Abstract

The invention discloses a method for preparing oil absorption material via microwave radiation, which comprises adding water, disperser, inducer, cross linker and comonomer in a flask and even adding paper, mixing and dissolving at 50-95DEG C, adding mixing magnetons, mixing for 10min via a magnetic mixer, pouring solution into a reactionary pot, arranging into a microwave reaction chamber to react for 1-4h, washing and drying product. The invention can prepare honeycomb paper oil adsorption material, which comprises coating adhesive via a coating roller on one face of paper oil adsorption material, stacking when the coating faces toward one direction, aligning the coating distance, compressing paper, drying and solidifying. The invention can save half preparation time, while the prepared oil adsorption material has much pores, the specific area is higher than 2m2 / g and the oil adsorption is stronger than the resin synthesized by general method.

Description

technical field [0001] The invention relates to a method for preparing oil-absorbing smoke material by microwave. Background technique [0002] In recent years, oil fume pollution from the catering industry has become the third largest source of air pollution after industrial pollution and traffic pollution. The problem of oil fume pollution from the catering industry and disturbing residents has become one of the hot spots for urban residents' environmental protection complaints. Therefore, it is an urgent task to study efficient oil fume control technology. At present, the treatment of cooking oil fume is mainly electrostatic deposition method, but due to the high viscosity of the oil fume on the collector after cooling, it often makes collection and cleaning difficult, which increases the maintenance workload, and the oil and waste liquid after gravity flow and cleaning It may cause secondary pollution. The investment cost of electrostatic deposition equipment is relat...
