根据实验结果和理论分析业已确认,二烯类橡胶与金属粘接时使用的含官能团的含氯共聚物胶粘剂膜既能与二烯类橡胶分子链起化学反应,又能在金属表面上生成牢固的化学键,从而提高橡胶-金属粘合体系的粘接强度。共聚物中官能团含量的比例适宜时,会产生最高的粘接强度和高耐热性能。用此种偶联共聚物涂胶的钢丝帘线的粘接强度大于镀铜钢丝帘线的粘接强度。 According to the experimental results and theoretical analysis, it has been confirmed that the functional group-containing chlorine-containing copolymer adhesive film used when the diene rubber and the metal are bonded can both chemically react with the diene rubber molecular chain and form a solid on the metal surface Of the chemical bonds, thereby increasing the rubber - metal bonding system adhesive strength. When the proportion of functional group content in the copolymer is suitable, the highest adhesive strength and high heat resistance result. The bonding strength of the steel cord coated with such a coupling copolymer is greater than the bonding strength of the copper-plated steel cord.
