【 摘 要 】

The coating material used for the manufacture of polyurethane paint with the addition of bentonite into the matrix can improve thermal capability. The purpose of this study is to produce new material namely hybrid bentonite-chitosan which can be used as a filler for the manufacture of polyurethane paint, chitosan intercalation process into bentonite interlayer and increase the concentration of surfactant against the opening of bentonite interlayer. By varying the CEC of cationic surfactants (0.7 CEC, 1 CEC, and 1.3 CEC) and CEC anionic surfactants (0.1 CEC, 0.2 CEC and 0.3 CEC) to obtain the highest basal spacing, structure, and morphology, several characterization procedures have been carried out. From the results of interlayer bentonite analysis with modification of cationic and anionic surfactants using XRD (X-Ray Diffraction) an increase in basal spacing from 14.18393 Å to 23,00023 Å. While the FTIR (Fourier Transform Infrared) chemical structure of hybrid bentonite-chitosan at a wavelength of2800 cm-1 shows the C-H group, 1025 cm-1 shows the C-O group and polyurethane in the -OH absorption (3445 cm-1 ). This study can produce hybrid bentonite-chitosan material as a filler in the manufacture of polyurethane paint.
