Abstract:N,N,N-tris(triethoxysilylpropyl) melamine was prepared by using polychlorostyrene as a skeleton and grafting with aminosiloxane KH-550 was used to paper culture heritage treatment. The heat aging test was used to evaluate the changes of pH value, tensile strength, alkaline residue and the fiber breaking percentage of the paper before and after treatment. Results showed that the pH value increased from 3.2 to 7.7~7.8, the tensile strength also increased from 915 N/m to 1300 N/m. Furthermore, the colour change in appearance (ΔE*=1.72) was slight. The heat aging tests indicated that the pH value of treated paper can stabilize in neutral or slight alkaline and also the tensile strength is kept in ~1200 N/m. Compared with the untreated paper, the paper treated with N,N,N-tris(triethoxysilylpropyl) melamine can effectively decrease its aging rate.
