Abstract
A kind of silicone TQ resin was first synthesized with Dodecyltrimethoxysilane (WD10) and tetraethoxysilane (TEOS) by sol-gel method. And the RTV (Room Temperature Vulcanized) silicone rubbers using as-synthesized TQ silicone resins as filler were prepared. Thermal degradation and mechanical properties of these RTV silicone rubbers were studied by means of thermogravimetric analysis and tensile testing. The experimental results showed that both mechanical properties and thermal stabilities of RTV silicone rubbers were significantly improved by using the as-synthesized TQ silicone resins as filler. The RTV silicone rubber can be used to make the molds of architectural components ornamentation. The aim is not only to repair architectural components with decoration, but also for further study and research of ancient architectural conservation.
