Abstract

The invention discloses a method for obtaining an oil absorption material by adopting melamine resin foam as a matrix, and belongs to the technical field of oil pollution treatment. The method comprises the following steps that the melamine resin foam is placed in a hydrophobing agent solution, and vacuum impregnation is carried out for 20-60 minutes at the temperature of 25 DEG C to 100 DEGC; the melamine resin foam containing a hydrophobing agent is taken out and dried fast, a hydrophobing agent infusion with the melamine resin foam as the matrix is obtained, and the oil absorption material is obtained. According to the oil absorption material prepared by adopting the melamine resin foam as the matrix, the modifying method that the hydrophobing agent is loaded in a dipping mode is adopted, the method is a simple physical modifying method, the process is simple, cost is low, and the advantages of being porous, large in specific surface area, low in density, high in oil absorption performance and good in oil retention effect are achieved.

Description

technical field [0001] The invention relates to the technical field of oil pollution treatment, in particular to a method for obtaining an oil-absorbing material using melamine resin foam as a matrix. Background technique [0002] In recent years, with the vigorous development of the world's industry, petroleum and its products have entered the ocean, rivers and lakes and other water bodies due to various accidents during the process of mining, refining, storage, transportation and use, which will cause serious water pollution and affect the ecological environment. The threat to people's lives cannot be ignored. These oil spills form an oil film covering the water surface, which not only wastes precious oil resources, but also blocks the process of water-air exchange, affects the biological chain cycle, destroys the ecological balance of the water body, and causes serious harm to aquatic organisms. If it is not dealt with in time, it will bring great harm to our ecological ...
