Abstract

The invention discloses a hydrophobic resin oil adsorption material and a preparation method, and belongs to the technical field of environment function material preparation. Firstly, a phenol-formaldehyde resin prepolymer is prepared from formaldehyde and phenol under the alkaline condition, with the prepolymer as a continuous phase, a cross-linking agent, an initiator, a certain quantity of a surfactant and a dispersed phase are added to form stable high-internal-phase emulsion, and a porous resin material (PR) is obtained through free radical polymerization; then, hydrophobicity modification is carried out on the obtained resin material, a one-step reaction is carried out with dopamine, ferroferric oxide nanoparticles and mercaptan as raw materials, and a hydrophobic material (SPR) is obtained after a series of treatment is carried out; finally the obtained material is applied to adsorbing oily contaminants.

Description

technical field [0001] The invention belongs to the technical field of preparation of environmental functional materials, and in particular relates to a hydrophobic resin oily adsorption material and a preparation method. Background technique [0002] In recent years, with the continuous development of the petroleum industry and the transportation industry, the environmental pollution caused by oil leakage has also intensified. In order to effectively deal with these emergencies, oil-water separation has become an important part of scientific research. Among them, adsorbent has become an effective means to deal with oil spills, which requires that the adsorbent has an efficient adsorption effect on oily substances and will not absorb water due to the mixing of oil and water. Therefore, how to prepare superhydrophobic and high adsorption capacity Adsorbents have become a research hotspot. [0003] Superhydrophobic materials are generally divided into two types. One is to ach...
