Problems solved by technology

[0005] At present, most of the oil-absorbing materials in the prior art have problems such as complex formula, high cost, low oil absorption ratio, poor oil retention, poor oil absorption reversibility, and slow oil absorption rate, which are difficult to meet the processing requirements.
For example, the Chinese invention patent whose publication number is CN103588927A discloses a preparation method of a high oil-absorbing acrylic resin, and the oil absorption ratio of the prepared high oil-absorbing acrylic resin to toluene and kerosene is 9 to 10 times, which cannot meet the requirements of the current art. Higher and higher oil absorption ratio requirements for oil-absorbing materials

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a porous material for absorbing grease and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of oil exploration, the environmental pollution caused by oil leakage and the damage to the ecological environment caused by oily wastewater and waste liquid have become increasingly serious, which has seriously affected the sustainable development of the environment in the future. Therefore, it is urgent to develop excellent oil-absorbing materials to deal with the severe oil pollution problem. [0003] Traditional oil-absorbing materials, such as porous materials such as sponge and clay, are widely used. Although these materials have good oil-absorbing effects, due to the structural properties of the materials themselves, traditional oil-absorbing materials have the disadvantages of low oil absorption and low oil-wat...
