Abstract
The invention discloses a silver grey membrane treating agent for non-chromium and non-phosphorus iron and steel components. The silver grey membrane treating agent comprises the following components in percentage by weight: 2.5-4.5% of fluozirconic acid, 1.0-2.5% of nitric acid, 0.1-1.0% of tartaric acid, 0.1-0.4% of ammonium molybdate, 1.0-3.0% of citric acid, 0.1-0.6% of phytic acid, 0.3-1.2% of oxalic acid, 0.7-2.0% of hydrofluoric acid, 3-6% of triethanolamine, 1.2-2.0% of polyethylene glycol, 0.05-0.15% of defoaming agent and the balance of deionized water. The preparation method of the silver grey membrane treating agent comprises the following steps of: firstly adding calculated and weighed water into a stainless steel reaction kettle while a rotating speed is controlled to be 60r/min, then sequentially and slowly adding calculated and weighed fluozirconic acid, nitric acid, tartaric acid, ammonium molybdate, citric acid, phytic acid, oxalic acid, hydrofluoric acid, triethanolamine, polyethylene glycol and defoaming agent into the reaction kettle under the condition of stirring for 10 minutes after each raw material is added, and finally continuing stirring until a light brown transparent solution is obtained.
Description
Technical field
The present invention relates to a kind of steel part epithelium treatment agent and preparation method, especially a kind of performance index can reach chromium-phosphorus-free steel part silver gray epithelium treatment agent and the preparation method of technical requirements.
Background technology
Metal component surface is because of grease, floating rust, heavily rust, oxide skin and welding high-temperature oxide etc., therefore in the past before the art breading such as spray-coating, all that above-mentioned oily scale etc. is disposed and mostly processed by phosphate conversion, the black, silver gray or the color phosphor hydrochlorate conversion film (epithelium) that make its Surface Creation one deck have certain roughness, porousness, adsorptivity are to strengthen the workpiece surface rotproofness, to improve workpiece surface and the sticking power that is coated with interlayer or other organic surface treatment interlayers.Being applied at present the phosphating agent that replaces not environmental protection before the spray-coating of metallic surface has Nano type, vitrification type, silane type etc. multiple, but the skin membrane appearance color that forms on surface of steel workpiece is all to present golden yellow or iris, can not satisfy the user and must be silver-gray requirement to skin membrane.
Summary of the invention
The present invention is in order to solve the existing above-mentioned technical problem of prior art, the chromium-phosphorus-free steel part silver gray epithelium treatment agent and the preparation method that provide a kind of performance index can reach technical requirements.
Technical solution of the present invention is: a kind of chromium-phosphorus-free steel part silver gray epithelium treatment agent is characterized in that being made of the component of following mass percent: fluorine zirconic acid 2.5 ~ 4.5%, nitric acid 1.0 ~ 2.5%, tartrate 0.1 ~ 1.0%, ammonium molybdate 0.1 ~ 0.4%, citric acid 1.0 ~ 3.0%, phytic acid 0.1 ~ 0.6%, oxalic acid 0.3 ~ 1.2%, hydrofluoric acid 0.7 ~ 2.0%, trolamine 3 ~ 6%, polyoxyethylene glycol 1.2 ~ 2.0%, defoamer 0.05 ~ 0.15% and deionized water surplus.
A kind of preparation method of chromium-phosphorus-free steel part silver gray epithelium treatment agent described above, it is characterized in that carrying out as follows: the water that first will calculate weighing joins in stainless steel cauldron, start agitator, controlling rotating speed is 60 rev/mins, fluorine zirconic acid, nitric acid, tartrate, ammonium molybdate, citric acid, phytic acid, oxalic acid, hydrofluoric acid, trolamine, polyoxyethylene glycol, the defoamer that then will calculate successively weighing join in reactor slowly, often added a kind of raw material stirring 10 minutes, and continued at last to be stirred to solution and be light brown transparence liquid.
The present invention not only all technical all satisfies outside the requirements of chromium-phosphorus-free epithelium processing, and formed skin membrane is silver gray on surface of steel workpiece, can fully and completely substitute the phosphating agent of not environmental protection.
