【Abstract】 Silicon sol was prepared by traditional silicon metho d, and Na 2SiO 3 nanoparticles (size in 10～20?nm) aqueous dispersion was prepa red with its surface modified by oligomer with soap-free polymerization. With n anosized sodium silicate, maleic anhydride and acrylate as major materials, a ne w type of inorganic-organic complex nonphosphate detergent builder with low cos t and good properties was prepared in the following.The study of properties of t he builder influenced by the preparation and the surface-modifying processes of the nanoparticles was made.更多还原
