Abstract:Zhucheng city is one of the important sites of dinosaur fossils in China. Fossils in this area are abundant and well preserved with great scientific value. In order to protect the important geological relic resource and enhance the feasibility and effectiveness of fossil conservation, from the aspect of protective materials of dinosaur fossil, on the basis of a large number of experiments, a new type of composite protective material has been prepared by blending methyl triethoxy silicone resin and fluorocarbon resin with nanoSiO2. As showed by the test results, the new protective material has good antiultraviolet aging resistance and thermal stability, and can be used as outdoor fossil protection material. From the protection effect of dinosaur fossils, the film has good transparency. It can truly reflect the original appearance of fossils, improve the waterproof of fossils, enhance heat resistance and acid and alkali resistance. This material has good prospects for popularization in fossil protection.
