Abstract

The invention relates to graphene based super oil-absorbable and antibacterial oil-absorbable resin. The super oil-absorbable and antibacterial oil-absorbable resin is a porous material formed after expanded and foamed, and has a mutually communicated and developed pore structure, wherein the super oil-absorbable and antibacterial oil-absorbable resin takes super oil-absorbable resin as a matrix material, and modified porous graphene or a modified porous graphene antibacterial composition is combined inside the matrix material or / and between molecular structures of a surface layer of the matrix material. The graphene based super oil-absorbable and antibacterial oil-absorbable resin comprises the following components in parts by weight: 100 parts of an acrylate monomer, 0.5 to 5 parts of anemulsifier, 1 to 20 parts of modified porous graphene or a modified porous graphene antibacterial composition, 0.5 to 5 parts of a crosslinking agent, 0.05 to 2 parts of an initiator and a pore-forming agent. The modified porous graphene is formed by using polydimethylsiloxane to modify porous graphene through vapor deposition, and the modified porous graphene antibacterial composition is prepared by loading natural antibacterial agents in pores of the modified porous graphene.

Description

technical field [0001] The invention belongs to the research field of high oil-absorbing resin, in particular to a graphene-based high oil-absorbing and high antibacterial oil-absorbing resin. 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 transportatio...
