Study on the environmental performance of additional vinyl LSR

摘要：

The performance of additional vinyl liquid silicone rubber (LSR) were investigated based on accelerated aging test in different environment. The mechanical properties were studied in different experimental environments. Meanwhile, the cross-linking densities of the investigated samples were obtained by equilibrium swelling method. The article analyzed the changes of cross-linking density in different environments with time. The results showed that the tensile strength and elongation of vinyl LSR at high temperature and humidity conditions fluctuated gently, while the hardness increased greatly with time. The influence of salt spray corrosion on its performance was little, and its cross-linking density with its mechanical properties showed variation trend. The SEM image of the rubbers fracture topography showed that the cross-linking was compact and consistent.
