Embodiment 1
[0038] Take respectively: 80% of cement, 16% of 108 glue, 1% of polyacrylamide, 1% of TX-50 emulsifier, 1% of polyester fiber, and 1% of silicon-acrylic emulsion; mix and stir evenly to obtain a gelling enhancer, and set aside; Cut the calcium silicate board to the required size, coat the surface of the calcium silicate board with a gelling enhancer with a thickness of 1mm, and put it into the mold.
[0039] Take respectively: 10% of river sand, 10% of 108 glue, 1% of water reducer, 10% of gypsum, 1% of triethanolamine, 20% of waste rock powder, and the rest of cement, mix and foam to obtain foam cement, and inject foam into the mold. Foaming cement; place it for 48 hours, and after the foamed cement and calcium silicate board are stably combined, remove the mold to obtain a semi-finished lightweight cement board; maintain the semi-finished lightweight cement board for 28 days, and obtain a finished lightweight cement board after curing .

Embodiment 2
[0042] Take respectively: 80% of cement, 10% of 108 glue, 1% of polyacrylamide, 7% of TX-50 emulsifier, 1% of polyester fiber, and 1% of silicone acrylic emulsion; mix and stir evenly to obtain a gelling enhancer, and set aside; Cut the calcium silicate board to the required size, coat the gelling enhancer on the surface of the calcium silicate board, the thickness of the gelling enhancer is 0.1mm, and put it into the mold.
[0043]Take respectively: 5% of river sand, 5% of 108 glue, 1% of water reducer, 5% of gypsum, 1% of triethanolamine, 10% of waste rock powder, and the rest of cement, mix and foam to obtain foam cement, and inject foam into the mold. Foaming cement; place it for 12 hours, after the foamed cement and calcium silicate board are stably combined, remove the mold to obtain a semi-finished lightweight cement board; maintain the semi-finished lightweight cement board for 28 days, and obtain a finished lightweight cement board after curing .
Embodiment 3
[0045] Take respectively: 80% of cement, 5% of 108 glue, 5% of polyacrylamide, 5% of TX-50 emulsifier, 2.5% of polyester fiber, and 2.5% of silicon-acrylic emulsion; mix and stir evenly to obtain a gelling enhancer, and set aside; Cut the calcium silicate board to the required size, coat the gelling enhancer on the surface of the calcium silicate board, the thickness of the gelling enhancer is 1mm, and put it into the mold.
[0046] Take: 1% of river sand, 1% of 108 glue, 0.1% of water reducer, 1% of gypsum, 0.01% of triethanolamine, 2% of waste rock powder, and the rest of cement, mix and foam to obtain foam cement, and inject foam into the mold. Foaming cement; place it for 48 hours, and after the foamed cement and calcium silicate board are stably combined, remove the mold to obtain a semi-finished lightweight cement board; maintain the semi-finished lightweight cement board for 28 days, and obtain a finished lightweight cement board after curing .
