Preparation and application of polyacrylate/rhodamine B composite latex by miniemulsion polymerization

In order to improve the stability of rhodamine B in water, polyacrylate/rhodamine B composite latex was prepared by miniemulsion polymerization and the property of polyacrylate/rhodamine B composite latex was also discussed. The particle size, Zeta potential, morphological structure and fluorescenct performance of rhodamine B solution and composite latex were tested by particle size analysis, transmission electron microscopy, X-ray diffractometry and fluorescence spectrometry, respectively. The influences of composite latex mass percent and binder mass percent on the fluorescent properties of cotton fabrics were discussed as application of polyacrylate/rhodamine B composite latex on the cotton fabrics by scraping. It is found that the average particle size and Zeta potential of polyacrylate/rhodamine B composite latex are 86.2 nm and -54.7 mV, respectively. The dispersion stability and fluorescent performance of composite latex are enhanced. The K/S values and fluorescent reflectance of cotton fabrics are higher, and the washing fastness and rubbing fastness reaches grade 4 and 3-4 under the condition of the mass percent of latex 10% and the binder mass percent of latex 20%, respectively.
