preparation example Construction

[0063] The preparation method of described 3D printing clay material comprises the following steps:

[0064] S1: Take the soil with pH ≥ 7, air-dry it naturally, put it into a planetary ball mill to grind, pass the soil powder through a 200-400 mesh sieve, and obtain the clay material of the raw material;

[0065] S2: crushing the stone through a 100-300 mesh sieve to obtain calcium carbonate powder;

[0066] S3: Treat plants, fallen leaves, and residues at 1000-1400°C to make plant ash;

[0067] S4: Put the clay material prepared in step S1, the calcium carbonate powder prepared in step S2, and the plant ash prepared in step S3 into a pulverizer after mixing, pulverize the mixture at room temperature for 10-20min, and sieve to obtain 80- 90 mesh material A;

[0068] S5: Add a specific synthetic agent to the material A prepared in step S4, raise the temperature to 140-160° C., knead at a rotation speed of 40-60 r / min for 3-5 hours, and then cool to room temperature to obtain...
