Insulation board for building curtain wall, and preparation process thereof
The invention discloses an insulation board for a building curtain wall, and a preparation process thereof. The insulation board is prepared from, by weight, 30-40 parts of silica fume, 15-30 parts offly ash, 2.5-5 parts of azodicarbonamide, 60-80 parts of deionized water, 20-40 parts of polystyrene, 7.5-10 parts of a flame retardant, 7-15 parts of a light stabilizer, 100-150 parts of cement, 15-20 parts of a modifying reinforcing agent and 1.5-3 parts of an early strength agent. The modifying reinforcing agent contains an alkoxy group, and the alkoxy group is connected to a silicon atom, anda condensation reaction is carried out on the alkoxy group and an active hydroxyl group on the surface of the silica fume to form a Si-O-Si bond, so the hardness of the insulation board is further improved; and molecules of the modifying reinforcing agent contain a large number of halogen groups, the viscosity of the foaming particles is increased due to a large number of hydrogen bonds, and theVan der Waals attraction and the winding degree between macromolecular chains of the foaming particles are correspondingly increased, so the toughness of the insulation board is improved, the insulation board is not prone to cracking, and the service life of the insulation board is further prolonged.
本发明公开了一种用于建筑幕墙的保温板及其制备工艺，该保温板由如下重量份原料制成：硅灰30‑40份、粉煤灰15‑30份、偶氮甲酰胺2.5‑5份、去离子水60‑80份、聚苯乙烯20‑40份、阻燃剂7.5‑10份、光稳定剂7‑15份、水泥100‑150份、改性增强剂15‑20份、早强剂1.5‑3份；该改性增强剂种含有烷氧基且烷氧基连接在硅原子上，与硅灰表面的活性羟基发生缩合反应形成Si‑O‑Si键，进而增加保温板的硬度,且改性增强剂分子中含有大量的卤素基团，阻碍水分向保温板内部渗透，同时大量氢键使得发泡颗粒的粘度增大，发泡颗粒大分子链间范德华引力和缠绕程度相应增加，进而增加保温板的韧性，不易发生开裂，进一步增长了保温板的使用寿命。
