苯骈三氮唑是杂环化合物，与铜及其盐类能形成稳定络合物
苯骈三氮唑是杂环化合物，与铜及其盐类能形成稳定络合物，在铜合金表面生成不溶性且相当牢固的透明保护膜，使铜雕病被抑制并稳定下来，防止水蒸气和空气污染物的侵蚀。用蒸馏水和甲苯、丙酮等有机溶剂，清除铜雕表面泥土油污，然后浸入苯骈三氮唑酒精溶剂中进行渗透，即可形成络合物保护膜。但苯骈三氮唑易受热升华，失去保护作用，所以最后应在铜雕表面涂一层高分子材料，做封护膜。
Benzotriazole is a heterocyclic compound. It can form a stable complex with copper and its salts. It can form an insoluble and quite firm transparent protective film on the surface of copper alloy, which can inhibit and stabilize the copper carving disease and prevent the erosion of water vapor and air pollutants. Using distilled water, toluene, acetone and other organic solvents to remove the dirt and oil on the surface of the copper carving, and then immersed in benzotriazole alcohol solvent for penetration, the complex protective film can be formed. However, benzotriazole is easy to sublimate and lose its protective effect, so a layer of polymer material should be coated on the surface of the copper sculpture to make a sealing film.
