Embodiment 1
[0039] Embodiment 1 is shown in Figure 1:
[0040] a. Select 18 kg of nano fly ash with a particle size of 30-35nm, 30 kg of micron fly ash of 100-400 mesh, 15 kg of micron calcium oxide of 100-400 mesh, 15 kg of Portland cement, 1 kg of calcium sulfate, 4 kg of polyacrylate, 5 kg of red pine or white pine wood powder or 2-3 cm long polypropylene fiber;
[0041] b. add the water of 30% of the total weight of materials used in the above steps, i.e. 26.4 kg of water and stir until evenly stirred;
[0042] c. Put the uniformly stirred slurry into the mold or roll it into a plate-shaped blank;
[0043] d. The blank is dried, cured and shaped to form the substrate 1 .
Embodiment 2
[0044] Embodiment 2 is shown in Figure 1:
[0045] a. Select 25 kg of nano fly ash with a particle size of 30-35nm, 20 kg of micron fly ash of 100-400 mesh, 25 kg of micron calcium oxide of 100-400 mesh, 10 kg of Portland cement, 2 kg of calcium sulfate, 6 kg of polyacrylate, 3 kg of red pine or white pine wood powder or 2-3 cm long polypropylene fiber;
[0046] b. Use maleic anhydride and water at a ratio of 1:100 to stir and hydrolyze at high speed to form a coupling agent. Put red pine or white pine wood powder or 2 ~ 3cm long polypropylene fiber into 1 kg of coupling agent, mix well, realize the modification of reinforcing material with coupling agent, to strengthen red pine or white pine wood powder or 2 ~ 3cm Combination of 3cm long polypropylene fibers with other materials such as fly ash;
[0047] c. Add 40% water of the materials used in the above steps, that is, 36.8 kg of water and stir until evenly stirred;
[0048] c. Put the uniformly stirred slurry into the m...
Embodiment 3
[0050] Embodiment 3 is shown in Figure 2:
[0051] a. form the substrate 1 in the manner of embodiment 1 or 2;
[0052] b. Flatten the surface of the substrate, paste decorative cloth or decorative paper or decorative board, etc., to form a decorative layer 2 on the substrate 1;
[0053] c. Mix polyester (No. 191 unsaturated polyester), curing agent (cyclohexanone peroxide) and accelerator (cobalt naphthenate) in a weight ratio of 100:2~5:0.5~3.5 at room temperature , the polyester and curing agent must be fully mixed before adding the accelerator.
[0054] d. Spray or brush the material formed in step c on the decorative layer 2, and at the same time cover the undried flame-retardant and wear-resistant layer 3 with a plastic film until it is dry.
