Embodiment 1
[0030] Road composite water stabilizer, the preparation raw materials include solid waste, cement and soil stabilizer;
[0031] Among them, the internal mixing amount of cement (42.5po ordinary Portland cement without R) is 5%, and the external mixing amount of soil curing agent is 0.014%;
[0032] Soil stabilizer, including: 30 parts of papermaking sludge, 15 parts of slag powder, 32 parts of sodium polyacrylate, 36 parts of glycerol, 26 parts of sulfonated oil, 18 parts of activator, 9 parts of oxidant, 10 parts of dispersant, high 2 parts of molecular additives, 0.6 parts of surfactant, 4 parts of lignin fiber, 10 parts of aminosilanol, 5 parts of water absorbent;
[0033] The specific preparation method of the soil solidifying agent is as follows: 30 parts of papermaking sludge, 15 parts of slag powder, 32 parts of sodium polyacrylate, 36 parts of glycerol, 26 parts of sulfonated oil, 18 parts of activator, 9 parts of oxidant 10 parts, 10 parts of dispersant, 2 parts of p...
Embodiment 2
[0038] On the basis of embodiment 1, in the preparation method of road composite water stabilizer, when spraying soil curing agent, also add solid waste and cement gross weight 7% montmorillonite-quartz powder-silane coupling agent modified polyurethane , wherein, the preparation method of montmorillonite-quartz powder-silane coupling agent modified polyurethane comprises the following steps:
[0039] Step 1, adding dry montmorillonite and quartz powder to polyether glycol, stirring to form a suspension;
[0040] Step 2. Under the protection of nitrogen, add toluene diisocyanate and catalyst to the suspension prepared in step 1, and then gradually raise the temperature to 60° C., and react for 2 hours to obtain a prepolymer;
[0041] Step 3. After cooling the prepolymer prepared in step 2 to 40°C, add small molecule chain extender and silane coupling agent dropwise, and react for 1 hour to obtain montmorillonite-quartz powder-silane coupling agent modified polyurethane ;
