The invention discloses a formula of a special fireproof plate for a ventilation pipe. Raw materials of the special fireproof plate comprise the following components: building gypsum powder, a high-performance additive and inorganic mineral lightweight aggregate, the high-performance admixture comprises a gypsum retarder, a water reducing agent and an air entraining agent; the inorganic mineral lightweight aggregate is glass bead particles. The building gypsum powder is used as a main material. The building gypsum powder is also called semi-hydrated gypsum and is a light, high-strength and fast-setting cementing material, and the molecular structure of the building gypsum powder contains half free water which cannot be volatilized, so that the building gypsum powder has good fire resistance. According to the invention, glass bead particles are used as a filling material. The vitrified microbead particles have the characteristics of hydrophilicity, high strength and low heat conductivity coefficient, and are filled in the gypsum, so that the density of the gypsum can be reduced, and the heat insulation performance and the frost resistance can be improved; and the requirement of poor loading capacity of the ventilation pipeline can be met. The high-strength cement has good strength, and the physical property of the high-strength cement is not lower than that of magnesium cement. And the fire resistance meets the requirements of national standards.
本发明公开了一种通风管专用防火板配方,原料包括如下成分:建筑石膏粉,高性能外加剂和无机矿物轻集料;高性能外加剂包括:石膏缓凝剂,减水剂和引气剂;无机矿物轻集料为玻化微珠颗粒。本发明采用建筑石膏粉作为主料。建筑石膏粉也称为半水石膏,是一种轻质、高强、快凝的胶凝材料,其分子结构中含有半个游离水不会挥发,因此具有良好的耐火性能。本发明采用玻化微珠颗粒作为填充料。玻化微珠颗粒具有亲水性、高强度和低导热系数的特点,填充在石膏内,可以减少石膏的密度,提高隔热性能和抗冻性能;使其在可以满足通风管道载重能力较差。本发明的具有良好的强度,其物理性能不低于镁质水泥。且耐火性符合国家标准的要求。
