| 摘 要： | 诸城是我国重要的恐龙化石产地之一,化石丰富且保存完好,具有非常重要的科学价值。为保护好这一重要地质遗迹资源,增强化石保护的可行性和有效性,该文从恐龙化石防护材料角度入手,在大量试验基础上,研发制配了以甲基三乙氧基有机硅树脂以及氟碳树脂为主要原料,与纳米SiO_2共混形成的新型复合防护材料。试验结果表明,新型防护材料具有良好的抗紫外线、耐老化性和良好的热稳定性,可作为户外化石保护的优质材料。从恐龙化石保护效果看,涂膜透明性好,可保持化石原貌的真实性,同时能提高化石的防水性,增强耐热性和耐酸碱性。该材料在化石保护中具有良好的推广前景。

| 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. |
