摘　　要：为了开发出具有良好清洗效果的电子设备带电清洗剂,对比分析了二元共沸混合物、三元共沸混合物的各项物理性能、溶解性能和对污垢的清洗效果。结果表明,虽然4种二元共沸混合物nPB/异丙醇、nPB/正己烷、nPB/环己烷和nPB/乙酸乙酯以及2种三元共沸混合物nPB/正丁醇/正己烷和nPB/正己烷/无水乙醇,在外观、稳定性和腐蚀性等方面具有相似的属性,但是在相对密度、黏度、残留量、挥发速度、绝缘电阻和击穿电压上有明显差异;二元共沸混合物和三元共沸混合物清洗剂的挥发速度随着时间都呈线性变化,表明挥发性质都较为稳定。三元共沸混合物清洗剂的溶解性能优于二元共沸混合物,nPB/正丁醇/正己烷和nPB/正己烷/无水乙醇的污垢去除率分别为96.7%和98.3%,nPB/正己烷/无水乙醇去除污垢的效果要优于nPB/正丁醇/正己烷,且都高于二元共沸混合物清洗剂和单独nPB清洗剂。In order to develop electric cleaning agents for electronic devices with good cleaning effects,the physical property,solubility and dirt cleaning Effect of binary azeotropic mixture and ternary azeotropic mixture were compared and analyzed.The results showed that,although the four binary azeotropic mixtures(nPB/isopropanol,nPB/n-hexane,nPB/cyclohexane and nPB/ethyl acetate)and the two ternary azeotropic mixtures(nPB/n-butanol/n-hexane and nPB/n-hexane/anhydrous ethanol)had similar properties in appearance,stability and corrosivity,there were significant diff erences in relative density,viscosity,residue,volatilization rate,insulation resistance and breakdown voltage.The volatilization rate of binary azeotropic mixture and ternary azeotropic mixture detergents changes linearly with time,indicating that the volatilization properties are relatively stable.The solubility of ternary azeotropic mixture cleaning agent is better than that of binary azeotropic mixture.The fouling removal rates of nPB/n-butanol/n-hexane and nPB/n-hexane/anhydrous ethanol are 96.7%and 98.3%respectively.The fouling removal Effect of nPB/n-hexane/anhydrous ethanol is better than that of nPB/n-butanol/n-hexane,and both are higher than that of binary azeotropic mixture cleaning agent and nPB cleaning agent.
