以丙烯酸酯单体作为主要原料、耐热添加剂[如苯乙烯-丁二烯-苯乙烯弹性体(SBS)、聚乙烯丙烯酸酯橡胶(AEM)、氟橡胶(FKM)和氯磺化聚氯乙烯(CSM)等]作为厌氧结构胶的改性剂,制备双组分非混合型耐热厌氧结构胶,并采用单因素试验法优选出制备该厌氧结构胶的最佳工艺条件。结果表明:当混合单体为甲基丙烯酸环己酯/三环癸烷二甲醇二丙烯酸酯、耐热添加剂为AEM且w(AEM)=20%时,厌氧结构胶的综合性能相对最好;该厌氧结构胶可在150℃以下长期使用、200℃时短期使用,并具有良好强度和韧性;此外,该厌氧结构胶的耐溶剂性能优良,可在高温条件下进行粘接,具有良好的应用前景。
Acrylate monomer as the main raw material, heat-resistant additives such as styrene-butadiene-styrene elastomer (SBS), polyethylene acrylate rubber (AEM), fluorine rubber (FKM) and chlorosulfonated polyvinyl chloride (CSM), etc.] as anaerobic structural adhesive modifier to prepare a two-component non-mixed heat-resistant anaerobic structural adhesive, and the optimum process conditions for preparing the anaerobic structural adhesive by single factor test method. The results show that when the mixed monomer is cyclohexyl methacrylate / tricyclodecane dimethanol diacrylate and the heat-resistant additive is AEM and w (AEM) = 20%, the overall performance of anaerobic structural adhesive is relatively best ; The anaerobic structural adhesive can be long-term use below 150 ° C, short-term use at 200 ° C, and has good strength and toughness; In addition, the anaerobic structural adhesive excellent solvent resistance, high temperature bonding conditions, with Good application prospects.
