Abstract
本发明公开了一种水性醇酸树脂的制备方法及其应用,水性醇酸树脂由适量的蓖麻油、多元醇、二元酸和/或酸酐、苯甲酸、松香以及酯化催化剂和带水剂等混合物反应得到;得到的水性醇酸树脂与氨基树脂、流平剂、消泡剂、附着力促进剂及催化剂等复配成绿色环保,耐水性、耐热性及机械性能优异的水性绝缘漆,特别适用于H级以下中小型电机、变压器的浸渍绝缘处理。
Description
技术领域
本发明涉及一种水性醇酸树脂的制备方法及其在水性浸渍绝缘漆中的应用;属于制漆技术领域。
背景技术
传统的浸渍绝缘漆一般以甲苯、二甲苯、苯乙烯、溶剂油等易燃易爆、有毒有害溶剂作稀释剂。这些有机溶剂在生产、施工和干燥过程中,直接排入大气,不仅造成环境污染,还对人体健康产生很大危害。据统计,每年由此排放到大气中的有机溶剂就达数万吨,造成极大的资源浪费,此外,溶剂型绝缘漆在使用和储存过程中还存在安全隐患。
水性浸渍绝缘漆采用水作溶剂,相对于传统溶剂型绝缘漆能极大地减少VOC的排放,有效降低了对环境的影响,降低职业病发生的潜在机率,以及减少火灾风险和储存隐患等优势。但目前水性绝缘漆存在以下几个缺点:1)耐水解性差,特别是水性醇酸类水性绝缘漆,漆加水后容易水解变混,甚至是乳白色,造成储存稳定性差;2)固化后机械强度不高,耐热性差;3)吸水率高,从而使其电绝缘性能差;4)在施工过程中容易出现漆瘤漆泡,表面效果差,虽降低固含能有效解决漆瘤漆泡等问题,但线圈的机械强度下降明显。
发明内容
针对现有的水性浸渍绝缘漆存在的缺陷,本发明的目的是要在于提供一种操作简单、高效、低成本的制备性能优异的水性醇酸树脂的方法。
本发明的另一个目的是在于提供所述的水性醇酸树脂的应用,水性醇酸树脂用于制备绿色环保,耐水性、耐热性及机械性能优异的水性浸渍绝缘漆。
为了实现上述技术目的,本发明提供了一种水性醇酸树脂的制备方法,该方法是将20~40份蓖麻油、20~40份多元醇、20~40份二元酸和/或酸酐、小于或等于9份苯甲酸、小于或等于9份松香,以及酯化催化剂和带水剂加入反应釜中,升温至165~185℃反应1.5~2.5h后,以10~15℃/h速率继续升温至195~215℃反应,待反应体系澄清后,进一步升温至210~220℃反应,直至体系的酸值为7~15mgKOH/g时,降温至150~180℃,并加入4~10份偏苯三酸酐反应,当体系酸值为25~45mgKOH/g时,终止反应,即得。
优选的方案,多元醇为三羟甲基丙烷、三羟甲基乙烷、丙三醇、三羟乙基异氰尿酸酯(赛克)中的至少一种。
优选的方案,二元酸为间苯二酸和/或对苯二酸。
优选的方案,酸酐为苯酐和/或顺酐。
优选的方案,酯化催化剂加入量为0.05~0.1份。
优选的方案,酯化催化剂为PC4100和/或PC4200(均可购于南京鼎晨科技发展有限公司)。
优选的方案,带水剂加入量为2~5份。
优选的方案,带水剂为甲基环己烷。
本发明还提供了所述方法制备的水性醇酸树脂的应用,将所述的水性醇酸树脂应用于制备水性绝缘漆。
优选的方案,水性醇酸树脂通过助溶剂稀释至固含量为70~85%,同时采用有机胺调节pH值至7.5~8.5,配成水性醇酸树脂溶液后,用于水性绝缘漆配方。

(2)由制备的水性醇酸树脂溶液应用于制备水性绝缘漆,将以下组分按质量份计量,直接混合均匀,即得水性绝缘漆:水性醇酸树脂70~100份;氨基树脂15~30份;流平剂0.1~0.5份;消泡剂0.1~0.5份;附着力促进剂0.5~2份;催化剂0.1~0.5份。
本发明的水性绝缘漆适用于H级以下中小型电机、变压器的浸渍绝缘处理。
相对现有技术,本发明的技术方案带来的优点及效果:
(1)本发明的水性醇酸树脂的制备方法简单、高效、成本低,满足工业化生产要求。特别是酯化催化剂的加入,反应时间相对未增加酯化催化剂时至少缩短了一半以上,大大提高了反应效率,降低了生产成本。
(2)本发明的水性醇酸树脂制备的水性绝缘漆具有优异的性能:耐水解稳定性和耐热性好,表干速率快,且在常温及高温(135℃、155℃)下的粘结强度高,成膜后机械性能好,特别适用于H级以下中小型电机、变压器的浸渍绝缘处理。
(3)本发明的水性绝缘漆经济环保,使用时可按原漆兑水2.5~4.5倍使用,兑4倍水后仍能得到较强的机械强度(常态下螺旋线圈法测得数据>100N);使用时VOC可降低至30g/L,因此在实际应用中可大幅度降低使用成本和减少VOC排放。
