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。
