Research on Dispersing Properties of Nano-materials in Latex Paints

The dispersing property and UV-proof property of nano-materials (such as nano-TiO2, nano-SiO2-x) in latex paints were studied. The relationship between nano-materials and coating property was analyzed. The coatings containing nanomaterials was prepared by processing nano-particles with special agents and proper dispersing process. The results show that the key for nano-coating to become an industrialized product is the effective dispersing and stable storing of nano-materials in the coatings. The results also show that the latex paints containing 0. 4% nano-TiO2 can effectively improve the synthetic properties, . especially the shielding property of coatings.
