Method for preparing fibrous macromolecule adsorption material

Abstract

The invention discloses a method for preparing a fibrous macromolecule adsorption material. The method comprises the following specific steps of: preparing polymer silk from linear polymers, of which the molecular weight is 15,000-20,000, by a melting and spinning method; and then putting the polymer silk into a cross-linking agent and pore-forming agent solution at the temperature of 130-150 DEG C for 25-35 seconds to obtain the fibrous macromolecule adsorption material. The method adopts a novel preparation technology; a cross-linking layer is formed on the surface of a fiber through quick cross-linking, so that the strength of the fiber is guaranteed; the bonding force of the fiber on adsorbed molecules is improved through a pore-forming agent, the adsorption speed of the fiber is enhanced, and the adsorption capacity of the fiber is improved; the obtained fibrous macromolecule adsorption material meets the requirement on large adsorption capacity and long service life for industrial waste liquid treatment and quick response and high treatment speed for emergency accidents; therefore, the application field and the industrial application value of the fibrous adsorption material are expanded and improved.

Description

technical field

[0001] The invention relates to a manufacturing technology of an adsorption material, in particular to a preparation method of a fibrous polymer adsorption material, and belongs to the field of preparation of polymer materials. Background technique

[0002] With the development of industrialization, the problem of global environmental pollution is becoming more and more serious. Among them, organic waste liquids such as benzene, kerosene, gasoline, etc. , The pollution of rivers, oceans and other water resources caused by it needs to be curbed and solved urgently. The high oil-absorbing material has the advantage that the recovered organic liquid may be reused in solving the problem of organic waste liquid, which effectively saves resources and improves the utilization rate of resources. Therefore, vigorously developing high oil-absorbing materials is a research hotspot today.
