The invention relates to the technical field of oil-water separation materials, in particular to an oil-water separation material based on polyester bottle flake regenerated fibers and a preparation method thereof.
Background
The oil-water separation technology is a technology for realizing the processes of separating, purifying, concentrating and the like of organic and inorganic components of a material by utilizing the selective separation of the material, has the advantages of high efficiency, energy conservation, environmental protection, simple separation process, recycling and the like, and is widely applied to the fields of food, medicine, environmental protection, chemical industry, metallurgy, energy, petroleum, water treatment and the like. The oil-water separation material is the key of the oil-water separation technology, and the performance of the oil-water separation material directly determines the oil-water separation effect. Therefore, the development of the oil-water separation material with good comprehensive performance and performance stability is particularly important.
The traditional oil-water separation material (such as active carbon, graphite, clay, diatomite and the like) has the defects of unobvious interfacial infiltration characteristic, weak oil absorption and water repellency, low separation efficiency, difficult material recycling and influence on the using effect of the material, and absorbs a large amount of water at the same time of oil absorption. Other oil-water separation materials on the market have the defects of poor oil-water separation effect, complex preparation process, complicated steps, certain environmental pollution in the aspects of recycling and disposal, and further improvement of mechanical properties, recycling times and oil-water separation efficiency.
The polyester bottle flakes have the advantages of high strength, good brightness, light weight, good transparency, convenient processing, stable size and the like, the global market demand and the application amount are greatly increased, and the waste polyester bottle flakes are increased year by year along with the large-scale use of the polyester bottle flakes. These polyester bottle flakes are non-biodegradable, their waste is prone to "white pollution", and how to better process and reasonably reuse the waste recycled polyester bottle flakes has become a key issue for sustainable development of the polyester industry.
The regenerated fiber of the polyester bottle chip is a fiber material prepared by taking the recovered polyester bottle chip as a raw material, and the material is one of the most promising oil-water separation materials because the material is cheap and easy to obtain and has the property of hydrophobic and oleophilic, and after the material is processed into a three-dimensional porous material, the oil-water separation can be more effectively carried out. However, the existing oil-water separation material based on the regenerated fiber of the polyester bottle flake is rare, requires a complex preparation method and equipment, has high cost and is not beneficial to large-scale production and application.
In order to solve the above problems, chinese patent document CN100344341C discloses a super-hydrophobic/super-oleophilic oil-water separation net, mainly a fabric net formed by metal fibers such as stainless net, copper, iron, titanium, aluminum, or a fabric net formed by fibers such as polyester, nylon, vinylon, etc. is immersed in perfluoro-silicone to prepare a super-hydrophobic/super-oleophilic oil-water separation net covered with a thin layer of poly-perfluoroalkyl silicone film on the surface, the metal net has a complex preparation method, needs multiple soaking times, has a higher curing temperature, and basically belongs to physical adhesion between the poly-perfluoroalkyl silicone and the fabric net, and the poly-perfluoroalkyl silicone film is easy to fall off from the grid during use, so that the poly-perfluoroalkyl silicone film is difficult to reuse. A large amount of toxic organic solvents are used in the preparation process, so that serious pollution is caused. When a large amount of oily wastewater is treated, due to the limited action effect of the single-layer oil-water separation net, multiple layers of separation nets are often required to be used for common operation, and the large-area popularization and use cost is high.
Therefore, the field still needs an oil-water separation material based on the polyester bottle flake regenerated fiber, which has high oil-water separation efficiency, good effect, good cycle performance and relatively low preparation cost, and a preparation method thereof.
