Embodiment 1

[0023] Weigh 600g of deionized water and 1g of polyvinyl alcohol dispersant into a three-necked flask, heat to 45°C until the polyvinyl alcohol is completely dissolved, and sequentially add 100g of butyl methacrylate to the three-necked flask under the protection of high-purity nitrogen. 0.5g diethylene glycol diacrylate crosslinking agent, 0.6g benzoyl peroxide initiator, slowly heated to 80℃, reacted for 4 hours to obtain polymer oil-absorbing microspheres; then 1g styrene and 2g of divinylbenzene, reacted for 2 hours to form a layer of high cross-linking surface structure on the outside of the polymer oil-absorbing microspheres; then the reaction system was cooled to room temperature under stirring conditions, and finally the oil-absorbing microspheres were filtered. After washing with water, filtering with suction, and drying, shell-like polymer oil-absorbing microspheres can be obtained.

Abstract

The present invention relates to a shell-like polymer oil-absorbing microsphere preparation method, which adopts a suspension polymerization method, and specifically comprises: adding deionized water and a dispersing agent into a three-necked flask with a stirring device, heating to a temperature of 30-50 DEG C until the dispersing agent is dissolved, sequentially adding an acrylate or methacrylate reaction monomer, a diacrylate cross-linking agent of a diol and a free radical polymerization initiator to the three-necked flask under the protection of high purity nitrogen, slowly heating to a temperature of 60-80 DEG C, carrying out a reaction for 3-6 h to obtain polymer oil-absorbing microspheres, adding styrene and divinylbenzene, carrying out a reaction for 1-3 h so as to generate the high cross-linking degree surface layer structure on the outer surface of the microsphere, cooling the reaction system to a room temperature under the stirring condition, and carrying out filtration, water washing, suction filtration and drying on the oil-absorbing microsphere to obtain the shell-like polymer oil-absorbing microsphere, wherein a mass ratio of the deionized water to the dispersing agent is 100:0.03-4.5. The shell-like polymer oil-absorbing microsphere of the present invention has the characteristic of rapid oil absorbing.

Description

Technical field [0001] The invention is a method for preparing shell-shaped polymer oil-absorbing microspheres, and relates to the technical field of the petroleum industry. Background technique [0002] With the increasing frequency of offshore oil exploration activities and offshore oil transportation, offshore oil spills have emerged one after another. Once oil enters the ocean, it will cause incalculable harm to the natural environment, aquaculture, shallow water coasts, and dock industries. Oil spills are called the super killer of the marine environment. Pollution of water bodies on the road will also cause serious damage to the environment. For example, in 2005, the Songhua River was affected by the explosion of a chemical plant, and benzene entered the river. As the water flowed, pollutants drifted downstream, causing serious damage to the Heilongjiang section of the Songhua River. Pollution has threatened the ecology, aquatic products and drinking water of residents on ...
