摘　　要：采用正交试验,考察发泡剂用量、发泡助剂用量、固化剂用量对缩合型泡沫硅橡胶拉伸强度、断裂伸长率、表观密度性能指标的影响,得到发泡硅橡胶的最优配方为基胶100份、发泡剂3份、发泡助剂2份、固化剂2.5份.利用扫描电子显微镜、万能机械拉力机、导热系数测定仪对几个配方样品进行结构和性能测试,结果表明:最优配方的样品其力学性能适中,内部微小气室分布致密均匀,具备较为理想的隔热保温性能.The effects of foaming agent,additive and curing agent content on tensile strength,rupture elongation and apparent density of foaming silicone were studied by the orthogonal experiment. The optimal formula for foaming silicone were 100 copies of base adhesives,3 copies of foaming agents,2 copies of additives,and 2. 5 copies of curing agents. The related mechanical properties and thermal properties of the above four formulae were investigated by scanning electron microscopy（ SEM）,multifunctional tensile machine,and hot disc instrument. Results presented that the optimum formula had moderate mechanical properties,well defined and dispersed inner pores,and desired thermal insulation performance.
