Refractory material and preparation method thereof
The invention discloses a refractory material and a preparation method thereof. The preparation method comprises the steps: with filler and cement as base materials, adding the filler and the cement into a concrete mixer according to the proportional relation for dry material stirring, adding water for slurrying after the stirring time is 2-3 min, controlling the water cement ratio to be 0.5-0.6,and fully stirring the mixture to make slurry; then adding reinforcing fibers and silica sol into slurry, carrying out secondary stirring, carrying out modification treatment on polystyrene foam particles and polyphenyl particles, adding modified particles, continuing stirring to obtain a precursor, and adding a foaming agent and a water reducing agent to form foams to obtain the refractory material. The refractory material can be used as a filler. The energy-saving and heat-preservation effects are good, the combustion performance reaches the non-combustible grade A, and the cost is low.
本发明公开了一种耐火材料及其制备方法，其利用填料和水泥作为基材，将将填料、水泥按照比例关系加入混凝土搅拌机中进行干料搅拌，搅拌时间为2~3min后加水制浆，控制水灰比为0.5~0.6，进行充分搅拌后得到浆料，浆料中加入增强纤维以及二氧化硅溶胶后二次搅拌，然后对聚苯乙烯泡沫颗粒和聚苯颗粒进行改性处理，将改性后的颗粒物加入后继续搅拌得到前驱体，然后加入发泡剂以及减水剂，生成泡沫后得到耐火材料。该耐火材料可作为填充料进行使用。本发明节能保温效果较好，燃烧性能达不燃A级，成本较低。
