Description

高硬度高亮度防霉瓷砖专用胶
技术领域
本发明涉及一种瓷砖专用胶，特别是一种高硬度高亮度防霉瓷砖专用胶。
背景技术
瓷砖专用胶是一种专用密封胶。墙面贴瓷砖传统方法是用水泥砂浆，应用较广泛，由于这种施工方法费时费力，且对工人技术要求高，因此瓷砖胶等粘合剂正逐渐取代水泥砂浆施工。但是现有的瓷砖胶固化后表面光反射率较低，与传统的水泥砂浆类似，施工后瓷砖接缝处与瓷砖本身反光差异明显，美观程度较差。
发明内容
针对上述现有技术的不足，本发明的目的是提供一种高硬度高亮度防霉瓷砖专用胶，使其固化后具有高硬度、高反光、防霉的特点，以适合室内装饰使用。
技术方案：本发明提供以下技术方案：一种高硬度高亮度防霉瓷砖专用胶，按重量百分比计包括以下组分：硅烷封端的聚氨酯10～50％、增塑剂1～20％、填料30～70％、乙烯基三甲氧基硅烷1～3％、甲基三甲氧基硅烷1～3％、硅烷偶联剂1～3％、有机锡催化剂0.1～0.5％。
进一步的，所述硅烷封端的聚氨酯分子量为2000～5000。
进一步的，所述填料为碳酸钙或石英粉。
进一步的，所述增塑剂为DINP、DIDP和聚醚中的任意一种或任意多种的混合物。
进一步的，所述硅烷偶联剂为KH540和KH792中的任意一种或两种。
优选的，所述有机锡催化剂为二月桂酸二丁基锡。
有益效果：本发明与现有技术相比：
1、聚合物中有-NCO基团，可以实现永久性防霉，适用于室内潮湿环境长久使用而不霉变。
2、固化后瓷砖胶具有高硬度高亮度特性，表面反光率大于50％，保持和瓷砖一个颜色，保持和瓷砖接近的硬度，便于清洗。
3、不存在游离的-NCO集团，可以实现对人体无害，符合环保要求。
