Fireproof cement-based composite material and preparation method thereof
The invention discloses a fireproof cement-based composite material and a preparation method thereof. The preparation method comprises the following steps: 1, adding Portland cement, refined sea sand and water into stirring equipment according to a certain ratio, and automatically stirring at the stirring speed of 250-350r/min for 10-15min to obtain a mixture I after stirring is finished; 2, ceramic fibers, carbon fibers, quartz powder, slag powder, kaolin, synthetic resin and asbestos powder are added into the stirring equipment according to the proportion to be stirred together with the first mixture, the stirring rotating speed is 400-500 r/min, the stirring time is 25-30 min, and a second mixture is obtained after stirring is finished; 3, the second mixture is put into a standard curing chamber to be cured, the curing temperature ranges from 18 DEG C to 22 DEG C, the relative humidity of curing is larger than 90%, the curing time ranges from 30 d to 35 d, and after curing is completed, the finished fireproof cement-based composite material is obtained. The fireproof door has the beneficial effects that the fireproof performance is improved, and the fire safety is enhanced.
本发明公开了一种防火型水泥基复合材料及其制备方法。它包括步骤一，将硅酸盐水泥、精制海沙和水按配比加入到搅拌设备中进行自动搅拌，搅拌转速为250~350r/min，搅拌时间为10~15min，搅拌结束后得到混合物一；步骤二，将陶瓷纤维、碳纤维、石英粉、矿渣粉、高岭土、合成树脂和石棉粉按配比加入到搅拌设备中与混合物一共同搅拌，搅拌转速为400~500r/min，搅拌时间为25~30min，搅拌结束后得到混合物二；步骤三，将混合物二放入到标准养护室中进行养护，养护温度为18~22℃，养护的相对湿度＞90％，养护时间为30~35d，养护结束后得到防火型水泥基复合材料成品。本发明的有益效果是：提高了防火性能，增强了消防安全性。
