Description
Technical field
The present invention relates to metal conditioner field, is exactly a kind of phosphate-free metal surface treatment agent.
Background technology
Phosphatization is conventional metal surface treatment technology.Because Phosphating Solution production technique is simple, with low content of technology, obtain in China's metallic surface pre-treatment industry and use widely.But the Phosphating Solution in phosphating process, the heavy metal ion such as phosphate-containing, zinc, nickel, manganese in the main productss such as grease-removing agent, its process direct discharging of waste water can cause serious pollution, directly do not discharge and greatly can increase enterprise cost, some long-established enterprises even do not have local newly-increased wastewater treatment line, and the pollution face of causing is expanding step by step.Along with socioeconomic high speed development, the problems such as energy shortage, environmental pollution, shortage of resources become increasingly conspicuous, and have caused and become global crisis, therefore more and more urgent to the demand of energy-saving and emission-reducing product.Therefore, the focus that environment-friendly type phosphate-free metal surface treatment substitute technology has become countries in the world scientific research is developed.
Novel non-phosphate metal conditioner solves the industries such as current household electrical appliances, automobile, five metals manufacture generally to use phosphorization treatment process to bring serious problem of environmental pollution, the not only environmental protection of this treatment agent, and energy-conservation, there are very vast potential for future development and higher economical, societal benefits.
Summary of the invention
The invention provides one not only environmental protection, and can at room temperature use, can be used for phosphate-free metal surface treatment agent and the using method thereof of various metals surface preparation simultaneously.
The present invention adopts following technical scheme for achieving the above object:
