Method for preparing light partition wall board by utilizing desulfurized gypsum
The invention discloses a method for preparing a light partition wall board by utilizing desulfurized gypsum. The method comprises the following steps: in percentage by weight, weighing 40-60 percent of the desulfurized gypsum and 60-40 percent of the desulfurized gypsum; mixing the desulfurized gypsum to obtain a mixture serving as a base material; adding 2-5 percent of quick lime, 10-15 percent of cement, 0.6-0.8 percent of a naphthalene water reducer, 2-3 percent of a triggering agent, 0-0.03 percent of an air entraining agent and 0.3-0.5 percent of a reinforcing fiber into the base material based on the total mass of the base material; uniformly mixing; adding water of which the mass is 65% of the total mass of the mixed materials into the mixture; stirring and simultaneously adding 80% of polystyrene foam particles based on the total volume; uniformly mixing to obtain a thick pasty wet material containing foam particles; filling the wet material into a mold; and demolding and maintaining to form the light partition wall board. By adopting the desulfurized gypsum as a cementing material, a great amount of solid wastes such as the desulfurized gypsum are consumed, and the product is good in water resistance, low in investment and low in cost.
