Description
技术领域
本发明涉及建筑材料技术领域，尤其涉及一种菱苦土复合外墙保温板及其制造方法。
背景技术
建筑物隔热保温是节约能源、改善居住环境和使用功能的一个重要方面，目前外墙外保温技术是建筑围护结构节能的必要和关键措施，从国内外发展来看，对外墙外保温防火安全性的要求应作为该技术应用的首选条件。目前的保温板尚难以满足耐高温，耐低温，耐腐蚀，耐磨，隔音、隔热、阻燃，防水，防火、绝热，强度高，抗冲击，抗撞击、抗震、不龟裂，比重轻，粘接抗裂性能好，耐候性强，强度大、寿命长、节能、用途适用范围广等综合性能理想的要求。
发明内容
本发明的目的是克服现有技术的不足，提供一种菱苦土复合外墙保温板，具有体轻、多孔、隔声、耐热、耐酸及化学性质稳定等一系列优良特性，耐火等级达到A级要求，耐火性能好，无安全隐患，耐候性、耐久性强，具有良好的吸声效果，能有效降噪。
为了实现上述目的，本发明采用如下技术方案：
一种菱苦土复合外墙保温板，由以下重量份原料制成：菱苦土20-25份、冰晶石粉3-6份、锆英粉1-3份、鸡蛋壳粉3-6份、锰渣颗粒2.5-3.5份、硅酸钠0.5-0.8份、硬脂酸镁0.8-1.9份、聚苯颗粒6-10份、水15-30份、发泡剂0.3-0.8份、憎水剂0.5-1份、菠萝麻纤维浆料5-7份、复合助剂1-7份；
所述复合助剂由以下方法制备：按重量份计，取壳聚糖5-7份、高岭土3-6份、二氧化硅2-4份、氢氧化钠2-4份、氯化铵1-3份、椰油酰二乙醇胺0.5-1份、可再分散乳胶粉5-7份、丙烯酸羟乙酯0.3-0.5份，将壳聚糖溶解于适量4％的醋酸水溶液，加入高岭土、二氧化硅研磨30min，将pH调至中性后依次加入氢氧化钠、氯化铵，60℃搅拌30min，将pH调至中性，常温下加入其余原料，搅拌30min后喷雾干燥，即得。
所述的菱苦土复合外墙保温板的制造方法，包括以下步骤：
(1)按重量份将菱苦土、冰晶石粉、锆英粉、鸡蛋壳粉、锰渣颗粒充分搅拌混合，然后加入硅酸钠、硬脂酸镁、水、憎水剂、菠萝麻纤维浆料充分搅拌混合得混合料；
(2)将聚苯颗粒和发泡剂喂入蒸汽压0.2-0.4MPa、预热到75-85℃的预发机内进行预发泡，经过8-9h熟化得到预发泡的聚苯颗粒；
(3)模压成型：将预发泡的聚苯颗粒、步骤(1)的混合料、复合助剂混合均匀，使用流化床干燥设备干燥，然后放入预热的板材成型机中，模内导入100-110℃蒸汽加热，保持压力为0.08-0.15MPa，待通气结束后冷却、脱模得生坯；
(4)固化：将生坯进行热处理，固化温度为200-220℃，固化时间6-8小时，然后定尺切割。
锰渣是一种蜂窝状多孔结构的工业废渣，它是锰铁合金和硅锰合金冶炼过程中高温炉渣经水淬冷却而成，具有质轻、多孔，孔结构表明锰渣理论上具有较低导热系数，利用锰渣颗粒，提高保温板的内部结构，保证保温性能和改善强度。
与已有技术相比，本发明的有益效果如下：
本发明的菱苦土复合外墙保温板，具有体轻、多孔、隔声、耐热、耐酸及化学性质稳定等一系列优良特性，耐火等级达到A级要求，耐火性能好，无安全隐患，耐候性、耐久性强，具有良好的吸声效果，能有效降噪。

所述复合助剂由以下方法制备：按重量份计，取壳聚糖5-7份、高岭土3-6份、二氧化硅2-4份、氢氧化钠2-4份、氯化铵1-3份、椰油酰二乙醇胺0.5-1份、可再分散乳胶粉5-7份、丙烯酸羟乙酯0.3-0.5份，将壳聚糖溶解于适量4％的醋酸水溶液，加入高岭土、二氧化硅研磨30min，将pH调至中性后依次加入氢氧化钠、氯化铵，60℃搅拌30min，将pH调至中性，常温下加入其余原料，搅拌30min后喷雾干燥，即得。
2.根据权利要求1所述的菱苦土复合外墙保温板的制造方法，其特征在于：包括以下步骤：
(1)按重量份将菱苦土、冰晶石粉、锆英粉、鸡蛋壳粉、锰渣颗粒充分搅拌混合，然后加入硅酸钠、硬脂酸镁、水、憎水剂、菠萝麻纤维浆料充分搅拌混合得混合料；
(2)将聚苯颗粒和发泡剂喂入蒸汽压0.2-0.4MPa、预热到75-85℃的预发机内进行预发泡，经过8-9h熟化得到预发泡的聚苯颗粒；
(3)模压成型：将预发泡的聚苯颗粒、步骤(1)的混合料、复合助剂混合均匀，使用流化床干燥设备干燥，然后放入预热的板材成型机中，模内导入100-110℃蒸汽加热，保持压力为0.08-0.15MPa，待通气结束后冷却、脱模得生坯；
(4)固化：将生坯进行热处理，固化温度为200-220℃，固化时间6-8小时，然后定尺切割。
