Description

一种耐热等级高的变压器用绝缘纸
技术领域
本发明涉及变压器技术领域，尤其涉及一种耐热等级高的变压器用绝缘纸。
背景技术
近年来，随着我国电力、电气、电子、家电和通讯等行业的快速发展，人们对变压器的要求越来越高。纤维素绝缘纸是油浸式电力变压器中应用最广泛的内绝缘材料之一，由于运行期间无法更换，其机械及绝缘性能的好坏直接决定着变压器的使用寿命。实际变压器中，绝缘纸长期受到高强度电场应力的作用，一旦发生击穿将导致变压器故障。如能提升绝缘纸的电气性能，便可节省绝缘纸的使用量，延长绝缘纸的工作寿命，减小变压器油隙的宽度，进而限制变压器的体积和铁芯损耗，因此，开展绝缘纸的改性研究意义重大。云母是电气电子行业中不可缺少的绝缘材料。目前，虽然世界上已出现很多新型材料，但其中还没有一种绝缘材料能够完全取代云母。利用云母来改性绝缘纸可以得到性能更加优异的绝缘纸，但是目前国内外对于这方面的研究很少。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种耐热等级高的变压器用绝缘纸。
本发明是通过以下技术方案实现的：
一种耐热等级高的变压器用绝缘纸，由以下重量份的原料制备制成：硅烷偶联剂kh5500.6-0.7、云母6-8、甘氨酸1-1.5、硅烷偶联剂kh5700.3-0.4、乳化剂OP-100.1-0.2、十二烷基磺酸钠0.2-0.3、E44环氧树脂2-3、硬脂酸铈0.3-0.5、浆板500-550、果胶纤维3.4-4、防老剂MB0.3-0.4、纳米氮化硼1.2-1.6、钨酸铅0.3-0.5、去离子水适量。
所述一种耐热等级高的变压器用绝缘纸，由以下具体步骤制备制成：
（1）将硅烷偶联剂kh550加入到乙醇与水质量比为1:1的溶液中，水浴加热至35°C，滴加乙二酸调节PH值为4，水解1-1.5h，将云母片浸渍到75%的乙醇中搅拌浸泡1-2h，然后超声洗涤10-15min，再用去离子水浸泡0.5h，最后置于烘箱中于110°C下干燥2h，研磨备用；
（2）将上述制备的云母加到硅烷偶联剂kh550的水解液中，水浴温度控制在60-65°C，然后加入纳米氮化硼和果胶纤维超声搅拌30-45min，过滤，用去离子水洗涤数次，之后在恒温鼓风干燥箱中于90°C下干燥2-3h备用；
（3）将甘氨酸用13倍量的水溶解后和硅烷偶联剂kh570、乳化剂OP-10、十二烷基磺酸钠和E44环氧树脂加到烧瓶中，控制水浴温度在80-85°C下缓慢搅拌3h，再加入防老剂MB和钨酸铅继续搅拌10-15min，然后加入氢氧化钠溶液调节PH值呈中性，再用高剪切分散乳化机将其乳化，得到稳定的改性水性环氧树脂乳液；
（4）将步骤（2）制备的改性云母、步骤（3）制备的改性水性环氧树脂乳液和硬脂酸铈混合，再加入适量的去离子水稀释成质量浓度在0.5-0.6%的浆料，将浆板浸泡后进行打浆，打浆度为40-45°SR时停止打浆，然后将浆料放入纤维解离器中，加入去离子水使浆料的浓度在2-2.5%进行解离，得到纸浆悬浊液备用；
（5）将纸浆悬浊液和云母浆料混合，用电力搅拌棒强力搅拌10min，然后继续解离15min，之后进行抄造、烘干即可得到绝缘纸。
本发明的优点是：本发明采用硅烷偶联剂kh550对云母进行表面改性，增强云母表面的侨联作用，改善和改性的水性环氧树脂乳液的相容性，提高了对云母表面的附着力，和纤维素纸浆混合能够大大提高其结合力与分散均匀性，增强了绝缘纸的拉伸强度、介电强度、电气性能和耐热性能等作用，添加的纳米氮化硼和果胶纤维能够提高绝缘纸的耐热、耐磨、高强等方面的作用，添加的防老剂MB和钨酸铅能够提高绝缘纸的耐老化性、稳定性的作用，本发明的制备方法简单，原料广泛，生产成本低，耐热等级高，稳定性好，可大规模生产，值得推广。
