摘要

针对随行挂具在线脱塑的工艺及性能需求，研发出以苯甲醇和苯甲醛为主溶剂、乙二醇及醚为助溶剂、有机碱及无机碱为促进剂的新型高效脱塑剂，通过研究脱塑性能的影响因素确定了在线脱塑工艺的参数范围，并对脱塑不同阶段过程及机理进行了探讨。结果表明:塑粉涂层(厚度60 ～70 μm)在超声(频率40 kHz)条件下，脱塑温度60～75 ℃，促进剂浓度2.1～3.3 g/L 时，脱塑时间小于3 min；脱塑剂的挥发性较低，对板材的腐蚀性小，溶剂可回收再生；通过拆解塑粉涂层的网状高分子结构，逐层分散或溶解，最终达到彻底脱塑的效果，适用于随行挂具在线脱塑的应用场景。

Abstract

To meet the process and performance requirements for online deplasticization of accompanying hangers， a novel， highly efficient deplasticizer was developed.This agent， composed primarily of benzyl alcohol and benzaldehyde as the main solvents， ethylene glycol and ethers as co-solvents， and organic and inorganic bases as promoters， was studied.The factors affecting the deplasticization performance were examined， and the parameter range for the online deplasticization process was determined.The processes and mechanisms of deplasticization at different stages were also discussed.Results showed that under ultrasonic conditions (frequency of 40 kHz)， the time required for complete removal of the plastic powder coating (thickness of 60～70 μm) was found to be less than 3 minutes at 60～75 ℃and a promoter concentration of 2.1～3.3 g/L.The deplasticizer showed low volatility and low corrosiveness to sheet metal， and the solvent was recyclable and regenerable.The polymer network structure of the plastic powder coating was disassembled，and the coating was dispersed or dissolved layer by layer to completely remove the plastic coating.It was deemed suitable for the application scenario of online deplasticization of accompanying hangers.
