Description
技术领域
本发明属于保温防火材料技术领域，涉及一种岩棉装饰线条及其制备方法。
背景技术
装饰线条，是指挑檐线、腰线、窗台线、门窗套、压顶、遮阳弧、楼梯过梁、宣传栏边框、镜框线条等，是建筑装饰不可或缺的组成部分。现有的主要有木线条、石材装饰线条、仿石材装饰线条。其中仿石材装饰线条包括、EPS装饰线条、GRC装饰线条、PVC装饰线条、陶瓷装饰线条等。
其中EPS装饰线条是以聚苯乙烯泡沫(Expanded Polystyrene，简称EPS)为芯体骨料，外辅网格布和水泥砂浆等无机材料制成的建筑装饰材料，聚苯乙烯泡沫是一种轻型高分子聚合物。它是采用聚苯乙烯树脂加入发泡剂，同时加热进行软化，产生气体，形成一种硬质闭孔结构的泡沫塑料，具有轻质、保温、安装简易的优点。其缺点是力学性能和阻燃性能不够理想，防火等级不能达到A级，因此很多对防火等级要求较高的地方也限制使用。
GRC(Glassfibre Reinforced Concrete，简称GRC)是一种以耐碱玻璃纤维为增强材料，水泥砂浆为基体材料的纤维水泥复合材料，属于A1级防火材料，但是作为装饰构件存在易吸水，易开裂，不保温的缺点。
岩棉，是以玄武岩为主要原材料制作而成的，其具有质量轻、导热系数小、吸热、不燃等特点，也属于A1级防火材料，但是普通岩棉不具备防水能力，在使用过程中和施工后因吸湿、吸水量过大可造成板面松软、膨胀、粘接力下降，造成松散膨胀、分层等，继而导致保温效果不理想，难以满足建筑节能75％标准要求，故其使用范围受到限制。
基于此，现有的装饰线条中缺少同时兼具保温和防火性能的产品，开发能够兼具保温防火双重性能的装饰线条非常有必要。
发明内容
本发明提出一种岩棉装饰线条及其制备方法，解决了现有技术中装饰线条不能兼具保温防火性能的问题。
本发明的技术方案是这样实现的：一种岩棉装饰线条及其制备方法，包括由内到外依次设置的岩棉基材层、网格布层和砂浆层，按质量份数计，所述的岩棉基材层包括：140-160份岩棉纤维颗粒、10-25份膨润土、0.5-1.0份氯化钡、2-8份氟铝酸钠、7-15份氧化锌。
进一步地，按质量份数计，所述的砂浆层包括：30-60份硅酸盐水泥、10-30份砂、6-20份水、7-14份固化剂、1-2.5份羟丙基淀粉醚。
进一步地，按质量份数计，所述的固化剂包括12-15份聚乙烯亚胺、4-9份卡拉胶、15-20份粉煤灰。
进一步地，按质量份数计，所述的岩棉基材层包括：150-155份岩棉纤维颗粒、15-20份膨润土、5-8份氯化钡、5-8份氟铝酸钠、10-15份氧化锌。
上述保温防火型岩棉装饰线条的制备方法，包括以下步骤：
A.准备140-160份岩棉纤维颗粒、10-25份膨润土、5-10份氯化钡、2-8份氟铝酸钠、7-15份氧化锌；30-60份硅酸盐水泥、10-30份砂、6-20份水、7-14份固化剂、1-2.5份羟丙基淀粉醚，备用；
B.将膨润土、氯化钡、氟铝酸钠、氧化锌混合，得到混合物，将混合物和岩棉纤维颗粒在1400-1600℃熔化混合后转移至模具中，经挤压、拉伸、压制、降温固化后脱模，制备得到岩棉基材层；
C.将岩棉基材层切割成型，在其表面复合网格布，得到岩棉复合层；
D.硅酸盐水泥、砂、水、固化剂、羟丙基淀粉醚混合搅拌成砂浆，抽真空去除汽包，然后用模具挤出成型在线复合到岩棉复合层上，得到岩棉装饰线条。
本发明的工作原理及有益效果为：
