Abstract
The invention belongs to the technical field of preparation of functional polymer materials, and particularly relates to a preparation method of oil-absorbing resin. Cedar leaf activated carbon is prepared by taking cedar leaves as a raw material, soybean lecithin and the cedar leaf activated carbon are blended and fermented to obtain modified cedar leaf activated carbon, and the oil absorption capacity of the oil-absorbing resin prepared by the method of the invention is greatly enhanced by taking the modified cedar leaf activated carbon as a raw material. Acrylic resin is prepared by takingdodecyl acrylate, dodecyl methacrylate, hexadecyl acrylate and the like as raw materials, the acrylic resin has a three-dimensional cross-linked network structure, and therefore, the purposes of oil absorption and oil retention are achieved. Egg white protein contains a large number of disulfide bonds and has good foaming capacity, after egg white protein is mixed with the acrylic resin, adsorption and wrapping of oil stain molecules by the acrylic resin are improved, and active groups on the surface of the modified acrylic resin and active groups on the surface of activated carbon are combined together due to hydrogen bond adsorption force and Van der Waals force, so that the resin has a wide application prospect.
Description
technical field [0001] The invention belongs to the technical field of preparation of functional polymer materials, and in particular relates to a preparation method of oil-absorbing resin. Background technique [0002] In recent years, with the development of society and economy, people's production activities have continuously polluted water resources, seriously threatening the natural environment on which people live. Among them, oil pollution seriously threatens the marine environment and the living environment of urban residents. Especially with the increasing frequency of offshore oil exploitation and transportation, oil spill accidents at sea occur from time to time. When oil enters the ocean, it will cause incalculable harm to the natural environment, aquaculture, shallow water coasts, and dock industries. According to statistics, nearly 10 million tons of oil enter the water body through various channels every day in the world, polluting the environment. Therefor...
