Description
技术领域
本发明公开了一种耐水型岩棉保温板,属于建筑材料技术领域。
背景技术
随着经济的飞速发展,各类建筑物建造速度和规模都达到了空前的高度,为了使建筑物能够达到环保节能的要求,需要对建筑外墙进行加装保温板材。岩棉是一种优质高效的保温材料,它具有良好的保温隔热、隔声及吸声性能,与传统的保温材料相比,具有密度小、导热系数低、不燃烧、防火无毒、适用范围广、化学性能稳定、使用周期长等突出优点,是目前公认的理想保温材料。岩棉是以天然岩石为主要原料,经高温溶化、纤维化、越板成型及制品后加工而成的隔热保温材料。在工业热力设备上,采用单位立方的岩棉进行保温,平均节省能量2900W,相当于每年节省3t标准煤。岩棉保温材料对确保热能设备及工艺装置稳定运行、降低风险、节能减排等也起到了关键的作用。但传统岩棉绝大部分是用于蒸汽管道和炉墙的保温,其质量与大规模用于墙体保温的要求还相差甚远,评价外墙外保温系统性能的参数有很多,其中,透湿性和防水性就是评价其性能优越与否的重要参数之一。外墙外保温系统在热湿迁移的过程中,若其内部湿份不断累积,不能及时疏散,不仅会导致保温系统的导热系数增大,降低其保温效果。同时,系统内积累的湿份遇冷时会有结露的风险甚至结冰,这将大大降低外墙外保温系统的使用寿命。
岩棉板板主要以经摆锤法生产的憎水型岩棉板板为保温隔热层材料,岩棉板复合板是以天然岩石如玄武岩、辉长岩、白云石、铁矿石、铝钒士等为主要原料,加适量的粘结剂、憎水剂经高温熔化、纤维化而制成的无机质纤维;矿渣岩棉板棉是以工业矿渣如高炉的矿渣、磷矿渣、粉煤灰等为主要原料,经过重熔纤维化而制成的无机质纤维。岩棉板板具有保温、防火阻燃、隔热、隔音等优点,因此得到了广泛的应用,尤其在20世纪70年代开始广泛的用于冶金、机械、建材、石油、化工工业,用于外墙保温已有近30年的历史,而由于其生产成本及造价较高,经济成本大于有机保温材料,这就限制了其使用范围。因此,针对目前传统的岩棉板还存在的保温性能和防水性能不佳的问题,需进行进一步研究。
发明内容
本发明主要解决的技术问题是:针对传统岩棉板保温性能和防水性能不佳的问题,提供了一种耐水型岩棉保温板。
为了解决上述技术问题,本发明所采用的技术方案是:
一种耐水型岩棉保温板,包括岩棉保温层、防水层,
所述岩棉保温层是由以下重量份数的原料组成:60~80份岩棉,2~3份憎水剂,20~30份水,10~20份改性添加料,20~30份耐高温粘结剂;
所述防水层是由以下重量份数的原料组成:30~50份改性海藻酸钠液,8~10份干性油,3~5份乳化剂,80~100份无机粘结剂,60~80份水;
所述耐水型岩棉保温板具体制备步骤如下:
所述岩棉保温层是由以下重量份数的原料组成:60~80份岩棉,2~3份憎水剂,20~30份水,10~20份改性添加料,20~30份耐高温粘结剂;
所述防水层是由以下重量份数的原料组成:30~50份改性海藻酸钠液,8~10份干性油,3~5份乳化剂,80~100份无机粘结剂,2~3份植物精油,60~80份水;
所述耐水型岩棉保温板具体制备步骤如下:
(1)按防水层原料组成称量各原料,将改性海藻酸钠液,干性油,乳化剂,无机粘结剂,植物精油和水搅拌混合均匀后,涂布于岩棉保温层表面,控制涂布厚度为0.3~0.5mm;
