Embodiment 1
[0018] The first step: prepare raw materials according to raw material ratio, by weight,
[0019] Magnesia-calcium sand: 20 parts of granules with a diameter of 3-5mm, 20 parts of granules with a diameter of 1-3mm, and 20 parts of granules with a diameter of 0-1mm, a total of 60 parts, mixed evenly after drying;
[0020] Magnesia: 30 parts of fine material with diameter less than or equal to 0.088mm;
[0021] Silica: 1 part of granular material with a diameter less than or equal to 45 microns;
[0022] Solid resin: 1 part of solid phenolic resin;
[0023] Dry clay: Dry the soft clay for 24 hours at a temperature not lower than 110°C, then take 2 parts
[0024] Bentonite: 2 parts of bentonite;
[0025] Tung oil: 5 parts of tung oil.
[0026] The second step is to manually mix the magnesia-calcium sand, magnesia, silicon dioxide, and solid resin according to the proportion;
[0027] The third step is to add dry clay and bentonite, and mix evenly by hand;
[0028] The fourt...
Embodiment 2
[0030] Make according to Example 1, and add the following steps
[0031] Step 5: Add soda ash to adjust the pH to 11-12 in an environment of 60 degrees Celsius, and stir for 5-10 minutes before cooling to room temperature. Prepare uniformly mixed materials, adjust the pH value, and stir at 60 degrees Celsius for 5-10 minutes and then cool to room temperature to improve the moisture retention and hydration resistance of the materials.
