Example Embodiment
[0030] The preparation method of the environmental protection brick includes the following steps:
[0031] S1: Preparation of hollow brick
[0032] Mix cement, shale ore, fly ash, tailings sand, and kaolin, and mix them evenly at a speed of 200-400r / min to make hollow bricks;
[0033] S2: Preparation of new foam materials
[0034] S21: Stir the cement, glyoxal and water at a speed of 100-300r / min to make slurry;
[0035] S22: Combine calcium silicate, calcium sulfate, bentonite, magnesium borate, corn stalk powder, AR glass fiber, carbon fiber, water reducing agent, foaming agent, foaming regulator, catalyst, cross-linking agent and foam stabilizer in Stir at 60-100r / min for 2-3h to prepare foam liquid;
[0036] S23: Add the foam liquid prepared in step S22 to the slurry prepared in step S21, and stir uniformly at a speed of 150-200 r / min to prepare a new foaming material;
[0037] S3: Preparation of insulation bricks
[0038] The new foam material prepared in step S2 is filled into the c...
