Embodiment 1
[0046] S1. Preparation of graphene masterbatch: 60% of 80nm biomass graphene powder prepared by hydrothermal carbonization of biomass resources by weight percentage, 25% of dispersant Pluronic P123 and 15% of Surfactant alcohol ether sulfate is mixed, through stirring, dispersing, obtain graphene slurry; Then use 15% graphene slurry to blend with 65% pure terephthalic acid PTA, 20% ethylene glycol EG to obtain mixed solution, again Add the catalyst sodium aluminate and stir evenly, and then introduce it into the reaction kettle for esterification reaction. The amount of the catalyst added is 1% of the weight of the mixed solution; , final shrinkage, casting, cooling, granulation, and drying to obtain graphene masterbatch.
