But the PVC film of existing colorful covering membrane steel plate (PVC film coated plate) is mainly to adopt glue to cover on metal substrate, and the PVC film contains the composition of not environmental protection, and cost is higher.
The utility model content
Based on this, the purpose of this utility model is to provide a kind of hot transfer printing color painted steel strip.
Concrete technical scheme is as follows:
A kind of hot transfer printing color painted steel strip comprises metal substrate, and a side of described metal substrate is being provided with coating, prime coat, top coat layer, thermal transfer ink layer successively.
In embodiment, described thermal transfer ink layer is the dapple polyester film of seal therein.Described thermal transfer ink layer can increase the decorative effect of steel plate, reduces production costs, and improves the flexibility of production.
In embodiment, describedization coating is that thickness is the netted chemical conversion rete of Chrome-free of 1-2 μ m therein.The design of changing coating has strengthened the corrosion resistance of metal substrate, has also improved the adhesive force of metal substrate simultaneously; Back of the body enamelled coating can further strengthen the corrosion resistance of metal substrate, has also improved the flatness of metal substrate simultaneously; Top coat layer can strengthen corrosion resistance and the flatness of metal substrate again.
In embodiment, the opposite side of described metal substrate is being provided with coating, back of the body enamelled coating successively therein.
In embodiment, described thermal transfer ink layer is provided with protective film therein.Protective film can prevent in transit or other situation lower steel plates by scratch, pollution.
In embodiment, described metal substrate is cold-rolled steel sheet or galvanized steel plain sheet therein.
The utility model has the advantages that:
Hot transfer printing color painted steel strip of the present utility model, adopt the heat-transferring method time processing that heat transfer film is transferred on steel plate, have the advantage such as corrosion resistance, scratch resistance, aesthetic property of processing forming, thermal diffusivity, deep drawing quality, crushing resistance and the polyphosphazene polymer ester material of Metal Substrate concurrently, simultaneously because adopting the continuous roller coat explained hereafter of coloured picture plate, yield rate is high, and speed of production is fast, and cost is low, owing to not using traditional PVC film, therefore more environmental protection.

200, metal substrate; 201, change coating; 202, prime coat; 203, back of the body enamelled coating; 204, top coat layer; 205, thermal transfer ink layer; 206, protective film.
The specific embodiment
By the following examples the utility model is further elaborated.
With reference to figure 1, the described hot transfer printing color painted steel strip of the present embodiment comprises metal substrate 200, and a side of described metal substrate 200 is being provided with coating 201, prime coat 202, top coat layer 204, thermal transfer ink layer 205 and protective film 206 successively; The opposite side of described metal substrate 200 is being provided with coating 201, back of the body enamelled coating 203 successively.
Described thermal transfer ink layer is the dapple polyester film of seal.Described thermal transfer ink layer can increase the decorative effect of steel plate, reduces production costs, and improves the flexibility of production.
Describedization coating is that thickness is the netted chemical conversion rete of Chrome-free of 1-2 μ m.The design of changing coating has strengthened the corrosion resistance of metal substrate, has also improved the adhesive force of metal substrate simultaneously; Back of the body enamelled coating can further strengthen the corrosion resistance of metal substrate, has also improved the flatness of metal substrate simultaneously; Top coat layer can strengthen corrosion resistance and the flatness of metal substrate again.
The opposite side of described metal substrate is being provided with coating, back of the body enamelled coating successively.
Described thermal transfer ink layer is provided with protective film.Protective film can prevent in transit or other situation lower steel plates by scratch, pollution.
Described metal substrate 200 is cold-rolled steel sheet or galvanized steel plain sheet.
The preparation method of the described hot transfer printing color painted steel strip of the present embodiment is as follows:
(1) clean metal substrate (cold-rolled steel sheet or galvanized steel plain sheet), remove antirust oil, rust staining and dust that metallic substrate surfaces is adhered to, then oven dry.
(2) 2 sides at metal substrate all apply immersion coating, oven dry, formationization coating; Described immersion coating is the netted chemical composition coating of a kind of Chrome-free, and its thickness is 1 μ m-2 μ m, can increase corrosion resistance and the adhesive force of steel plate.
(3) the change coating surface in metal substrate one side applies one deck priming paint, forms prime coat.Back of the body enamelled coating can further strengthen the corrosion resistance of metal substrate, has also improved the flatness of metal substrate simultaneously.
(4) obtain applying one deck finish paint on prime coat in step (3), form top coat layer.Top coat layer can strengthen corrosion resistance and the flatness of metal substrate again.
