Description

高达因值电池盒底板制备方法
技术领域
本专利涉及装载动力电池的电池盒的底板的制备方法。
背景技术
新能源车辆中的动力电池是安装在电池盒内的。电池盒底板的上表面(位于电池盒内部的内表面)要与电池的电极板粘接。
电池盒底板除了要有好的绝缘耐压、耐冲击、阻燃等性能外，还需要其上表面达因值较高，具有良好的粘接工艺性，以便于涂胶与电极粘接。
聚氨酯泡沫具有绝热效果好，比强度大，电学性能、耐化学药品以及隔音效果优越等特点。
聚氨酯泡沫是以异氰酸酯和聚醚为主要原料，在催化剂等多种助剂的作用下，通过混合、发泡而成的高分子聚合物。聚氨酯蜂窝板玻纤复合材料已经广泛应用于汽车天窗、备胎盖板、行李箱隔板、搁物板等多个部位。聚氨酯蜂窝板玻纤复合材料具有重量轻、弯曲强度大、尺寸稳定性好、耐腐蚀、生产效率高等优点，可大大节约原料成本和制造成本。聚氨酯蜂窝板玻纤复合材料一般采用喷涂布料，模压发泡成型的工艺。常规操作过程是：由发泡机将A组分(白料)、B组分(黑料)混合后均匀喷涂在铺设玻毡的蜂窝板上，送入预热的模具，经模压反应成型后取出零件，修边。
但是聚氨酯蜂窝板玻纤复合材料的表面达因值一般只有20-28，无法满足与电极粘接的要求。另外，聚氨酯蜂窝板玻纤复合材料中蜂窝板一般为纸板或者pp板，聚氨酯蜂窝板玻纤复合材料的机械性能较低，不能满足电池盒底板的要求。
发明内容
本发明的目的是提供一种高达因值电池盒底板制备方法，其制备的电池盒底板上表面达因值不小于45，且具有良好的抗拉强度、屈服强度、弯曲强度及绝缘耐压性能。
为达到上述目的，本发明采用如下技术方案：
高达因值电池盒底板制备方法，玻纤表面毡铺设在玻纤方格布上形成组合层，黑料中含有异氰酸酯，白料中含有聚醚多元醇，其特征是：白料中还含有蒙脱土和交联聚维酮，聚醚多元醇、蒙脱土、交联聚维酮的重量比是85：1.0-1.8：1-5；把钢板放置在热压机的模腔底部；把混合有黑料和白料的聚氨酯原料喷涂在玻纤表面毡上，并使得聚氨酯原料渗透至玻纤方格布上；把组合层放置在钢板上热压、冷却成型得到毛坯；对毛坯的非钢板表面进行激光处理，激光处理时工件表面的能量密度6.0-6.5J/cm2。
作为对上述的高达因值电池盒底板制备方法的改进，聚醚多元醇、蒙脱土的重量比是85：1.4-1.5。
作为对上述的高达因值电池盒底板制备方法的改进，聚醚多元醇、交联聚维酮的重量比是85：2-3。
作为对上述的高达因值电池盒底板制备方法的改进，激光处理时工件表面的能量密度6.2J/cm2。
作为对上述的高达因值电池盒底板制备方法的改进，所述钢板的厚度不超过1mm；热压时，靠近钢板的下模温度110℃±5℃，远离钢板的上模温度120℃±5℃，时间240s±10s，压力-18-22Mpa；热压后取出冷却。
作为对上述的高达因值电池盒底板制备方法的改进，玻纤表面毡的克重是30-50g/m2，玻纤方格布的克重700-800g/m2。
本发明的有益效果：本发明在聚氨酯发泡的白料、黑料中适当添加了蒙脱土和交联聚维酮，提高了毛坯表面达因值，并对毛坯表面进行激光处理，进一步提高了表面达因值。同时，把钢板与喷涂聚氨酯原料的组合层经过热压有机复合，提高了组合层与钢板的剥离强度，并具有良好的高强度及绝缘耐压性能，可以作为动力电池盒的底板使用。
具体实施方式
实施例：高达因值电池盒底板制备方法。
聚氨酯原料包括黑料和白料。黑料采用粗MDI，150份。白料中包括，以甘油为起始剂、环氧丙烷为聚合单体、环氧丙烷封端的聚环氧丙烷聚醚多元醇，65份；以蔗糖为起始剂、环氧丙烷为聚合单体、环氧乙烷封端的聚醚多元醇，20份；表面活性剂SC815(万华化学集团股份有限公司生产)，1份；催化剂三亚乙基二胺，1份；交联剂三乙醇胺，5份；扩链剂2-甲基-1，4丁二醇，3份；水，2份；阻燃剂三氯乙基磷酸酯(TCEP)，3份；浙江丰虹膨润土有限公司生产的粒径0.075mm的蒙脱土(重量份数参见表1)，交联聚维酮(重量份数参见表1)。
把克重约40g/m2玻纤表面毡铺设在克重740-760g/m2的玻纤方格布上的形成组合层。把聚氨酯原料均匀混合后喷涂在玻纤表面毡上，喷涂量约800g/m2，使得聚氨酯原料渗透至玻纤方格布上。
把厚度0.8mm的钢板放置在热压机的模腔底部。
把组合层放置在钢板上热压。热压时，靠近钢板的下模温度110℃±5℃，远离钢板的上模温度120℃±5℃，时间240s±10s，压力20Mpa左右。然后取出冷却得到毛坯。
对毛坯的上表面(非钢板表面)进行激光处理，增加表面张力，并去除表面残留的脱模剂，得到高达因值电池盒底板。激光处理时采用脉冲激光器，脉冲频率：230kHz；脉冲能量：1.2MJ；脉冲宽度：10微秒；工作距离234mm；毛坯上表面的能量密度6.2J/cm2。激光处理时采用江苏维力安智能科技有限公司生产的激光处理设备。对激光处理前后的工件上表面达因值进行测试，发现激光处理后上表面达因值(详见表1)比激光处理前一般高15-20。
各实施例制备的电池盒底板的密度4.6±0.2g/cm3(GB/T1464-2005)；抗拉强度
≥500MPa、屈服强度≥300MPa、弯曲强度≥300MPa(GB/T1447-2005)；滚筒剥离强度：组合层与钢板的平均剥离强度190N·mm/mm(GB/T1457-2005)；热变形温度：按照GB/T1634.2-2004，升温速率(120±10)℃/h，施加的弯曲应力为1.8MPa，结果满足＞200℃；热失控后(800℃，0.5h)的绝缘耐压：耐电压100OV/DC，60s，漏电流≤1mA，满足电池盒底板的使用要求。
由表1可以看出，仅仅添加蒙脱土或者交联聚维酮对于工件表面达因值的提高很有限，只有在聚醚多元醇、蒙脱土、交联聚维酮的重量比是85：1.4-1.5：2-3，且进行激光处理后达因值可以达到50以上。
