Description
技术领域：
本发明涉及建筑涂料技术领域，具体涉及一种环保型可调节室内湿度的内墙腻子。
背景技术：
内墙腻子处于墙体找平砂浆与涂料层之间，起进一步找平和形成装饰性纹理图案的辅助作用。市场上常见的腻子粉多以白水泥、惰性填料、化学添加剂为主要成分，通过均匀混合得到，这种干粉材料按要求直接加水搅拌成膏状即可刮涂施工，然而以水泥为胶结料的传统腻子不可避免地存在水泥基材料易收缩开裂、起壳、剥落等缺陷。近年来，在已报道的一些专利中以建筑石膏及脱硫石膏、氟石膏作为基料制备腻子，但是仍存在稳定性不佳、强度和硬度达不到具体施工要求等缺点。
发明内容：
本发明所要解决的技术问题在于提供一种使用方便、干燥速度快且性能优异的环保型可调节室内湿度的内墙腻子。
本发明所要解决的技术问题采用以下的技术方案来实现：
一种环保型可调节室内湿度的内墙腻子，由如下重量份数的原料制成：
石膏粉60-70份、丙烯酸20-25份、火山灰10-15份、植物淀粉10-15份、歧化松香8-12份、陶瓷微粉6-10份、十二碳醇酯6-10份、卡波树脂5-8份、聚丙烯酰胺5-8份、气相二氧化硅4-6份、糯米胶4-6份、微晶蜡3-5份、炉甘石粉3-5份、羟丙基甲基纤维素2-3份、纳米胶粉2-3份、氢氧化钠2-3份、二亚乙基三胺0.3-0.5份、过硫酸钾0.2-0.3份、水50-70份。
其制备方法如下：
(1)向水中加入植物淀粉，不断搅拌下加热至70-80℃保温30min，再加入氢氧化钠搅拌使其完全溶解，然后加入丙烯酸、二亚乙基三胺和过硫酸钾，混合物继续加热至回流状态保温搅拌1h，待自然冷却至室温后送入冷冻干燥机，所得固体经粉碎机制成粉末，即得物料I；
(2)向歧化松香中加入微晶蜡和纳米胶粉，先加热至80-90℃保温混合10min，再加入陶瓷微粉、十二碳醇酯和卡波树脂，继续加热至120-130℃保温混合10min，待自然冷却至室温后即得物料II；
(3)向石膏粉中加入火山灰、气相二氧化硅和炉甘石粉，加热至100-110℃保温混合15min，待自然冷却至40-50℃后加入物料I、物料II、聚丙烯酰胺、糯米胶和羟丙基甲基纤维素，充分研磨使其混合均匀。
本发明的有益效果是：
(1)环保性强：不含甲醛、无毒性，涂抹于内墙后不会释放出有害气体；
(2)调节室内温度：当室内湿度过大时吸收空气中的水分，使室内的湿度降低；当室内湿度过小时释放水分，使室内的湿度增加，从而起到调节室内湿度的作用；
(3)使用方便：直接加水搅拌后即可使用，解决了现场配制腻子存在的原料质量不稳定和计量不准的问题，且干燥速度快；
(4)性能优异：能与各种基面粘结牢固，粘结强度不低于0.25MPa，附着力强，不燃、不起粉、不开裂、不脱落、光洁细腻，并且不会影响后续涂料的涂覆，不会导致彩色涂料褪色。
具体实施方式：
为了使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合具体实施例，进一步阐述本发明。
