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 is as follows:

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

[0029] (2) In the rubber solution, 0.5g of accelerator octylphenol formaldehyde resin and 0.01g of p-benzoquinone dioxime were ultrasonically dispersed, and then 0.2mL of crosslinking agent disulfide dichloride was added with a pipette, Dispense the mixed solution into petri dishes, cover and react 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 fully dried oil-absorbing material is immersed in ...

Embodiment 2

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

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

[0042] (2) In the rubber solution, add 0.3g of accelerator octylphenol formaldehyde resin and 0.005g of p-benzoquinone dioxime, disperse them ultrasonically, and then add 0.2mL of crosslinker disulfide dichloride with a pipette, Dispense the mixed solution into petri dishes, cover and react 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 absorption rate of 0.32g / g a...

Embodiment 3

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

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

[0048] (2) In the rubber solution, add 0.7g of accelerator octylphenol formaldehyde resin and 0.02g of p-benzoquinone dioxime, disperse them ultrasonically, and then add 0.5mL of crosslinking agent disulfide dichloride with a pipette, Dispense the mixed solution into petri dishes, cover and react 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. Leaks and oil wastes caused by oil extraction and oil transportation have caused serious damage to the ecological environment such as oceans, rivers, lakes, and groundwater, which have become increasingly serious problems. [0003] In order to quickly and effectively deal with oil spills and organic solvents in the water, and minimize the pollution of the ocean and fresh water caused by oil spills and oil pollution, at the same time, in order to eliminate environmental pollution caused by domestic oil, it is urgent to develop an efficient oil absorption material. Oil-absorbing materials prepared from natural...
