Description

一种纳米保温涂料
技术领域
本发明属于保温材料制备技术领域，具体涉及一种纳米保温涂料。 
背景技术
将纳米技术及纳米原料应用于涂料中，可以利用荷叶双蔬原理以及“零对流”等纳米效应，提高涂料的保温隔热性、耐水性和抗霉性能。硅酸铝是一种良好的耐高温、隔热性能好的材料，而纳米硅酸铝由于粒径小、粒径分布窄、没有沉淀分层现象，所以悬浮稳定性好，同时可提高涂料的分散性和细度指标，使得涂料外观、光泽度、硬度和分散性都有良好的效果。在涂料中采用纳米硅酸铝，可使涂料产生“零对流”等纳米效应，极大地降低材料的热传递能力，可作为一种良好的隔热保温材料，弥补传统的墙体保温涂料中存在的吸水性大、易老化、体积收缩大、容易造成产品后期强度低和空鼓开裂降低保温涂料性能等现象，同时又弥补了聚苯颗粒保温涂料易燃，防火性差高温产生有害气体和耐侯低，反弹性大等缺陷。另外，成型稳固、粘结力强、施工方便快，可有效缩短工期，并且不受被保温体几何形状的限制，特别适用于建筑物的内、外墙保温，各种设备，如中央空调下送风系统及异型表面保温，可杜绝传统材料缝隙泄露而损失能量，构成整体密封。 
目前，大部分设备及建筑物保温涂料中起保温作用的主要是泡沫塑料、膨胀珍珠岩和空心微珠等成分，利用颗粒内部的孔隙与颗粒之间的空隙，阻止热流的传递和辐射传热，并取得了一定的保温效果。但是随着国家对设备及建筑物的节能要求，仅靠上述几种材料明显不能满足需求。中国发明专利“一种粉状复合保温涂料”(专利申请号：200810230718.4)主要是以微米级的氧化硅、氧化镁、氧化铝为原料，原料需要粉碎研磨，生产过程较复杂。中国发明专利“复合硅酸盐隔热保温涂料及其生产方法”(专利号：87102864)采用的原料主要是 含水的硅酸镁铝的纤维状材料。也有人加入纳米组分的方法来提高涂料的质量，如专利号为03118030.2的发明专利，就以纯丙乳液为基料，加入纳米级的氧化锌、氧化硅及氧化钛等，虽然具有较好的耐洗刷性能、抗菌自洁功能，但是保温隔热效果较差，生产过程也较复杂。 
发明内容
本发明涉及一种纳米保温涂料。 
一种纳米保温涂料，由如下重量份的组分组成，纳米磷酸铝25-40份、丙烯酸酯类乳液10-15份、纳米氧化锰5-10份、纳米氧化锆2-8份、纳米碳氮化钛3-7份、琥珀酸二辛酯磺酸钠1-5份、十二烷基硫酸钠9-14份、聚乙烯醇21-28份、纳米珍珠岩11-14份、纳米硅酸钙粉4-9份、丙纶纤维5-7份、纳米β-半水石膏粉7-16份、水30-35份。 
制备方法如下： 
在低速搅拌下先原料混合，并在分散机上高速搅拌4-5小时，通过高速剪切将其分散均匀，最后装罐即得涂料成品。 
本发明提高了涂料的保温隔热特性、耐洗刷性及抗菌自洁性等综合性能。本发明符合环保要求的现代工业的发展方向。
