Embodiment 1
[0033] The preparation of an EPS light aggregate thermal insulation and decoration integrated board, in parts by weight, comprises the following steps:
[0034] 1) Stir and mix 30 parts of EPS foam particles, 40 parts of iron tailings sand, 200 parts of ordinary portland cement, 10 parts of rubber powder, 10 parts of hydroxymethyl cellulose and 250 parts of water to obtain a mixed slurry;
[0035] 2) Transfer the mixed slurry obtained in step 1) to a mold, and dry it naturally for 3 days, so that the water in the mixed slurry evaporates and the mixed slurry forms a solid in the mold. core;
[0036] 3) Mix 20 parts of iron tailings sand, 65 parts of ordinary portland cement, 2 parts of rubber powder, 2 parts of hydroxymethyl cellulose and 120 parts of water to obtain a bonding mortar;
[0037] 4) Cut the fiber mesh cloth according to the size of the thermal insulation core to the corresponding area size. Step 2) After attaching a layer of fiber mesh cloth to the outer surface ...
Embodiment 2
[0041] The preparation of an EPS light aggregate thermal insulation and decoration integrated board, in parts by weight, comprises the following steps:
[0042] 1) Stir and mix 50 parts of EPS foam particles, 80 parts of iron tailings sand, 300 parts of ordinary portland cement, 20 parts of rubber powder, 20 parts of hydroxymethyl cellulose and 300 parts of water to obtain a mixed slurry;
[0043] 2) Transfer the mixed slurry obtained in step 1) to a mold, and let it dry naturally for 7 days, so that the water in the mixed slurry evaporates and the mixed slurry forms a solid in the mold, and the mold is demoulded to obtain a solid plate-shaped insulation inner core;
[0044] 3) Mix 30 parts of iron tailings sand, 75 parts of ordinary Portland cement, 3 parts of rubber powder, 3 parts of hydroxymethyl cellulose and 150 parts of water to obtain a bonding mortar;
[0045]4) Cut the fiber mesh cloth according to the size of the thermal insulation core to the corresponding area si...
