Abstract

The invention discloses a high-power oil absorption gel material. According to the high-power oil absorption gel material, polyether polyol, a composite catalyst, a foam stabilizer, organic low-molecule gel, deionized water and a foamer serve as raw materials, and the high-power oil absorption gel material is firstly obtained through one-step-method polymerization reaction. The high-power oil absorption gel material has the crude oil absorption power of 60-100g / g and the oil retention rate higher than 90%. The high-power oil absorption gel material has the advantages of high oil absorption power, good oil retention property, no toxicity, no pollution, low cost, foaming-in-place and the like, can be applied to the adsorption of water surface spillover oil and is particularly applicable to the emergency treatment of water surface spillover oil of rivers and lakes.

Description

technical field [0001] The invention belongs to the field of oil-absorbing materials, and in particular relates to a high-power oil-absorbing gel material and a preparation method of the material. Background technique [0002] In recent years, with the increasing frequency of human activities, a series of accidents such as oil field spills, oil spills from oil tankers, oil pipeline ruptures, and the discharge of oily wastewater have caused serious pollution to rivers and oceans, bringing immeasurable ecological disasters and economic Losses, such as the US Gulf of Mexico and my country's Bohai Bay oil spills. Failure to address these issues will inevitably cause greater damage. The most common way to solve oil spills at home and abroad is to use oil-absorbing materials for adsorption. However, traditional oil-absorbing materials mainly rely on physical adsorption to adsorb oil on the surface of the material or in the internal capillary, and the oil-absorbing effect is not i...