1、本发明中保温防火型岩棉装饰线条由岩棉基材层、网格布层和砂浆层组成，通过对岩棉基材层和砂浆层的组分比例搭配设计，提高了岩棉装饰线条的保温性能，使得岩棉装饰线条兼具保温、防火双重效果，可以替代现有的GRC装饰线条和EPS线条。
2、本发明岩棉基材层中氯化钡和氟铝酸钠复配协同，使得氧化锌在岩棉基材层中更好地分散，还提升了岩棉基材层中各组分之间的结合力，使岩棉装饰线条单位面积上的总开裂面积由128-135mm2/m2降低至110-115mm2/m2，从而使得氧化锌的疏水性更好的发挥了出来，提高了岩棉基材层的防水性，进一步减弱吸水造成松散膨胀、分层的现象，最终提高了保温性能，同时氯化钡和氟铝酸钠因含有卤元素和铝元素，受热分解，捕捉自由基终止链反应，同时起吸热和稀释阻燃效应，并有抑烟效果，提高了岩棉装饰线条的耐火极限。
3、本发明试验中发现，岩棉基材层或水泥自身的氯离子扩散在砂浆体系中，导致砂浆层的耐久性差，尤其是空气湿度大、酸碱环境或者其他介质侵蚀时，更加危害砂浆，而加入的聚乙烯亚胺、卡拉胶、粉煤灰复配，抑制了氯离子的扩散，进而提高了砂浆层的耐久性，同时砂浆层固化剂中聚乙烯亚胺、卡拉胶、粉煤灰协同，提升了岩棉线条在潮湿状态下抗拉强度保留率，减小了导热系数，有效提高了砂浆层的强度和保温性能。

实际应用试验
按照JG/T483-2015《岩棉薄抹灰外墙外保温系统材料》中所述方法检测岩棉条性能指标，包括：潮湿状态下抗拉强度保留率，憎水率，导热系数，单位面积上的总开裂面积；采用JGJ/T193-2009混凝土耐久性检验评定标准中所述方法检测砂浆层的抗氯离子渗透性能，检测结果如表1所示。
表1
由上表1中实施例1和对比例1-4可知，实施例1相对于对比例1-4的潮湿状态下抗拉强度保留率、憎水率均有所提高，导热系数和开裂面积均减少，可见本发明岩棉基材层中氯化钡和氟铝酸钠复配协同，提高了各组分的结合力，增强了岩棉基材层的防裂性能，使得氧化锌的疏水性更好的发挥了出来，进而提高岩棉层的防水性，进一步减弱风化蚀变，吸水造成松散膨胀、分层的现象，继而提高保温性能，同时氯化钡和氟铝酸钠因含有卤元素和铝元素，受热分解，捕捉自由基终止链反应，同时起吸热和稀释阻燃效应，并有抑烟效果，通过GA/T 714-2007构件用防火保护材料快速升温耐火试验方法进行检测，实施例1-6的耐火极限为1.5h，对比例1-8耐火极限均在1h左右，可见，本发明通过对岩棉基材层和砂浆层的组分搭配设计，提高了岩棉装饰线条的耐火极限。
试验中发现，岩棉基材层或水泥自身的氯离子扩散在砂浆体系中，导致砂浆层的耐久性差，尤其是空气湿度大、酸碱环境或者其他介质侵蚀时，更加危害砂浆，检测结果实施例1-6的氯离子迁移系数1.5≤DRCM＜2.5，抗氯离子渗透性能等级均为RCMⅣ，对比例5-7的氯离子迁移系数DRCM≥4.0，抗氯离子渗透性能较差，可见本发明固化剂中聚乙烯亚胺、卡拉胶、粉煤灰复配，抑制了氯离子的扩散，进而提高了砂浆层的耐久性。
由对比例5-7和实施例1比较可知，砂浆层固化剂中未采用聚乙烯亚胺、卡拉胶、粉煤灰的岩棉装饰线条，与砂浆层固化剂中采用聚乙烯亚胺、卡拉胶、粉煤灰协同的岩棉装饰线条比较，采用聚乙烯亚胺、卡拉胶、粉煤灰协同的岩棉装饰线条在潮湿状态下抗拉强度保留率更高，导热系数更小，可见砂浆层固化剂中采用聚乙烯亚胺、卡拉胶、粉煤灰协同还提高了岩棉装饰线条的强度和保温性能。
以上仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
