Problems solved by technology

The oil-absorbing fiber developed by the applicant's prior patent (CN1584148A) needs to synthesize polymers step by step in the resin synthesis stage, and needs to be thermally cross-linked after the fiber is formed to form a chemical cross-linked structure. The preparation process is cumbersome and complicated, and the obtained Fiber mechanical properties and flexibility are poor

preparation example Construction

[0014] The processing steps of organic matter adsorption fiber preparation method (hereinafter referred to as method) of the present invention are as follows:

[0015] 1. Add 0.1% to 1% of the total mass of the first monomer n-butyl methacrylate monomer and the second monomer acrylonitrile monomer into the reaction kettle The total volume ratio of the monomer and the second monomer acrylonitrile monomer is deionized water of 3:1. After fully dissolving, the first monomer n-butyl methacrylate monomer, the second monomer acrylonitrile The monomer and the initiator accounting for 0.1-1% of the total mass of the polymer monomer are placed in the same container, stirred into a uniform solution, then added to the reaction kettle, fed with nitrogen, stirred and heated to 70-80°C, and reacted for 2- After 6 hours, raise the reaction temperature to 80-90° C., continue the reaction for 2-4 hours, terminate the reaction, take out the product, wash and dry it, and obtain a white resin pro...

Embodiment 1

[0027] Only n-butyl methacrylate is used as the first monomer (that is, the acrylonitrile content of the second monomer is zero), benzoyl peroxide is used as the initiator, polyvinyl alcohol is used as the dispersant, distilled water is used as the reaction medium, and nitrogen protection Next, add the monomer solution containing 0.5% (accounting for the total mass of the monomer, the same below) initiator solution into the water dissolved with 0.5% dispersant, heat and stir at 73°C for 4h, raise the reaction temperature to 85°C and continue the reaction for 2h , terminate the reaction, wash, and dry to obtain a white granular resin; after the resin is fully dried, add an appropriate amount of solvent dimethylacetamide (the mass ratio of resin to solvent is 7:3) and mix evenly, and stir at 60-80°C 6 to 12 hours to form a uniform spinning solution. The spinning solution was allowed to stand for degassing for 2 hours, and the wet spinning method was used to coagulate in a coagul...

Embodiment 2

[0030] With n-butyl methacrylate as the first monomer, acrylonitrile as the second monomer, the mass ratio of the second monomer to the first monomer is 1:15, benzoyl peroxide as the initiator, polyethylene Alcohol is used as a dispersant, distilled water is used as a reaction medium, under the protection of nitrogen, the monomer solution containing 0.5% (accounting for the total mass of the monomer) of the initiator is added to the water in which 0.5% of the dispersant is dissolved, and heated and stirred at 73 ° C for 4 hours. Raise the reaction temperature to 85°C and continue the reaction for 2 hours, terminate the reaction, wash, and dry to obtain a white granular resin; after the resin is fully dried, add an appropriate amount of solvent dimethylacetamide (the mass ratio of resin to solvent is 3:2) Mix evenly and stir at 60-80°C for 6-12 hours to form a uniform spinning solution. The spinning solution was left to stand for degassing for 2 hours, and then extruded by a sc...

Abstract

The invention relates to a method for manufacturing organic-matter adsorbing fibers. The technical process includes that 1) first monomer n-butyl methacrylate covering 50-90 percent of the total mass of the two monomers (the same below) and 50-10 percent of second monomer acrylonitrile and 0.1-1 percent of dispersing agent, 0.1-1 percent of initiator and two types of deionized water (monomer total volume: 3:1) are used to produce resin; 2) proper amount of solvent and the achieved resin are used to prepare spinning stock-solution; 3) the achieved spinning stock-solution is used for spinning by solution spinning technology, and nascent fiber is achieved; 4) after stretching treatment of the nascent fiber, the organic-matter adsorbing fiber is achieved. The invention has the advantages of that the manufacturing technique is simple, the prepared fiber is in three-dimensional mesh texture, and the fiber has sound organic-matter adsorbing capacity and mechanical property.

Description

technical field [0001] The invention relates to a method for manufacturing functional fibers, in particular to a method for manufacturing poly-n-butyl methacrylate / acrylonitrile organic matter adsorption fibers prepared by solution spinning technology, and the international patent main classification number is intended to be Int.Cl. D01F 6 / 00 (2006.01) I. Background technique [0002] In recent years, the environmental pollution caused by oily sewage, waste gas liquid and leakage of oil tankers and oil tanks has become increasingly serious. 30% of the oil that pollutes the environment comes from industrial wastewater discharge, and 45% comes from oil tanker spills on the ocean. Facing the deteriorating environment, the research on effective oil recovery technology and oily industrial wastewater purification materials is imperative, and the development of high-quality oil-absorbing materials has become a major research topic. [0003] High oil-absorbing resin is a polymer w...
