摘要
首次采用液体聚硫橡胶制成预聚体再高温硫化成型,压制新型聚硫橡胶密封帽制品。由于该制品要求有较高的硬度、拉伸强度、撕裂强度及外观要求,研究发现配合剂类别和水平有显著影响。研究了硬脂酸盐对聚硫橡胶预聚体硫化后硬度、撕裂强度、拉伸强度及压制成型工艺性等性能的影响。结果表明,硬脂酸盐的加入量控制在一定范围之内,能够有效地改善聚硫橡胶预聚体压制成型工艺性并能显著地提高聚硫橡胶预聚体硫化后的力学性能。
Adopted liquid polysulfide prepolymer cured at high temperature for sealing cap at the first time.High hardness,high strength and appearance was needed.We emphasized to study the effect of stearate on mechanical properties of polysulfide prepolymer.It was found that the quantity of stearate was important.When the quantity in some range,technologic property improved and mechanical properties of polysulfide prepolymer increased.
