Problems solved by technology

Synthetic organic oil-absorbing materials are mostly in the form of blocks, which are not easy to recycle, which limits their application
[0005] At present, the most commonly used commercial oil-absorbing material is made of polypropylene, which is suitable for dealing with large-area crude oil spills, but there are also disadvantages such as long processing time and low recycling rate.

Embodiment 1

[0027] A butyl rubber composite gel oil-absorbing material, the preparation method of which is as follows:

[0028] (1) Crush butyl rubber, weigh 5g, dissolve it in 100mL chloroform and let it stand for a period of time. When the rubber becomes transparent, that is, the butyl rubber has been fully dissolved to obtain a rubber solution;

[0029] (2) In the rubber solution, 0.5g of accelerator octylphenol formaldehyde resin and 0.01g of p-benzoquinone dioxime were dispersed ultrasonically, and then 0.2mL of crosslinking agent disulfide dichloride was added with a pipette. The mixture was divided into petri dishes, covered and reacted at ambient temperature for 12 hours;

[0030] (3) After the reaction is completed, the obtained composite gel material is alternately washed with toluene and methanol, at least twice each; then dried in a fume hood at room temperature to obtain the butyl rubber composite gel oil-absorbing material.

[0031] The above-mentioned fully dried oil-absor...

Embodiment 2

[0040] A butyl rubber composite gel oil-absorbing material, the preparation method of which is as follows:

[0041] (1) Crush butyl rubber, weigh 5g, dissolve it in 50mL chloroform and let it stand for a period of time. When the rubber becomes transparent, that is, the butyl rubber has been fully dissolved to obtain a rubber solution;

[0042] (2) Add 0.3g of accelerator octylphenol formaldehyde resin and 0.005g of p-benzoquinone dioxime to the rubber solution, ultrasonically disperse them, and then add 0.2mL of crosslinking agent disulfide dichloride with a pipette, The mixture was divided into petri dishes, covered and reacted for 10 hours;

[0043] (3) After the reaction is completed, the obtained composite gel material is alternately washed with toluene and methanol, at least twice each; then dried in a fume hood at room temperature to obtain the butyl rubber composite gel oil-absorbing material.

[0044] The oil-absorbing material obtained in this example has a water abs...

Embodiment 3

[0046] A butyl rubber composite gel oil-absorbing material, its preparation method is as follows:

[0047] (1) Crush butyl rubber, weigh 5g, dissolve it in 150mL chloroform and let it stand for a period of time. When the rubber becomes transparent, that is, the butyl rubber has been fully dissolved to obtain a rubber solution;

[0048] (2) Add 0.7g accelerator octylphenol formaldehyde resin and 0.02g p-benzoquinone dioxime to the rubber solution, ultrasonically disperse them, then add 0.5mL crosslinking agent disulfide dichloride with a pipette, The mixed solution is divided into petri dishes, covered and reacted at ambient temperature for 15 hours;

[0049] (3) After the reaction is completed, the obtained composite gel material is alternately washed with toluene and methanol, at least twice each; then dried in a fume hood at room temperature to obtain the butyl rubber composite gel oil-absorbing material.

Abstract

The invention relates to a butyl rubber composite gel oil absorption material and a preparation method thereof. A three-dimensional network spatial structure is formed by using butyl rubber as a base material, disulfur dichloride as a cross-linking agent and octyl phenol formaldehyde resin and parabenzoquinone dioxime as accelerants. The obtained oil absorption material is small in density, large in oil absorption, fast in rate of adsorption and capable of adsorbing multiple oil products; the oil absorption material can be repeatedly recycled through simple extrusion treatment, so that the cost is effectively reduced. The oil absorption material is a novel environmental-friendly material and widely applied and can be used for recovery of spilled oil in seaborne or land water bodies, treatment of oily wastewater and the like.

Description

technical field [0001] The invention relates to an oil-absorbing material and a preparation method thereof, in particular to a butyl rubber composite gel oil-absorbing material and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the global economy, the demand for oil in various countries has shown an increasing trend. Leakage and oil waste produced in the process of oil exploration and oil transportation have caused serious damage to the ecological environment such as oceans, rivers, lakes, and groundwater, which has become an increasingly serious problem. [0003] In order to quickly and effectively treat oil spills and organic solvents in water, and minimize the pollution of oil spills and oil pollution to oceans and fresh water, at the same time, in order to eliminate environmental pollution caused by domestic oil, it is urgent to develop an efficient oil-absorbing Material. Oil-absorbing materials prepared from...
