Description
技术领域
本发明涉及化工技术领域,特别涉及对蓄电池起到密封作用的一种基于乙基酯和甘油酯的高弹性蓄电池密封胶及制作方法。
背景技术
现有的蓄电池密封胶水的胺类固化剂存在易结晶且胶水可使用时间(胶水在一定温度下粘度升高至两倍的时间)短的问题,可使用时间体现了胶水的反应速度,决定客户配胶后胶水能使用和操作时间的长短,固化剂生产出来后在保质期内的结晶致使客户不能使用该产品。对蓄电池密封胶,固化剂中各原材料的比例不当及固化剂的原生产工艺下,就容易产生上述问题。
随着蓄电池市场需求的逐年上升,对废旧电池的处理与蓄电池的维修越来越受到重视,而蓄电池维修的关键是即要打开密封盖又不能损坏蓄电池外壳,现有的一些密封胶如果是粘接强度高的,在打开密封盖时由于密封胶难于剥离会损坏蓄电池外壳,而易于剥离的粘接强度高均比较低,如何暨保证良好的粘接强度又在打开密封盖时不损坏蓄电池外壳是急待解决的一个难题。
发明内容
本发明的目的是提供一种具有良好的高弹性,耐热性,耐水性,导热性,粘接性,无污染的一种基于乙基酯和甘油酯的高弹性蓄电池密封胶及制作方法,解决蓄电池密封胶的使用需求问题。
为了达到上述目的,本发明提供如下技术方案:
一种基于乙基酯和甘油酯的高弹性蓄电池密封胶,其特征在于:包括A组分和B组分;所述A组分由甲基丙烯酸二甲胺基乙基酯,溶剂,二苯基聚二甲基硅氧烷,纳米碳化硅,补强性填料,抗氧剂,SBS树脂组成;B组分由甲基丙烯酸缩水甘油酯,丁晴橡胶,氢化蓖麻油衍生物,三亚乙基二胺,BYK-065,增粘剂组成;其中所述A组分中,包括:50-70份的甲基丙烯酸二甲胺基乙基酯,15-35份的溶剂,2-15份的二苯基聚二甲基硅氧烷,10-15份的纳米碳化硅,5-15份的补强性填料,5-20份的抗氧剂,25-35份的SBS树脂组成;所述B组分中,包括:60-80份的甲基丙烯酸缩水甘油酯,30-35份的丁晴橡胶,5-15份的氢化蓖麻油衍生物,3-15份的三亚乙基二胺,10-25份的BYK-065,10-15份的增粘剂。
所述A组分中,甲基丙烯酸二甲胺基乙基酯的平均分子量为8000-10000,所述B组分中,甲基丙烯酸缩水甘油酯的平均分子量为10000-14000。
所述A组分中,包括:60份的甲基丙烯酸二甲胺基乙基酯,25份的溶剂,10份的二苯基聚二甲基硅氧烷,12份的纳米碳化硅,10份的补强性填料,12份的抗氧剂,30份的SBS树脂组成;所述B组分中,包括:70份的甲基丙烯酸缩水甘油酯,32份的丁晴橡胶,10份的氢化蓖麻油衍生物,10份的三亚乙基二胺,18份的BYK-065,12份的增粘剂。
所述溶剂为丙酮、三氯甲烷、二氯乙烷、尼龙酸二甲酯、乙酸乙酯、甲苯或二甲苯中的一种或几种的混合;补强性填料为气相法白炭黑、沉淀法白炭黑和表面处理白炭黑中的一种或几种的混合;抗氧剂为IrgastabPUR68、抗氧剂1010和Irganox5057中的一种或几种的混合;增粘剂为钛酸异丙酯、钛酸丁酯、r-氨基丙基三乙氧基硅烷,1、2-环氧乙氧基三甲氧基硅烷、碳酸酯的乙酰乙酸乙酯螯合物中的一种或几种的混合。
具体步骤为:
A组分包括步骤:在密闭反应釜中,加入上述重量份数比的甲基丙烯酸二甲胺基乙基酯,溶剂,二苯基聚二甲基硅氧烷,SBS树脂,搅拌升温,温度控制在80℃~110℃,开启真空泵抽负压,压力控制在-0.1MPa以下;然后降温到65℃以下,通入干燥氮气解除真空,加入上述重量份数比纳米碳化硅,补强性填料,抗氧剂,温度控制在65~75℃,混合均匀,即得A组分密封胶。
B组分包括步骤:在密闭反应釜中,加入上述重量份数比的甲基丙烯酸缩水甘油酯,丁晴橡胶,氢化蓖麻油衍生物,搅拌升温,温度控制在80℃~110℃,开启真空泵抽负压,压力控制在-0.1MPa以下;然后降温到65℃以下,通入干燥氮气解除真空,加入上述重量份数比的三亚乙基二胺,BYK-065,增粘剂,温度控制在65~75℃,混合均匀,即得B组分密封胶。
本发明的有益效果:本发明相较于一般的其他胶黏剂具有良好的高弹性,耐热性,耐水性,导热性,粘接性,无污染等优点,能够在使用过程中良好的粘结,并且密封效果好,内部空气少等效果。
