Abstract
The invention discloses a magnesium alloy heating plate, which comprises a magnesium alloy body the inside of which a cavity is arranged, wherein the inner surface and the outer surface of the body are coated with anticorrosive coatings, the inner surface and the outer surface of the body are provided with silane coupling agent transitional films, and the anticorrosive coatings are coated on the silane coupling agent transitional films. The magnesium alloy heating plate uses the silane coupling agent transitional films generated in the process of the surface treatment of the magnesium alloy body as adhesive substrates of the anticorrosive coatings, so that the magnesium alloy heating plate is safe and environment-friendly, and has strong adhesive force and good binding performance of the anticorrosive coatings; and the anticorrosive coatings of the magnesium alloy heating plate is hard to fall off, thus the corrosion resistance of the magnesium alloy heating plate is greatly improved. Besides, chromate is not needed in the production process of the magnesium alloy heating plate, and the treatment process of corrosion prevention is convenient, safe and environment-friendly, and cannot pollute the environment.
Description
Technical field: the radiator that the present invention relates to a kind of radiator, particularly magnesium alloy system.
Background technology: generally the radiator as radiator all adopts material manufacturings such as cast iron, though cost is lower, weight greatly, not attractive in appearance, heat dispersion is also not ideal enough.The installation elegant in appearance, in light weight, easy of the radiator of magnesium alloy system, take up room little, its heat dissipation capacity be other radiator heat dissipation capacity 2-3 doubly.But the corrosion resistance of magnesium alloy is poor, and the radiator inner chamber is in 60-100 ℃ high temperature work down always, and the hot water of internal flow is bigger to the magnesium alloy corrosiveness, needs anti-corrosion treatment.The most frequently used magnesium alloy method for anticorrosion treatment is to use chromatedsolution that Mg alloy surface is handled and forms anticorrosive coat, but is to use the environmental pollution of chromate serious and toxic, does not meet the requirement of safety and environmental protection.Also some process for treating surface that does not contain chromium is because processing step is more, and energy resource consumption is big, the cost height.
Summary of the invention: at the deficiencies in the prior art, it is strong to the invention provides a kind of Corrosion Protection, the aluminium alloy radiator of environmental protection convenient for production.
The present invention includes inside and be provided with the magnesium alloy system body of cavity, be coated with anticorrosive coat on the inside and outside surface of body, be equipped with the silane coupler transition film on the inner surface of body and the outer surface, anticorrosive coat then applies attached on the silane coupler transition film.
The present invention utilizes at the bottom of the adherance of silane coupler transition film as anticorrosive coat that the body surface of magnesium alloy system handle to produce, safety and environmental protection, and strong adhesion and the anticorrosive coat excellent bonding performance that applies, difficult drop-off has improved the corrosion resistance of aluminium alloy radiator greatly.And the aluminium alloy radiator production process does not need chromate, and anticorrosive treatment process is convenient, and safety and environmental protection does not pollute the environment.
In practice, the anticorrosive coat that the body internal surface of aluminium alloy radiator applies can be an organosilicon silver powder coating, and the anticorrosive coat that outer surface applies can be a sheet allumen coating, makes like this to apply conveniently, and is dry easily, and corrosion resistance is stronger.
Further specify the present invention below in conjunction with drawings and Examples.
Description of drawings: accompanying drawing is the cross-sectional view of embodiment.
Embodiment: as shown in the figure, be equipped with silane coupler transition film 2 on the inner surface of the body 1 of AZ91D magnesium alloy system and the outer surface, 3 coatings of anticorrosive coat are attached on the silane coupler transition film 2, the anticorrosive coat 3 that body 1 inner surface applies is organosilicon silver powder coatings, and the anticorrosive coat 3 that outer surface applies is sheet allumen coatings.
The technology of carrying out anti-corrosion treatment is simpler, with the outer surface of the preparation solution of silane coupler film infiltration body 1, solidifies drying and obtains silane coupler transition film 2, again anticorrosive coating 3 dryings.Make the inner surface of body 1 also handle generation silane coupler transition film 2 then, again anticorrosive coating 3 dry getting final product.The preparation solution of general silane coupler film can adopt conventional methyl(3-mercaptopropyl) dimethoxysilane 1-5%, the aqueous solution of ethanol 20-30% of containing.
The aluminium alloy radiator that obtains is by the cross cut test standard of GB/T9286-1998 paint film, and corrosion-inhibiting coating adhesive force reaches 1 grade, and according to the salt spray test of GB/T10125-1997, the corrosion grading is more than or equal to 9 grades.
