Abstract
The invention provides a novel treating agent for a galvanized plate vitrification membrane layer. The treating agent comprises the following constituents: 0.02-4% of a rare earth compound, 0.1-4% of a template agent, 0.01-0.8% of an inorganic solution, 0.01-5% of an interfacial modifier and 0.01-5% of a buffering agent, and further comprises 0.01-3% of silane liquid, 0.1-4% of zirconium fluoride, and the balance of water. According to the novel treating agent disclosed by the invention, before vitrification, the silane liquid is added to greatly improve the bonding performance of a galvanized plate, molding powder and paint; zirconium fluoride can be used for improving the antiseptic property of the galvanized plate and play the mold layer protecting function on the galvanized plate; the treating agent is reasonable in proportion, greatly improves the properties of the galvanized plate, and improves the spraying efficiency in the later stage.
Description
Technical field
The present invention relates to the technical field of galvanized sheet surface vitrification rete, particularly relate to a kind for the treatment of agent that can promote galvanized sheet and vitrification rete.
Background technology
Iron and steel usually needs to carry out pre-treatment before carrying out application; comprise the technique such as oil removing, rust cleaning; chemical pre-processing method also will form one deck chemical conversion film on the surface of iron and steel usually; the existing certain antiseptic power of this conversion film; can avoid returning rust in the part time of short duration before spraying; also can increase the roughness of piece surface, strengthen the bonding force of coating and substrate.Vitrified agent is a kind of response type pre-treatment chemical of phosphate free, and not phosphorous and heavy metal, meets European Union ROHS environmental requirement, is particularly suitable for iron and steel, zinc surface process.Bonding force and the corrosion resistance nature of application can be strengthened.Under being applicable to room temperature, spray or dip treating technique, the coating coupling of energy and various model.
Disclose the without phosphorus vitrification treatment solution of a kind of selfreparing for galvanized sheet in patent (CN 102965653 A), formed the unformed film of one deck densification by template self-assembly, film
Layer breakage has self-reparing capability, effectively improves erosion resistance and the sticking power of zinc coating.But late stage process needs the molding powder, paint etc. of interpolation poor with the bonding properties of zinc-plated plate, molding powder or paint are not easy to be attached on galvanized sheet, and the effect of shaping mould during zinc-plated Sheet Metal Processing is not very desirable, therefore, the problem solving this class seems particularly important.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind for the treatment of agent of Novel galvanizing plate vitrification rete, by adding a kind of promotor, to improve the bonding properties of galvanized sheet and molding powder, paint.
In order to solve the problem, the invention provides a kind for the treatment of agent of Novel galvanizing plate vitrification rete, the moiety of this treatment agent includes:
Rare earth compound 0.02-4%, template 0.1-4%, inorganic solution 0.01-0.8%, interface modifier 0.01-5%, buffer reagent 0.01-5%, also comprise promotor 0.01-3% and Zirconium tetrafluoride 0.1-4%, and surplus is water.
Further improvement is: described promotor is made up of silane liquid.
The invention has the beneficial effects as follows: the present invention can improve the bonding properties of galvanized sheet and molding powder, paint greatly by adding a kind of silane liquid before vitrification; and by the antiseptic property using Zirconium tetrafluoride can improve galvanized sheet, mold layer provide protection is played to galvanized sheet.Reasonable ratio of the present invention, substantially increases the performance of galvanized sheet, and improves the spray efficiency in later stage.
