Abstract
The invention discloses a general phosphate agent for cast iron, cast steel, a hot-rolled plate, a pickling board and a cold-rolled plate and a preparation method thereof. The general phosphate agent is prepared from the following raw materials in percentage by weight: 8%-15% of phosphoric acid, 0.5%-1.5% of zinc oxide, 0.1%-0.2% of potassium chlorate, 0.1%-0.2% of nickel carbonate, 1%-2.5% of tartaric acid, 5%-10% of synthesizing phosphating additive, 0.8%-1.8% of butylcellosolve, 0.1%-0.5% of soak-degreasing dedicated surfactant, 0.8%-1.8% of isopropyl alcohol and the balance of water. The preparation method comprises the following steps of: adding the calculated and weighted water into a still, successively and slowly adding the calculated and weighted phosphoric acid, zinc oxide, potassium chlorate, nickel carbonate, tartaric acid, synthesizing phosphating additive, butylcellosolve, soak-degreasing dedicated surfactant and isopropyl alcohol into the still, stirring to dissolve fully while each raw material is added, continuing to stir after all of the raw materials are added until the solution presents a light green clear liquid.
Description
Technical field
The present invention relates to special phosphorization agent and preparation method before a kind of metal spraying application, especially a kind of simple to operate, film forming speed is fast, can generate on the metal surface with metallic matrix mortise and the preparation method of the general phosphate agent of the cast iron of the phosphorization membrane of crystallization even thickness, cast steel, hot-rolled sheet, acid-cleaning plate, cold-reduced sheet.
Background technology
Metal all must carry out conversion processing to its surface before spray-coating, makes it generate conversion film.Conversion film has porousness, uniform and delicate, and coating penetrates into the sticking power that effectively can increase spray-on coating in hole, thus improves the solidity to corrosion of metal.Conversion film comprises phosphatize phosphate coat, passive film, organic membrane, rare-earth conversion coatings and colloidal sol silane film etc., wherein phosphatize phosphate coat is that it is in the salts solution of main body that metallic element is immersed in containing the specific acid phosphate such as Zn, Ni, Mn, Fe, add various composite additive simultaneously, through chemical treatment, at the Surface Creation of metallic element, there is the phosphate conversion film that certain thickness is insoluble in water.Basic technology is: comprehensive treating process change into process → cold wash → hot water wash → seasoning → under turn electrostatic powder coating application.At present, carry out usually needing when comprehensive treating process changes into process different treatment agents for different metal workpiece such as cast iron, cast steel, hot-rolled sheet, acid-cleaning plate, cold-reduced sheets, of a great variety being difficult to manages and operation.
Summary of the invention
The present invention is the above-mentioned technical problem in order to solve existing for prior art, there is provided a kind of simple to operate, film forming speed fast, can generate on the metal surface with metallic matrix mortise and the preparation method of the general phosphate agent of the cast iron of the phosphorization membrane of crystallization even thickness, cast steel, hot-rolled sheet, acid-cleaning plate, cold-reduced sheet.
Technical solution of the present invention is: the general phosphate agent of a kind of cast iron, cast steel, hot-rolled sheet, acid-cleaning plate, cold-reduced sheet, it is characterized in that being made up of the raw material of following mass percent: phosphoric acid 8 ~ 15%, zinc oxide 0.5 ~ 1.5%, Potcrate 0.1 ~ 0.2%, nickelous carbonate 0.1 ~ 0.2%, tartrate 1 ~ 2.5%, comprehensive bonderizing auxiliary agent 5 ~ 10%, ethylene glycol monobutyl ether 0.8 ~ 1.8%, soak degreasing special surfactant 0.1 ~ 0.5%, Virahol 0.8 ~ 1.8% and water surplus.
A kind of above-mentioned cast iron, cast steel, hot-rolled sheet, acid-cleaning plate, the preparation method of the general phosphate agent of cold-reduced sheet, it is characterized in that carrying out as follows successively: first join in reactor by calculating the water weighed, start agitator, controlling rotating speed is 60 revs/min, then the phosphoric acid weighed will be calculated, zinc oxide, Potcrate, nickelous carbonate, tartrate, comprehensive bonderizing auxiliary agent, ethylene glycol monobutyl ether, soak degreasing special surfactant, Virahol joins in reactor successively slowly, often add a kind of raw material and be all stirred to abundant dissolving, after whole raw material adds, continuing to be stirred to solution is greenish transparent liquid.
The present invention is common to the material workpiece such as cast iron, cast steel, hot-rolled sheet, acid-cleaning plate and cold-reduced sheet, workpiece for unlike material processes without the need to classification, management and simple to operate, film forming speed is fast, can generate the extremely strong phosphatize phosphate coat of fine crystallization, adsorptivity at different metals workpiece surface, phosphorization membrane quality reaches standard (1 ~ 3g/m
2) requirement, the lubricating oil of adsorbable q.s and being evenly distributed, can improve the wear resistance of workpiece, solidity to corrosion and oilness, conforming product rate is improved (more than 98%).
