Abstract

本发明涉及包括在合适溶剂中混合的聚硅氮烷和分散在其中的纳米颗粒的涂层组合物、形成涂层组合物的方法、形成涂层的方法和涂层。

Description

涂层组合物、涂层及其形成方法
技术领域
本发明涉及涂层组合物、涂层及其形成方法。
背景技术
聚硅氮烷由于其在耐化学性、更高的耐温性、疏水性和表面硬度方面的优异性能而被广泛使用。聚硅氮烷是热固性树脂并且可以在环境条件下方便地固化。它可以通过使用常规的溶剂承载的涂覆技术例如喷涂、旋涂、擦拭和浸涂施加到表面。固化的聚硅氮烷涂层可以具有1μm-10μm的厚度，并且其经由共价键粘附到表面。由于这些优点，聚硅氮烷已经作为前表面保护涂层出现。存在两种类型的聚硅氮烷：有机全氢聚硅氮烷(PHPS)和有机聚硅氮烷(OPSZ)。对于一般应用，通常使用具有合适组成的PHPS和OPSZ的混合物。
尽管有这些关键优点，薄的聚硅氮烷涂层不能提供电绝缘。此外，类似于任何其他金属或聚合物表面，聚硅氮烷涂覆的表面也受到微生物污染，尤其是公共和规则接触的表面。通常表面或规则或通常接触的表面被所有种类的微生物污染。这种微生物可以在表面上保持存活和活性达几个小时。因此，它是在大流行病期间病毒传播的共同来源。在一定程度上，这种污染聚集到大流行病期间的病毒传播。常见病毒包括流感A/WSN/33(H1N1)、流感B/70555、肠道病毒71/4643(手足口饮食)、Covid-19等。
已知诸如铜和铝的金属是良好的电导体。由这种材料制成的电线和条带通常用作许多电气应用中的电导体和触点，例如发电、电力传输、配电、电信、电子电路、电子器具和设备等。
通常，金属线或条带通过PVC(聚氯乙烯)或橡胶层绝缘。PVC或橡胶层被涂覆到金属线或条带的表面上。对于诸如变压器、感应器、电机、扬声器、硬盘磁头致动器、电磁铁等的电磁应用，铜线采用聚乙烯醇缩甲醛(formvar)、聚氨酯、聚酰胺、聚酯、聚酯-聚酰亚胺、聚酰胺-聚酰亚胺(或酰胺-酰亚胺)和聚酰亚胺薄层进行绝缘(也称为漆包)。对于这些绝缘或漆包线，薄绝缘层通常为约150-200μm厚，并且工作温度通常高达200℃。这是因为聚合物绝缘层可以在高于200℃的温度下熔化。这种温度限制基本上限制了铜线的电负载承载能力，因此限制了电磁装置的性能。
此外，由于金属线或条带的操作环境，涂层必须坚硬以抵抗磨损和撕裂，并且同时必须是柔性的以允许铜线或条带被铺设并安装在装置的紧密间隔的壳体中。
因此，为了增加金属线或条带的电负载承载能力以改善电磁装置的性能，需要能够承受更高的熔化温度(例如，高于200℃)并且能够使金属线或条带电绝缘的涂层。此外，涂层应该是相对硬的但柔性的。此外，优选地，金属丝或金属条的制造成本应该相对较低，以使其能够承受商业上可行的金属丝或金属条。
除了上述之外，开发能够提供电绝缘和上述性能的涂层将是有益的。
优选地，涂层可以是薄的、耐用的并且适用于室内和室外的抗微生物涂层，并且当施加到这些公共表面上时将有助于消除或减少大流行病期间的病毒传播。
