摘　　要：结合大型制冷压缩机组设备涂装特点,介绍了一种水性双组分防腐涂料。探讨了主要成膜物、潜伏型固化促进剂、防锈颜料、紫外光吸收剂、触变剂和增稠剂对涂料性能的影响。结果表明:当甲组分选用水性环氧树脂E-pos1025,乙组分选用胺类固化剂B和C,甲、乙组分配比为6∶1,配合0.3%低温潜伏型固化促进剂,以及防锈颜料体系ZMP+CH-6和紫外光吸收剂Light 951时,该水性双组分涂料能够在45℃×30 min烘烤条件下快速固化,漆膜初期耐水性能48 h、耐腐蚀性能720 h、耐候性能200 h;同时配套触变剂972+SD-1和增稠剂3060,能够适用于高压无气双组分自动调配喷涂系统的施工,可实现厚涂150μm不流挂。According to the coating characteristics of large refrigeration compressor equipment,a waterborne two-component anticorrosive coating was introduced. The influence of the main film-forming agents,latent accelerators,antirust pigments,UV absorbers,thixotropic agents and thickening agents on the coating film properties were discussed. The results showed that,when the water-based epoxy E-pos1025 was used as component A,amine curing agents b and c were used as component B,and the equivalent ratio of A and B was 0. 9∶1,with 0. 3% low-temperature latent curing accelerator,rust resistant pigment system of ZMP CH-6 and ultraviolet light absorber of Light951,the two-component waterborne coating could be quickly cured in 30 min at low temperature of 45 ℃. The coating had early water resistance of 48 h,corrosion resistance of 720 h and weather resistance of 120 h,and the coating could be used in high-pressure airless 2K automatic dispensing spraying system to achieve coating thickness of 150 μm without sagging by adding thixotropic agent of 972+SD-1 and thickening agent of 3060.
