Problems solved by technology

[0002] In recent years, news of oil spills at sea and road pipelines has occurred frequently. Oil pollution from food production, catering, oil exploration and chemical industry is also very serious and difficult. The oil spilled or spilled is exposed and retained. In the ocean, soil and atmosphere, because it is difficult to be naturally degraded, it will cause serious pollution to the environment
[0003] At present, the ways to solve this problem include mechanical extraction, in-situ combustion, chemical degradation, etc., but the efficiency of mechanical extraction is low, the application area of ​​in-situ combustion is too narrow, and chemical degradation will cause energy waste. Therefore, the method of using oil-absorbing materials has begun widely used
There are three types of common oil-absorbing materials, but they all have some defects: although inorganic mineral materials are cheap and safe, they have low oil absorption, poor oil-water separation, and are not combustible; organic synthetic materials have large oil absorption and good buoyancy, but Its biodegradability is poor, and it cannot be recycled; while natural oil-absorbing materials are economical, practical, non-toxic and harmless, but have poor buoyancy and poor oil-water separation
[0004] In view of this, there is an urgent need in this field for an oil-absorbing agent with strong oil-absorbing capacity, good oil-water separation, convenient use, convenient recycling, and even demulsification performance to solve the "problem" of poor adsorption effect and poor comprehensive performance of current oil-absorbing materials.
