A water-reducing agent for coal-based solid waste concrete and its preparation method are disclosed. The water-reducing agent comprises 40-60 parts of a polycarboxylate-based main agent, 15-25 parts of a slump retainer, 10-20 parts of a crack-resistant reinforcing agent, 5-10 parts of a dispersing agent, 2-5 parts of a stabilizer, and 10-20 parts of deionized water. The slump retainer is a modified polyetheramine prepared by block copolymerization of ethylenediamine with ethylene oxide and propylene oxide; the crack-resistant reinforcing agent is a composite of nano-calcium carbonate and modified lignin sulfonate. This invention reduces the adsorption loss of the water-reducing agent by coal-based solid waste particles through the synergistic effect of the polycarboxylate-based main agent and the modified polyetheramine slump retainer, achieving a slump loss rate of ≤15% after 2 hours.
