- 摘要:
- 探讨了辐照交联技术应用在三元乙丙橡胶/天然橡胶共混胶中时硫化剂用量与辐射吸收剂量的优化设计问题。通过将硫化剂用量与辐射吸收剂量的组合形成不同的交联方案，对不同交联方案下共混胶性能的测试结果采用回归分析的方法得到硫化剂用量和辐射吸收剂量与100%定伸应力、拉伸强度和扯断伸长率的回归方程，根据回归方程通过可视化模拟作出直观的二维等高线图和三维曲面图，并经由优化交联组合方案对回归分析结果进行了验证。结果表明，硫化剂增量系数和辐射吸收剂量的增大都能使共混胶的弹性模量增大，导致其100%定伸应力呈增大趋势、扯断伸长率呈减小趋势；随着硫化剂用量和辐射吸收剂量的增大，拉伸强度表现为先增大然后逐渐减小。高硫化剂用量-低辐射吸收剂量方案适合于制备对模量和强度要求较高的橡胶材料，而低硫化剂用量-高辐射吸收剂量方案适合于对扯断伸长率和耐老化性能要求较高材料。
- Abstract:
- The optimal design of curing agent amount and radiation absorbed dose in application of radiation crosslinking technology for ethylene-propylene-diene rubber / natural rubber blends was discussed. By combining the amount of curing agent and radiation absorbed dose to form different crosslinking schemes, regression equations between the curing agent amount and radiation absorbed dose and modulus at 100%, tensile strength and elongation at break were obtained by regression analysis of test results of the blend properties under different crosslinking schemes. According to the regression equations, 2-dimensional contour diagram and 3-dimensional surface diagram were displayed through visual simulation, and the results of regression ana-lysis were verified by optimizing crosslinking combination schemes. The results showed that the increase of increment coefficient of curing agent and radiation absorbed dose could increase elastic modulus of the blend, leading to an increase in modulus at 100% and a decrease in elongation at break. With the increase of curing agent amount and radiation absorbed dose, tensile strength of the blend first increased and then gradually decreased. The scheme of high curing agent amount with low radiation absorbed dose was suitable for preparing rubber materials with high requirements on modulus and strength, while the low curing agent amount with high radiation absorbed dose scheme was suitable for materials with high requirements on elongation at break and aging resistance.
