【摘要】 本文通过对硅酸钾、硅溶胶、烷氧基硅烷性能的研究，反应温度的影响，确定了以硅酸钾、硅溶胶、烷氧基硅烷及水为原料，在一定温度范围内通过正交实验合成了高模数硅酸钾溶液作为片状无机富锌涂料用基料，与适量锌粉混合后配制成片状无机富锌涂料。通过机械性能检测、浸泡试验及盐雾实验表明片状无机富锌涂料性能优良。经过对市售球状无机富锌涂料进行同样的性能测试，与片状无机富锌涂料进行对比，表明片状无机富锌涂料性能比市售球状无机富锌涂料有所提高。无机富锌涂料通常作为底漆使用，上面需涂中间漆及面漆，以提高耐蚀性。实验选用环氧云铁作为中间漆，氯化橡胶作为面漆与片状无机富锌涂料复合，配制成底／中／面三涂层体系及底／面两涂层体系进行性能测试，同时将市售球状无机富锌涂料与中间漆及面漆配成三涂层体系及两涂层体系浸泡在3.5％NaCl溶液中进行交流阻抗测试，结果表明片状无机富锌涂料与中间漆及面漆的配套性良好。更多还原

【Abstract】 Based on the study of potassium silicate, silica sol, Trialkoxysilane performance, the reaction temperature, determined potassium silicate. sol, alkoxy silane and water as raw material, in a certain temperature range through orthogonal experimental, synthesis of a high modulus potassium silicate solutions as inorganic flake zinc-rich coating with the base material. With the proper preparation flake zinc mixed into inorganic flake zinc-rich coating. Through mechanical properties testing, salt spray and immersion test results show inorganic flake zinc-rich coating has good performance.Through the commercial inorganic spherical zinc-rich coating for the same performance test, comparison with inorganic flake zinc-rich coating, showed inorganic flake zinc-rich coating has better properties than commercial inorganic spherical zinc-rich coating.Inorganic zinc-rich coating is usually used as primer, above it needs to cover middle section and top section, to improve corrosion resistance. Experimental use MIO epoxy primer as an intermediary coating, chlorinated rubber as top section as composite coating of inorganic flake zinc-rich coating. And prepared the primer /intermediary /top tir-layer system and primer /top double layer system performance testing, while use commercial inorganic spherical zinc-rich coating, middle section and top section prepared double layer system and tir-layer system and immersion into 3.5% NaCl solution for electrochemical impedance spectroscopy test (EIS). The results showed inorganic flake zinc-rich coating matched with the middle section and the top section well.更多还原
