【摘要】：目的對硅烷偶聯(lián)劑KH-550硅烷化改性鋁合金的工藝進行優(yōu)化,在不影響膜層性能的前提下,創(chuàng)新性降低乙醇含量,以滿足工業(yè)化生產(chǎn)中安全、低成本的需求。方法采用單因素變量法,研究硅烷溶液中硅烷和乙醇的濃度、固化溫度及固化時間等因素對硅烷膜耐蝕性的影響,由此確定最佳配方工藝,并分析硅烷膜的表面形貌、成分及疏水性。結(jié)果采用硅烷、去離子水、乙醇體積比為5∶55∶40的硅烷溶液,涂膜后,在180℃下加熱40 min,能得到較完整均勻、耐蝕性較好的硅烷膜,膜層由C,O,Si等元素組成。硅烷濃度對硅烷膜的耐蝕性及表面接觸角影響較大,在最佳工藝下獲得的硅烷膜表面接觸角可達70.2°。結(jié)論硅烷膜對鋁合金基體具有一定的屏障作用,保護基體免受腐蝕。
[Abstract]:Objective to optimize the process of silane coupling agent KH-550 silane modified aluminum alloy, and to reduce the content of ethanol creatively without affecting the performance of the film, so as to meet the safety in industrial production. Methods the effects of the concentration of silane and ethanol in silane solution, curing temperature and curing time on the corrosion resistance of silane film were studied by single factor variable method. The surface morphology, composition and hydrophobicity of silane film were analyzed. Results Silane film was prepared by using silane, deionized water, and silane solution with the volume ratio of ethanol to ethanol at 5:55:40. After heating at 180 鈩，
