A green sand-fixing agent of water-borne polymer,poly(vinyl acetate-butyl acrylate latex)(P(VAc-BA)),was synthesized and characterized.The influences of protective colloid,the amount of emulsifier and the emulsifier ratio m(SDBS)/m(Tween-60) on emulsion properties were discussed.With the sand soil as research object,the water retention,compressive strength,the tolerance of high temperature and water resistance of the sand-fixing agent were studied preliminarily.The results showed that when mass content of the protective colloid was 3%,mass content of the total emulsifier was 4% and the inner ratio 1:3,the visco-sity of the product was 155.40 mPa·s,and the product had a good thermal stability between 0~220 ℃ and a good sand fixation performance for practical application.
