Synthesis Of Super Oil-absorbable Resin And Study On Its Oil-absorption Properties

With difficulty in petroleum exploitation increasing since twentith century,most of our oil fields produced fluid is in stage of high water cut.Oil-field produced water is likely to increase daily.On the other hand,discharge of factory oil-wastewater and leak of oil tanker,oilcan and petroleum extraction destroy the balance of nature.How to get rid of the oil pollution is a topic that grows daily in interest and major significant importance.Super Oil-Absorbable Resin is a kind of crosslinking functional polymer material.Super Oil-Absorbable Resin is a new kind of self-swelling-absothing material with with many strong points,recycle easily,deposit easily and brilliant prospects.Super Oil-Absorbable Resin not only be uesd in the field of environmental protection,but also be used in fine chemical,pharmaceutical,industrial,agriculture,and other areas.Super Oil-Absorbable Resin has an even broader prospect for development.The Super Oil-Absorbable Resin with new kind of self-swelling-absothing has been prepared by suspension polymerization.The effects of monomer ratio,initiator amount,crosslinker types,synthesis temperature,mixing speed,oil-water ratio and amount,porogen amount on oil-absorptive rate,oil absorbency and oil relention were discussed.The optimum conditions are as follows:m(tetradecyl methacrylate ester):m(propyl methacrylate)is 1:4,synthesis temperature is 80?,reaction time is 5 h,oil-water ratio is 1:8,the amount of the dispersing agent is 3.0%of the monomer by weight,the amount of the initiator is 0.5%of the monomer by weight,the amount of the crosslinking agent is 1.5%of the monomer by weight,the amount of the porogen is 50%of the monomer by weight,the porogen could improve the oil slick absorbing of the SOAR.
