Abstract
本发明公开了一种降噪耐磨抗老化外墙涂料及其制造方法，该降噪耐磨抗老化外墙涂料以含根管藻孢子浓度1×106cfu/ml-1×108cfu/ml的海水、蒙脱石、高岭土、饱和浓硫酸、草酸、丙三醇、硫酸镍、泡花碱水溶液、铝粉和足量水为原料，经过处理获得的两层结构；其中，底层为通过明火炙烤及电热脉冲将蒙脱石、高岭土、铝粉混合土料陶化并通过铝表面硬质氧化加强，获得混合网格状炭化纤维及硅酸凝胶胶结结构的陶质结构基底；表层为通过硅酸凝胶固结粘连的疏孔的蒙脱石、高岭土混合土料，同时该土料中还夹杂有大量表面硬质阳极氧化的铝芯颗粒。本发明降噪效果好、表面耐磨、耐紫外线、不易开裂脱落。
Description
本发明涉及隔音涂料技术领域，尤其涉及一种降噪耐磨抗老化外墙涂料的制造方法。
现有技术中，高端的隔音涂料里的主要隔音原料为纳米多层结构材料，将涂料分子材料夹在中间。整个中间膜均匀地分布了具有隔音效果的微粒子，通过减少透射的声波能量，从而起到吸音隔音的作用。
隔音涂料里同时还有部分吸音纳米材料，吸音纳米材料表面充满了直径为 1um左右的小孔，小孔由表面向中心深入，孔的容积占颗粒面积50%左右，因此具有良好的吸附性能，且对目的物有缓释作用。
但现有技术中的隔音涂料有几个很大的缺陷：一是原料成本高，施工设备和施工技术要求高，实施成本大、质量不稳定；二是这种涂层由于采用多层层叠结构，墙面结合力一般，较易开裂和脱落；三是这种涂层表面凹凸不平，且由于涂料本身强度低，不耐磨，易受外力损毁；四是吸音系数较低，只能通过加厚涂层厚度弥补（一般5mm左右），导致墙面结合力差；五是涂料本身日常使用中不耐酸雨、不耐紫外线，使用受限。
因此，市面上急需一种降噪效果好、表面耐磨、耐紫外线、不易开裂脱落的降噪耐磨抗老化外墙涂料制造方法。
发明内容本发明旨在提供一种降噪效果好、表面耐磨、耐紫外线、不易开裂脱落的降噪耐磨抗老化外墙涂料制造方法。
为了实现上述目的，本发明采用以下技术方案：一种降噪耐磨抗老化外墙涂料，该降噪耐磨抗老化外墙涂料以按重量份计的含根管藻孢子浓度1×106cfu/ml-1×108cfu/ml的足量海水、蒙脱石30-35份、高岭土80份-100份、足量饱和浓硫酸、足量草酸、足量丙三醇、足量硫酸镍、20%质量浓度的泡花碱水溶液65份-70份、粒径10μm-50μm的铝粉15份-18份和足量水为原料，经过处理获得的两层结构；其中，底层为通过明火炙烤及电热脉冲将蒙脱石、高岭土、铝粉按质量比（3-3.5）：（8-10）：（1.5-1.8）配比的混合土料陶化并通过铝表面硬质氧化加强，混合根管藻炭化后形成的网格状炭化纤维及硅酸凝胶胶结结构获得的疏孔陶质结构基底；表层为通过硅酸凝胶固结粘连的疏孔的蒙脱石、高岭土按质量比（3-3.5）：（8-10）的混合土料，同时该土料中还夹杂有表面硬质阳极氧化的铝芯颗粒。
一种降噪耐磨抗老化外墙涂料的制造方法，包括以下步骤；
1）原料准备
①原材料准备：按重量份准备含根管藻孢子浓度1×106cfu/ml-1×108cfu/ml的足量海水、蒙脱石30-35份、高岭土80份-100份、足量饱和浓硫酸、足量草酸、足量丙三醇、足量硫酸镍、20%质量浓度的泡花碱水溶液65份-70份、粒径10μm-50μm的铝粉15份-18份；
②辅料准备：准备足量水；
2）底层涂覆
①将阶段1）步骤①准备的蒙脱石、高岭土、铝粉混合均匀，并添加40份-45份的泡花碱水溶液，室温下搅拌均匀，获得湿热粘土；
