具体实施方式
下面结合附图和实施例对本发明作进一步的说明，但并不作为对本发明限制的依据。
实施例1。高柔性水性聚氨酯整理剂的制备工艺及装置，构成如图1-2所示，包括以下步骤：
S1，在反应釜体1中加入以底物质量比计50-70％的聚酯二元醇、30-50％异佛尔酮二异氰酸酯及催化剂，升温至60摄氏度，反应1小时得A品；
S2，将A品升温至75摄氏度，并加入端羟基聚醚硅油及扩链剂1，4-丁二醇反应1.5小时，得B品；
S3，将B品降温至0-5摄氏度，加入丙酮调节体系粘度，接着加入三乙胺中和反应30分钟，然后加入乙醇反应40分钟后进行乳化。
用于高柔性水性聚氨酯整理剂制备的装置,包括反应釜体1，所述的反应釜体1上侧设有驱动机构2，驱动机构2下侧连接位于反应釜1中的搅拌机构3，反应釜体1外侧设有保温套5，反应釜体1和保温套5间设有保温腔6。
所述的驱动机构2包括设置于反应釜体1上侧的固定座4，固定座4中部设有竖直设置的往复丝杆7，往复丝杆7上设有连接搅拌机构3的丝杆座8。
所述的固定座4两侧设有用于对丝杆座8限位的导向槽10，丝杆座8两侧设有与导向槽10相对于的滑块11。
所述的搅拌机构3包括与丝杆座8连接的移动座12，移动座12上设有驱动电机13，驱动电机13通过竖轴14连接搅拌轴15，搅拌轴15上设有搅拌叶片16，搅拌叶片16上设有带转动叶片17的轮盘18。
所述的转动叶片17上开设有倾斜设置的导向孔23。
所述的保温套5上端设有冷却液进口19，保温套5下端设有排液口20。
所述的保温腔6为螺旋形的保温腔6，保温腔6内设有与保温腔6相对于的加热丝22。
本发明的工作原理，在乳化前的步骤中需要控制反应釜体1中的温度，反应釜体1内设有温度传感器，在温度传感器检测到反应釜体1温度过高时，通过向冷却液进口19加入冷却液，冷却液可以沿保温腔6流动，使反应釜体1内的温度均匀下降，保温腔6原有液体可以从排液口20排出，实现反应釜体1的快速降温，在需要升高温度时，通过加热丝22实现加热，接着在进行搅拌的过程中，驱动机构2可以实现搅拌机构3上下周期性运动，驱动机构2工作时，电机会驱动往复丝杆7转动，往复丝杆7转动的过程中，会带动丝杆座8沿导向槽10上下运动，导向槽10不仅能对丝杆座8起到导向作用，而且可以限制丝杆座8转动，使丝杆座8能沿往复丝杆7做上下往复运动，驱动机构2能带动搅拌机构3上下运动，使搅拌机构3能对反应釜体1内各个高度的原料进行搅拌，避免分层现象的发生，使乳化效果更好，搅拌机构3搅拌的过程中，搅拌叶片16可以对反应釜体1内的原料进行搅拌，搅拌的过程中，搅拌叶片16转动的过程中，轮盘18上的转动叶片17会发生转动，转动叶片17倾斜设置于轮盘18中，在搅拌叶片16绕搅拌轴15转动的过程中，转动叶片17会发生转动，对乳化原料进行分散，提升乳化效果。
