An epoxy silane, a new kind of ambient temperature crosslinker for acrylate copolymer soap-free hydrosol is introduced. Some factors affecting the stability of the microemulsion such as kind and content of emulsifiers, content of KH-560 have been studied. When ω(OP-10)=5% and ω(KH-560)=40%, a stable microemulsion is obtained. The shelf stability of curable emulsion comprising of hydrosol is longer than 6 months at room temperature(content of microemulsion is 5%), crosslinking degree of the film is 93% and the film has good resistance to water(swelling ratio decreases by 83%) swelling ratio of 115% in toluene.
