Description
Technical field
The present invention relates to a kind of high rigidity chromium-free Dyclo composite film, belong to technical field of metal anti-corrosion.
Background technology
Dacromet Technology is a kind of novel anticorrosion process, becomes zinc-chromium coating at home, compared with traditional electrogalvanizing, and zinc-chromium coating corrosion resistance and good.Applying this technology can make metal surface have the performances such as corrosion-resistant, high temperature oxidation resisting, heat insulation and sealing, is widely used in the fields such as auto industry, electronic apparatus, Aero-Space, petrochemical industry, machine-building, engineering construction.Dacromet Technology mainly adopts chromating process, and chromate has toxicity and strong carcinogenesis due to it, and American-European countries prohibits the use, and China has also put into effect relevant policies and forbidden the application of Cr VI in the products such as electronic information.Along with the enhancing of global environmental consciousness, surface-treated Trend of Chrome-free has become a kind of trend, and Chrome-free plating, chromium-free deactivation, Trend of Chrome-free coating have started popular gradually.Chromium-free Dyclo is also Non-chromium Zn-al Coating, and first the renewal product as Dacroment (zinc-chromium coating) has generally been approved by automobile manufacture industry and received, and is also an important trend of whole metal rust preventing technical development.
Current chromium-free Dyclo coating hardness is lower, easy scratch, and pencil hardness only has 1H ~ 2H, for the workpiece needing wear-resisting requirement, cannot adopt chromium-free Dyclo technology.Cause wearing no resistance because film hardness is low, workpiece usually can be subject to grazing and scratch in transport, assembling, use procedure, affects the corrosion-resistant of coating, also affects the outward appearance of product.
SiO
2organic-inorganic hybridized coatings is the class high-performance organic-inorganic hybrid material that latest developments are got up, it take silica as inorganic component, be combined with organic phase by strong chemical bond, the characteristic such as can have the transparency, high rigidity, high adhesion force, corrosion-resistant, heat resistance, non-oxidizability, ageing resistance are strong, for coating metal surfaces, improve the decay resistance (with reference to patent: 201410222157.9 and 201410222500.X) of metal.
Summary of the invention
The purpose of this utility model is exactly the defect in order to make up prior art, provides a kind of high rigidity chromium-free Dyclo composite film.
The utility model is achieved through the following technical solutions:
A kind of high rigidity chromium-free Dyclo composite film, this high rigidity chromium-free Dyclo composite film is by the chromium-free Dyclo rete (2) be coated on matrix (1) and is coated in this this chromium-free Dyclo rete layer (2) outer field high rigidity SiO
2organic-inorganic hybrid films layer (3) is formed.The pencil hardness of described high rigidity chromium-free Dyclo composite film is 3H ~ 6H.
Preferably, chromium-free Dyclo rete (2) thickness is 5 ~ 30 μm, high rigidity SiO
2organic-inorganic hybrid films layer (3) thickness is 1 ~ 10 μm.
Relative to prior art, tool of the present invention has the following advantages and beneficial effect:
1, technical solutions of the utility model are by adopting suitable high rigidity SiO
2organic-inorganic hybrid films layer and chromium-free Dyclo rete complex superposition form, form corrosion resistance strong and there is the thin layer of high rigidity, be applicable to need high rigidity, component that salt spray resistance is greater than 500h, extend range of application and the market demand of chromium-free Dyclo coating.
2, the utility model is by having the high rigidity SiO of thin, high rigidity, the excellent properties such as transparent and corrosion-resistant in the coating of chromium-free Dyclo coating surface
2organic-inorganic hybrid films layer, on the basis not affecting the appearance color of chromium-free Dyclo coating own and corrosion resistance characteristic, improves hardness and the corrosion resistance of Bulk coat.
3, the utility model adopts Chrome-free coating technology, in protection of the environment and personal safety angle, has far-reaching social benefit.

Reference numeral annotates:
1 matrix; 2 chromium-free Dyclo retes; 3 high rigidity SiO
2organic-inorganic hybrid films layer.
Detailed description of the invention
As shown in Figure 1, the high rigidity chromium-free Dyclo composite film that the utility model provides is by the chromium-free Dyclo rete 2 be coated on matrix and be coated in the outer field high rigidity SiO of this this chromium-free Dyclo
2organic-inorganic hybrid films layer 3 is formed.This high rigidity chromium-free Dyclo composite film thickness is thin, nontoxic.Owing to combining corrosion resistance and the SiO of chromium-free Dyclo rete excellence
2the high rigidity of organic-inorganic hybrid films layer, the excellent properties such as transparent and corrosion-resistant, the salt spray resistance of the composite coating of both superpositions is greater than 500h, and appearance color is similar to the chromium-free Dyclo rete of individual layer.
Technical solutions of the utility model are by adopting suitable high rigidity SiO
2organic-inorganic hybrid films layer 3 and chromium-free Dyclo rete 2 complex superposition form, and form corrosion resistance strong and have the thin layer of high rigidity, be applicable to need high rigidity, component surface coating that salt spray resistance is greater than 500h.
The utility model high rigidity chromium-free Dyclo composite film adopts following technique to make: utilize chromium-free Dyclo production line precoating layer chromium-free Dyclo rete 2, dip-coating or spraying; Then at the dip-coating of chromium-free Dyclo film surface or spraying SiO
2organic-inorganic hybrid films layer 3, drying at room temperature 3 days or 100 DEG C of heating 2h are dried.
The utility model protection domain is not limited to the scope described by above-mentioned embodiment, and every technology distortion done according to the utility model know-why, all falls within protection domain of the present utility model.
