Abstract
The preparation method that the invention discloses a kind of porous high-oil-absorption resin, by methacrylic acid cetyl ester, deionized water, emulsifying agent is 300 ~ 400rpm stirring and emulsifying 65-70min at 50 DEG C；It is subsequently adding porogen, cross-linking agent, continues high-speed stirred 30 minutes, ultrasonic 3 ~ 10min de-soak after stirring；Stating then up in emulsion and pass into nitrogen 15 minutes, seal and magnetic agitation, react 5 hours at 65 DEG C, obtain spongy polymerizate, after reaction terminates, elimination gel, gained emulsion to constant weight, obtains high oil suction acrylic resin in 80 DEG C of oven dryings。Reaction process is simple, and quickly, finished product oil absorbency is high, to the oil suction multiplying power of toluene and kerosene all more than 9 times。
Description
Technical field
The preparation method that the present invention relates to a kind of porous high-oil-absorption resin。
Background technology
High oil absorption resin adsorption material can adsorb oil products, bigger oil suction multiplying power, swelling rate faster because of it, obtains development and application widely in recent years, and prospect is very wide。
High oil-absorbing resin is the low crosslinking degree polymer that lipophile monomer is constituted。Intermolecular have three-dimensional cross-linked network structure, there is certain micropore inside, solvation by Intramolecular oil base segment and oil molecule, making polymer segment stretch, after macromolecule is fully swelling, macromolecular chain is stretched over to a certain degree, slowly bounce back, there is elastic recovery force, be finally reached thermodynamical equilibrium, make resin expand and act on and oil suction。
More there is formula complexity in the high oil-absorbing resin in currently available technology, cost is high, the problems such as oil suction multiplying power is low, it is difficult to meets and processes requirement。
Summary of the invention
For solving the problems referred to above, the preparation method that the invention provides a kind of porous high-oil-absorption resin, its preparation process is:
(1) by methacrylic acid cetyl ester, deionized water, emulsifying agent is 300 ~ 400rpm stirring and emulsifying 65-70min at 50 DEG C；It is subsequently adding porogen, cross-linking agent, continues high-speed stirred 30 minutes, ultrasonic 3 ~ 10min de-soak after stirring；
(2) passing into nitrogen 15 minutes in moving to above-mentioned emulsion, seal and magnetic agitation, react 5 hours at 65 DEG C, obtain spongy polymerizate, after reaction terminates, elimination gel, gained emulsion to constant weight, obtains porous high-oil-absorption resin in 80 DEG C of oven dryings。
Further, described emulsifying agent, it is the homogeneous latex emulsion of 12-15% that deionized water forms emulsifying agent mass content, and wherein emulsifier is the 30% of polymerization single polymerization monomer quality, and described emulsifying agent is polyoxyethylene lauryl ether。
Further, described porogen is one or both in silicone oil, ethyl acetate。
Further, described cross-linking agent is one or both in diallyl phthalate, Ethylene glycol dimethacrylate。
Further, described porogen is ethyl acetate, and cross-linking agent is Ethylene glycol dimethacrylate。
Further, described dosage of crosslinking agent is the 0.5-0.9% of overall reaction system quality, and porogen consumption is 35-40%。
The positive effect of the present invention is in that: reaction process is simple, and quickly, finished product oil absorbency is high, to the oil suction multiplying power of toluene and kerosene all more than 9 times。
