Water-repellent paper-surface plasterboard and preparation method thereof
The invention provides a water-repellent paper-surface plasterboard. The water-repellent paper-surface plasterboard comprises the following components in parts by weight: 100 parts of desulfurized plaster powder, 2.5-4 parts of emulsified wax, 0.3-1.0 part of starch, 0.03-0.12 parts of a foaming agent and 65-85 parts of water. The paper-surface plasterboard disclosed by the invention has the function of water repelling since emulsified wax is used as the water repellent, can be put in a plaster slurry network structure through paraffin to bloke air pores in plaster, and the function of water repelling is based on the physical action and is not influenced by plaster impurities; as the requirement of the emulsified wax for the purity of plaster is relatively low, the plasterboard disclosed by the invention has better water repellent effect, and when the mixing amount of the emulsified wax is 2.5-3 percent, the water absorption rate of the water-repellent paper-surface plasterboard soaked in water for 2 hours is lower than 10 percent; and when the mixing amount of the emulsified wax is 3.5-4 percent, the water absorption rate of the water-repellent paper-surface plasterboard soaked in water for 2 hours is lower than 5 percent.
