Abstract
The utility model discloses a three colored coating steel sheets that dry by fire of three scribbles of highlight mainly comprises substrate, chemical coating, priming paint, finish paint, finishing coat layer, protection film, its characterized in that: the front surface and the bottom surface of the base material are both provided with a chemical coating and a primer, on the basis, the primer on the front surface is sequentially coated with a finish paint layer and a finishing paint layer, and the uppermost surface is stuck with a protective film. The utility model discloses surface quality is high, and the glossiness is high, has good surface decoration effect and corrosion resisting property, progressively at the household electrical industry and prevent trades such as fire door, cupboard, elevator, boats and ships and replace two colored coating steel sheet products of scribbling two and drying by fire.
Description
Technical field
The utility model relates to the new type composite board technical field, particularly a kind of high smooth three-coat three-baking color painted steel strip.
Background technology
Color painted steel strip (Coil Coating Products) generally is that the three kinds of base materials of galvanized steel plain sheet, cold-rolled steel sheet, aluminium sheet with rolling are main surperficial cleaning by degreasing, chemicalpiston processing, the product of a kind of precoating organic coating that applying coatings and baking form after substrate surface forms one deck chemical composition coating of carrying out.Color painted steel strip has mechanical strength, the processing characteristics of steel plate concurrently, and therefore the mechanical property of macromolecular material, corrosion resistance, ornamental are widely used in building decoration, household appliance appearance decoration, furniture, auto industry etc.
Coil Coating Products is a staple product metallurgical and Surface Treatment Engineering that chemical industry combines; Color painted steel strip has lightweight, attractive in appearance and good Corrosion Protection as sufacing treatment product coated steel sheet; Can directly process again; It provides a kind of novel raw material for building industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electric utility etc., played with steel for wood, efficient construction, energy savings, prevent good result such as pollution.
At present main use still traditional two be coated with two bakings product, two to be coated with two baking products relatively poor at surface effect, service life is short, surface gloss is low, corrosion-resistant, pollution resistance are poor, the cleaning that needs often flushing to keep Coil Coating Products.
Summary of the invention
The purpose of the utility model provides a kind of high smooth three-coat three-baking color painted steel strip; Surface quality is high; Glossiness is high; Have surface of good decorative effect and decay resistance, progressively industries such as household electric appliances and fireproof door, cabinet, elevator, boats and ships replace two be coated with two bakings the color painted steel strip product.
The technical scheme that the utility model adopts is: a kind of high smooth three-coat three-baking color painted steel strip; Mainly constitute by base material, change coating, priming paint, finish paint, Lacquer finish enamelled coating, diaphragm; It is characterized in that: base material front, bottom surface be having coating and priming paint all; On this basis, on the priming paint in front, apply finish paint, Lacquer finish enamelled coating successively, and stick diaphragm topmost.
Said base material is cold-rolled steel sheet or hot-dip galvanizing sheet steel.
Saidization coating layer thickness 1 ~ 2 μ m is distributed in the base material two sides, is after removing antirust oil that substrate surface adheres to, rust staining, dust etc., carries out chemicalpiston at the substrate surface of cleaning and handles the netted chemical composition coating of formed Chrome-free.
Said priming paint thickness 5 ~ 8 μ m are coated in the two sides of color painted steel strip respectively.Priming paint at the color painted steel strip back side is also referred to as back of the body lacquer.
Said finish paint thickness 10 ~ 15 μ m are coated in the front of color painted steel strip.
Said finishing varnish thickness 6 ~ 10 μ m are coated in the front of color painted steel strip, on finish paint.
Said diaphragm thickness 40 ~ 50 μ m.
The usefulness of the utility model is: be coated with product with existing two bakings two and compare, have higher surface quality, glossiness is high, has better surface decoration effect, and the improvement through sandwich construction has promoted decay resistance.The utility model adopts three-coat three-baking, and a plurality of protective layers are arranged.In conjunction with the different protection layer, considered match colors property of scoring resistance, resistance to impact, radiation resistance, gloss, anti-efflorescence, different parts etc. from specious aspect.
Description of drawings
Accompanying drawing is the utility model sketch map.
Among the figure: 1 is base material, and 2 for changing coating, and 3 is priming paint, and 4 is finish paint, and 5 is the Lacquer finish enamelled coating, and 6 is diaphragm.
The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
Adopt the three-coat three-baking roller coat unit of setting up voluntarily, undertaken by following process flow:
Use cold rolling or hot-dip galvanizing sheet steel is made base material (1), earlier base material (1) two-sided carried out alkali cleaning and handle (removing surface impurity and greasy dirt), oven dry.
At the two-sided roller coat masking liquid of base material (1), formationization coating (2) is to be the netted chemical composition coating of basic framework with Cr6+ and Cr3+, improves the corrosion resisting property and the enhancement coating adhesive force of steel plate.Dry through steam.
Prime (3) at base material (1) positive and negative, priming paint (3) is carried out baking-curing.
Essence is coated with finish paint (4) on priming paint (3) basis in base material (1) front, and heating is cured.
On finish paint (4), cover and be coated with coating varnish (5), through being heating and curing.
After the cooling, on coating varnish (5), stick diaphragm (6).
Wherein, the paint solidification temperature is preferred: 224 ℃ ~ 232 ℃.
Processing through above program; Increased the tack between base material (1) and other each coatings; Improve the anti-corrosive properties of base material and the durability of coating, improve the surface brightness of color painted steel strip, have higher surface quality; Glossiness is high, has better surface decoration effect and decay resistance.
Claims (6)
