AI Technical Summary

Technical Problem

Traditional fabric tapes have insufficient wear resistance under long-term friction, high-frequency vibration or harsh environments, poor conductivity and triboelectric response, and poor compatibility between functional layers, which affects service life and performance optimization.

Method used

An ethylene-vinyl acetate copolymer core-shell emulsion is combined with a multifunctional finishing agent. Through core-layer polymerization and shell-layer crosslinking reaction, combined with nano-alumina and graphene/silver nanoparticle composites, a multifunctional layer structure with optimized wear resistance, conductivity and triboelectricity is formed.

Benefits of technology

It significantly improves the wear resistance and conductivity of the tape, enhances triboelectric response, ensures stability and compatibility between functional layers, and extends service life.

Abstract

The application belongs to the field of adhesive tape preparation and relates to a preparation method of wear-resistant cloth adhesive tape, which comprises the following steps: performing core layer polymerization reaction on ethylene and vinyl acetate under the action of an initiator; performing shell layer polymerization reaction on ethylene, butyl acrylate, diacetone acrylamide and vinyl acetate under the action of an initiator, and adding chain transfer agent and adipic acid dihydrazide to obtain ethylene-vinyl acetate copolymer core-shell emulsion; modifying nano-aluminum oxide in an ethanol aqueous solution through a silane coupling agent and polyethylene glycol to obtain modified nano-aluminum oxide; blending the modified nano-aluminum oxide with a graphene / silver nanoparticle composite, nano-zinc oxide, nano-silicon dioxide and a polyester plasticizer to obtain a multifunctional finishing agent; after pretreatment of cotton / polyester blended fabric, the ethylene-vinyl acetate copolymer core-shell emulsion is coated, and then the coated fabric is laminated with aramid non-woven fabric and dried, and then the multifunctional finishing agent is micro-embossed, and finally, the wear-resistant cloth adhesive tape is obtained through post-treatment, so that the wear-resistant life of the adhesive tape is significantly improved.
