Description
Technical Field
The invention belongs to the technical field of metal coating pretreatment, and particularly relates to a metal surface pretreatment film forming liquid, and a preparation method and application thereof.
Background
In the metal pretreatment industry, china still takes phosphating as the main material, but the traditional phosphating process has mature technology, but the pollution to the environment is increased increasingly, and the serious phosphorus-rich pollution is caused by the large-scale use of phosphating agent, so that the plant in the water body is overgrown, and meanwhile, the propagation of a large number of bacterial organisms is accompanied in the lake. Phosphorus-rich pollution is also a killer of water organisms, and a great amount of propagation can rob oxygen in lakes, so that the oxygen-dependent organisms in the lakes can be in competition, and the living organisms die. The phosphating medicament also contains a large amount of heavy metals and high-strength cancerogenic substances (such as chromium, nickel, cobalt, sodium nitrite and the like) which are strictly controlled by the nation, a large amount of phosphating slag byproducts are also accompanied in the using process of the phosphating bath solution, the phosphating slag treatment difficulty which is strictly controlled by the environmental protection department is high, the cost is high, and the upper limit requirements of partial regional governments on the total phosphating slag treatment amount are met.
The early 21 st century, german hangao introduced a novel environment-friendly treatment ceramic agent which mainly adopts fluorozirconic acid as a basic film forming substance, a layer of zirconium dioxide film is deposited on the surface of metal by reaction, and the agent composition has no phosphorus, chromium and nickel, so that the agent has the advantages of environment protection to a certain extent, and meanwhile, a plurality of problems exist: (1) The medicament contains a large amount of fluorochemical agents, which cause a large amount of fluorine pollution; (2) Fluoride sediment with 5-10% of the phosphorization sediment amount is still accompanied in the use process of the pottery technology, and the treatment difficulty is quite large; (3) The method has the advantages that the method has great limitation on processing boards, and has serious defects on pickling boards, cast iron, carbon gray boards and the like, so that quality failure is caused.
