硅泡沫压缩应力松弛影响因素的研究

Study on the effects on compression stress relaxation of HTV silicone rubber-foams

采用模压发泡成型技术制备了具有不同性能的硅泡沫,研究了影响硅泡沫压缩应力松弛性能的因素。结果表明:硅泡沫的密度、乙烯基硅油用量、泡孔结构和测试条件分别对硅泡沫材料的压缩应力松弛率都有明显的影响,但影响程度有所不同。

The silicone rubber-foams with different properties were prepared by the model-pressing foaming technology, and the effects on compression stress-strain performance of silicone rubber-foams were also studied. As a result, the density of foams, and dosage of vinyl silicone oil, and cellular structure and testing condition had different important effects on compression stress-strain performance of silicone rubber-foams.
