【摘要】 采用自制的六亚甲基四胺-间苯二酚络合物与KH-550,A-151两种硅烷偶联剂以及其他助剂等制备了可用于氟橡胶与金属粘接的FM胶黏剂,与Chemlok 607胶黏剂和合神FA-1胶黏剂进行了胺类硫化的氟橡胶与钢粘接的对比实验,研究了粘接机理。结果表明:等摩尔比的六亚甲基四胺-间苯二酚络合物是优良的粘合促进剂,所制备的FM胶黏剂用于胺类硫化的氟橡胶与钢粘接时平均拉剪强度大于5MPa,最高可达6.28MPa,综合性能优于Chemlok 607和合神FA-1。络合物分解生成具有活性亚甲基的物质,促进氟橡胶与硅烷偶联剂生成化学键,同时,这些活性物质在硫化过程中生成多种具有氮亚甲基结构特征的、含有大量活性基(—OH)的氨基树脂,提高了与金属的粘接力。更多还原

【Abstract】 Adhesion between metal and fluorine rubber is a difficult problem.The objective of this work was to improve adhesion properties in bonding metal with fluorine rubber.Prepared the complex from urotropine and resorcinol,adopted two kinds of silane coupling agents KH-560,A-151 and other agent developed FM adhesive,compared with Chemlok 607 adhesive and FA-1 adhesives in bonding steel to fluorine rubber vulcanized by amine compound at the same experimental conditions.The result showed that 1∶1 complex formed between urotropine and resorcinol is an ideal accelerant agent for FM adhesive in bonding steel to fluorine rubber vulcanized by amine compound,its property in shear by tension loading exceeds 5MPa,can achieve 6.28MPa,that is superior to Chemlok 607 and FA-1.The complex decomposes activated substances with methylene,can promote formation the chemical bond between fluorine rubber and silane coupling agent;meanwhile,these activated substances can produce many kinds of amino resin containing a large number of activated function(-OH) in the course of vulcanization,and improves adhesion forces with metal.更多还原
