Description

一种磁悬浮列车缓冲块的制造方法
技术领域
本发明涉及聚氨酯制造领域，尤其涉及一种磁悬浮列车缓冲块的制造方法。
背景技术
随着我国工业的发展,新技术、新材料被大量地应用,汽车用橡胶材料已由普通橡胶向特种橡胶、橡塑共混胶发展。其中聚氨酯橡胶由于其耐磨性好,物理机械性能高,负载支撑容量大,减震效果好,日益得到广泛的应用，而目前在磁悬浮列车需要减震的场合一般采用弹簧和液压活塞并联的机械式减震器，弹簧起到缓冲的作用，活塞起到阻尼的作用，减震器通常是用来抑制施加于其上的外部的震动与冲击，使震动在减震器上产生较大的衰减，从而达到保持车辆或设备的舒适性和平稳性。该类减震器在长期使用后，其中的弹簧会因反复的弹性变形而产生松弛或者疲劳破坏，使减震器失效而无法使用；液压活塞的密封件会因磨损和老化而产生漏油现象，使减震器失去阻尼器的作用。因此需要提供一种接触式的减震缓冲块，安装位置空间需求量小，减震降噪效果好，动态疲劳性能好，重量轻，提高乘客乘坐的舒适性。
发明内容
本发明针对现有技术中占用空间大、减震降噪效果不佳的缺点，提供。
为了解决上述技术问题，本发明通过下述技术方案得以解决：
一种磁悬浮列车缓冲块的制造方法，其组分按质量份数计，包括以下步骤：
(1)配制A料：将40份聚四氢呋喃二醇，60份聚丙交脂二元醇添至搅拌罐中，再在搅拌罐中添加2～5份扩链交联剂搅拌10分钟，然后添加2～15份催化剂和1～3份硅油搅拌2小时得到混合物，后再次在搅拌罐中添加1～5份扩链交联剂搅拌10分钟，将混合物均匀地装桶并封入氮气，待用；
(2)配制B料：将260份聚四氢呋喃二醇加入搅拌桶中，将搅拌桶中的真空度调整为85kPa并于100℃的温度下真空搅拌脱水2小时，脱水完后于室温下冷却使搅拌桶中聚四氢呋喃二醇温度低于45℃，再在搅拌桶中加入100～200份异氰酸酯搅拌反应1～2小时，反应后自然冷却至反应产物温度在50℃以下，测异氰酸酯含量，若异氰酸酯含量达到目标值，将反应产物装入桶内并封入氮气，待用；
(3)将A料和B料都加入到发泡罐中，A料与B料的质量比为13：15～1:1，抽真空除气3～5min，倒入聚四氟乙烯模具中加工成型。
分批次添加扩链交联剂能使聚丙交脂二元醇和聚四氢呋喃二醇分别与不同的异氰酸酯反应扩链，具有增加材料的多样性复杂性从而达到良好的隔振效果。聚丙交脂二元醇和聚四氢呋喃二醇分别能与B组分的预聚体发生扩链反应，二者混合在一起反应，由于存在多种材质，混合增加了隔振降噪的效果，且添加的聚丙交酯二元醇使阻尼件更容易降解，对环境保护具有积极作用。
作为优选，步骤(1)所述的扩链交联剂为MOCA、MDA、DMTDA、DETDA、M-CDEA、TMP、丙三醇、MDI三聚体、乙醇胺、二乙醇胺、三乙醇胺、三乙醇胺、三异丙醇胶中的一种或多种。MOCA为3,3'-二氯-4,4'-二氨基二苯基甲烷，MDA为丙二醛，DMTDA为二甲硫基甲苯二胺、DETDA为3，5-二乙基-2，4甲苯二胺(约80％)与3，5-二乙基-2，6-甲苯二胺(约20.0％)两种异构体织成的混合物，M-CDEA为4,4'-亚甲基双(3-氯-2,6-二乙基苯胺)，TMP为磷酸三甲酯、丙三醇、MDI为4,4'二苯基甲烷二异氰酸酯。
作为优选，步骤(1)所述的催化剂为1,4-二氮杂二环[2.2.2]辛烷、三乙胺、二丁基二月桂酸锡、辛酸亚锡、N,N-二甲基乙醇胺中的一种或多种。
作为优选，步骤(2)中所述的异氰酸酯为异佛尔酮二异氢酸脂、二苯基甲烷二异氰酸酯的其中一种或其混合物。
本发明由于采用了以上技术方案，具有显著的技术效果：所得的磁悬浮列车缓冲块在往复压缩中产生的内生热少，而且分散热量的速度也比橡胶快，因此在实际应用中有更好的耐久性，且具有安装位置空间需求量小，减震降噪效果好，动态疲劳性能好，重量轻的优点，能大大提高乘客乘坐的舒适性，使用的材料与预聚体发生多种扩链反应，多种材料者混合在一起，增加了缓冲块隔振降噪的效果，且添加的聚丙交酯二元醇使阻尼件更容易降解，对环境保护具有积极作用。

表1圆柱形普通橡胶和圆柱形磁悬浮列车缓冲块的力学数据
试验表明，当圆柱体零件被压缩到高度的50％时，本发明所得零件压缩变形的横向尺寸增大的量只有原尺寸的12％，而橡胶零件变形增大的量则达到原尺寸的40％，说明所得的悬浮列车缓冲块安装位置空间需求量小，本发明所得零件的密度为0.35～0.70，橡胶减振缓冲块的密度是1.2～1.3。在实际应用中，本发明所得的聚氨酯缓冲块比橡胶缓冲块重量可减少50％以上；
试验表明，典型橡胶减振缓冲块的共振频率大约为50～55Hz，车内的噪音水平跟减振系统元件和路面噪音之间的共振频率有关，减振零件的共振频率离15～20Hz越远越好，本发明制造的缓冲块的共振频率发生在70Hz，因此能给车内提供更安静的环境。
