Abstract

The invention discloses a preparation method and an application of a super-hydrophilic basalt fiber material. The novel oil-water separation super-hydrophilic basalt fiber material having an underwater oleophobic function is prepared by firstly preparing a gulcomannan solution, regulating the pH value of the solution to remove acetyl of gulcomannan to obtain more hydroxyls, then taking a basalt fiber cloth as a base material, and coating the deacetylation gulcomannan solution on the surface of the fiber cloth. The basalt fiber material obtained through the method has the advantages of low cost, green, environment protection, high separation efficiency, oil rub resistance, acid and alkali resistance and the like, is a novel efficient oil-water separation material, and has a higher practicalvalue and a bright market prospect in the fields of oil spilling, treatment of chemical products, domestic oily sewage and the like.

Description

technical field [0001] The invention relates to the field of oil-water separation and the field of water surface oil pollutant treatment, in particular to a preparation method and application of a super-hydrophilic basalt fiber material used for water surface oil spill treatment and domestic oily sewage treatment. Background technique [0002] With the development of modern industry, people's demand for petroleum products is increasing year by year. Along with frequent oil exploitation and transportation of petrochemical products, oil spills on the water surface and oil spill accidents occur frequently, causing great harm to the water environment. In addition, the random discharge of living and dining sewage leads to water pollution. Therefore, oil-water separation is a significant topic. [0003] Super-hydrophilic materials can quickly absorb water, and the contact angle of water droplets on its surface is zero. Water droplets spread on the super-hydrophilic materials to ...
