Preparation method for composite high oil-absorption resin

Abstract

Relating to the high oil-absorption resin preparation field, the invention discloses a preparation method for a composite high oil-absorption resin. The method includes: (1) preparation of immobilized microbial microspheres: mixing modified mussel shell powder with a seed bacterial liquid, adding a sodium alginate solution into a bacteria adsorbing modified mussel shell powder solution, then injecting the mixed solution into a calcium chloride solution and conducting dispersion into balls, and conducting crosslinking to obtain immobilized microbial microspheres; (2) preparation of an acrylate copolymer emulsion: adding a methylacrylate monomer, styrene, an initiator and an emulsifier into water and conducting stirring emulsification; adding a crosslinking agent and a pore making agent into the emulsion to carry out reaction so as to obtain an acrylate copolymer emulsion; and (3) preparation of composite high oil-absorption resin: adding immobilized microbial microspheres, a coupling agent and cellulose into the acrylate copolymer emulsion, conducting stirring and then performing vacuum drying, thus obtaining the composite high oil-absorption resin. The composite high oil-absorption resin prepared by the method provided by the invention has fast oil absorption speed and large oil absorption capacity, and can carry out microbial degradation on oil.

Description

technical field [0001] The invention relates to the field of preparation of super oil-absorbing resins, in particular to a preparation method of composite super oil-absorbing resins. Background technique [0002] In the past few decades, my country's industry has developed rapidly and the living standards of the people have been continuously improved. However, with the development of industry, the pollution of industry to the environment has become more and more serious. In recent years, people's awareness of environmental protection has gradually strengthened, and the government has paid more and more attention to environmental governance. [0003] Among the many sources of pollution, the problem of water pollution is particularly prominent. Among them, the leakage and discharge of industrial oil have caused huge pollution to oceans and rivers, posing a serious threat to the environment. [0004] At present, oil-absorbing materials are generally used to absorb oil in water...
