Abstract

The invention relates to a quick high-efficiency oil-adsorbing resin and a preparation method thereof. According to the preparation method, a monomer, a crosslinking agent, an initiator, a dispersing agent and other raw materials are proportionally subjected to suspension polymerization to prepare the quick high-efficiency oil-adsorbing resin. The quick high-efficiency oil-adsorbing resin has higher adsorptivity and higher oil retention property, and can be repeatedly regenerated and reused. More importantly, the oil adsorptivity of the prepared oil-adsorbing resin for carbon tetrachloride within 10 minutes is 19.52 g / g, the oil adsorptivity for gasoline is 12.62 g / g, the oil adsorptivity for paraxylene is 11.19 g / g, the oil adsorptivity for machine oil is 9.39 g / g, and the oil adsorptivity for diesel is 9.2 g / g. The quick high-efficiency oil-adsorbing resin is suitable for treating oil slick in the fishing boat centralized mooring area, and can also be used for quick treatment of oil leakage accidents.

Description

technical field [0001] The invention relates to a fast and high-efficiency oil-absorbing resin and a preparation method thereof, belonging to the technical field of functional polymer synthetic materials. Background technique [0002] Fishing boats in the fishing boat mooring area will leak oil during refueling and maintenance. If the leaked oil is not treated in time, it will cover the water surface. On the one hand, it will affect the surrounding water quality and cause the water quality to decline. On the other hand, it will cover the The oil on the water surface will affect the dissolved oxygen content in the water body, and pose a hazard to the growth of aquatic organisms in the water body. [0003] Traditional oil-absorbing materials such as sponges, polypropylene non-woven fabrics, oil-absorbing cotton, and kapok fibers also absorb water while absorbing oil. The oil absorption rate is not high, and the oil retention performance is poor, and oil-water separation cannot...
