Manufacturing method of fireproof calcium silicate board
The invention discloses a manufacturing method of a fireproof calcium silicate board. The manufacturing method comprises the following steps: S1, accurately weighing calcium silicate board mineral rawmaterials, drying and uniformly mixing; S2, pulping the wood fibers and the rock wool fibers to form raw material pulp; S3, adding the solid raw material powder and water into a high-pressure kettlewith a stirrer, and performing hydrothermal treatment to obtain active slurry; S4, mixing and stirring the active slurry raw material slurry, and carrying out filter pressing molding after uniform stirring to prepare a calcium silicate board wet blank; and S5, carrying out pre-curing and steam curing on the wet blank of the calcium silicate board at normal temperature and normal pressure to obtainthe calcium silicate board. Industrial wastes including fly ash, silica fume and carbide slag are used as cementing materials, wood fibers and rock wool fibers are used as reinforcing fibers, and theprocess is improved, so that the prepared calcium silicate board has relatively high impact resistance and flame retardance.
本发明公开一种防火用硅酸钙板制作方法，包括以下步骤：S1：准确称取硅酸钙板矿物原料烘干、混合均匀；S2：将木纤维、岩棉纤维进行打浆处理形成原料浆液；S3：将固体原料粉和水加入带搅拌器的高压釜中水热处理得到活性浆料；S4：活性浆料原料浆液混合搅拌，搅拌均匀后压滤成型，制得硅酸钙板湿坯；S5：将硅酸钙板湿坯进行温常压下预养养护和蒸汽养护，得到硅酸钙板。本发明采用工业废料粉煤灰、硅灰和电石渣为胶凝材料，以木纤维和岩棉纤维为增强纤维，并通过对工艺的改进，使制得的硅酸钙板具有较高的抗冲击性能和阻燃性能。
