【Abstract】 The research and preparation of styrene acrylate copolymer emulsion for fibers needlepunched nonwoven geotextiles was summarized. The relation between the level of flexible rigid monomers and elongation and strength of the geotexiles was discussed. At the same time, the effect of the presence of crosslinking agent on the thermal stabilization, elongation, strength of the geotexiles was studied in detail. Base on the above theory, the author proposes a optimum synthesis composition and reaction condition for the preparation of the emulsion.更多还原
