Embodiment 1
[0040] A novel fire-proof and heat-insulating building material is made of the following raw materials in parts by weight:
[0041]
[0042] It has the advantages of the best fire and heat insulation effect and the lowest cost.
[0043] Slag wool has low bulk density, low thermal conductivity, non-combustibility, heat resistance, frost resistance, corrosion resistance, and strong chemical stability. Using slag wool to make building materials can achieve the purpose of waste reuse.
[0044] A preparation method of a novel fire-proof and heat-insulating building material, comprising the following steps:
[0045] (1) Expanded perlite powder and light calcium carbonate powder are pulverized into 350 mesh powders respectively;
[0046] (2) Take by weight 25 parts of stearyl alcohol, 14 parts of expanded perlite powder, 14 parts of light calcium carbonate powder, 16 parts of mineral wool, 18 parts of glass hollow microspheres, 16 parts of polyurethane foam, rock wool board 65 p...
