摘要

在本研究中，我们优化了 100-160 nm 单分散 SiO2 纳米粒子的制备方法，并通过掺杂研究了它们对水基丙烯酸-氨基清漆物理性质的影响。首先，我们采用基于半批次溶胶-凝胶法的非固定点进料技术，提高了小尺寸单分散 SiO2 纳米粒子的产量。为了降低生产成本和有机物污染，我们在单一反应体系中评估了一些溶液参数，包括正硅酸四乙酯（TEOS）、乙醇（ETOH）和氨水。我们发现，通过添加 1.2 % 的 SiO2 纳米粒子，丙烯酸-氨基清漆的光泽度、透明度、硬度、附着力和其他物理性质都得到了成功提高。

EFFICIENT PRODUCTION OF SMALL-SIZED SiO2 NANOPARTICLES AND THEIR APPLICATION IN A WATERBORNE ACRYLIC-AMINO VARNISH

In this study, we optimized the preparation of 100–160 nm monodispersed SiO2 nanoparticles and, through doping, investigated their effects on the physical properties of a water-based acrylic-amino varnish. First, using a non-fixed point feeding technique based on the half-batch sol-gel method, we enhanced the yield of small-sized monodispersed SiO2 nanoparticles. To reduce the cost of production and organic-matter pollution, we assessed certain solution parameters including tetraethyl orthosilicate (TEOS), ethanol (ETOH) and ammonia in a single-reaction system. We found that the gloss, clarity, hardness, adhesion, and other physical properties of the acrylic-amino varnish were successfully enhanced through an addition of 1.2 % SiO2 nanoparticles.
