Embodiment 1

[0023] Add dispersant gelatin to water to prepare 0.3-5.0% aqueous solution, stir at 30--50°C to dissolve and cool. Then add 20---30 parts of butyl methacrylate, 70---80 parts of 2-ethylhexyl acrylate and 0.1%-0.6% of the total monomer amount of 1,4-butanediacrylate under stirring. Alcohol ester, benzoyl peroxide with 0.5%-1.6% of the total amount of monomers and carbon tetrachloride as a solvent, are heated up while stirring under the protection of nitrogen, and when the temperature reaches 70-100°C, the polymerization reaction starts. The reaction was maintained at this temperature for 5-7 hours. After the reaction is completed, the product is cooled, filtered, washed several times with hot water at 60-80°C, extracted with methanol as the solvent carbon tetrachloride, and dried in an oven at 50-70°C to obtain a porous super oil-absorbing resin.

[0026] Add dispersant gelatin to water to prepare 0.3-5.0% aqueous solution, stir at 30--50°C to dissolve and cool. Then add 20---30 parts of butyl methacrylate, 70---80 parts of butyl acrylate, 0.1%--0.6% of the total amount of monomers, 1,4-butylene glycol diacrylate, mono 0.5%-1.6% of the total amount of benzoyl peroxide and ethyl acetate as a solvent, and the temperature is raised while stirring under the protection of nitrogen. When the temperature reaches 70-100°C, the polymerization reaction starts. The reaction was maintained at this temperature for 5-7 hours. After the reaction is completed, the product is cooled, filtered, washed several times with hot water at 60-80°C, extracted with methanol as the solvent ethyl acetate, and dried in an oven at 50-70°C to obtain a porous super oil-absorbing resin.

Embodiment 3

[0029] Add dispersant gelatin to water to prepare 0.3-5.0% aqueous solution, stir at 30--50°C to dissolve and cool. Then add 20---30 parts of isobutyl methacrylate, 70---80 parts of 2-ethylhexyl acrylate and 0.1%--0.6% of the total monomer amount of 1,4-butyl diacrylate under stirring. Glycol ester, benzoyl peroxide with 0.5%-1.6% of the total amount of monomers and toluene as a solvent, are heated up while stirring under nitrogen protection, and the polymerization reaction starts when the temperature reaches 70-100°C. The reaction was maintained at this temperature for 5-7 hours. After the reaction is completed, the product is cooled, filtered, washed several times with hot water at 60-80°C, extracted with methanol as the solvent toluene, and dried in an oven at 50-70°C to obtain a porous super oil-absorbing resin.

Abstract

The invention relates to a sewage treatment agent that uses methacrylic acid long chain ester and crylic acid short chain ester as monomer, and water as disperse phase, and adds dispersing agent, initiator agent, crosslink agent and organic solvent. The method is that: adding dispersing agent into water to make 0.3-5.0% aqueous solution and whisking under 30-50 degree centigrade for cooling; adding the mixture of 24-34% methacrylic acid long chain ester, 65-75%crylic acid short chain, 0.1-0.6% crosslink agent, and 0.5-1.6% initiator agent while whisking; under the protection of nitrogen gas, rising the temperature until reaching 70-100degree centigrade, the polymerization beginning and lasting for 7-9 hours; after reaction, cooling and filtrating the production, washing several times by 50-70 degree centigrade hot water, excerpting by methanol, putting into bake oven for baking, then the porosity high oil absorption rosin. It has high blotter scale factor and high blotter efficiency. Moreover, it could be used repeatedly, thus the secondary pollution would be avoided.

Description

technical field [0001] The invention relates to a sewage treatment agent, in particular to a porous high-oil-absorbing resin and a preparation method thereof. The oil-absorbing ratio and oil-absorbing efficiency are high, and the resin can be used repeatedly, avoiding secondary pollution, and the cost is low. Background technique [0002] With the development of my country's chemical industry, the environmental pollution caused by oily sewage, waste liquid and industrial accidents such as the leakage of oil tankers is becoming more and more serious. In organic wastewater, benzene, toluene and cyclohexane are commonly used organic solvents account for a large proportion. At present The common way to recover these oily solvents is to use oil-absorbing materials, but traditional oil-absorbing materials mainly use the capillary action of the surface, gap and cavity of the material to absorb oil, which has the characteristics of not only absorbing oil but also absorbing water, and ...
