Abstract

In order to solve the problem that the toughness (impact strength) of the traditional elastomer toughening will decrease its rigidity (modulus) while improving the toughness (impact strength) of the material, the multi-porous nano-cacO3/polymer composite and its application in building plastics were proposed. In this essay, the mechanical properties of nano-caco3/PVC/CPE and nano-caco3/PP/SBS composites are studied. The results showed that the notch impact strength increased by 15.8 % from 46.8 kJ/m2 to 54.2kJ/m2 when two nano-cacO3 was added into the PP/SBS blend system, indicating that nano-cacO3 also toughened PP to some extent.

Conclusion

Nano Ca-CO3 has remarkable toughening effect on PVC blending system, and also has certain toughening effect on PP blending system. The profile with nano-cacO3 added can ensure the impact performance of low temperature drop hammer, while the notched impact strength, tensile strength, elongation at break and flexural modulus of the simply supported beam are significantly improved compared with the profile without nano-cacO3 added. The application of nano CaCO3/PVC/CPE composites in the profile of PVC doors and Windows is studied.

多级多孔聚合物纳米复合材料的制备及其在建筑设计中的应用

为了解决传统弹性体增韧在提高材料韧性（冲击强度）的同时会降低其刚性（模量）的问题，提出了多孔纳米-caco3/聚合物复合材料及其在建筑塑料中的应用。本文研究了纳米-caco3/PVC/CPE 和纳米-caco3/PP/SBS 复合材料的力学性能。结果表明，在 PP/SBS 共混体系中加入两种纳米 CacO3 时，缺口冲击强度从 46.8 kJ/m2 提高到 54.2kJ/m2，提高了 15.8%，这表明纳米 CacO3 也在一定程度上增韧了 PP。添加了纳米 Ca-CO3 的型材能保证低温落锤的冲击性能，与未添加纳米 Ca-CO3 的型材相比，简支梁的缺口冲击强度、拉伸强度、断裂伸长率和弯曲模量都有显著提高。研究了纳米 CaCO3/PVC/CPE 复合材料在 PVC 门窗型材中的应用。
