Abstract

The invention provides high oil absorption resin. The high oil absorption resin is prepared form the following raw materials in parts by weight: 1.6-9.4 parts of rapeseed meal, 90.7-96.9 parts of a graft monomer, 0.3-1.1 parts of an initiator and 0.01-0.13 part of a crosslinking agent. The invention also provides a preparation method of the high oil absorption resin. The preparation method comprises the following step: with the rapeseed meal as a substrate, MMA and BA as monomers and BPO as the initiator, carrying out graft copolymerization to synthesize RSM-g-P (MMA-co-BA) high oil absorption resin successfully. The high oil absorption resin has the inherent lipophilic performance of RSM and is also added with the characteristics of BA and MMA after crosslinking, and thus the oil absorption performance of the high oil absorption resin is greatly improved.

Description

technical field [0001] The invention relates to a high oil-absorbing resin and a preparation method thereof. Background technique [0002] Swellable oil-absorbing resin refers to a polymer with a low degree of cross-linking obtained by cross-linking and polymerizing lipophilic monomers. Due to the unique physical and chemical cross-linking structure in the oil-absorbing resin, the swellable oil-absorbing resin has a super oil-absorbing capacity, so it is widely used in the fields of industrial waste oil, sea oil spills, and oil field exploitation. Studies have shown that the chemical cross-linking structure in the swelling oil-absorbing resin has strong oil binding force, but it has the disadvantages of difficult entry and exit of oil molecules, low oil absorption ratio, and poor reversibility of oil absorption and release; the physical cross-linking structure mainly relies on molecular The spatial structure formed by intertwining chains can reduce the steric resistance dur...
