Abstract
The invention discloses a phosphating solution for aluminum product surface treatment. The phosphating solution is prepared from the following raw materials in parts by weight: 32-36 parts of 60-65% phosphoric acid, 10-12 parts of oxalic acid, 5-8 parts of crylic acid, 2-9 parts of hydrofluoric acid, 4-8 parts of zinc dihydrogen phosphate, 1.2-3.2 parts of ammonium molybdate, 2.5-3.5 parts of chromium sulfate, 0.2-1.4 parts of nickel nitrate, 0.6-1.2 parts of cobalt naphthenate, 1.5-2.8 parts of tetrabasic zinc chromate, 4.5-6.5 parts of an antifoaming agent, 0.5-1.2 parts of a dispersing agent and 35-40 parts of distilled water. The phosphating solution is simple and practical in formula. A metal workpiece is immersed in the phosphating solution, and a water-insoluble crystalline phosphate conversion coating can be deposited and formed on the surface of the metal workpiece at normal temperature. The coating layer is of a micropore structure, is firmly combined with a substrate, has good adsorbability, lubricity and corrosion resistance and high electrical insulating property, and does not stick molten metal.
Description
Technical field
The present invention relates to a kind of technical field of Phosphating Solution, particularly relate to a kind of aluminum products surface treatment Phosphating Solution.
Background technology
Iron and steel parts all will do antirust treatment, common way is sprayed paint, and in order to increase the bond strength of coating and steel plate before spraying paint, the bonderizing before all will spraying paint to iron and steel parts, make iron and steel parts outside form a kind of similar honeycomb-like tissue, increase cohesive strength.But it is many to there is the residue produced in muddiness, parkerizing process in existing Phosphating Solution, and incidental expenses area is little, and needs temperature high, the shortcomings such as lost labor.
At present, the existing method processed metallic surface, not only complex procedures, labour intensity large (especially processing the hardware got rusty), efficiency are low, and contaminate environment.Particularly after rust cleaning, hardware is faced with again the problem of getting rusty, and needs to carry out antirust treatment or rotproofing again.
Summary of the invention
The object of this invention is to provide a kind of aluminum products surface treatment Phosphating Solution, the present invention fills a prescription simple and practical, metal works is invaded Phosphating Solution, water-fast crystal type phosphate conversion film can be formed at normal temperatures at surface deposition, this rete is microvoid structure, be combined firmly with matrix, there is good adsorptivity, oilness, solidity to corrosion, do not adhere to molten metal and higher electrical insulating property.
The technical solution used in the present invention is as follows:
