石材防护剂（Stone protective agent） Nanometer is one of the objective fields for people to understand the world. Nanometer is one of the units of scale, 1 nanometer =10m=10A. Nano materials refers to the at least one dimension in nanometer scale or with them as the basic unit structure, and has special physical and chemical properties of the material, usually it has four effects, namely, small size effect, macroscopic quantum tunneling effect, surface effect and interface effect, which has the unusual changes in optics, mechanical and electrical properties. Nano materials and its technology are important contents of new material field in Chinas high technology development program (863 plan). Nano materials have become science formally in the late 80s and early 90s. At present, nano material science is the frontier and hotspot of science and technology in the world. All countries in the world regard it as an important content of high and new technology research program. Tsien Hsueshen, a famous physicist, predicted in 1991 that the structure of nano and nano will be the focus of the next stage of scientific and technological development. It will be a technological revolution and will be another revolution in twenty-first Century. In recent years, a new concept in China and nanostructured materials research group, assistant chief scientist of Chinese Academy of Sciences, Institute of chemistry Jiang Lei first proposed the two co nano interface material, the functional materials research to a new level, and obtain some meaningful results. Nano protective agent is used as the theoretical basis, using the unique nano effect of nano materials, especially nano surface effect, and developed into a new super biphobic nano interface material, protective agent can improve the performance of the various surface usually protective material. The surface properties of metal, plastic, chemical fiber fabric material has been developed. The nano metal surface protection agent, plastic surf
