Abstract

Novel organic-inorganic hybrid coating materials were developed using amino silanes and acetoacetylated soybean oil. The acetoacetylated soybean oil was prepared from soybean oil (a renewable resource) using a solvent-free method involving a thiol-ene and transesterification reactions, and the chemical structure was characterized by nuclear magnetic resonance (NMR), gel permeation chromatography (GPC), Fourier-transform infrared (FTIR) spectroscopy, and viscosity analyses. On the basis of the acetoacetylated soybean oil, several organic-inorganic hybrid coating materials were prepared using different amino silanes by a catalyst-free method involving one-step comprising two reactions (an amine-acetoacetate reaction and an sol-gel technique), and their crosslinked structures were determined from their FT-IR and solid-state Si NMR spectra. The resulting coating materials have good mechanical/chemical performance. This method for preparing renewable organic-inorganic hybrid coating materials may have wide uses because plant oils contain many unsaturated C[double bond, length as m-dash]C bonds and easy access to acetoacetate functional groups.

摘要

利用氨基硅烷和乙酰乙酰化大豆油开发了新型有机-无机杂化涂料。乙酰乙酰化大豆油由大豆油（一种可再生资源）通过无溶剂方法制备，该方法涉及硫醇-烯反应和酯交换反应，其化学结构通过核磁共振（NMR）、凝胶渗透色谱（GPC）、傅里叶变换红外（FTIR）光谱和粘度分析进行表征。基于乙酰乙酰化大豆油，通过无催化剂方法使用不同的氨基硅烷制备了几种有机-无机杂化涂料，该方法包括一步包含两个反应（胺-乙酰乙酸酯反应和溶胶-凝胶技术），并根据它们的FT-IR和固态Si NMR光谱确定其交联结构。所得涂料具有良好的机械/化学性能。这种制备可再生有机-无机杂化涂料的方法可能有广泛用途，因为植物油含有许多不饱和C=C键且易于引入乙酰乙酸酯官能团。
