Description

一种地板铺装用高耐磨聚氨酯建筑密封胶及其制备方法
技术领域
本发明涉及密封胶技术领域，尤其涉及一种地板铺装用高耐磨聚氨酯建筑密封胶及其制备方法。
背景技术
密封胶是指引随密封面形状而变形，不易流淌，有一定粘结性的密封材料，是用来填充构形间隙、以起到密封作用的胶粘剂，具有防泄漏、防水、防振动及隔音、隔热等作用。建筑的***护、室内装饰装修、窗结构以及其它形式的围护和装饰结构是由单元组成，而单元之间产生的接缝绝大多数需要建筑用密封胶来密封填充。合理的建筑用密封胶选材和建筑密封的正确施工是保证建筑接缝密封成功必不可少的环节。
聚氨酯密封胶具有设备、工艺简单、无污染、粘接强度高、快速固化、施工方便等优点，在建筑领域得到广泛的应用。然而，现有的聚氨酯密封胶的耐候性较差，容易受紫外光老化，影响了其性能和使用寿命。CN201310164862公布了一种含木质素的聚氨酯密封胶，通过木质素替代三元醇合成聚氨酯密封胶，有效提高材料的耐光老化性能。然而在聚氨酯密封胶中引入木质素增加了密封胶的吸潮性，从而影响密封胶的稳定性。因此，有必要对其进行改进。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种具有优良耐候性以及高稳定性的地板铺装用高耐磨聚氨酯建筑密封胶及其制备方法。
本发明是通过以下技术方案实现的：
一种地板铺装用高耐磨聚氨酯建筑密封胶，其是由下述重量份的原料制得：
白炭黑20-30，刚玉粉20-30，木质素20-40，二硫化钼1-1.5，聚氧化丙烯二醇100-120，异佛尔酮二异氰酸酯30-60，二月桂酸二丁基锡0.5-1，固含量为30-40%的聚乙烯蜡乳液3-5，氨丙基三乙氧基硅烷3-5，正硅酸乙酯1.5-2.5，邻苯二甲酸二辛酯40-60，古马隆树脂1-2；
所述聚氧化丙烯二醇的数均分子量为2000-6000；
所述木质素为玉米秸秆木质素。
一种地板铺装用高耐磨聚氨酯建筑密封胶的制备方法，包括以下步骤：
（1）按重量称取原料，先将木质素溶解于聚氧化丙烯二醇中50-60℃加热处理2-4h，再于100-120℃真空除水1.5-2.5h，保持温度不变，加入氨丙基三乙氧基硅烷和正硅酸乙酯搅拌0.5-1h，得到复合聚氨酯预聚体；
（2）将白炭黑、刚玉粉和二硫化钼混合后按固液重量比1:1-1:1.5与水混合，加入聚乙烯蜡乳液搅拌10-15min，将得到的浆料进行喷雾干燥，其中喷雾干燥进风温度控制在160-180℃，得复合填料；
（3）先将步骤（1）中的复合聚氨酯预聚体与步骤（2）中的复合填料与50-60℃混合搅拌0.5-1h，然后加入其余原料80-90℃搅拌0.5-1h，即得地板铺装用高耐磨聚氨酯建筑密封胶。
本发明的优点是：
本发明通过向聚氨酯密封胶中引入木质素、氨丙基三乙氧基硅烷和正硅酸乙酯得到有机-无机杂化聚氨酯密封胶，利用木质素与硅氧网络相交联，既有效改善了材料的耐光老化性能，又能减少吸潮，提高材料的粘结强度和耐久性，同时，利用其余原料的复配与增效，使得到的聚氨酯建筑密封胶既具有优良的耐候性、粘接性能以及高稳定性，耐久性好，使用寿命长，还有高耐磨的特点，适合用于地板铺装。
