耐磨型水性醇酸树脂的研究进展

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的重点，提高醇酸树脂涂层的耐磨性能至关重要。本文在查阅大量文献的基础上，从水性醇酸树脂的合成方法、影响水性醇酸树脂耐磨性能的因素及水性醇酸树脂的耐磨改性方面进行了综述，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。本文对耐磨型水性醇酸树脂今后的发展趋势进行了展望，以期为相关工作者提供借鉴与指导，笔者分析，今后关于耐磨型醇酸树脂的进展主要集中在生物原料的发现、新材料的应用、醇酸树脂的适用范围等方向。

Research progress of abrasion resistance waterborne alkyd resins

Alkyd resin has many advantages, such as fullness, brightness, good adhesion, biodegradability and so on. It is widely used in vehicle, ship, paint and coating industries. However, the durability of alkyd resin coating is poor, and it is vulnerable to external friction stress in the process of use, which makes the protective effect of the coating ineffective. Therefore, enhance the mechanical properties of alkyd resin coating so that it is not easy to be damaged in the process of use is still the focus of attention. It is very important to improve the wear resistance of alkyd resin coating. On the basis of consulting a large number of literatures, this paper summarizes the synthesis methods of waterborne alkyd resin, the factors affecting the wear resistance of waterborne alkyd resin and the abrasion resistance modification of waterborne alkyd resin. At present, the main methods to improve the abrasion resistance of alkyd resin coating are to improve the synthesis process and modify the alkyd resin with functional materials, and improve the properties of alkyd resin from the aspects of coating strength, hardness and toughness. In this paper, the development trend of abrasion resistance waterborne alkyd resin in the future is prospected in order to provide reference and guidance for relevant workers. The author analyzes that the progress of abrasion resistance alkyd resin in the future mainly focuses on the discovery of biological raw materials, the application of new materials, the application scope of alkyd resin and so on.
