Abstract:Acrylate emulsion pressure-sensitive adhesive (PSA) is a kind of environmentally friendly adhesive with low content of VOC application.In this study, A glucose based emulsifier - butyl glucoside maleate (BGMAH) were synthesized . and its promotion effect in the emulsion polymerization of acrylic emulsion PSA was investigated. The PSA modified by BGMAH was prepared by semi - continuous seed emulsion polymerization. The effect of structure and amount of BGMAH on the water resistance and adhesion of the latex film were studied.The results showed that when the mass fraction of the composite emulsifier was kept at 3%, m (BGMAH): m (OP-10): m (SDS) = 2: 1.5: 0.5, the adhesive property and water resistance of the latex film were the highest. The results of Fourier transform infrared spectroscopy (FTIR) shows that cross-linking reaction was happened in the modification of acrylic emulsion PSA. The results of differential scanning calorimetry (DSC) shows that the modified polymer system has good compatibility and the glass transition of latex film was greatly reduced. And the thermal stability of the latex films was improved by thermogravimetric analysis. The reaction mechanism of polymerization was also investigated.
