Description

高性能绝缘漆
技术领域
本发明涉及一种高性能绝缘漆，属于绝缘漆技术领域。
背景技术
绝缘漆又叫绝缘涂料，是一种具有优良电绝缘性的涂料。它以高分子聚合物为基础，能在一定的条件下固化成绝缘膜或绝缘整体，具有良好的电性能、热性能、机械性能和化学性能。绝缘漆是电力方面的必备材料，主要用在一些电工设备上，有效的起到给导体绝缘的效果。绝缘漆作为一种日常生产中常用的原料，在大多数电力设备、电缆电线生产中均需用到大量的绝缘漆，绝缘漆的各种性能直接影响其使用效果，如附着力不好，容易在使用过程中脱落，硬度低则导致绝缘膜裂开，不耐高温则导致绝缘漆熔化等，这些现象会导致用电设备漏电，短路，甚至更严重的灾害。工业上，对绝缘漆有以下要求：1、绝缘性能优良；2、附着力好，机械强度高；3、收缩应力小；4、耐热性可以满足变压器的不同要求；5、对户外或特殊环境可以满足其特殊要求，防辐射，防腐蚀，防紫外线等；6、工艺性良好，操作性好，无毒或低毒，干燥时间短等。但现有的绝缘漆还无法完全满足上述要求。
发明目的
本发明的目的在于提供一种综合性能较好的高性能绝缘漆，具有绝缘性好，附着力强，硬度高，耐高温、耐磨损等优良性能。
所述的高性能绝缘漆，由以下重量份的原料组成：双马来酰亚胺树脂30-40份，环氧树脂20-30份，环己酮50-60份，间对甲酚40-50份，十溴二苯醚5-10份，三氧化二锑10-17份，2-苯基-4-甲基咪唑3-8份，丙烯酸树脂3-6份，二甲基氨基乙醇1-3份，纳米二氧化硅5-15份，氧化镁5-10份，邻苯二甲酸二辛脂3-5份，脂肪醇聚氧乙烯醚1-3份，烷基改性有机硅氧烷1-3份，氨基树脂1-3份。
所述的高性能绝缘漆，由以下重量份的原料组成：双马来酰亚胺树脂35份，环氧树脂25份，环己酮55份，间对甲酚45份，十溴二苯醚8份，三氧化二锑15份，2-苯基-4-甲基咪唑5份，丙烯酸树脂5份，二甲基氨基乙醇2份，纳米二氧化硅10份，氧化镁8份，邻苯二甲酸二辛脂4份，脂肪醇聚氧乙烯醚2份，烷基改性有机硅氧烷2份，氨基树脂2份。
与现有技术相比，本发明的有益效果是：
环氧树脂漆附着力强，收缩力小，耐化学品性、防腐性、耐水性、热稳定性和电绝缘性优良，广泛用于建筑、化工、汽车、舰船、电气绝缘等方面。双马来酰亚胺树脂具有优异的耐热性、电绝缘性、透波性、耐辐射、阻燃性，良好的力学性能和尺寸稳定性，成型工艺类似于环氧树脂，有与环氧树脂相近的流动性和可模塑性，可用与环氧树脂相同的一般方法进行加工成型，克服了环氧树脂耐热性相对较低的缺点。本发明采用双马来酰亚胺树脂和环氧树脂配合使用，辅以各种涂料助剂，所生产的绝缘漆具有优异的绝缘性能，附着力好，粘接能力突出，漆膜硬度高，丰满度好，漆膜表面均匀、致密、光滑，无微孔，而且具有良好的机械性能，硬度高，耐磨损，耐刮伤等性能，本发明综合性能较高，广泛适用于各种电气设备。
