Abstract
The invention relates to a compound type rust solvent for the pretreatment of the spraying and the coating of the shell bin body of a mortar for a machine, comprising the following materials in percentage by weight: 10%-50% of phosphoric acid, 1%-10% of fluozirconate, 1%-5% of tartaric acid, 5%-20% of citric acid, 1%-10% of phytic acid, and the balance of tap water. A preparation method comprises the following steps: adding the tap water into a reaction kettle; starting a stirrer at normal pressure and temperature; stirring at the rotation speed of 150-250 turns/minute; adding the tartaric acid, the citric acid, the fluozirconate, the phytic acid and the phosphoric acid and stirring at the same time; finally sufficiently stirring for 25 to 35 minutes till a solution appears as purplish clear liquid; sampling, checking, emptying and packaging. The compound type rust solvent is used in a production line without residual acid liquor and corrosion action on workpieces, ensures a phosphating film layer and a coating layer to be intact, has stable technology, convenient operation and easy control and regulation without penetrating odor of rust melting working spray, also realizes the full-line normal temperature production and reduces the production cost.
Description
Technical field
The present invention relates to a kind ofization rust agent and preparation method thereof, particularly a kind of machine is with flying pig casing spray-coating pre-treatment compound type rust agent and preparation method thereof.
Background technology
Machine all will carry out bonderizing as last and generate the thin and fine and close phosphorization membrane of one deck at spray-coating with the flying pig casing.Its main effect is to improve its surperficial corrosion resistance nature; Improve the sticking power between matrix and the spray-on coating; But phosphatize phosphate coat can not form on rusty scale or oxide debris and grow; Phosphatize phosphate coat is only at no greasy dirt, and no rusty scale exposes on the workpiece surface of fresh metallic crystal the deposition continuous film forming takes place, and therefore thoroughly rust cleaning then is the prerequisite of phosphating process.
At the phosphating process production line; To machine with in the flying pig casing pre-treatment acid pickling and rust removing operation; Generally all adopt strong acid such as hydrochloric acid or sulfuric acid as rust remover; Excessive erosion takes place to workpiece surface in strong acid easily, also produces pungent acid mist simultaneously, must thoroughly neutralize the debris of strong acid with operation in the road down after the pickling.Machine is special with the flying pig body structure, has finedraw and tiny dead hole closely, in strengthening in any case with the processing of program; All can't the whole neutralizing treatment of residual acid solution in these slits and the dead hole be fallen, along with the prolongation of time, remain in the slit with dead hole in acid solution can come out by seepage flow; Directly destroy phosphorization membrane; Then destroy the spray-coating layer, thoroughly damaged the paint film system of spray-coating at last, have a strong impact on the spray-coating quality.
Summary of the invention
The purpose of this invention is to provide a kind of do not have pickling, non-corroding, rust cleaning effective, make derusting process is simplified, cost is low machine with flying pig casing spray-coating pre-treatment compound type rust agent and preparation method thereof, overcome the deficiency of prior art.
