摘要:醇酸树脂具有丰满、光亮、附着力好、可生物降解等诸多优点,广泛应用于车辆船舶、油漆涂料等行业。
但醇酸树脂涂层耐久性较差,在使用过程中易受外界摩擦应力使涂层的保护作用失效。因此,如何对醇酸树脂
涂层的机械性能进行增强,使其在使用过程中不易遭到破坏依然是目前关注重点,提高醇酸树脂涂层的耐磨性
能至关重要。首先,介绍了水性醇酸树脂的合成方法;然后,总结了合成工艺对水性醇酸树脂耐磨性能的影响;
接着,综述了功能材料改性对水性醇酸树脂耐磨性能的影响。指出目前提升醇酸树脂涂层耐磨性能的主要方法
是改进合成工艺以及利用功能材料对醇酸树脂进行改性,从涂层强度、硬度、韧性等方面对醇酸树脂的性能进
行提升。最后,对耐磨型水性醇酸树脂今后的发展趋势进行了展望。

Abstract: The many advantages of alkyd resin, such as high-fullness, high-distinctness, good adhesion,
biodegradability, has led to its wide use in industries of vehicle and ship, paint and coating etc.
However, the alkyd resin-based coating is vulnerable to external friction stress in the process of use due to
its poor durability, which makes the protective effect of the coating not lasting. Therefore, the current
research is mainly focused on the mechanical property enhancement of alkyd resin coating, especially the
wear resistance improvement, to avoid easy damage in the process of use. Herein, the synthesis methods of
waterborne alkyd resin were firstly introduced, followed by summarization of the influence of synthesis
conditions as well as functional material modification on the wear-resistance property of waterborne alkyd
resin. It was pointed out that wear resistance improvement should be started from enhancement in the
aspects of strength, hardness, toughness via synthesis process regulation and functional material
modification. Finally, the development trend of wear-resistant waterborne alkyd resin was prospected.