(2)待涂布结束,用液氮喷淋冷冻后,高温烘干,出料,即得耐水型岩棉保温板。
所述憎水剂是由以下重量份数的原料组成:60~80份固含量为15~20%聚硅氧烷乳液,10~30份固含量为10~15%硅丙乳液LR-7220。
所述改性添加料的制备过程为:将空心玻璃微珠与氢氧化钠溶液搅拌混合,过滤,洗涤,干燥,得预处理空心玻璃微珠,按重量份数计,将20~30份预处理空心玻璃微珠,2~3份玉米淀粉,0.2~0.3份巴氏芽孢杆菌菌液,2~3份尿素,30~50份水混合发酵,接着加入预处理空心玻璃微珠质量0.2~0.3倍的硝酸钙溶液,搅拌混合,过滤,高温处理,降温,即得改性添加料。
所述耐高温粘结剂为ZS-1071耐高温无机粘合剂或ZS-1072耐高温膨胀胶中的任意一种。
所述改性海藻酸钠液的制备过程为:将海藻酸钠与水按质量比1:50~1:100混合,静置溶胀后,加热搅拌溶解,接着加入海藻酸钠质量0.02~0.03倍的高碘酸钠,加热搅拌反应,即得改性海藻酸钠液。
所述干性油为桐油,梓油或亚麻油中的任意一种。
所述乳化剂为烷基酚聚氧乙烯醚,高碳脂肪醇聚氧乙烯醚,椰子油酸,脂肪酸或二乙醇胺中的任意一种。

所述植物精油为白菊精油,迷迭香精油,五味子精油,薰衣草精油,玫瑰花精油,茉莉花精油,茶花精油或雪莲精油中的任意一种。
本发明的有益效果是:
(1)本发明通过添加改性添加料,在制备过程中,首先,空心玻璃微珠经过氢氧化钠溶液浸泡,氢氧化钠与空心玻璃微珠表面的二氧化硅反应,使得空心玻璃微珠的粗糙程度得到改善,接着将预处理空心玻璃微珠,玉米淀粉,巴氏芽孢杆菌菌液,尿素,水混合发酵,由于空心玻璃微珠具有良好的粗糙程度,使得巴氏芽孢杆菌能够在空心玻璃微珠表面繁殖,接着通过添加硝酸钙溶液,巴氏芽孢杆菌在新陈代谢过程中产生脲酶,脲酶可将体系中的尿素分解生成碳酸根离子和铵根离子,由于巴氏芽孢杆菌细胞壁表面带负电荷,体系中的钙离子会被巴氏芽孢杆菌细胞壁吸附,从而以细胞为晶核,在细菌周围会生成碳酸钙,在空心玻璃微珠表面形成碳酸钙微球,添加到体系中后,使得体系的孔隙率得到提升,从而使得体系的保温性能得到提升;
(2)本发明通过添加改性海藻酸钠液和改性添加料,在使用过程中,改性添加料表面的碳酸钙微球,生成的碳酸钙受热生成氧化钙,氧化钙与体系中的水反应,生成氢氧化钙,使得体系中溶出部分钙离子,钙离子能够促使改性海藻酸钠液交联,从而使得棉保温层与防水层间的界面结合强度得到提升,从而使得体系的防水性能得到提升,同时,由于改性添加料表面的碳酸钙,使得改性添加料表面的粗糙程度得到提升,使得改性添加料间易形成机械咬合,而交联网络使得添加料间的咬合程度得到提升,使得体系的致密度得到进一步的提升,从而使得体系的防水性能得到进一步的提升;
(3)本发明通过添加干性油和改性添加料,在使用过程中,由于改性添加料表面的附着碳酸钙微球,使得干性油和改性添加料表面的接触面积增大,使得干性油能够良好的润湿改性添加料,接着干性油氧化交联,使得改性添加料间的界面结合强度得到提升,使得体系的致密度得到进一步的提升,从而使得体系的防水性能得到进一步的提升。
