摘要
目的:比较不同SY-1硅橡胶被覆厚度的三明治硅橡胶结构的拉伸性能。方法:在相同条件下对表面被覆SY-1厚度分别为0mm,1mm,1.5mm,2mm的三明治式硅橡胶试件进行拉伸强度、扯断伸长率的测定,并对结果进行统计学分析。结果:被覆1mm SY-1硅橡胶的试件与单纯的GP-084泡沫硅橡胶试件拉伸强度及扯断伸长率的差异有显著性(p<0.05);被覆1.5mm SY-1试件与被覆1mm的SY-1试件的拉伸强度的差异无显著性(p>0.05),但是扯断伸长率的差异具有显著性(p<0.05);被覆2mmSY-1试件与被覆1mm SY-1试件的拉伸强度及扯断伸长率的差异有显著性(p<0.05)。结论:由SY-1硅橡胶和GP-084泡沫硅橡胶组成的三明治式结构可以明显增加泡沫硅橡胶较低的拉伸强度和扯断伸长率。
Objective： To measure the tensile properties of sandwich structure covered with different thickness of SY- 1 silicone elastomers.nethod： Tensile strength, elongation at break of sandwich structure silicone rubbers were measured. The samples of the sandwich structure were covered with different thickness （0mm, lmm, 1.5mm, 2mm） of SY-1 silicone elastomers. Data were analyzed by LSD-t test.Result-With the increase of the thickness of SY-1 silicone elastomers, the tensile properties of sandwich structure markedly enhanced.Conclusion： The sandwich structure can improve the low tensile properties of GP-084 Cellular Silicone Elastomer.
