Abstract

The invention discloses a sponge loaded type organic solvent absorbent and a preparation method thereof. The absorbent contains the following raw materials: 1-10 parts of modified sponge, 5-15 parts of styrene, 15-40 parts of acrylics, 0.2-2 parts of functional monomer, 0.5-5 parts of emulgator, 0.2-2 parts of cross-linking agent, 0.1-1 part of initiator and 30-80 parts of water. The preparation process is as follows: adopting an emulsion polymerization method for preparing an emulsion type high oil-absorptive resin containing an epoxy functional group, and meanwhile, chemically modifying a polymeric sponge, grafting and compounding the emulsion type high oil-absorptive resin with the polymeric sponge, thereby acquiring the sponge loaded type organic solvent absorbent. The absorbent disclosed by the invention has the characteristics of polymeric sponge and oil-absorptive resin, has an excellent absorptive character, is free from obvious deformation after absorption and has a certain mechanical strength and flexibility; due to a specific high-porosity skeleton structure of the polymeric sponge, the osmotic resistance in practical application is small, a pore structure can be kept after absorption and the full contact of the wastewater effluent and absorbent is benefited; the industrial applicability is excellent; the development prospect is wide.

Description

technical field [0001] The invention belongs to the field of composite functional materials, relates to environmental pollution control technology, and more specifically relates to a sponge-loaded organic solvent absorbent and a preparation method thereof. Background technique [0002] With the rapid development of my country's chemical and pharmaceutical industries, various organic solvents are used more and more widely, and the emission of volatile organic compounds also increases, causing various environmental pollution problems and seriously affecting human life. and good health. Therefore, the treatment and recovery of VOCs emitted during the production process has attracted widespread attention. [0003] The absorption and adsorption method is simple to operate, has high removal efficiency and strong enrichment ability, and is a common method for dealing with organic solvent pollution. Oil-absorbing materials have been widely used to absorb organic solvents. Oil-abso...
