Abstract
ABSTRACTFor the first time, the salt-resistant emulsion was applied as an ecological sand-fixing material to enhance the sand-fixing ability in salty desert. This study started from the synthesis of the novel salt-resistant poly(vinyl acetate-dibutyl maleate-acyclic acid-sodium p-styrene sulphonate) copolymer emulsion. Then, the structure, composition and thermal property of the emulsion were characterised. The sand-fixing properties and ecological effect of the emulsion were evaluated. The experimental results showed that the emulsion has been successful synthesised and could be used as an ecological sand-fixing material. The related reason is that, first, the emulsion could significantly visibly enhance the sand-fixing ability in high salt-affected sand land. Second, the prepared emulsion had good thermal aging resistance and freeze-thaw stabilities to withstand the changes in the temperature of salty desert, and the test of the influence of the emulsion on the growth of microbe of sand showed a favourable ecological effect.
