摘要
介绍了制备开孔硅橡胶泡沫的一种独特方法 ,该方法的工艺时间比传统的物理发泡时间短 ,具有更强的可操作性 ,减少了物理发泡剂的浪费 ,制备的泡沫开孔率与普通物理发泡的开孔型泡沫相当 ,与化学发泡制备的开孔型泡沫相比 ,泡孔细小均匀 ,且具有较小的压缩永久变形 (4 %～ 6 % )
A new method for preparing open-cells silicone rubber foam was introduced. The foaming period of modified method (MM) was less than that of conventional physical foaming(PF). The MM could be operated easily and reduced waste of the PF agent, and the opened-celled rate was as much as the rate of PF. The cells of MM were smaller and uniformer than those of the prepared open foam for chemical foaming and the permanent compressing set was small, 4%～6%.
