Abstract
一种获得光聚合预聚物的装置,用于作为适合通过3D打印方法制造建筑或建筑部件的材料的组分。该装置包括在前体装载站和预聚材料接收器之间延伸的柔性闭环传送带,产品从该接收器中被卸载到建筑3D印刷机上。传送带携带多个能够绕闭环传送带的滑轮循环的柔性托盘。所述托盘是浅槽,其顶部是敞开的,装载着定量的前体部分,前体在从装载站到卸载站的途中,通过依次经过两个光聚合站的光源而被光聚合。当托盘通过卸载位置时,它们被倒置过来,使预固化的材料落入接收器。
Description
技术领域
本发明涉及一种用于获得光聚合预聚物的装置,更具体地说,涉及用于获得适合作为建筑材料组分的光聚合预聚物的上述装置。特别是,本发明旨在制备一种光聚合预聚物,用作通过3D打印方法制造建筑物或建筑部件,如墙壁、地板、天花板、外部和内部包层、家具等,或室外和室内特征等的材料组分。
背景技术
过去十年里,三维打印(以下简称3D打印)已经成为行业内的一个大热门词汇,甚至开始渗透到建筑业这样的领域。随着3D打印机现能够打印建筑墙体和加工水泥,该技术可以帮助重塑传统的建筑技术和产品。
3D打印在建筑领域的历史还不丰富。2004年,南卡罗来纳州的一所大学进行了一次尝试,通过3D打印生产了一面墙,这被广泛认为是该技术首次进入建筑领域。2014年,一座利用3D打印技术建造的全运河房屋在阿姆斯特丹完工。2016年,一座3D打印的豪宅在中国完成。同样在2016年,迪拜未来基金会通过3D打印技术建造了其办公室,这被认为是该技术在商业建筑领域的一个重要里程碑。这座功能齐全的2700平方英尺的建筑是由一台大型3D打印机建造的,尺寸为120x 40x 20英尺。施工仅用了17天。
3D打印在建筑领域的好处有以下几点:速度快、减少浪费、设计自由、减少人为错误。3D打印在建筑领域的挑战是成本高、劳动力短缺、质量控制和缺乏适当的法规。
尽管如此,在专利文献中已经提到了3D打印在建筑中的应用,包括通过光聚合来固化起始可聚合材料的聚合体系。
因此,2016年7月19日授权给P.Xu等人的第9,394,441号美国专利披露了一种用于三维打印系统的构建材料。该材料由可固化的低聚物材料、反应性成分、包括一种或多种聚氨酯蜡的非反应性成分和至少一种稀释剂组成。该材料的反应成分是至少一种化学分子,可与低聚物固化材料和/或至少一种稀释剂中含有的化学分子聚合。反应性成分以结晶区的形式存在于构建材料中。
尽管第9,394,441号美国专利没有明确地教导可聚合材料通过光聚合进行固化,但可以假设提供了这样的固化方法。据称,在一些实施方案中,合适的光引发剂包括那些可与HeCd激光辐射源一起使用的光引发剂,包括苯乙酮,适宜地为2,2-二烷氧基苯乙酮和1-羟基苯基酮,例如1-羟基环己基苯基酮或2-羟基异丙基苯基酮(=2-羟基-2,2-二甲基苯乙酮)。
此外,在一些实施方案中,合适的光引发剂包括那些可与氩激光辐射源一起使用的光引发剂,包括苄基酮,如苄基二甲基缩酮。在一些实施方案中,光引发剂包括α-羟基苯基酮、苄基二甲基缩酮或2,4,6-三甲基苯甲酰基二苯基氧化膦或其混合物。

发明简述
发明涉及一种用于获得光聚合预聚物的装置和方法,该光聚合预聚物用作适合通过3D打印工艺制造建筑物或建筑部件,如墙壁、地板、外部和内部包层、家具等,或室内和室内特征等的材料组分。
该装置包括闭环传送带,其为在前体装载站和预聚材料接收器之间延伸的柔性带形式,产品从所述接收器卸载到建筑3D打印机。该传送带携带多个能够绕所述闭环传送带的滑轮循环的柔性托盘。其中一个滑轮是驱动滑轮,其配备了驱动电机。所述托盘是浅槽,其顶部是敞开的,承载着定量的前体部分,这些前体在从装载站到卸载站的途中,通过依次经过两个光聚合站的光源而被光聚合。
