Abstract
The invention relates to a composite copper surface corrosion inhibitor for a copper zipper and a preparation method of the composite copper surface corrosion inhibitor. The composite copper surface corrosion inhibitor is prepared from benzotriazole (BTA), 8-quinolinol (HQ), an additive and water. Benzotriazole (BTA) and 8-quinolinol (HQ) have a synergistic corrosion inhibition effect for copper corrosion in an electrolyte solution, and the mechanism is as follows: 8-quinolinol (HQ) can be coordinated with Cu<2+> generated by corrosion to form a [Cu(II)-OC9H6C] complexing film which is used as the additive at a defect of a [Cu(I)-BTA] protective film to form a more compact protective film on the surface of metal copper, so that the protective capability for metal is enhanced. A copper surface treated by the composite copper surface corrosion inhibitor is stronger in corrosion inhibition capability than the copper surface treated by the traditional benzotriazole (BTA) treating fluid; proved by related salt spray testes, the copper surface treated by using the composite copper surface corrosion inhibitor is not found to be corroded.
Description
Technical field
The present invention relates to complex copper surface inhibiter and preparation method thereof for a kind of copper slide fastener.
Background technology
Benzotriazole (BTA) aqueous solution is industrial a kind of traditional widely used copper inhibitor, the copper surface inhibition being equally also widely used in copper slide fastener production process is processed, and the quality proportioning while using in the actual production of copper slide fastener is: benzotriazole (BTA) ︰ water=(1.0 ~ 2.0) ︰ 1000.Its corrosion inhibition is mainly from BTA and univalent copper ion Cu
+at copper surface complexation, form [Cu (I) – BTA] complex compound protective membrane.Because benzotriazole (BTA) toxicity is large and environmental pollution is serious, therefore, it is inexorable trend that new green inhibiter better by corrosion mitigating effect and environmentally safe replaces.
Summary of the invention
The object of the invention is to the improvement to the copper inhibitor of tradition use, complex copper surface inhibiter for a kind of copper slide fastener is provided.Be intended to obtain better corrosion mitigating effect and reduce the pollution to environment.
The present invention, complex copper surface inhibiter for described copper slide fastener, benzotriazole (BTA), oxine (HQ), additive and water, consist of, its quality proportioning is: ((HQ) ︰ Tian Jia Ji ︰ is Wu Shui Yi Chun ︰ water=(0.5 ~ 1.0) ︰ (0.8 ~ 1.3) ︰ (0.1 ~ 0.3) ︰ (1.0 ~ 5.0) ︰ 1000 for BTA) ︰ oxine for benzotriazole.
The present invention, described benzotriazole (BTA) is water-soluble benzotriazole (BTA).
The present invention, described additive is that 30wt% sodium lauryl sulphate (SDS) aqueous solution and concentration are the 50% sulfuric acid solution that 1 ︰ (0.1 ~ 0.3) mixes by volume.
The present invention, the preparation method of complex copper surface inhibiter for described copper slide fastener, comprises the steps:
(1) by quality proportioning, be that ((((1.0 ~ 5.0) ︰ 1000 take respectively required benzotriazole (BTA), oxine (HQ), additive, dehydrated alcohol and water to 0.1 ~ 0.3) ︰ to 0.8 ~ 1.3) ︰ to 0.5 ~ 1.0) ︰;
(2) under room temperature, the oxine that takes out (HQ) is dissolved in the dehydrated alcohol that takes out;
(3) under room temperature, the benzotriazole that takes out (BTA) is added appropriate water to dissolving completely, then add oxine (HQ) solution, additive and remaining water, mix, obtain the complex copper surface inhibiter that will prepare.
The present invention, because benzotriazole (BTA) and oxine (HQ) have inhibition synergistic effect to copper corrosion in electrolyte solution, mechanism is the bivalent cupric ion Cu that oxine (HQ) can produce with corrosion
2+there is coordination, form [Cu (II) – OC
9h
6c] complexing film, as the benefit of [Cu (I) – BTA] protective membrane fault location, add agent, at copper metallic face, form more fine and close protective membrane, thereby increased the protective capability to metal.
Embodiment
A preparation for complex copper surface inhibiter for copper slide fastener, comprises the steps:
(1) take respectively benzotriazole (BTA) 0.8g; Oxine (HQ) 1.0g; Additive 0.3g; Dehydrated alcohol 5g; Water 1000g;
Wherein, benzotriazole (BTA) is A.R. grade water-soluble benzotriazole (BTA); Oxine (HQ) is A.R. level oxine (HQ); Additive is that 30wt% sodium lauryl sulphate (SDS) aqueous solution and concentration are the 50% sulfuric acid solution that 1 ︰ (0.1 ~ 0.3) mixes by volume; Dehydrated alcohol is A.R. level dehydrated alcohol; Water is common clear water;
(2) under room temperature, the oxine that takes out (HQ) is dissolved in the dehydrated alcohol that takes out;
(3) under room temperature, the benzotriazole that takes out (BTA) is added appropriate water to dissolving completely, then add oxine (HQ) solution, additive and remaining water, mix, obtain the complex copper surface inhibiter that will prepare.
Complex copper surface inhibiter for the copper slide fastener of being prepared by the present embodiment, it uses processing working method to be: the copper zipper head after degrease, chain tooth (sequencing) are soaked in to described composite corrosion inhibitor 1 ~ 2 minute, take out standing 10 minutes, with clear water, embathe again, dry.Traditional benzotriazole (BTA) the treatment solution resistance to corrosion using of copper surface ratio that uses this composite corrosion inhibitor to process is stronger, through 24 hours salt spray testings and 48 hours salt spray testings, show, phenomenon is not yet found to be lost in the copper surface of using this complex copper surface inhibiter to process.
