preparation example Construction

[0053] The preparation method of the clay material that can be used for 3D printing, comprises the following steps:

[0054] S1: Take the soil with a pH of 8-11.5, air-dry it naturally, put it into a planetary ball mill to grind, pass the soil powder through a 350-400 mesh sieve, and obtain the clay material of the raw material;

[0055] S2: crushing the stone through a 250-300 mesh sieve to obtain calcium carbonate powder;

[0056] S3: Treat plants, fallen leaves, and residues at 1100-1300°C to make plant ash;

[0057]S4: Mix 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 low-temperature pulverizer, and pulverize the mixture at a temperature of -100-108°C for 2- 3h, obtain 80-100 mesh material A after sieving;

[0058] S5: Add a specific synthetic agent to the material A prepared in step S4, raise the temperature to 152-160° C., knead at a rotation speed of 60-80 r / min for 4-5 hours, and ...
