Description

一种智能感光窗帘及制备方法
技术领域
本发明涉及室内装饰技术领域,具体涉及一种智能感光窗帘及制备方法。
背景技术
窗帘的主要作用是与外界隔绝,保持居室的私密性,同时它又是家装不可或缺的装饰品。冬季,拉上幔帐式的窗帘将室内外分隔成两个世界,给屋里增加了温馨的暖意。现代窗帘,既可以减光、遮光,以适应人对光线不同强度的需求;又可以防火、防风、除尘、保暖、消声、隔热、防辐射、防紫外线等,改善居室气候与环境。因此,装饰性与实用性的巧妙结合,是现代窗帘的最大特色。但传统窗帘需自己手动打开、关闭,在人们上班、上学过程中,人们无法及时关闭窗帘,导致强烈的阳光透过窗户暴晒房间内的家具等,久而久之,家具提前老化损害,降低其经济效益。
传统的窗帘开合都要人为地操作,而且对房间的亮度控制不精确,既费时费力,又没有达到通过精确调节房间亮度来最优化生活、办公的目的,甚至有些能通过按键来调节窗帘的开合程度,虽然省去了人工实际动手操作的麻烦,但窗帘实际进入到房间的光照强度并没有得到精确地控制,因此研究开发一种能够智能调节窗帘的光照透过率,为人们提供适宜的工作生活环境的窗帘具有重要意义,也符合目前市场需求,具有较好的应用前景。
发明内容
针对现有技术中的缺陷,本发明的目的是提供一种智能感光窗帘及制备方法,所述窗帘不仅能够调节外界照射进室内的光源,保证一定的光照透过率,为人们提供最适应的生活、工作光照强度,还具有较好的防水防尘效果,此外,所述窗帘外观美观的,突破了以往单调的色彩,为生活增添了活力。所述制备方法简单易行,具有较好的应用价值。

所述凹凸棒土为天然凹凸棒土经提纯、热改性之后配置得到的膏状凹凸棒土。
本发明所述智能感光窗帘的方法,包括如下步骤:
(1)感光变色涂料层的制备:按照配比分别称取聚氨酯、环氧树脂及适量的水加入到反应釜中,升温至90℃,加入石墨烯,搅拌反应1h,然后再加入感光变色添加剂、羟丙基甲基纤维素、消泡剂搅拌50min,再置于转速为4000转/min的剪切机中剪切10min,即得所述感光变色涂料;
(2)吸光涂料层的制备:按照配比分别称取二氧化硅、氧化镁、二氧化钛、氧化铝粉碎至100~150目,混合均匀,然后置于球磨机中研磨5h,的混合物a1;
按照配比称取聚氨酯、聚丙烯酰胺和适量水加入到反应釜中,加入混合物a1搅拌均匀,再加入膏状凹凸棒土和消泡剂,混合均匀后置于转速为4000转/min的剪切机中剪切20min,即得所述吸光涂料;
(3)感光窗帘的制备:在基布层上表面涂覆感光变色涂料层,然后在感光变色涂料层上表面涂覆散光涂料层;在基布层的下表面涂覆吸光涂料层,烘干后,即得所述感光窗帘。
步骤(1)中加入的石墨烯的方法为加入浓度为0.5g/L的石墨烯水溶液,使得石墨烯与聚合物能够更好的混合。
步骤(2)中膏状凹凸棒土的制备方法为:取天然凹凸棒土进行粉碎至200~300目,加入凹凸棒土质量20倍的水,搅拌形成悬浮泥浆,取上层悬浊液于5000转/min的离心机中离心处理5min,真空抽滤;将滤饼烘干,然后置于1000℃的马弗炉中焙烧2h,冷却后研磨至粒径为200~300目,再加水配置成膏状凹凸棒土,所述膏状凹凸棒土中含水量为80%。
本发明所述的智能感光窗帘,在散光和吸光双层涂层的作用下,调节外界照射进室内的光线,保证一定的光照透过率,为人们提供最适应的生活、工作光照强度。当光线很强时,首先光照照射在窗帘散光层上,将光线分散,散射后部分光线照射到下一层感光变色层,感光变色层开始变色并反射部分光线,剩余光线在照射至光线吸附层,经光线吸附层吸附后,剩余光线才传至室内;当外界光线很弱时,光线照射到窗帘上,仅在散光涂层上将光线打散,弱光线照射在感光变色层和吸光涂料层时,由于捕捉不到强光,使得光线经过时不会有太多消耗直接照射到室内,从而使得不管外界光线的强或弱,所述感光窗帘均能保证一定的光照透过率,使得传至室内的光线温和、不刺眼,既能保证人们有足够的亮光进行工作或者生活,又不会造成晒伤或者使得夹具老化,具有智能化调节作用,符合以人为本的设计理念,具有较好的使用价值;所述智能感光窗帘还具有较好的防水、防尘效果,且具有容易擦洗的特点,大大降低了护理难度,此外,所述窗帘外观美观的,突破了以往单调的色彩,为生活增添了活力。
以上对本发明的具体实施例进行了描述。需要理解的是,本发明并不局限于上述特定实施方式,本领域技术人员可以在权利要求的范围内做出各种变形或修改,这并不影响本发明的实质内容。
