Problems solved by technology

[0004] The existing acrylic oil-absorbing resins all have considerable oil-absorbing ratios, but there is generally a problem of slow oil-absorbing rates. Once a crude oil spill occurs, oil pollution will spread rapidly. The above-mentioned oil-absorbing resins often need several hours to reach the maximum oil-absorbing ratio, and cannot Effectively adsorb oil products in the first time, the timeliness is greatly restricted, and needs to be improved urgently

preparation example Construction

[0043] A preparation method of oil-absorbing resin, specifically according to the following steps:

[0044] Step 1, preparation of aqueous phase,

[0045] According to the volume ratio, mix 30-45% of water and 10-25% of dispersant evenly, and heat up to 80°C to obtain the water phase;

[0046] Wherein, water is distilled water or deionized water, and dispersant is polyvinyl alcohol solution;

[0047] Step 2, the preparation of the oil phase,

[0048] Mix 3-8 parts of polymer monomer, 0.045-0.095 parts of initiator, 0.03-0.2 parts of crosslinking agent, and 0.5-2 parts of porogen according to the ratio of parts by mass to obtain an oil phase;

[0049] Among them, the polymer monomer is composed of butyl methacrylate, styrene and maleic acid ester according to the mass ratio of 2.0-3.0:4.0-6.0:2.0-3.0; maleic acid ester is selected from maleic acid A mixture of any one or more of dibutyl diacid, dioctyl maleate or dilauryl maleate in any proportion;

[0050] The initiator is...

Embodiment 1

[0059] According to the volume ratio, mix 30% distilled water and 25% polyvinyl alcohol solution evenly, heat up to 80°C to obtain the water phase; , 0.2 parts of cross-linking agent, 2 parts of ethyl acetate are mixed uniformly to obtain an oil phase; wherein, the polymer monomer is composed of butyl methacrylate, styrene and maleic acid ester according to the ratio of 2.0:4.0:3.0 Mass ratio composition; maleic acid ester is selected from dibutyl maleate; crosslinking agent is selected from divinylbenzene; the oil phase is added to the water phase and the temperature is raised to 78°C under a nitrogen atmosphere at 240rpm Stir and mix at a certain stirring speed, so that the oil phase forms uniform droplets in water, and keep at 78°C for 6 hours until the liquid titration is finalized; raise the temperature to 88°C, keep it warm for 2 hours, cool down, filter the reaction solution, wash and remove Ethyl acetate and impurities, that is.

Embodiment 2

[0061] According to the volume ratio, mix 45% deionized water and 10% polyvinyl alcohol solution evenly, heat up to 80°C to obtain the water phase; Formyl, 0.03 parts of cross-linking agent, 0.5 parts of ethyl acetate are mixed evenly to obtain an oil phase; the polymer monomer is composed of butyl methacrylate, styrene and maleic acid ester according to the ratio of 3.0:6.0:2.0 Mass ratio composition; maleic acid ester is selected from dioctyl maleate; crosslinking agent is selected from -1,4-butanediol methacrylate; the oil phase is added to the water phase in a nitrogen environment Raise the temperature to 82°C under low temperature, stir and mix at a stirring speed of 210rpm, so that the oil phase forms uniform droplets in the water, keep at 82°C for 1 hour until the droplet is shaped; raise the temperature to 90°C, keep it warm for 0.5 hours, and cool down , The reaction solution was filtered, washed to remove ethyl acetate and impurities, that is.

Abstract

The invention relates to an oil absorbing resin, which comprises, by mass part, 40-60 of a water phase and 5.25-7.5 of an oil phase. The water phase is composed of, by volume, 30-45 of water and 10-25 of a dispersing agent. The oil phase is composed of, by mass, 3-8 parts of a polymer monomer, 0.045-0.095 part of an initiator, 0.03-0.2 part of a cross-linking agent, and 0.5-2 parts of a pore-foaming agent. The invention also discloses a preparation method of the oil absorbing resin, and the method includes: adding the oil phase into the water phase, performing heating to 78-82DEG C and conducting mixing, maintaining the temperature at 78-82DEG C for 1-6h till liquid drops shape; raising the temperature to 88-90DEG C, carrying out heat preservation for 0.5-2h and performing cooling, thus obtaining the resin. The invention discloses application of the oil absorbing resin in edible oil, gasoline, kerosene or diesel oil adsorption. And the oil absorbing resin has the advantages of high elasticity, high swelling speed, high strength, and fast oil absorption rate.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploitation, and relates to an oil-absorbing resin, a preparation method thereof and an application in the adsorption of edible oil, gasoline, kerosene and other oil products. Background technique [0002] With the increase in the amount of petroleum and petroleum products, the leakage and various oily wastes generated during petroleum exploration and processing, refining, storage, transportation and use of petroleum products have caused great harm to the marine ecological environment and freshwater ecological environment. destroy. Oil spills and oil stains in water not only reduce the quality of marine and freshwater environments, affect the cycle of food chains, destroy ecological balance, but also threaten human health. The damage caused by marine oil spills has the characteristics of high degree of harm, wide spread, and difficulty in cleaning up. To solve these problems, it is urgent to d...
