Thermal-insulation fireproof composite material for building and preparation method of thermal-insulation fireproof composite material
The invention relates to a thermal-insulation fireproof composite material for buildings and a preparation method thereof, and belongs to the technical field of thermal-insulation material preparation, and the preparation method comprises the following steps: using 1, 3, 5-triformyl phloroglucinol and p-phenylenediamine to modify 9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide to obtain a modified flame retardant; adding a modified flame retardant into a polyurethane material to prepare a fireproof layer; carrying out hydrophobic treatment on silk fibroin fibers, and then mixing the silk fibroin fibers with dopamine-modified carboxylated expanded graphite to prepare fiber-based gel; the surface of a fireproof layer is coated with fiber-based gel, then a layer of oxidizing solution is sprayed, then the fiber-based gel is clamped between the fireproof layer, pressure is applied, fixing is conducted, then the material is freeze-dried, a fireproof layer-gel layer-fireproof layer structure is formed, and the heat-preservation fireproof composite material for the building is obtained. The prepared thermal-insulation fireproof material has the characteristics of good mechanical property and low heat conductivity coefficient.
本发明涉及一种建筑用保温防火复合材料及其制备方法，属于保温材料制备技术领域，包括以下步骤：使用1，3，5‑三甲酰基间苯三酚和对苯二胺对9，10‑二氢‑9‑氧杂‑10‑磷杂菲‑10‑氧化物进行改性，得到改性阻燃剂；在聚氨酯材料中添加改性阻燃剂，制备防火层；对丝素蛋白纤维进行疏水处理，随后与多巴胺改性的羧化膨胀石墨混合，制备纤维基凝胶；将纤维基凝胶覆涂在防火层表面，随后喷涂一层氧化性溶液，再使用防火层将纤维基凝胶夹在中间，施加压力，固定，随后将材料冷冻干燥，形成防火层‑凝胶层‑防火层结构，即得一种建筑用保温防火复合材料。所制得的保温防火材料具有机械性能好，导热系数低的特点。
