摘要/Abstract

摘要： 利用埃洛石纳米管(HNTs)对防霉乳液进行改性,提升了涂料的综合性能,实现了有机碘化物(IPBC)在埃洛石纳米管上的吸附,利用热重分析(TGA)、傅里叶红外分析(FT-IR)和环境扫描电镜(ESEM)对样品进行表征。使用改性前后的乳液涂料对竹材进行处理,利用接触角测定仪测量了处理前后试材的疏水性能,并研究了处理前后竹材防霉性能的差异。结果表明:埃洛石纳米管能有效吸附高达63.78%的防霉剂,改善涂料的微观形貌; 能在竹材表面形成致密的保护层,使竹材的疏水性提高26.46%; 并且改性后的防霉乳液对霉菌、蓝变菌的防治效力达100%。这种改性乳液涂料在竹材上具有良好的防水、防霉效果,具有处理方式简便、环保低毒的优点。

Abstract: When mildew-proof emulsion coating was modified with halloysite nanotubes(HNTs), the organic iodide(IPBC)that was an effective mildew proof agent in coating, can be adsorbed by halloysite nanotubes. Using the thermal gravimetric analysis(TGA), Fourier transform infrared(FTIR)spectroscopy and environment scanning electron microscopy(ESEM), it was found that the heat-resistance, hydrophobicity and mildew-proof properties of the coating were enhanced. The hydrophobicity of the emulsion coating was examined using the contact angle test and the mildew-proof efficiency was compared before and after the modification with halloysite nanotubes. Experiment results showed that the halloysite nanotube had the ability to absorb mildew-proof agent up to 63.78%, leading to a change of the microscopic morphology of the coating. A protective layer of the modified coating existed on the bamboo surface, improving the bamboo hydrophobicity by 26.46%. The modified mildew-proof coating had the mildew preventing efficiency of 100% and was expected to expand its applications in mildew proofing areas.
