Fireproof door core board and production process thereof
The invention provides a fireproof door core board, and belongs to the technical field of fireproof doors. The fireproof door core board is prepared from the following raw materials of, in parts by weight, 80 parts-280 parts of cement, 0.2 part-8 parts of a foaming agent, 0.1 part-1 part of polypropylene fibers, 0 part-200 parts of an admixture, 140 parts-160 parts of water and 0 part-1 part of an early strength water reducing agent. The fireproof performance of the fireproof door core board reaches the standard, the environmental protection performance reaches the standard, the dry density value is not higher than 300 kg/m < 3 >, the tensile strength is not lower than 0.13 MPa, the drying shrinkage value is not higher than 0.5 mm/m, the water absorption rate (V/V) is 3%-5%, the carbonization coefficient and the softening coefficient are not lower than 0.9, and the fireproof door core board shows excellent use durability.
本发明提供了一种防火门芯板，属于防火门技术领域。一种防火门芯板，由如下重量份的原料制成：水泥80‑280份，发泡剂0.2‑8份，聚丙烯纤维0.1‑1份，掺合料0‑200份，水140‑160份，早强减水剂0‑1份。本发明防火门芯板的防火性能达标，环保性能达标，干密度值不高于300kg/m3，抗拉强度不低于0.13MPa，干燥收缩值不高于0.5mm/m，吸水率（V/V）为3‑5%，碳化系数和软化系数均不低于0.9，表现出优异的使用耐久性。
