| titleOfInvention | Polyether modified PBAT degradable plastic and preparation method thereof |
| abstract | The invention provides a polyether modified PBAT degradable plastic and a preparation method thereof, relating to the technical field of material modification, wherein the preparation method specifically comprises the following steps: (1) mixing terephthalic acid and adipic acid, adding 1, 4-butanediol, mixing, uniformly stirring to obtain a mixture A, adding magnesium oxide and tetrabutyl titanate, heating and reacting to obtain a material A; (2) and adding tetrahydrofuran-propylene oxide copolyol, polytetrahydrofuran glycol, 1- (3-dimethylaminopropyl) -3-ethylcarbodiimide and 4-dimethylaminopyridine into the material A, reacting, extruding and granulating to obtain the polyether modified PBAT degradable plastic. The method comprises the step of adding materials including the polyether with the specific molecular weight, so that the improvement of the catalytic efficiency can be effectively promoted, and the mechanical property of the product is improved. |
