Abstract
Using sodium lignin sulfonate, urea, formaldehyde and Melamine as the main raw materials, a new type of environmentally-friendly sand fixing agent was synthesized to provide a new variety of sand fixing agent. The chemical composition analysis was carried out by FT-IR, the wind corrosion resistance, water retention, compressive strength and water resistance of sand fixing samples were measured, and the sand fixing effect of different concentration of sand fixing agents was analyzed. The results show that the new environmentally friendly sand fixation agent can bond the sand particles tightly to form a larger aggregate structure. The sand mold of the sand fixing agent sprayed 5%, the wind erosion rate of the sand fixing specimen reached 0.02 %, the water retention rate reached about 70 %, the compressive strength reached 25mm, and the water resistance reached 2.46 %, which can meet the actual application requirements.
