Graphite silicon fireproof heat insulation plate and preparation process thereof
The invention discloses a graphite silicon fire-resistant heat-insulating plate and a preparation process thereof, and belongs to the technical field of preparation of air duct fire-resistant heat-insulating plates. The fireproof heat insulation plate is prepared from the following raw materials in parts by mass: 2 to 5 parts of alumina fiber, 0.5 to 1.5 parts of kaolin ground powder, 1 to 3 parts of silicon dioxide particles, 5 to 8 parts of water, 0.1 to 0.3 part of wood fiber, 0.5 to 2 parts of lauryl sodium sulfate, 1 to 2 parts of polycarboxylate and 0.2 to 0.8 part of graphite powder. According to the invention, graphite silicon, which is a high-temperature-resistant, erosion-resistant and good-thermal-conductivity material, is applied to the fireproof heat-insulating plate of the air duct to form a novel fireproof material which is light in weight and high in fireproof temperature, so that the defects that a silicate fireproof plate is heavy in weight and poor in heat-insulating property are overcome; the defects that flexible refractory materials such as rock wool and aluminum silicate wool are low in strength, fibers are prone to falling off and the like are overcome, and the requirement of new smoke regulations for the fire endurance of the smoke prevention and exhaust air pipe can be met.
本发明公开了一种石墨硅耐火隔热板及其制备工艺，属于风管耐火隔热板制备技术领域。该耐火隔热板按质量份数包括以下原料：氧化铝纤维2‑5份，高岭土研磨粉体0.5‑1.5份，二氧化硅颗粒1‑3份，水5‑8份，木纤维0.1‑0.3份，十二烷基硫酸钠0.5‑2份，聚羧酸盐1‑2份，石墨粉0.2‑0.8份，本发明将石墨硅这种耐高温、耐侵蚀、热导性能好的材料应用于风管耐火隔热板上，形成一种轻质、耐火温度高的新型耐火材料，其改善了硅酸盐防火板质量重、隔热性差的缺点，也解决了岩棉、硅酸铝棉等柔性耐火材料强度低、纤维易脱落等弊端，可满足新烟规对于防排烟风管耐火极限的要求。
