摘　　要： 用多元乳液共聚法制备了用于粘贴导静电PVC地板胶粘剂 ,加入乙炔炭黑赋予乳液胶粘剂导静电性能。研究了影响粘接强度和初粘力的主要因素 ,确定m (VAc)∶m (BA +VAc)为 1∶3;研究了乳化剂和交联单体对乳液性能的影响 ,研究得出 ,适量加入AA和NMAM可以减少乳化剂的用量 ,提高乳液的性能。研究表明 ,乙炔炭黑加入量越大 ,导静电性能越好。得到的导静电乳液胶粘剂粘接强度达到 0 .5 1MPa以上 ,导静电性可达到 7.2×10 3 Ω ,2项指标均超过国家标准。 Using emulsion copolymerization technique the emulsion adhesive used for static conducting PVC flooring was prepared and endued with static conductibility by introducing acetylene black.Investigation for the effect of main factors on bonding strength and tack of the adhesive determined that m (VAc)∶ m (BA+VAc) was 1∶3.The results for the effect of emulsifier and cross-linking monomers on emulsion properties showed that addition of AA and NMAM in proper amount can decrease the emulsifier amount and increase the emulsion properties.The more acetylene black amount was,the better static conductivity was.The bonding strength and static conductivity of the adhesive were reached to be 0.51 MPa and 7.2×10 3Ω,respectively,which were better than the indexes of the national standard.
