Abstract

The invention provides a safe, pollution-free and efficient organic absorbent and a preparation method thereof. The absorbent comprises the following components in parts by weight: 45-80 parts of natural fibers, 10-30 parts of a silane coupling agent, 1-5 parts of a bio-enzyme catalyst, 0.5-10 parts of a flame retardant and 7-20 parts of a dissolving medium. The absorbent adopts natural fiber as a main component, is biodegradable, is low in post-treatment cost, and meets the requirement of environmental protection; the surface of the natural fiber is modified through the silane coupling agent, so that the water absorption of the natural fiber is greatly reduced, and the pollutant absorption capacity is improved; pollutants can be degraded into low-molecular-weight organic matter or inorganic matter such as water and carbon dioxide from high-molecular-weight organic matter through the biological catalytic enzyme, so that the pollutants are changed into solid wastes from hazardous wastes; and the absorbent can absorb oil gas and lock the oil gas, so that secondary disasters caused by flammability are effectively prevented. The absorbent is suitable for various occasions such as water bodies, soil, working conditions and factories, absorbable substances are not limited to oil pollutants, and the adsorbent is also suitable for cosmetics, lubricants, pigments and the like.

Description

technical field [0001] The invention relates to the field of absorbent materials, in particular to a safe and pollution-free high-efficiency organic absorbent and a preparation method thereof. Background technique [0002] In recent years, the economy has developed rapidly, and the oil industry and offshore oil transportation industry have flourished, but it has also brought serious oil pollution, and large-scale oil spills and oil spill accidents at sea have occurred frequently; Cause crude oil leakage, improper treatment will also lead to soil pollution, which has caused a great threat to the environment, animals, plants and human beings. [0003] At present, when dealing with oil spills and oil spill accidents, the oil-absorbing materials usually used include inorganic mineral materials, artificially synthesized polymer oil-absorbing materials, and natural organic oil-absorbing materials. The advantages of inorganic mineral materials are low price and safety, but they ha...