换句话说,传送带或柔性带在未处理材料(前体)装载站的一侧有装载位置,在与装载位置相反的一侧有卸载位置,其中,当材料接收托盘通过卸载位置时,材料接收托盘被倒置过来,即变成托盘的开口顶部朝下的位置。
每个站由多个发光装置(LED)组成,以预定的波长工作,用预定剂量的光能照射装入托盘的材料,使材料达到预期的粘度。该过程的参数(粘度、辐射剂量等)通过中央处理单元由传感器自动控制。在卸货之前,未固化的液相与预聚物分离,并被送回装载站重新使用。

具体实施方式
本发明涉及一种用于获得光聚合预聚物的装置,更具体地说,涉及用于获得适合作为建筑材料组分的光聚合预聚物的上述装置和方法。特别地,本发明旨在制备适于用作通过3D打印方法制造建筑物或建筑部件(如墙壁、地板等)的材料组分的光聚合预聚物。
本发明的装置(以下仅称为"装置")以示意图的形式示于图1,并记作附图标记20。该装置旨在制备光聚合有机材料,以在通过3D打印制造建筑物或建筑部件时与其他组分混合使用。该装置20旨在提供可光固化的光聚合材料的连续和有效的预聚合,方法是在安装在可光聚合材料途中的光源照射预聚合材料的作用下,将该材料从起始材料装载器传送到预聚合材料输出站。
更具体地说,如图1所示,装置20包括闭环传送带22形式的输送单元,例如,从装载位置(即可预聚材料输入站24)延伸到与装载位置相反的一侧的卸载位置(即预聚材料输出站26)的柔性皮带。
输入站配有储罐27,其中含有液态的起始可光预聚材料28和悬浮在液态介质中的固体PEG 4000粉末。
闭环传送带22,即柔性带,被引导绕滑轮30和32循环,其中一个(如滑轮30)是驱动滑轮,另一个(即滑轮32)是从动滑轮。滑轮30由电机34通过驱动器(未显示)驱动旋转。传送带22的上部运行沿箭头A的方向移动(图1)。
附着在传送带22的表面上的是多个预聚托盘(以下称为"材料接收托盘")36a,36b,...36n(图1)。这些托盘可以以预定的距离相互间隔,也可以像拖拉机履带的链接那样相互连接。
从图2可以看出,该图是其中一个材料接收托盘的立体图,例如,托盘36a,该托盘是一个浅矩形槽,它有敞开的顶部,侧壁36al、36a2、36a3和36a4以及底板68。可以理解的是,材料接收托盘仅作为一个例子显示为矩形体,托盘可以是方形、六角形或任何其他合适的形状。由于托盘36a,36b,...36n被固定在传送带22上,即带,并应环绕过滑轮30和32,它们是由柔性材料制成的,例如硅胶,其对液态的可光聚合材料28具有化学惰性,并能绕滑轮循环。为了提高可光聚合材料的固化效率,侧壁36al、36a2、36a3和36a4的内表面以及底板68都涂有反射涂层。
换句话说,传送带22在未处理材料装载站的一侧有装载位置,在与装载位置相反的一侧有卸载位置,其中,当材料接收盘通过卸载位置时,材料接收盘被转为倒置位置,即转到托盘的敞开顶部朝下的位置。
装置20的一个重要部分是固定的预聚站38,该预聚站由依次排列在传送带22上方的第一预聚站38a和第二预聚站38b组成,以使材料接收托盘36a、36b、...36n在从材料输入站24到预聚材料输出站26的途中穿过它们。在中央处理单元40的控制下,材料接收托盘36a、36b、...36n以连续或间歇的方式通过预聚站38a和38b,该中央处理单元除其他外,通过反馈线42控制驱动滑轮30的驱动电机34的运行速度。
使用两个预聚站38a和38b,而不是一个,以便不中断该过程。如果其中一个站停下,另一个站继续工作,过程不会中断。还有一个理由认为,将光预聚过程分为两个阶段,可以更精细地选择最终产品的粘度。这一观点是基于光聚合动力学曲线具有指数形式的事实。在两个站的正常运行期间,它们的光能剂量以50%/50%的方式共享。如果只有一个站运行,它的负荷就会增加。此外,使用两阶段预聚合可以更好地控制预聚合过程,并有可能提高所获产品的质量。
