Abstract

The invention discloses a preparation method of a PET modified filler, a PET composite material and a preparation method of the PET composite material. The preparation method of the PET modified filler comprises the following steps: modifying fullerene to enable the surface of the fullerene to be modified with disulfydryl so as to obtain modified fullerene; mixing the modified fullerene with polyglycidyl methacrylate and acetone, reacting for 6-12 hours at the temperature of 40-60 DEG C, separating out solid substances after the reaction is finished, and drying to obtain microspheres; and calcining the microspheres at 600-800 DEG C for 4-6 hours to obtain the PET modified filler. The PET modified filler prepared by the method has relatively high porosity and specific surface area, and whenthe PET modified filler is used for modifying a PET material, the VOC performance of the PET material can be well improved.

Description

technical field [0001] The invention relates to the technical field of polymer modification, in particular to a preparation method of PET modified filler, a PET composite material and a preparation method thereof. Background technique [0002] VOC is a volatile organic compound, including alkanes, aromatics, olefins, halocarbons, esters, aldehydes, ketones and other organic compounds, most of which have an unpleasant special smell , and has certain toxicity, irritation, teratogenicity and carcinogenicity, especially benzene, toluene, formaldehyde, etc., which will cause great harm to human health. Common sources of VOC include plastic products prepared from synthetic resins, and the sources of VOC in plastic products are complex and extensive, for example, during the preparation of raw resins, catalysts, monomers, solvents, and Impurities and oligomers will remain in the resin and cannot be effectively removed by subsequent treatment; for example, in order to improve the ap...
