Background technology
Steel plate is a kind of important engineering material, but steel plate is in use because of corrosion reduction of service life or to lose the loss that its use value brings be also quite huge.Particularly, along with the development of modern industry, the appearance in a collection of infant industry field and the construction of many modern projects, to having higher requirement in waterproof decay resistance and the service life of steel.
Technical information about corrosion-resistant coating layer steel plate can be seen in disclosed Chinese patent literature, typically as CN101435078B recommends to have " non-chrome resin composition, steel plate is carried out to surface-treated method and steel plate ", this patent scheme can be cashed the technique effect of the 0045th section, its description, the coating that is particularly combined under steel plate use state a side surface outward has the high and good strong point of tear-resistant effect of intensity, but the adhesive strength mutually bonding with surface of steel plate, density, water-resistance, leakage resistance, adhesive strength, weatherability (and hot and cold resistance), low temperature flexibility, chemicals-resistant corrosion and electrical property etc. relatively fragility are its shortcoming.
For above-mentioned prior art, the applicant makes a useful improvement, and has formed technical scheme described below.
Summary of the invention
Task of the present utility model is to provide a kind of and contributes to significantly to improve water-resistance, leakage resistance, weatherability, chemical resistance and low temperature flexibility and use the corrosion-resistant color coating layer steel plate of the waterproof increasing the service life.
Task of the present utility model completes like this, the corrosion-resistant color coating layer steel plate of a kind of waterproof, comprise steel matrix, be positioned at the transition zone of steel matrix side surface outward under use state and be positioned at the surperficial waterproof anti-corrosion layer of transition zone, be characterised in that: form and have immersion coating towards the surface of a side of described transition zone at described steel matrix, described transition zone comprises primer coating and topcoat, primer coating is incorporated into the surface of described immersion coating, and topcoat is incorporated into the surface of primer coating, described waterproof anti-corrosion layer is incorporated into the surface of topcoat.
In a specific embodiment of the present utility model, the thickness of described steel matrix is 0.5-1.5mm, and described steel matrix is galvanized steel plain sheet or the surperficial Al-Zn coated steel that is coated with aluminium zinc layer that surface is coated with zinc layer.
In another specific embodiment of the present utility model, the thickness of described zinc layer is 30-75 μ m; The thickness of described aluminium zinc layer is similarly 30-75 μ m.
In another specific embodiment of the present utility model, the thickness of described immersion coating is 5-15 μ m; Described primer coating and the thickness of topcoat are 15-45 μ m; The thickness of described waterproof anti-corrosion layer is 95-150 μ m.
In another specific embodiment of the present utility model, described primer coating and topcoat are coloured coating.
Also have in a specific embodiment of the present utility model, described immersion coating is chromate coating.
More of the present utility model and in a specific embodiment, described chromate coating is that chemical valence is the hexavalent chromate coatings of positive 6 valencys.
The technical scheme that the utility model provides, owing to forming and having immersion coating towards a side surface of transition zone at steel matrix, thereby can significantly strengthen transition zone to steel matrix adhesive force and can significantly improve resistance to corrosion; Because transition zone is made up of the end, topcoat and waterproof anti-corrosion layer is incorporated into the surface of topcoat, thereby there is excellent water resistant anti-leakage, weather-proof, chemical resistance and low temperature flexibility and excellent strength, in water, soak 400h without peeling off, without bubble phenomenon, through neutral salt spray test 720h, transition zone is without cracking, without peeling off situation generation.
Brief description of the drawings
Fig. 1 is the example structure figure of the corrosion-resistant color coating layer steel plate of the utility model waterproof.
Detailed description of the invention
For the auditor that the makes Patent Office especially public can be expressly understood technical spirit of the present utility model and beneficial effect more, applicant elaborates the mode with embodiment below, but be not all the restriction to the utility model scheme to the description of embodiment, any done according to the utility model design only for pro forma but not substantial equivalent transformation all should be considered as the technical solution of the utility model category.
