摘　　要：定子线棒是电机生产中的关键部件。用于定子线棒表面涂料固化的传统工艺周期长、效率低、能耗高。红外辐射固化是一种有可能克服这些问题的方法。本研究调查了三种油漆(低电阻、高电阻和红瓷漆)在红外辐射下在定子线棒表面的固化行为。涂料样品以环氧玻璃布板为基底材料,以碳化硅红外辐射板为红外辐射源制备而成。固化后的涂料通过红外光谱和扫描电子显微镜进行了表征。测量了每个样品的固化程度和电气性能,并与使用传统固化工艺获得的结果进行了比较。结果表明,三种涂料经红外辐射固化后的固化度分别比传统固化工艺下的固化度高8.98%、10.33%和10.40%,并能在2 min内达到表面干燥效果。涂料的电气性能和表面形态均符合标准性能要求。通过红外线辐射固化的涂料具有良好的电气性能。因此,该研究证明了红外辐射固化方法的高效性和实用性,以及其广泛的潜在适用性。Stator bars are crucial components in motor production.The traditional process used for curing the surface paint of stator bars has a long cycle,low efficiency,and high energy consumption.Infrared radiation curing is a method that can potentially overcome these issues.This study investigated the curing behaviors of three types of paints(low-resistance,high-resistance,and red enamel paints)on the surfaces of stator bars under infrared radiation.The paint samples were prepared using an epoxy glass cloth plate as the substrate material and a silicon carbide infrared radiation plate as the infrared radiation source.The cured paint was characterized via infrared spectroscopy and scanning electron microscopy.The degree of curing and the electrical properties of each sample were measured and compared with those obtained using the traditional curing process.The results indicated that the degree of curing of the three types of paints after curing by infrared radiation was higher than that under the traditional curing process by 8.98%,10.33%,and 10.40%,respectively,and that the surface drying effect could be achieved in 2 min.The electrical properties and surface morphologies of the paints were shown to satisfy the standard performance requirements.The paints cured by infrared radiation exhibited good electrical properties.The study thus demonstrated the high efficiency and practicability of the infrared radiation curing method,as well as its wide potential applicability.