②将步骤①获得的湿热粘土按质量比7：3分离，选取其中占比30%的部分均匀涂覆在外墙墙面上，涂覆厚度0.5mm-1mm，获得底层涂料；
③静置底层涂料1-2天至涂料固结，出现疏孔和裂纹，然后在涂料表面均匀喷涂阶段1）步骤①准备的含根管藻孢子浓度1×106cfu/ml-1×108cfu/ml的海水，至底层涂料含水量升至30%-40%，然后持续喷水保持湿度至底层涂料及裂纹中的墙体表面完全覆盖生长出致密褐色苔，获得待处理底层涂料；
④采用明火烘烤待处理底层涂料至涂料再次干结、褐色苔炭化，即获得所需底层涂料；
3）表层涂覆
①将阶段1）步骤①准备的饱和浓硫酸、草酸、丙三醇、硫酸镍与阶段1）步骤②准备的水混合并调配成硫酸质量浓度240g/L-260g/L、草酸质量浓度12g/L-13g/L、丙三醇体积浓度6ml/L-6.5ml/L、硫酸镍质量浓度12g/L-13g/L的混合水溶液；
②将阶段2）步骤②获得的剩余70%湿热粘土再混合并搅拌均匀，然后均匀拍打涂覆于阶段2）获得的底层涂料表面，获得待处理涂覆层；
4）涂料成型
①将380V三相动力电源的三相电极分别施加在阶段3）获得的待处理涂覆层对应墙面的顶部两角和底部中间位置，然后将阶段3）步骤①获得的混合水溶液持续、均匀地喷淋在待处理涂覆层表面，使待处理涂覆层含水量保持60%-65%，保持2h-3h，停止喷淋阶段3）步骤①获得的混合水溶液，获得初处理涂层；
②保持通电，将剩余的泡花碱水溶液均匀喷涂在步骤①获得的初处理涂层表面，喷涂完后立即停止通电，自然干燥后，即获得所需降噪耐磨抗老化外墙涂料。
与现有技术相比较，本发明具有以下优点：（1）本发明的所有成份分别是陶质结构、炭化结构和胶硅，均为无机材料，从本质上来说就耐侯性好且耐酸耐碱耐水，强于现有技术的有机涂料。（2）本发明的整体厚度不超过3mm，加之利用硅藻生长深入墙体后高温炭化获得的炭化纤维及硅胶胶粘结构增加结合力，墙面结合力好。（3）吸音系数0.4-0.5，吸音性能较好。（4）陶质疏孔结构及内置的炭化纤维、表面硬质阳极氧化的铝芯颗粒、填充的硅胶共同构建了自结合力好、高耐磨的整体涂层性能。（5）工艺环保、人体无害，不含有机胶粘剂，无毒性和挥发性。因而本发明具有降噪效果好、表面耐磨、耐紫外线、不易开裂脱落的特性。

①将蒙脱石、高岭土、铝粉混合均匀，并添加400kg-450kg的泡花碱水溶液，室温下搅拌均匀，获得湿热粘土；
②将步骤①获得的湿热粘土按质量比7：3分离，选取其中占比30%的部分均匀涂覆在外墙墙面上，涂覆厚度0.5mm-1mm，获得底层涂料；
③静置底层涂料1-2天至涂料固结，出现疏孔和裂纹，然后在涂料表面均匀喷涂含根管藻孢子浓度1×106cfu/ml-1×108cfu/ml的海水，至底层涂料含水量升至30%-40%，然后持续喷水保持湿度至底层涂料及裂纹中的墙体表面完全覆盖生长出致密褐色苔，获得待处理底层涂料；
④采用明火烘烤待处理底层涂料至涂料再次干结、褐色苔炭化，即获得所需底层涂料；

⑦将380V三相动力电源的三相电极分别施加在待处理涂覆层对应墙面的顶部两角和底部中间位置，然后将混合水溶液持续、均匀地喷淋在待处理涂覆层表面，使待处理涂覆层含水量保持60%-65%，保持2h-3h，然后停止喷淋，获得初处理涂层；
⑧保持通电，将剩余的泡花碱水溶液均匀喷涂在初处理涂层表面，喷涂完后立即停止通电，自然干燥后，即获得所需降噪耐磨抗老化外墙涂料。
