Description
技术领域
本发明涉及材料领域，具体地说，本发明涉及一种外墙环保保温材料。
背景技术
常见的保温隔热材料，无机材料有膨胀珍珠岩、加气混凝土、岩棉、玻璃棉等，有机材料有聚苯乙烯泡沫塑料、聚氨酯泡沫塑料等。这些材料保温隔热效能的优劣，主要由材料热传导性能的高低(其指标为导热系数)所决定。材料的热传导愈难(即导热系数愈小)，其保温隔热性能便愈好。一般地说，保温隔热材料的共同特点是轻质、疏松，呈多孔状或纤维状，以其内部不流动的空气来阻隔热的传导。其中无机材料有不燃、使用温度宽、耐化学腐蚀性较好等特点，有机材料有强度较高、吸水率较低、不透水性较佳等特色。
环保节能保温材料是保温材料未来发展的一个趋势，但是常规的环保节能保温材料其保温性能较差、抗折抗压的强度也较差，并且也不具有较好的耐潮特点，因此在应用中有较多的限制。
发明内容
本发明的目的提供一种外墙环保保温材料，其有效的提高环保保温材料的保温性能，并且提高其抗折强度及耐水强度以及适应性。
本发明采用的技术方案为：一种外墙环保保温材料，包括如下重量份的组分：
酚醛树脂：5～20份；合成树脂乳液：3～12份；
发泡剂：3～8份；表面活性剂：1～2份；膨胀石墨：1～5份；
有机纤维：3～10份；十二烷基二甲基氧化胺：1～3份；
水合氢氧化铝：3～12份；有机硅油：2～5份；
钠基膨润土：3～10份；去离子水：8～20份。
优选的是，所述合成树脂乳液为丙烯酸乳液、苯丙乳液、纯丙乳液、硅丙乳液中的一种或几种。
优选的是，所述酚醛树脂为热固性酚醛发泡树脂胶，树脂固含量为35～86wt％，树脂粘度500～8500mpa.s/25℃。
优选的是，所述表面活性剂是吐温－80、聚二甲基硅氧烷、脂肪醇聚氧乙烯醚、聚乙烯醇、聚乙二醇400、聚乙二醇2000、聚丙烯酰胺、聚环氧乙烷山梨糖醇脂肪酸酯中的一种或多种。
优选的是，所述钠基膨润土的粒度为300～400目，其中蒙脱石的含量≥70％，胶质价≥95mL/5g，Na2O的含量为1.28～2.5％。
优选的是，所述发泡剂是二氧化碳、双氧水、异戊烷、正戊烷、环己烷中的一种。
优选的是，所述有机纤维选自聚酰亚胺纤维、聚苯撑吡啶并二咪唑纤维、聚对苯撑苯并双噁唑纤维和聚对苯并咪唑纤维中的一种或两种以上。
本发明至少包括以下有益效果：
(1)本发明合理筛选配方和各个物料的比份，使得环保保温料的整体性能得到提升，其中添加了合理比份的酚醛树脂，增强了保温材料的抗裂性能，同时选自钠基膨润土，提高保温材料的保温性能的同时也挺了其抗粉化，抗腐蚀性能；
(2)本发明配方合理、简单，综合了集酚醛树脂、合成树脂乳液的优势和特性，辅配水合氢氧化铝、钠基膨润土、膨胀石墨等无机填料，制备的保温材料防火性能好、导热系数低、热稳定性好、抗翘曲、抗腐蚀、抗粉化、防水、防湿、防霉高强度。
