摘　　要：通过TCCA/MEK溶剂型卤化法处理天然橡胶(NR),以解决其表面能低、粘接性能差的问题,并探讨了T型剥离强度确定最佳处理工艺。研究结果表明:T型剥离强度确定最佳处理工艺为,先将NR打磨,在室温下表面涂覆,w(TCCA)=15%(相对于TCCA/MEK溶液质量而言),且处理时间20 min;用801强力胶粘接处理后的NR,T型剥离强度可达到2.85 N/mm,破坏方式为内聚破坏。Natural rubber(NR)was treated by TCCA/MEK solvent based halogenation method,in order to solve the problems of low surface energy and poor bonding property.And the T-type peel strength was discussed to determine the optimal treatment process.The research results showed that the optimal treatment process determined by T-type peel strength was to polish the NR first,and then coat the surface at room temperature,w(TCCA)=15%(relative to the mass of TCCA/MEK solution),and the treatment time was 20 min.After bonding treatment by super adhesive 801,the T-type peel strength of NR could reach 2.85 N/mm,and the failure mode was cohesive failure.
