Embodiment 1

[0008] Embodiment 1: 0.18 gram of polyvinyl alcohol, 10 milliliters of cyclohexane, 0.8 gram of sodium dodecylbenzenesulfonate, 5 milliliters of butyl methacrylate, 0.4 gram of stearyl acrylate, and 0.02 gram of potassium persulfate were added to 15 In milliliter deionized water, pass nitrogen gas to deoxygenate for 30 minutes, heat up to 80 degrees Celsius, adjust the stirring rate to 600 rpm, carry out suspension emulsion polymerization, and add 2 milliliters of diallyl phthalate to continue the reaction for 15 minutes. Hours, the product was cooled, separated, extracted by a Soxhlet extractor for 12 hours, and vacuum-dried to obtain a super oil-absorbing resin.

[0009] The oil absorption ratio of the obtained high oil-absorbing resin to toluene was 24 times.

Embodiment 2

[0010] Embodiment 2: with 0.02 gram of polyvinyl alcohol, 10 milliliters of cyclohexane, 1.6 gram of sodium dodecylbenzene sulfonate, 5 milliliters of butyl methacrylate, 0.8 gram of stearyl acrylate, 0.02 gram of potassium persulfate, 12 Add 2.5 ml of diallyl phthalate into 2.5 ml of deionized water, pass nitrogen gas to remove oxygen for 20 minutes, raise the temperature to 75 degrees Celsius, adjust the stirring rate to 700 rpm, and carry out suspension emulsion polymerization, react for 2 hours, and the product is cooled, Separation, Soxhlet extraction for 12 hours, and vacuum drying to obtain a high oil-absorbing resin.

[0011] The oil absorption ratio of the obtained high oil-absorbing resin to toluene was 18 times.

Embodiment 3

[0012] Embodiment 3: 0.02 gram of polyvinyl alcohol, 5 milliliters of cyclohexane, 1.4 gram of sodium dodecylbenzene sulfonate, 5 milliliters of butyl methacrylate, 0.1 gram of octadecyl acrylate, and 0.005 gram of potassium persulfate were added to 5 In milliliter deionized water, pass nitrogen gas to remove oxygen for 10 minutes, heat up to 80 degrees Celsius, adjust the stirring rate to 800 rpm, carry out suspension emulsion polymerization, and add 10 milliliters of diallyl phthalate for 30 minutes to react, and continue the reaction for 2 Hours, the product was cooled, separated, extracted by a Soxhlet extractor for 18 hours, and vacuum-dried to obtain a high oil-absorbing resin.

Abstract

The invention discloses a method for preparing high-oil absorption resin, which is characterized by adding a dispersant of polyvinyl alcohol, a precipitating reagent of cyclohexane, an emulsifying agent of sodium dodecylbenzene sulphonate, a single body of butyl methacrylate and stearyl methylacrylate, an initiator of potassium persulphate into deionized water, introducing nitrogen for deoxygenation, performing suspended emulsion polymerization, after reaction for a certain time, adding a cross-linking agent of diallyl phthalate, continuously reacting for at least two hours, performing cooling, separation, extraction by using an Soxhlet extractor for at least 12 hours and vacuum drying to obtain the products. By the aid of the preparation method of the invention, porous high-oil absorption resin can be obtained, which has oil-absorption capability to toluene reaching up to 24, and can be applied to the field of environmental protection and the like.

Description

technical field [0001] The invention relates to a method for preparing a high oil-absorbing resin, in particular to a method for preparing a loose and porous high oil-absorbing resin. Background technique [0002] As a high-efficiency oil-absorbing material, high oil-absorbing resin overcomes the shortcomings of traditional oil-absorbing materials. Not easy to aging and other excellent performance. High oil-absorbing resin has a small density and floats on the water surface. It can be used for the treatment of oil slicks on the water surface, and is easy to recycle. It has broad development prospects in environmental protection. [0003] The traditional methods for preparing super oil-absorbing resins are suspension polymerization, emulsion polymerization and dispersion polymerization. The suspension polymerization method has the advantages of low system viscosity, easy temperature control, simple post-treatment process, and low production cost. It is widely used in indust...
