Abstract

Ultraviolet (UV) coatings are widely used because of their good performance. However, the self-healing performance of UV coatings can be further improved. Microcapsule technology can be used to solve this problem. To investigate the effects of the compound use of two UV coating microcapsules on coatings of a fiberboard surface, three kinds of UV primer microcapsules (1#, 2#, and 3# microcapsules) with different contents were added to a UV primer, and a UV top coating was prepared with UV top coating microcapsules at a consistent ratio. The UV coating was used to coat the fiberboard surface by way of a two-primer and two-top coating method. The results show that as the content of the UV primer microcapsules was increased, the self-healing rates of all three groups of coatings increased and later decreased. The color difference ΔE of coatings with the content of the UV primer microcapsules at 4.0% and top coating microcapsules at 6.0% was 3.59, the gloss was 1.33 GU, the reflectance was 21.17%, the adhesion grade was 2, the hardness was 2H, the impact resistance grade was 5, the roughness was 1.085 μm, and the self-healing rate was 30.21%. Compared with the self-healing rate of the blank control group, the increase in the self-healing rate was 10.07%, and the improvement rate was 50.00%. The comprehensive performance of the coating was better. The results provide a technical reference for the application of the UV coating microcapsules in the UV coating on fiberboard surfaces. Incorporating the self-healing UV coating microcapsules into the UV coatings and applying the UV coating microcapsules on the fiberboard surfaces supports the microcapsule technology of self-healing UV coatings, lays the foundation for extending the service life of furniture while improving the furniture’s quality, and promotes the sustainable development of the coating industry.

两种 UV 涂层微胶囊的复合使用对纤维板表面涂层的物理化学、光学、机械和自愈合性能的影响

紫外线（UV）涂料因其良好的性能而被广泛使用。然而，紫外线涂料的自愈性能还有待进一步提高。微胶囊技术可用于解决这一问题。为了研究两种 UV 涂层微胶囊复合使用对纤维板表面涂层的影响，在 UV 底漆中加入了三种不同含量的 UV 底漆微胶囊（1#、2# 和 3#微胶囊），并以一致的比例用 UV 面涂层微胶囊制备了 UV 面涂层。UV 涂层采用双底漆和双面涂层的方法涂覆在纤维板表面。结果表明，随着 UV 底涂微胶囊含量的增加，三组涂层的自愈率均有所上升，随后又有所下降。UV 底漆微胶囊含量为 4.0% 和面漆微胶囊含量为 6.0% 的涂料的色差 ΔE 为 3.59，光泽度为 1.33 GU，反射率为 21.17%，附着力为 2 级，硬度为 2H，抗冲击性为 5 级，粗糙度为 1.085 μm，自愈率为 30.21%。与空白对照组的自愈率相比，自愈率提高了 10.07%，改善率为 50.00%。涂层的综合性能更好。该结果为 UV 涂层微胶囊在纤维板表面 UV 涂层中的应用提供了技术参考。在 UV 涂层中加入自修复 UV 涂层微胶囊，并将 UV 涂层微胶囊应用于纤维板表面，支持了自修复 UV 涂层微胶囊技术，为延长家具使用寿命的同时提高家具质量奠定了基础，促进了涂料行业的可持续发展。

期刊介绍： Coatings is an international, peer-reviewed open access journal of coatings and surface engineering. It publishes reviews, research articles, communications and technical notes. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. Full experimental and/or methodical details must be provided. There are, in addition, unique features of this journal: * manuscripts regarding research proposals and research ideas will be particularly welcomed * electronic files or software regarding the full details of the calculation and experimental procedure - if unable to be published in a normal way - can be deposited as supplementary material
