Abstract
The invention develops a preparation method of an oil-removing and rust-removing two-in-one treating agent. The treating agent comprises phosphoric acid having a concentration of 85%, sodium molybdate, zinc dihydrogen phosphate, potassium chlorate, OP-10, triethanolamine, propane diacid and deionized water. The treating agent is advantageous in that: the treating agent has characteristics of energy conservation, pollution reduction, safety, efficiency, low cost, convenient operation, high quality, low price, and the like when compared with traditional alramenting and passivating treating liquids for steel, and the treating agent is a novel ideal cleaning product needed for the electroplating industry, the painting industry, the plastic-blasting industry, and the like.
Description
Technical field
The present invention relates to a kind of preparation method for the antirust rust-preventive agent of steel surface, relate in particular to
the preparation method of a kind of oil removing, antirust two-in-one treatment agent.
Background technology
According to national standard, steel surface, painting, before plastic-blasting and plating, all will carry out to steel surface the pre-treatment of phosphatization, passivation, to improve rust-preventing characteristic and the sticking power of steel surface.Therefore, phosphate conversion film processing is at present widely used on the products such as automobile, steamer, machinofacture, aerospace and household electrical appliance.Under the prerequisite of ensuring the quality of products, reduce treatment step as far as possible, shorten the treatment time, reduce processing cost and reduce and process injury, become important topic anxious pending in present steel field of surface treatment, therefore our company has developed the preparation method of a kind of oil removing, antirust two-in-one treatment agent, and by two order unifications, gained phosphatize phosphate coat has good rust-preventing characteristic.
Summary of the invention
The present invention has developed
the preparation method of a kind of oil removing, antirust two-in-one treatment agent, technical scheme of the present invention is: treatment agent consists of 85% phosphoric acid, Sodium orthomolybdate, primary zinc phosphate, Potcrate, OP-10, trolamine, propanedioic acid and deionized water.Optimum formulae is: treatment agent is that 0.6-1.0%, trolamine 1.0-1.4%, propanedioic acid 0.5-1.5% and deionized water form by 85% phosphoric acid 25-30%, Sodium orthomolybdate 0.2-0.4%, primary zinc phosphate 5.0-6.0%, Potcrate 0.4-0.8%, OP-10.Treatment agent outward appearance is water white transparency evenly without precipitation liquid.Concrete operation step: now a part of deionized water is added in container, under agitation add successively the Sodium orthomolybdate, primary zinc phosphate, Potcrate, OP-10, trolamine, the propanedioic acid that have weighed, after finishing, stir at normal temperatures 10min, under agitation add again 85% phosphoric acid, finish rear continuation and stir 30min, get final product to obtain treatment agent.Treatment temp: 15-40 ° C, the treatment time: 10-20min.
Superiority of the present invention: the treatment agent of this oil removing, antirust unification is compared with traditional steel surface phosphatization inactivating treatment liquid, have energy-conservation, the features such as dirt, safety, efficient, cost is low, easy to operate and of high quality and at a reasonable price are fallen, be a kind of new type ideal cleaning products indispensable in the industries such as plating, japanning, plastic-blasting.
