硫酸钙晶须是由生石膏制备而成的新型非金属材料。以硫酸钙晶须为填充剂,进行了配制环氧胶粘剂的研究。考察了硫酸钙晶须对环氧胶粘剂性能的影响,并与目前常用的几种填充剂进行比较。比较结果表明,其抗伸强度可提高50%~120%,剪切强度相对可提高40%~140%,效果明显。硫酸钙晶须是胶粘剂非常优良的填充剂。
Calcium sulphate whisker is a new nonmetal material prepared from gypsum. Research was carried out on preparing epoxy resin adhesive with calcium sulphate whisker as the filler, and the investigation on the effect of calcium sulphate whisker on the performances of epoxy resin adhesive was also made. The comparison with several commonly used fillers indicates that calcium sulphate whisker can improve the tensile strength by 50% - 120% and the shear strength by 40% - 140%, an evident effect, illustrating that it is very fine filler for adhesives.
