摘　　要：主要以稀释剂乙二醇缩水甘油醚(AGE),环氧树脂(E51),固化剂腰果酚类(3008和6015型)3种物质进行实验,掺杂多种有色无机物,得到颜色丰富且性能优异的聚环氧树脂美缝剂。然后进行了红外、形貌观察、表面润湿性、硬度等的测定。结果表明:两种固化剂系列美缝剂产品在性能及易操作程度上,固化剂3008型与环氧树脂(E51)其固化速度及硬度更适合国标美缝剂技术要求,其3物质组成比(2∶5∶3)的聚环氧树脂美缝剂为最优者,表面平整,硬度在16.4 N左右,但是润湿性需要进一步探究。它们的颜色可自由搭配,有很强的装饰效果,便于操作,具有很好的应用前景。The colorful polyepoxy sealant with excellent properties is prepared with the epoxy resin(E51),curing agent cardanol(type 3008 and 6015)and diluent ethylene glycol diglycidyl ether(AGE)as key reactants by mixing a variety of colored inorganic substances.The FTIR,SEM,sur-face wettability,hardness and other properties determinations are carried out.The results show that compared with the combination of curing agent type 6015 and E51,the combination of type 3008 and E51 are more suitable for meeting the national technical standard of sealant.When the material ratio is 2∶5∶3,the surface is level and the hardness is about 16.4 N,but the wetting property needs to be further studied.Their color can be matched freely,achieving a strong decorative effect and an easy operation,which indicate that the sealant has a good application prospect.
