摘　　要：利用硅烷偶联剂（KH550）对水性UV固化木器涂料进行改性，并对其力学性能和光学性能进行测试研究，旨在寻找到一种具有较高性能的改性水性UV固化木器涂料。结果表明，当KH550@含量为1．96％-3．23％，干燥时间为40min，紫外灯为3盏时，水性UV固化涂膜的硬度、附着力和抗冲击强度分别达到2H、2级和30kg·cm。KH550的含量对涂膜的光泽度影响不大。The mechanical and optical performance of waterborne UV-curable wood coatings modified by KH550 was measured. The authors aim at developing the modified waterborne UV- curable wood coatings with high performance. The results showed that when the KH550 content was 1.96%-3.23%, the drying time was 40 min, and UV lamp was 3, the hardness, adhesion and impact strength of UV-curable waterborne coatings were 2H, 2 grade, and 30 kg.cm, respectively. The KH550 content had little effect on gloss of the coatings.
