The invention relates to a multifunctional water reducing agent as well as a preparation method and application thereof. The multifunctional water reducing agent is prepared by mixing the following raw materials in parts by weight: 70%-80% of naphthalene sulfonate formaldehyde condensate, 10%-20% of lignin, 1%-5% of starch ether, 2%-5% of sodium carbonate and 2%-5% of sodium hydrogen sulfite. The multifunctional water reducing agent is applied to concrete, has good adaptability to cement and strong dispersing capacity, can obviously improve and enhance the workability of the concrete and reduce slump loss, and has the advantages of low mixing amount, high water reducing rate, obvious enhancing effect and the like. When the multifunctional water reducer is applied to soil solidification, the strength and toughness of solidified soil can be improved, and the solidified soil exposed under the sun for a long time is stable, firm and free of cracking. When the multifunctional water reducing agent is applied to coal water slurry, the hydrophilicity of the coal surface can be improved, the surface tension of coal water can be reduced, coal particles can be fully wetted and uniformly dispersed in a small amount of water, the fluidity of the coal water slurry can be improved, the viscosity of the coal water slurry can be reduced, and the slurry has good rheological property and stability.
本发明涉及一种多功能减水剂及其制备方法与应用。所述多功能减水剂由以下重量份的原料混合而成：萘磺酸盐甲醛缩合物70％‑80％，木质素10％‑20％，淀粉醚1％‑5％，碳酸钠2％‑5％，亚硫酸氢钠2％‑5％。所述多功能减水剂应用于混凝土中对水泥的适应性好，分散能力强，能显著改善和提高混凝土的和易性，减小坍损，具有掺量低，减水率高，增强效果显著等优点。所述多功能减水剂应用于泥土固化中能增加固化土的强度和韧性，使得长期暴晒的固化土稳定坚实不开裂。所述多功能减水剂应用于水煤浆中能改善煤表面亲水性，降低煤水表面张力，使煤粒充分润湿和均匀分散在少量水中，改善水煤浆流动性，降低水煤浆粘度，使浆体有良好的流变特性和稳定性。
