Embodiment 1

[0035] The ternary copolymer resin is synthesized by aqueous phase suspension polymerization. The specific process is: add a certain volume of deionized water (deionized water volume: monomer total volume = 3: 1) and dispersant polyvinyl alcohol (accounting for unit volume) in the polymerization kettle. 0.5wt% of the total mass of the body), so that it is fully dissolved; then methyl methacrylate, n-butyl methacrylate, crosslinking agent β hydroxyethyl methacrylate (MMA: BMA=10: 90; MMA+BMA: HEMA=90: 10) and initiator benzoyl peroxide (accounting for 0.5wt% of monomer gross mass) add in the beaker, stir until forming uniform solution, then this solution is added in the reactor, Introduce nitrogen, stir and heat up to the reaction temperature of 85°C. After reacting for 5 hours, raise the reaction temperature to 95°C. After continuing the reaction for 1 hour, terminate the reaction, take out the product, wash and dry to obtain a white granular resin.

Abstract

The invention discloses an absorbing fiber and a manufacturing method thereof. The absorbing fiber comprises 100wt% of polymer monomer by mass percent, wherein n-butyl methacrylate monomer accounts for 70-90wt%, and methyl methacrylate monomer accounts for 10-30wt%; beta-hydroxyethyl methacrylate accounts for 10-20wt% of the polymer monomer (the following are the same); and benzoperoxide accounts for 0.1-0.5wt% of the total mass of the polymer monomer. The manufacturing method adopting the mass percent composition of the absorbing fiber comprises the following steps: 1, refining the methyl methacrylate and the n-butyl methacrylate in a reduced pressure distillation mode; 2, synthesizing methyl methacrylate / n-butyl methacrylate / beta-hydroxyethyl methacrylate multipolymer by using a water-phase suspension polymerizing method; 3 thoroughly drying the multipolymer, and adding 30-50wt% of N,N-dimethyl acetamide solvent according to the mass ratio of 3:7-1:1 to sufficiently swell the multipolymer for 24-48 hours; and 4 under the spinning temperature of 100-150 DEG C, preparing the absorbing fiber by using a gel spinning method and a double-screw spinning machine.

Description

technical field [0001] The invention relates to a functional fiber manufacturing technology, in particular to an adsorption fiber with the function of absorbing organic liquid and a manufacturing method thereof. Background technique [0002] At present, organic waste liquid has caused more and more serious pollution to the living environment of human beings, threatening the balance of the entire ecosystem. The outstanding advantages of high oil-absorbing materials in solving the problem of organic waste liquid are: the recovered organic liquid may be reused, which effectively saves resources and improves the utilization rate of resources. Therefore, vigorously developing high oil-absorbing materials is a research hotspot today. [0003] Super oil-absorbing resin is a kind of low-crosslinking polymer with lipophilic monomer as the basic monomer, and its oil absorption mechanism is similar to that of super water-absorbing resin. Compared with traditional oil-absorbing materi...
