摘要:

随着供给侧改革的不断深入，创新驱动和新旧动能转换对新材料研制的需要越来越迫切。古生物化石保护意义重大。根据化石保护的特殊性，笔者所在团队通过大量的试验，研究出了一种新型防护材料——纳米SiO2改性甲基三乙氧基有机硅树脂。该文从化石保护效果、透气性、防紫外线、抗老化等方面，将纳米SiO2改性甲基三乙氧基有机硅树脂与FEVE氟碳树脂（氟烯烃乙烯基醚共聚物）进行了对比，认为纳米SiO2改性甲基三乙氧基有机硅树脂具有渗透性强，透气性好等特征，FEVE氟碳树脂的耐候性和抗腐蚀性比纳米SiO2改性甲基三乙氧基有机硅树脂略好。因此，以纳米SiO2改性甲基三乙氧基有机硅树脂为化石的底层防护材料，FEVE氟碳树脂为化石的表层防护材料，能对恐龙化石起到良好的保护效果。

Abstract:

Accompanying with the deepening of supply side reform, the need for innovation driven and new to old kinetic energy conversion for the development of new materials is becoming more and more urgent. Paleontological fossil conservation is of great significance. According to the particularity of fossil conservation, the latest protective material, nanoSiO2 modified methyl triethoxy organosilicon resin has been developed by our team through a large number of experiments. From the aspects of fossil protection effect, air permeability and antiultraviolet aging, cmparing nanoSiO2 modified methyl triethoxy organosilicon resin with FEVE fluorocarbon resin (fluoroolefin vinyl ether copolymer) , It is considered that nanoSiO2 modified methyl triethoxy organosilicon resin has the advantages of strong permeability and good air permeability, while the candidate and corrosion resistance of FEVE fluorocarbon resin are good. It is slightly better than nanoSiO2 modified methyl triethoxy silicone resin. Therefore, using nanoSiO2 modified methyl triethoxy silicone resin as the underlying protective material and FEVE fluorocarbon resin as the surface protective material of fossils can play a good protective effect on dinosaur fossils.
