摘要 目的 测试SY -1硅橡胶在多种外源性染色剂中的颜色稳定性。方法 将SY -1硅橡胶试件浸泡在几种常见的染色试剂中 ,应用美能达CS -3 2 1便携式色差仪分别测试出浸泡前和浸泡后 1、2、3、4周的色度值 ,利用色差公式计算出试件的色差值 ,并与国外同类产品MDX4-4 2 10进行对照。结果 不同外源性染色剂对硅橡胶有不同的影响。随着染色时间的延长 ,不同染色剂对硅橡胶的染色程度不同。结论 硅橡胶的色彩稳定性与外源性着色剂的种类 ,作用时间及自身特性相关。SY -1硅橡胶的色彩稳定性与MDX4-4 2 Objective To evaluate the color stability of SY-1 silicone elastomers immersed in coloring agent. Method SY-1 silicone elastomers were respectively dipped in some common coloring agent. 0, 1, 2, 3, 4 week after dipped, the chromatic value was measured with Minolta portable chromalicity inetrument(CS-321) and compared with
