          摘要:

          將蓖麻油(CO)作為交聯劑,引入以季戊四醇三丙烯酸酯(PETA)封端的水性聚氨酯(WPU)中,通過紫外光照使雙鍵之間發生交聯,以構筑一種雙重交聯體系。制備出了不同CO含量的CWPU涂層,探究CO的含量對CWPU涂層的各種性能影響。測試結果表明:當CO含量為4 %時,薄膜的24 h吸水率為4.5 %,表面硬度為2 H等級,對Q235鋼板基底的附著力為0等級。后續又通過極化曲線測試及阻抗譜測試等對其防腐蝕性能做了測試分析,結果表明4 % CO含量的CWPU涂層對Q235鋼板基底的保護效率可達99.05 %。

          Abstract:

          Castor oil (CO) was introduced as a cross-linking agent into a water-based polyurethane (WPU) capped with pentaerythritol triacrylate (PETA), and the double bonds were cross-linked by ultraviolet light to construct a dual cross-linking system. CWPU coatings with different CO contents were prepared, and the effects of CO content on various properties of CWPU coatings were explored. The test results show that when the CO content is 4 %, the 24 h water absorption of the film is 4.5 %, the surface hardness is 2 H, and the adhesion to the Q235 steel plate substrate is 0. Subsequently, the anti-corrosion performance was tested and analyzed by polarization curve test and impedance spectrum test. The results showed that the protection efficiency of the CWPU coating with 4 % CO content on the Q235 steel plate substrate could reach 99.05 %.
