Novel calcium silicate board for passive fire prevention system
The invention relates to the technical field of calcium silicate board preparation, and discloses a novel calcium silicate fireproof board for a passive fireproof system, which is prepared from the following raw materials in parts by mass: 30 to 50 parts of lime, 20 to 31 parts of diatomite, 31 to 42 parts of quartz powder, 3 to 12 parts of modifier, 3 to 10 parts of reaction aid and 1 to 30 parts of wollastonite fiber, the method comprises the following steps: pre-reaction: reacting silicon dioxide and calcium oxide in a pre-reaction device, heating and pressurizing to generate a tobermorite crystal structure, and mixing 5-50% of the tobermorite crystal structure with raw slurry. By adding the step of pre-reaction, the calcium silicate plate has the excellent characteristics of low high-temperature shrinkage rate, good stability and low high-temperature heat conductivity coefficient, and when the high-temperature shrinkage rate of the calcium silicate plate is low, the size stability of the carbonic acid cover plate in a high-temperature environment can be ensured.
本发明涉及硅酸钙板制备技术领域，公开了一种用于被动防火系统的新型硅酸钙防火板，包括以下质量份数原料：石灰30～50份，硅藻土20～31份，石英粉31～42份，改性剂3～12份，反应助剂3～10份，硅灰石纤维1～30份，所述改性剂为硅酸铝纤维、无机硅树脂的一种或多种组合，所述反应助剂为膨润土或海泡石一种或多种组合，包括以下步骤：预反应、将二氧化硅和氧化钙在预反应装置反应，加热加压生成托勃莫来石晶体结构，取5‑50％和原浆料混合。通过增设了预反映这一步骤，使得硅酸钙板具备高温收缩率较低、稳定性好和高温导热系数低优良特点，硅酸钙板的高温收缩率较低时，可以确保碳酸盖板在高温环境下的尺寸稳定性。
