Problems solved by technology

At present, a single chemical crosslinking agent is mostly used in the synthesis of super oil-absorbing resins, such as divinylbenzene, etc. The resulting resin has a perfect chemical crosslinking structure, which is neither soluble nor meltable, which brings great difficulties to the preparation of fibers.
However, the patent document (CN1584148A) requires step-by-step synthesis of polymers in the resin synthesis stage, and thermal cross-linking is required after fiber formation to form a chemical cross-linking structure. Wait

Abstract

The invention discloses a method for manufacturing organic liquid absorbing fibers, which comprises the following technical process: (1) preparing a terpolymer resin from a first monomer methacrylic acid n-butyl ester accounting for 55 to 75 percent of the total mass of monomers, a second monomer acrylonitrile accounting for 10 to 30 percent of the total mass of the monomers and a third monomer beta-hydroxyethyl methacrylate accounting for 15 percent of the total mass of the monomers, taking polyvinylalcohol accounting for 0.1 to 1 percent of the total mass of the monomers as a dispersing agent, and taking benzoyl peroxide accounting for 0.1 to 1 percent of the total mass of the monomers as an initiator; (2) fully drying the obtained terpolymer resin, uniformly mixing the dried terpolymerresin and a swelling agent dimethylacetylamide in an amount of 1 / 9 to 4 times mass of the terpolymer resin, standing at room temperature for 48 to 96 hours in a sealing way, and making the mixture fully swelled to form uniform gel; and (3) manufacturing the primary organic liquid absorbing fibers by a gel spinning method.

Description

technical field [0001] The invention relates to a technology for manufacturing functional fibers, in particular to a method for manufacturing organic liquid-absorbing fibers copolymerized with three monomers. Background technique [0002] In recent years, with the continuous development of world industry, the pollution of rivers and oceans caused by accidents of oil tankers and oil tanks and the discharge of oily waste water has posed a great threat to the environment and human life. Failure to solve these problems will cause serious harm to the earth and human beings. Greater destruction. Facing the deteriorating environment, it is imperative to study effective oil recovery technology and oily industrial wastewater purification materials. Therefore, the development of high-quality oil-absorbing materials has become a major research topic. [0003] Super oil-absorbing resin is a new type of polymer material successfully developed in recent years for waste oil treatment. It ...
