Problems solved by technology

[0002] Various oils, as industrial blood, will affect the workplace and pollute the surrounding ecological environment due to dripping, leaking, and splashing during transportation, replacement, and use; in oil extraction, oil refining, and petrochemical, The production process of the food industry and the lubricating oil cooling process of the machinery industry will also produce a large amount of oily wastewater, pollute the water environment, endanger aquatic organisms, and even enter the human body through the food chain, endangering human health; in the catering industry and daily life There will also be A large amount of oil fume 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. After a long time, it will corrode and block the sewer pipe, which will bring a lot of inconvenience to people's life. Therefore, the development of excellent performance Oil-absorbing materials have become the focus and hotspot of current research

Abstract

The invention provides an oil absorption material containing a silicon polymer and preparation methods thereof and relates to a macromolecule oil absorption material. The oil absorption material containing the silicon polymer is formed by copolymerizing an acrylic monomer A and an organic monomer B. One preparation method comprises the steps of adding the monomer A, the monomer B, clean water, an initiator, a cross-linking agent, a dispersing agent and a pore-foaming agent in a reactor, removing air in the reactor, leading inert gas into the reactor and performing sealing; mixing and heating materials to perform polymerization reaction; terminating the reaction and depositing, cleaning and drying a product to obtain the oil absorption material containing the silicon polymer. The other preparation method comprises the steps of adding the monomer A, the monomer B, a solvent, a photoinitiator, a cross-linking agent and a pore-foaming agent in the reactor, sealing and stirring the materials to be mixed evenly; placing the reactor into an ultraviolet light irradiation device to be irradiated and perform reaction; and terminating the reaction and depositing, cleaning and drying a product to obtain the oil absorption material containing the silicon polymer.
