摘　　要：目的:研制邵氏硬度分别为26、28、30的复合型硅橡胶赝复材料,以满足特定缺损部位的赝复体硬度要求。方法:质量比均匀混合,加入适量的混合交联剂固化并加工成长方形试样。测试其邵氏硬度,选出硬度值最接近26、28、30的3种硅橡胶试样,确定相应的配方比例。结果:当SY复合型硅橡胶邵氏硬度为26.1±3.2、28.0±2.9、30.1±3.5时,SY-1和B硅橡胶的配方比例依次为82:18、79:21、76:24。结论:按照适当比例进行SY-1和B硅橡胶的并用,可以得到邵氏硬度为26、28、30的高邵氏硬度SY复合型硅橡胶赝复材料。Objective： To develop blending silicone elastomer with high Shore hardness, which fit especial facial prosthesis. Method： The base of SY-1 and B silicone elastomer was mixed at different mass ratio, and added proper quantity of mixed cross-linking agent and catalyst to base, then Shore hardness of the vulcanized specimens was measured and three mass ratios of these specimens whose Shore hardness was nearest to 26,28,30 were identified. Result： When the mass ratio of SY-1 and B silicone elastomer was 82： 18,79： 21,76：24 respectively, the hardness of vulcanized specimens was 26.1±3.2,28.0±2.9,30.1±3.5. Conclusion： Blending SY-1 and B silicone elastomer at proper mass ratio could obtain compound silicone elastomer with high hardness, which would fulfill the demands of restoration of different facial defect.
