Embodiment 1

[0015] Embodiment 1 A kind of preparation method of porous super oil-absorbing resin

[0016] (1) Stir and emulsify 40g of cetyl methacrylate, 100g of deionized water, and 12g of polyoxyethylene lauryl ether at 300~400rpm at 50°C for 65-70min; then add 0.7g of ethyl alcohol, 80g of ortho Diallyl phthalate, continue to stir at high speed for 30 minutes, after stirring evenly, ultrasonic 3~10min to defoam;

[0017] (2) Nitrogen gas was passed into the above emulsion for 15 minutes, sealed and magnetically stirred, and reacted at 65°C for 5 hours to obtain a spongy polymer product. After the reaction was completed, the gel was filtered off, and the obtained emulsion was dried in an oven at 80°C until constant Heavy, to get a high oil-absorbing acrylic resin. The oil absorption ratio of toluene and kerosene is 9 times.

Abstract

The invention discloses a preparation method of a porous super oil-absorbing resin. Cetyl methacrylate, deionized water, and an emulsifier are stirred and emulsified at 300-400 rpm for 65-70 minutes at 50°C; Mixing agent, continue to stir at high speed for 30 minutes, after stirring evenly, ultrasonic 3~10min to defoam; then pass nitrogen gas into the above emulsion for 15 minutes, seal and magnetically stir, react at 65°C for 5 hours to obtain a spongy polymer product, react After the end, the gel was filtered off, and the obtained emulsion was dried in an oven at 80° C. to a constant weight to obtain a high oil-absorbing acrylic resin. The reaction process is simple and fast, and the oil absorption rate of the finished product is high, and the oil absorption rate of toluene and kerosene is more than 9 times.

Description

technical field [0001] The invention relates to a preparation method of a porous high oil-absorbing resin. Background technique [0002] High oil-absorbing resin adsorption materials have been extensively researched, developed and applied in recent years because of their ability to adsorb a variety of oil products, their large oil absorption ratio and fast oil absorption rate, and their prospects are very broad. [0003] Super oil-absorbing resin is a low-crosslinked polymer composed of lipophilic monomers. The molecules have a three-dimensional cross-linked network structure, and there are certain micropores inside. Through the solvation of the intramolecular lipophilic segment and the oil molecule, the polymer segment is stretched. When the polymer is fully swollen, the polymer chain stretches To a certain extent, it slowly retracts, and there is an elastic retraction force, and finally reaches a thermodynamic equilibrium, causing the resin to expand and absorb oil.
