Abstract

The invention relates to a method for preparing a graphene high-oil absorption resin. The method comprises the following steps: 1, putting modified porous graphene or modified porous graphene antibacterial composition into deionized water, and performing ultrasonic dispersion for 1-24 hours so as to obtain a modified porous graphene suspension; 2, stirring deionized water and an emulsifier in a reaction container, sufficiently dissolving, and adding an acrylic monomer so as to obtain a stable emulsion; 3, putting the modified porous graphene suspension into the emulsion in the step 2, performing continuous stirring emulsification for 30-60 minutes, further adding a chemical cross-linking agent and a pore-forming agent, and continuously stirring for 10-30 minutes; 4, heating to 40-70 DEG C,performing a reaction for 2-20 hours with an initiator so as to obtain porous high-oil absorption resin gel; 5, pelletizing the porous high-oil absorption resin gel, and drying in an oven at 105-180DEG C till a constant weight, so as to obtain the graphene high-oil absorption resin.

Description

technical field [0001] The invention belongs to the research field of high oil-absorbing resins, in particular to a preparation method of graphene high oil-absorbing resins. Background technique [0002] Super Oil-Absorbable Resin (SOAR) is a new type of functional polymer material and a general term for a class of polymers with high oil absorption properties. [0003] High oil-absorbing resin is a new type of polymer material developed in recent years for waste oil treatment. It is a self-swelling functional polymer material with both adsorption and absorption functions. It has high oil absorption ratio and can absorb many types of oil. With high selectivity and good oil retention under pressure conditions, it can not only replace traditional oil-absorbing materials for waste oil treatment, but also be suitable for the treatment of oil spills at sea and recovery of oil slicks on water surfaces. [0004] In the process of oil exploration and transportation, oil leakage inci...
