[0017] figure 1 It is a process step diagram of a method for preparing high-reliability cement in the embodiment of the present invention; the high-reliability cement is made of the following raw materials in weight percentage: active magnesium oxide 53-60%, magnesium chloride hexahydrate 10-12%, glass powder 18 ~20%, low-temperature rice husk ash 12-15%; the preparation method of the high-reliability cement includes the following steps: a) preparing glass frit, b) preparing low-temperature rice husk ash, c) preparing slurry by mixing raw materials , D) Hardening and ball milling to make finished products.
[0018] The high-reliability cement mentioned in the present invention uses traditional magnesium oxychloride cement as the main body, and by adding filler glass powder and modifier low-temperature rice husk ash, the strength, wear resistance and water resistance of the cement are significantly improved. Compared with Portland cement, which is currently used more in the const...

[0019] Example 1
[0020] The specific preparation method is as follows:
[0021] a) Prepare glass powder, put the ordinary recycled glass into a special crusher to obtain fine glass powder with a particle size of 0.3~0.5mm and coarse glass powder with a particle size of 1.2~1.4 mm, and then combine the fine glass powder with Coarse glass powder is mixed with a mass ratio of 1.5:1 to prepare glass powder.
[0022] b) To prepare low-temperature rice husk ash, place the ordinary recovered rice husk in a muffle furnace and burn it at 500~600℃ for 40 minutes, then cool the rice husk ash to room temperature, and then grind it with a grinding machine. Pass through a 180-mesh sieve to obtain low-temperature rice husk ash powder.
[0023] c) Mix the raw materials to prepare the slurry. The specific preparation process is as follows: first weigh 60% of active magnesium oxide, 10% of magnesium chloride hexahydrate, 18% of glass powder, and 12% of low-temperature rice husk ash according to weig...
