Preparation method of inorganic lightweight aggregate insulation board
The invention discloses a preparation method of an inorganic lightweight aggregate insulation board. The preparation method comprises the following steps: preparing Portland cement powder, uniformly mixing the Portland cement powder with cellulose and inorganic reinforced fibers to form a powdery mixed material; uniformly mixing water and a water reducing agent to form a liquid mixed material; mixing the powdery mixed material with the liquid mixed material, adding an early strength agent, an anti-freezing agent and a water repellent to obtain viscous composite slurry; mixing expanded perliteand the composite slurry under stirring until the surface of the expanded perlite is uniformly coated with a layer of composite slurry to obtain a light pre-pressed material; pressurizing a lower template and an upper template, compressing to form a plate blank; shaping the plate blank; and carrying out steam-curing in curing equipment to obtain the insulation board. The surface area of the composite slurry coating on the surface of the expanded perlite is increased, the lattice defect roughness is improved, and the self-healing capability is enhanced.
本发明公开一种无机轻集料保温板的制备方法，包括以下步骤：制备硅酸盐水泥粉料，并将硅酸盐水泥粉料和纤维素、无机增强纤维混合均匀形成粉状混合物料；将水和减水剂混合均匀形成液体混合物料；将粉状混合物料和液体混合物料混合，并添加早强剂、抗冻剂以及憎水剂，得到粘稠状复合浆体；将膨胀珍珠岩与复合浆体搅拌混合，直至膨胀珍珠岩表面均匀包裹一层复合浆体材料，得到轻质预压料；下模板和上模板进行加压，压缩形成板坯；使板坯定型；在养护设备中蒸汽养护，最后制成保温板成品；本发明使在膨胀珍珠岩表面的复合浆料涂层表面积增大、晶格缺陷粗糙度提高、自愈性能力增强。