填充在材料接收托盘36a、36b、...36n的可光聚合材料是通过定量阀44从输入站储罐27供应给这些托盘。在安装在各自预聚站38a和38b上的光源46和48发出的光的作用下,托盘中的材料通过光聚合进行预聚合,这些光源正好在材料接收托盘36a、36b、...36n的路径上方。
两个预聚站38a和38b的光源46和48提供的总光照功率在5到5000Wt之间。根据本发明的一个具体实施方案,在每个站中,LEDs以矩形或方形配置的平面矩阵的形式排列。这些LED可以在各种波长工作,如405纳米、440纳米等。对光源46和48的主要要求是为托盘中的材料提供高均匀度的照明,精确度在±5%范围内。每个光源46和48可以包括,例如,500个LED。可以理解的是,这个数量只是作为例子给出,最终的结果将由可预聚材料被照射的总剂量来确定。光源46和48可以是可替换的,并在相同或不同的波长下工作。
已知的是,不同的可光聚合前体对不同波长的光辐射会有不同的反应。因此,如上所述,光源46和48可以是可替换的,由不同波长的LED组成。例如,光源46和48可以在405纳米波长或440纳米波长下工作,或者其中一个可以在405纳米波长下工作,另一个在440纳米波长下工作。可以理解的是,具体的波长仅作为例子给出。
可以通过调整曝光时间和照明器的功率来达到获得具有可接受的最佳参数的最终产品的最佳剂量,以便随后使用所获得的预聚物与3D打印中使用的其他组分混合。换句话说,剂量D可以用以下公式表示:D=W·texp,其中W是可预聚材料被曝光的功率,texp是曝光时间。因此,D的值可以通过改变功率W、曝光时间texp或两者来调整。
在光发射器下停留的可光聚合材料的固化时间和发射的光功率强度,即辐射剂量,可以调整(例如,在2秒至60秒的范围内),并取决于所使用的材料和要接收的预聚合材料的粘度。
通过第二预聚站38b后得到的预聚材料是一种胶状物质,其粘度为30000至50000cPs(均质化后)。事实上,在这个阶段获得的材料由胶状物质和液体组成。粘度的选择是为了提供3D打印材料通过3D打印机的管道(图中未显示)的流动性,该3D打印材料是用所获得的预聚物制备的混合物。
预聚材料输出站26包括分离器50,当托盘绕过驱动滑轮32时,已经通过第二预聚站38b的预聚材料从托盘中落入所述分离器。分离器的内部被可翻转的滤网50c分成两个部分50a和50b,它将预聚材料的液态相传入50b部分,并将胶状相保留在50a部分。从50a部分,胶状相通过漏斗51被送入预聚材料接收器。在图示的情况下,预聚材料接收器被显示为破碎机,如粉碎机52。粉碎机52可以是传统的工业粉碎机,如Twin Shaft Wagner ShredderWTS500(奥地利)或类似产品。粉碎机将胶状物质破碎成具有例如1-10毫米尺寸的小块。
最终粉碎的预聚产品,是要与建筑物或建筑物部件的3D打印所需的矿物质或其他物质混合的组分之一,从装置中卸载到3D打印机(未显示)的最终预聚物接收器54。同时,积聚在50b部分的预聚材料的液态相在泵送装置56的作用下通过回流管道58返回到可预聚材料输入站24。最终的预聚物接收器54配有在线粘度计60,该粘度计在将其卸载到3D印刷机之前测量所获得的粉碎和均质化的预聚物的粘度。粘度计的一个例子是FungilabTMAlpha系列L型旋转粘度计,它可以快速准确地读取粘度。商标:FungilabTMV100003。
