Problems solved by technology

[0007] The technical problem mainly solved by the present invention: Although the commonly used resin composite materials have good light weight, high strength and corrosion resistance, they still have the disadvantages of low hardness and poor wear resistance. It does not have antibacterial properties and high water absorption, which limits its use. It provides a method of crushing snake stomach, adding ammonium sulfate solution, filtering and dialysis overnight, mixing with the treated acrylic fiber waste, adding silver nitrate, shell Polysaccharides, polyethylene glycol and formaldehyde are heated and stirred under the condition that the air is completely exhausted, and then the materials are discharged, added with absolute ethanol to filter, rinsed with distilled water, and dried in an oven. The method of permanent antibacterial resin

Abstract

The invention discloses a method for preparing a superabsorbent antibacterial resin by using acrylic fiber waste, and belongs to the technical field of antibacterial resin preparation. In the present invention, ammonium sulfate solution is added after the snake stomach is crushed, filtered and dialyzed overnight, mixed with the treated acrylic fiber waste, silver nitrate, chitosan, polyethylene glycol and formaldehyde are added, and the temperature is raised under the condition that the air is completely discharged Stir, then discharge, add absolute ethanol to filter, rinse the filtrate with distilled water, put it into an oven for drying, and thus obtain a method for preparing a superabsorbent antibacterial resin by using acrylic fiber waste. Examples prove that the process of the present invention is simple and easy to control, using acrylic fiber waste as raw material, not only the cost of raw material is low, waste utilization is realized, but also the reaction condition is mild, so that the obtained resin composite material not only has high hardness, good wear resistance, but also It has remarkable antibacterial properties and high water absorption, and can be widely used in various fields such as industry, medicine, and life.

Description

technical field [0001] The invention discloses a method for preparing a superabsorbent antibacterial resin by using acrylic fiber waste, and belongs to the technical field of antibacterial resin preparation. Background technique [0002] Viruses, bacteria, and fungi can cause harm in all aspects of life. People are increasingly protected from infections caused by bacteria. Usually, antibacterial materials are added with one or more antibacterial agents to make the material have the ability to inhibit or kill bacteria. As human beings pay more attention to their own health, people's awareness of environmental protection is also increasing. For a long time, there are a large number of microorganisms in the living environment of human beings, which not only cause great harm to humans, animals and plants, but also cause the decomposition, deterioration, deterioration and corruption of various materials. [0003] Acrylic fiber, whose chemical composition is polyacrylonitrile, is...
