一、引言 6101环氧树脂是一种浅琥色液态环氧树脂,它具有很高粘结性能,能很好的粘结金属、陶瓷、半导体和其它材料。这种树脂加固化剂后可在室温下固化,固化后的树脂的化学稳定性、电学性能和机械性能都很好,因此这种树脂使用广范。除此,它还具有较好的红外透过性能,在1.9～2.5微米、2.9～4.2微米、4.4～5微米和8～14微米波段的红外透过率在60％以上,最大可达90％,因此它又是一种较理想的供2～14微米波段使用的粘结材料。6101环氧树脂在液态情况下对可见光的透过率虽较好,但一般 I. INTRODUCTION 6101 Epoxy resin is a kind of light-colored liquid epoxy resin, which has high adhesion and can well bond metal, ceramics, semiconductors and other materials. The resin curing agent at room temperature after curing, the cured resin chemical stability, electrical properties and mechanical properties are good, so the use of this resin wide range. In addition, it has good infrared transmission performance, and the infrared transmittance of more than 60% at 1.9-2.5μm, 2.9-4.2μm, 4.4-5μm and 8-14μm bands can reach 90% , So it is a more ideal binder for use in the 2-14 micron band. 6101 Epoxy resin in the case of visible light transmittance is better, but in general
