Description
Technical field
The present invention relates to oil absorption material and preparation method thereof, more particularly, relate to quick porous high-oil-absorption resin of binary and preparation method thereof.
Background technology
In recent years, along with the fast development of world industry and improving constantly of people's living standard, the transport of oil and all kinds of oil product and use have become a part for the modern life.But oil carrier leakage accident, the problems such as the discharge of industrial oily waste water are also on the rise thereupon.Therefore, the R and D of high-quality oil absorption material have become one of great research topic.
Initial people utilize the porous materials such as cotton, sponge, clay to carry out oil suction.These traditional oil absorption materials have easy to use, price is low, the advantage such as biodegradable, but its oil number is low, oil-water selectivity is poor, and the shortcomings such as pressurized leakage of oil greatly limit its application in oiliness sewage treatment.People utilized the hydrophobic material of organic synthesis as fibers such as polyethylene, polypropylene, polyethylene terephthalates afterwards, and oil sucting pad and the oil suction of preparation definite shape are glued, and its oil-water selectivity is greatly improved, but Oil keeping can be still poor.High oil absorbing resin is a kind of new functional macromolecule material for wastewater treatment that success is in recent years developed, and its oil suction multiplying power is high, oil-water selectivity good, overcomes the shortcoming of traditional oil absorption material, is a kind of material having Development volue.
High oil-absorbing resin be with lipophilicity monomer by appropriately crosslinked and formed three-dimensional netted superpolymer, the solvation mainly through the lipophilic group on macromolecular chain and oil molecule makes resin generation swelling action.Because resin inside is containing tridimensional network, resin only occurs swelling and can not dissolve, and the oil molecule therefore entering into resin inside will be wrapped in macromolecular three-dimensional net structure, and such resin is just provided with oil suction and protects effect of oil.And high oil absorbing resin structure is similar to High hydrophilous resin, there is certain micropore inside, has good chemical stability, swelling rate is fast, oil-water selectivity good, is easy to advantages such as reclaiming, aftertreatment is simple.Therefore high oil absorbing resin tool in environment protection has been widely used.The domestic and international research primary limitation to high oil absorbing resin is improving in the influence factor and polymerization process condition etc. of polyreaction at present, the high oil absorbing resin developed is general lower to the oil suction multiplying power of oil product, and swelling rate is comparatively slow, generally need just can reach capacity for twenties hours oil number.There is the problems such as formula is complicated, oil suction multiplying power is low, cost is high, swelling rate is slow in the high oil absorbing resin in currently available technology, is therefore difficult to the needs meeting oily water treatment aspect.
Summary of the invention
The object of the invention is to overcome the problem that current high oil absorbing resin oil suction multiplying power is low and swelling rate is slow, the preparation method of the quick porous high-oil-absorption resin of binary is provided.The present invention for monomer, prepares high oil absorbing resin by suspension polymerization with vinylbenzene and methyl acrylic ester.In building-up process, introduce pore-creating agent, form a kind of low cross-linking superpolymer of loose porous.The introducing of pore-creating agent not only solves the slow problem of swelling rate, but also significantly improves oil suction multiplying power.
