Abstract

The invention relates to a preparation method of an oil absorbing material, and the oil absorbing material is prepared by subjecting a basic material namely palm fibers to hydrophobic modification. The preparation method comprises the following steps: washing palm fibers, drying palm fibers, cutting the palm fibers into sections with a length of 0.5 to 5 cm; putting the palm fibers into a hydrophobic agent solution, soaking for 10 to 120 minutes at a temperature of 25 to 100 DEG C, taking out the palm fiber containing a hydrophobic agent, and quickly drying so as to obtain the modified oil absorbing material; wherein the hydrophobic agent is composed of paraffin, palm wax, or a mixture of paraffin and palm wax, the addition amount of the hydrophobic agent is 0.01 to 0.2 times of the weight of the palm fibers, the solvent is one or more of carbon tetrachloride, vinyl acetate, ethanol, and benzene, and the addition amount of the solvent is 20 to 800 times of the weight of the hydrophobic agent. Cheap and easily-available natural plant palm is taken as the raw material, the oil absorbing material is prepared by carrying out hydrophobic modification on the palm fibers, and compared with the oil absorbing materials prepared through chemical synthesis, the provided oil absorbing material has the advantages of low cost, biodegradability, and excellent oil absorbing performance.

Description

Technical field [0001] The invention belongs to the field of water body oil spill pollution treatment and new material application fields in environmental protection. A method for preparing oil-absorbing materials by impregnating and modifying palm fibers with a hydrophobic agent is disclosed. Background technique [0002] In recent years, with the vigorous development of world industry, oil and its products entering the ocean, rivers and lakes and other water environments due to various accidents during the mining, refining, storage, transportation and use processes will cause serious water pollution and damage the ecological environment. The threat to people’s lives cannot be ignored. These oil spills form an oil film covering the water surface, which not only wastes precious petroleum resources, but also blocks the process of water-gas exchange, affects the biological chain cycle, disrupts the ecological balance of water bodies, and causes serious harm to water organisms.