粘度计60通过反馈线62与中央处理单元40相连。如上所述,中央处理单元40可以控制和调整电机34的旋转速度,从而控制和调整传送带22的线速度,以及光源46和48的功率,从而控制和调整可光聚合材料的辐射剂量。
可以理解的是,预聚的预定程度,影响到将被卸载到3D打印设备中的粉碎和均质化的预聚物的最终可流动质的粘度和其他性能特性,取决于在光聚合过程中对材料的照射剂量,而该剂量由从预聚站38a和38b发射的光的功率和传送带22的速度所确定。由于在装置20中,最终产品的粘度取决于诸如传送带的速度、第一预聚站38a的曝光时间、第二预聚站38b的曝光时间、容器中起始材料28的粘度、可光聚合材料层的厚度等变量,因此在将装置设置为稳定模式的连续和自动操作之前,通过实验选择这些参数是有利的。
供选择地,每个托盘中所需要的材料层的厚度可以通过基于比尔-朗伯定律的计算来预先确定,该定律决定了平行单色光束在吸收介质中传播时的衰减情况。
换句话说,由于从预聚站38a和38b的发光器发出的光在层深方向上呈指数下降,知道了组件的光吸收常数,就有可以评估托盘中材料层的厚度。
送入输入站24的原料材料28是表1中列出的组分的液体混合物。材料28的粘度在5到15cPs之间,密度在1.0到1.2kg/l之间。
所生产的预聚物是一种胶状的均匀物质,其粘度在30000至50000cPs之间。这种材料具有改进的粘附性、环境抗性、低收缩性和短固化时间。这些特性的结合使其有可能在比使用传统预聚材料更短的时间内实现所需的3D打印结果。
表1.装置中使用的起始光聚合材料的特征
a)液态可光聚合材料以本领域已知的方式通过定量阀44控制的预定量被引入每个可移动托盘。在装载站,通过中央处理单元40向传送电机34发送的指令使各个托盘停止。
b)装载操作一完成,传送带就开始运动,直到托盘与第一预聚站38a的光源46正下方的位置对齐。
c)在第一预聚站38a,材料暴露在预定剂量的辐射下,使可光聚合材料预聚到第一期望的预聚程度。
d)在第一站进行预聚后,传送带22开始运动,并将装有预固化材料的托盘与第二预聚站38b的光源48对齐。
e)然后,在光源46阶段预固化的材料接受最后的固化,以达到所需的预聚程度。
f)步骤a)到e)连续进行,当沿着绕滑轮30和32的无尽循环路径前进时,托盘到达传送带的边缘并通过绕过滑轮32改变其方向,它将最终的胶状预聚材料投到分离器50的50a部分。获得的材料可能包含未固化的液态相。
g)在分离器50中,液态未固化相流入分离器50的50b部分,并在泵送装置56的作用下通过管道58返回到储罐27。
f)分离出来的均质的预聚材料,得到的预设粘度为30000至50000cPs,温度在30至40℃范围内,从分离器50的50a部分通过漏斗51被送入破碎机或粉碎机52,并从粉碎机送入预聚物接收器54,在那里预聚物的粘度由在线粘度计60控制。
g)最终的预聚物从接收器54沿箭头B的方向卸载到3D印刷机的混合器(未显示)。

因此,可以看出,选择最佳的辐照剂量对于制备比例分别为80升、40克和40克的TEGDMA、PRO和PEG组成的混合物的预聚是非常重要的因素。可以理解的是,这一结果是针对由TEGDMA、PPO和PEG组成的可预聚材料以及这些成分按预定比例的含量而获得的。
本发明已参照具体实例和附图进行了描述。应该理解的是,这些实施例和附图不应该被理解为限制本发明的应用范围,在所附专利权利要求的范围内,任何改变和修改都是可能的。例如,可以使用LED以外的、波长与上述不同的光源。托盘的形状可以与图2所示的不同。可以使用两个以上的预聚站。原始可光聚合材料的成分可以与表格和实施例中所示的成分不同。托盘不一定是柔性的。可以用脉冲泵代替定量阀来将定量的前体材料装入托盘。
