Abstract

The invention relates to a preparation method of cellulose-based oil-absorption material, which includes the steps of: after activating process for plant cellulose, adding polyvinyl alcohol aqueous solution, stirring and heating under nitrogen protection, adding evocating agent, reaction monomer and cross linker, heating under stirring, remaining constant temperature, precipitating and filtering product, washing with hot water, drying and obtaining cellulose-based oil-absorption material. The method has the advantages of: simple operation, moderate reaction condition, plant cellulose basic raw material, low synthetic production cost, oil-absorption ability, especially high oil-absorption ability for heavy oil; the obtained product not only has biodegradability of cellulose, but also has high oil-absorption ability of lipophilic monomer, thereby solving the difficult problem that common oil-absorption materials cannot have high oil-absorption ability and biodegradability at the same time.

Description

technical field [0001] The invention relates to a preparation method of a cellulose-based oil-absorbing material technical background [0002] Various oils as industrial blood will affect the workplace and pollute the ecological environment due to dripping, leaking, splashing, etc. during transportation, replacement, and use; in oil extraction, oil refining, petrochemical, and food industries A large amount of oily waste water will be produced in the production process of the production process and the lubricating oil cooling process of the mechanical industry, which will pollute the water environment, endanger aquatic organisms, and even enter the human body through the food chain, endangering human health; there will also be a large amount of oil fume in the catering industry and daily life Air pollutes the atmosphere; washing kitchen utensils in daily life, a large amount of waste water containing edible oil flows into the sewer without any treatment, and after a long tim...
