| titleOfInvention | A kind of preparation method of durable hydrophobic anti-photoaging stone cultural relic sealing coating |
| abstract | The invention belongs to the technical field of the preparation of novel anti-photoaging coatings for stone cultural relics, and provides a durable anti-aging coating for stone cultural relics, which has the disadvantages of poor durability, easy pollution, poor anti-photoaging performance, low strength and the like. The invention discloses a preparation method of a hydrophobic anti-photoaging stone cultural relic sealing coating. Add fluorosilane and nano-TiO 2 to the isopropanol solution for ultrasonic dispersion; prepare a mixed solution of PDMS and curing agent; dry the nano-TiO 2 grafted with fluorosilane and add it to the PDMS mixed solution, ultrasonically disperse it, and coat it on the surface. The surface of stone cultural relics is vacuumed and cured, which is the durable hydrophobic anti-photoaging stone cultural relic sealing coating. Due to the enrichment of nano-TiO 2 with light-shielding properties on the surface, the photoaging resistance is improved; the fluorosilane-modified nano-TiO 2 migrated to the surface reduces the surface energy of the coating, thus improving the hydrophobicity. The preparation method is simple and easy to operate, has a short period, is suitable for large-scale production, and is applied to the protection of stone cultural relics. |
