Fire-resistant thermal-insulation inorganic plate and preparation method thereof
The invention provides a fire-resistant heat-preservation inorganic plate. The fire-resistant heat-preservation inorganic plate is prepared from materials including inorganic fire-resistant fibers, clay minerals and an inorganic binding agent. In the preparation process of the fireproof thermal insulation inorganic plate, a starch organic binder is removed, and clay minerals with specific specificsurface area and granularity are used as an adsorbent, so that the problem of insufficient flocculation of an inorganic binder and fibers is solved. Herein, the fire-resistant heat-insulating inorganic plate is directly prepared through one-step drying without a high-temperature calcining process, wherein the fire-resistant heat-insulating inorganic plate is smokeless and tasteless when used in ahigh-temperature environment, and meanwhile, the compressive strength and the breaking strength are improved compared with those in a normal-temperature state; the fireproof heat preservation inorganic plate has excellent heat insulation performance and mechanical performance and can be applied to large industrial kilns or other high-temperature load-bearing heat insulation and heat preservationfields in the petrochemical industry, the metallurgy industry, the electric power industry and the like.
本发明提供了一种耐火保温无机板，由包括无机耐火纤维、粘土类矿物质和无机结合剂的物料制备得到。本发明提供的耐火保温无机板在制备过程中去除了淀粉类有机粘结剂，采用具有特定比表面积、粒度的粘土类矿物质作为吸附剂，解决了无机结合剂与纤维絮凝不充分的难题，通过一步烘干直接制备出耐火保温无机板而不需要再经过高温煅烧工艺；耐火保温无机板在高温环境下使用无烟无味，同时抗压强度、抗折强度比常温状态下均有提升；耐火保温无机板具有优良的绝热性能和力学性能，可应用于石化、冶金、电力等行业大型工业窑炉或其他高温承重绝热保温领域。
