摘　　要：研究了三种内衬纸用胶粘剂的物理特性,分析其在不同涂布量和环境水分活度条件下的胶粘效果变化,为胶粘剂的应用提供指导。研究结果表明:三种胶粘剂的水分含量、黏度、粒径均具备显著差异;随着胶粘剂涂布固形物含量的增加(0~2.0 mg/cm^2),铝箔纸的粘接强度呈现先增大后减少的趋势;三种胶粘剂的粘接强度峰值为1.0643~1.5972 N,涂布量均出现在1.30 mg/cm^2附近,但峰形宽窄和尖锐程度具备显著差异。这种变化规律将影响到胶粘剂的应用效果,可能与胶粘剂分子粒径和颗粒聚集相关。低和高环境平衡水分活度(0.113和0.809)均会提升铝箔纸的粘接强度,这可能与胶粘剂分子在不同水分活度环境下和纸基分子的分子间相互作用类别和强度变化有关,影响粘接效果。The physical properties of three kinds of adhesive for inner-lining paper were studied,and their adhesive effect changes under different coating amounts and environmental moisture activity were analyzed,in order to provide guidance for the application of adhesive.The research results showed that the water content,viscosity and particle size of three kinds of adhesive were significantly different.With the increase of adhesive coating solid content(0~2.0 mg/cm^2),the bonding strength of aluminum foil paper increased first and then decreased.The maximum bonding strength of three kinds of adhesive appeared from 1.0643 to 1.5972 N,all coating content appeared near 1.30 mg/cm^2,but the width and sharpness of the peak shape were significantly different.This change rule would affect the application performance of the adhesive,which may be related to molecule size and particle aggregation of the adhesive.Both low and high environmental equilibrium water activity(0.113 and 0.809)could improve the bonding strength of aluminum foil paper,which may be related to the type and strength change of the molecularinteraction between adhesive molecule and paper-based molecule in differentwateractivity environments,and affected the adhesive performance.
