Abstract
Sodium montmorillonite was organized by a series of alkyl quaternary ammonium to make an organic modified montmorillonite (OMMT). The organic montmorillonite-resorcinol-formaldehyde-latex (OMMT/RFL) film was prepared by introducing OMMT into RFL, and aging and curing later. The OMMT was valued by X-ray diffraction and Fourier Transform Infrared Spectroscopy (FTIR). The adhesion of the OMMT/RFL-coated fiberglass was evaluated using an H-adhesion technique. The mass-gain of OMMT/RFL and the tensile properties of the coated fiberglass were studied under different humidities. The results show that the best moisture resistance could be gained while 16MMT at 1.5 wt%. Compared with the tensile properties of RFL, the tensile strength of OMMT/RFL increases by 21.2%, the tensile modulus by 23.1% under humidity of 98%; the OMMT/RFL displays a better dynamic storage modulus at elevated temperature.
