Embodiment 1
[0023] Get the magnesium hydroxide that is 10% by weight, the magnesium sulfate of 25%, the calcium carbonate of 10%, the lignin of 15%, the calcium sulfonate of 10% and the deionized water of 30% are made into mixed solution stand-by; Take Immerse the volcanic rock in the mixed solution at room temperature for 10-20 minutes, the volume ratio of the volcanic rock to the mixed solution is 2:5; heat the solution, and heat it at a constant temperature after the temperature rises to 70-80°C, control the heating time for 2-4 hours, and then cool to room temperature; heat the solution a second time, and heat it at a constant temperature after the temperature rises to 50~55°C, control the heating time for 6~8h, and then cool to room temperature; separate the obtained volcanic rock from the solution, let it stand to dry, Bake at 150°C for 5-6 hours, then cool to room temperature.
