制备了氨基改性的SBA-15介孔分子筛，以氨基改性SBA-15介孔分子筛为载体分别对溶菌酶和脂肪酶进行固定化，并优化固定化条件。通过正交试验确定氨基改性SBA-15介孔分子筛共固定化双酶的最佳条件。将该共固定化双酶添加到环氧树脂中制备复合涂层。采用极化曲线法和电化学阻抗法分析该复合涂层的耐蚀性。结果表明：共固定化双酶的最佳条件为溶菌酶质量浓度0.2 g/L、溶菌酶固定化时间6 h、脂肪酶质量浓度为0.8 g/L，脂肪酶固定化时间10 h；复合涂层中添加1.5%（质量分数）的共固定化双酶时，其耐腐蚀性最佳，缓蚀率可达96.61%。

Amino-modified SBA-15 mesoporous molecular sieves were prepared first. The amino-modified SBA-15 mesoporous molecular sieve was used as a carrier to immobilize lysozyme and lipase respectively, and the immobilization conditions were optimized. The optimal conditions for co-immobilization of double enzymes on amino-modified SBA-15 mesoporous molecular sieve were determined by orthogonal test. The co-immobilized double enzymes were added to epoxy resin to prepare a composite coating. Polarization curve method and electrochemical impedance method were used to analyze the corrosion resistance of the composite coating. The results show that the optimal conditions of co-immobilization of double enzymes were as following: the mass fraction of lysozyme was 0.2 g/L and the time of immobilizing lysozyme was 6 h, the mass fraction of lipase was 0.8 g/L and the time of immobilizing lipase was 10 h. The composite coating added with 1.5% (mass fraction) immobilized double enzymes had the best corrosion resistance, its corrosion inhibition efficiency hit 96.61%.
