填料加入高聚物中会引起高聚物结构的变异,从而影响其力学性能。高聚物补强的基础理论的研究从理论或实用方面都是具有重要意义的课题。国外虽已做了大量工作研究橡胶的补强理论,但到目前在许多关键问题上仍有争论。硅橡胶的机械强度极大地依赖于补强填料的性质和数量,更加其不发生微晶的“自补强”效应,不易老化,配方简单等因素,显然是 Filler added to the polymer will cause the polymer structure variation, thus affecting its mechanical properties. The research on the basic theory of polymer reinforcement is of great significance both theoretically and practically. Although foreign countries have done a great deal of work to study the theory of rubber reinforcement, there are still many controversies on many key issues so far. The mechanical strength of silicone rubber greatly depends on the nature and quantity of reinforcing fillers, and more it does not occur “self-reinforcing” effect of microcrystalline, not easy to aging, simple formula and other factors, obviously
