Abstract
The invention relates to a nonphosphorus metal surface treatment agent and a use method of the nonphosphorus metal surface treatment agent. The nonphosphorus metal surface treatment agent consists of the following ingredients in part by weight: 5 to 20 parts of nanometer zirconium dioxide dispersing liquid with the concentration being 28 percent, 6 to 30 parts of hydrofluoric acid, 3 to 15 parts of propylene glycol, 6 to 20 parts of octavinyl polyhedral oligomeric silsesquioxane, 3 to 20 parts of acetic acid, 0.03 to 0.5 part of rare earth cerium salt, 1 to 5 parts of sodium hydroxide and 50 to 76 parts of deionized water. The nonphosphorus metal surface treatment agent has the advantages that a nanometer silane inorganic conversion film can be formed on the metal surface after the treatment on the metal. The nonphosphorus metal surface treatment agent belongs to a replacing product of the traditional phosphorizing liquid, no phosphor and no heavy metal are contained, the nonphosphorus metal surface treatment agent can work at room temperature and can be used for surface pre-treatment of various metals, the rusting phenomenon cannot be generated in 48 hours after the nanometer silane inorganic conversion film is formed on the metal surfaces of cold rolled steel plates and the like, and is then blown to be dry, and the requirement of corrosion resistance performance in the production work procedures is met.
Description
Technical field
The present invention relates to the metal conditioner field, exactly is a kind of phosphate-free metal surface treatment agent.
Background technology
Phosphatization is the metal surface treatment technology of using always.Because phosphatization liquid production technique is simple, with low content of technology, obtained using widely in China's metallic surface pre-treatment industry.But the phosphatization liquid in the phosphating process; Heavy metal ion such as phosphorous hydrochlorate, zinc, nickel, manganese in the main productss such as grease-removing agent; It handles direct discharging of waste water can cause serious pollution; Directly discharging can not increase enterprise cost again greatly, the long-established enterprise that has even do not have local newly-increased wastewater treatment line, and the pollution face that causes is enlarging step by step.Along with high development of social economy, problems such as energy shortage, environmental pollution, shortage of resources become increasingly conspicuous, and have caused and become global crisis, and are therefore more and more urgent to the energy-saving and emission-reducing product demand.Therefore, exploitation environment-friendly type phosphate-free metal surface treatment substitute technology has become the focus of countries in the world scientific research.
The novel non-phosphate metal conditioner is to solve industries such as present household electrical appliances, automobile, five metals manufacturing generally to use phosphorization treatment process to bring the serious environmental pollution problem; The not only environmental protection of this treatment agent; And energy-conservation, ten minutes vast potential for future development and high economic, social benefit are arranged.
Summary of the invention
The invention provides a kind of not only environmental protection, and can at room temperature use, can be used for pretreated phosphate-free metal surface treatment agent in multiple metallic surface and method of use thereof simultaneously.
For realizing that above-mentioned purpose the present invention adopts following technical scheme:
A kind of phosphate-free metal surface treatment agent is characterized in that being made up of following components by part by weight:
