AI Technical Summary

Technical Problem

Existing chemical recycling technologies are unable to efficiently and cost-effectively remove the adhesive residue from ultra-high molecular weight polyethylene fiber waste, resulting in a decline in fiber recycling performance, and traditional solvents may cause environmental pollution.

Method used

Using biodegradable ionic liquids and organic bases as solvents and catalysts, the adhesive on the fiber surface is penetrated, swollen and peeled off through the synergistic effect of the compounded ionic liquids and organic bases, and ultrasonic cleaning is combined to achieve efficient adhesive removal.

Benefits of technology

It achieves efficient degumming under mild conditions, with fiber gluing content below 2wt%, making it green and environmentally friendly. It reduces the risk of fiber performance damage and environmental pollution, and promotes the high-value recycling of fibers.

Abstract

The application belongs to the technical field of polymer material recycling, and particularly relates to a green degumming agent for ultra-high molecular weight polyethylene fiber scraps and a degumming method. The green degumming agent for ultra-high molecular weight polyethylene fiber scraps comprises the following components: 60-80 parts of biodegradable ionic liquid, 5-10 parts of catalyst organic base and 10-35 parts of deionized water. The degumming agent is green, environmentally friendly, non-polluting and reusable. The degumming condition is mild, the operation is simple, the degumming rate is greater than 90%, the glue content of the recycled fiber is less than 2wt%, and the high-value recycling of the ultra-high molecular weight polyethylene fiber is facilitated.
