摘 要:采用双酚s与环氧氯丙烷在碱性条件下反应,合成双酚s型环氧树脂并以其为主体树脂配成胶黏剂。用红外光谱进行了表征。考察了反应条件(包括反应温度、碱液浓度、反应时间、反应物配比等)对胶黏剂性能的影响。结果表明:双酚s:环氧氯丙烷(物质的量比)为1:5时,产物为固体,双酚s:环氧氯丙烷(物质的量比)为1:10时产物为半固体,双酚s:环氧氯丙烷(物质的量比)为1:15和1:20时产物为液体,催化剂质量分数为25%-35%,在90-100℃,反应8~9h,所得胶黏剂剪切强度可达16.8MPa。The bisphenol-S epoxy resin is synthesized by the reaction between 4,4'-dihydroxydiphenyl sulfone and epichlorohydrin under alkaline condition. Then it is used as a matrix resin to prepare an adhesive. The structure is characterized by IR. The effects of reaetion conditions on the performances of adhesive are studied, such as reaction temperature and time, the concentration of alkaline liquor and the ratio of reactant. The results show that the products will be solid when the molar ratio of 4,4'-dihydroxydiphenyl sulfone to epichlorohydrin is 1:5; when the molar ratio is 1:10, the products will be semisolid; and the products will be liquid when the molar ratio is 1:15 and 1:20. The shear strength of adhesive will reach 16.8MPa when the reaction temperature is 90-100℃, reaction time is 8-9h and the eoneentration of catalyst is 25%~35%.
