一种具有净化空气功能的石材防护剂及制备方法和应用
摘要：
本发明公开了一种具有净化空气功能的石材防护剂及制备方法和应用，由下列重量份的原料组成：负载有贵金属的纳米二氧化钛4-8份、疏水纳米二氧化硅5-10份、分散剂240-300份、醇醚类溶剂1-5份、水240-300份。上述负载贵金属的纳米二氧化钛可以使得石材保护剂膜具有高效的净化空气的功能，上述疏水纳米二氧化硅使得石材保护剂膜具有很强的防水性和高强度性能，上述醇醚类溶剂提高了石材保护剂膜的附着力和耐久性。上述石材保护剂用于各类石材表面成膜后，通过纳米材料及溶剂等组分的协同作用，实现了膜层的纳米颗粒复合材料性能，使得该膜层具有高效净化空气、高强度、耐磨等性能。
摘要（英）：

The invention discloses a stone protecting agent with the air purifying function and a preparation method and application. The stone protecting agent is prepared from, by weight, 4-8 parts of nano titanium dioxide supported by precious metal, 5-10 parts of hydrophobic nano silicon dioxide, 240-300 parts of a dispersing agent, 1-5 parts of an alcohol ether solvent and 240-300 parts of water. By means of nano titanium dioxide supported by the precious metal, a stone protecting film can have the efficient air purifying function. The stone protecting agent film has strong waterproof performance and high strength due to hydrophobic nano silicon dioxide. The alcohol ether solvent improves adhesion force and durability of the stone protecting film. After the stone protecting agent is used on the surface of various kinds of stone and forms a film, due to the synergetic effect of the nano materials, the solvent and other components, nano particle composite material performance of a film layer is achieved, and accordingly the film layer has efficient air purifying performance, high strength and abrasion resistance.
