; and 2-8 parts of a macromolecular chain extender. The recycled material uses waste HIPS and waste PP as raw materials, two types of chemical modifiers are used in a segmented and matched mode, and in-situ compatibilization and chain extension repairing effects are achieved by means of grafting and chain extension reaction, respectively, so that the recycled material having excellent comprehensive performance is prepared by directly performing in-situ modification on the waste HIPS and the waste PP, and a high-valued attribute is also embodied while waste resources are fully used. Further disclosed is a preparation method for the recycled material based on in-situ compatibilization and chain extension.
