Abstract
The invention discloses a projection writing color-coated sheet which comprises a steel sheet (1), a base paint layer (2) and a surface paint layer (3) which are arranged on the front of the steel sheet (1) from inside to outside and a base paint layer (4) and a surface paint layer (5) which are arranged on the back of the steel sheet (1) from inside to outside. The base paint layer (2) on the front of the steel sheet (1) is made of polyurethane resin, the surface paint layer (3) on the front of the steel sheet (1) is made of polyester resin, and the thickness of the surface paint layer (3) is 18-22mum. Due to the fact that the surface paint layer (3) on the front of the steel sheet (1) is made of the polyester resin which is low in gloss, so that the surface paint layer (3) can serve as a projection screen. The polyester resin has high bridging density, so that the surface paint layer (3) has good writing erasing performance. Therefore, the color-coated sheet achieves a projection function and facilitates writing.
Description
Technical field
The present invention relates to a kind of Coil Coating Products, specifically a kind of projection writing Coil Coating Products.
Background technology
Clipboard has, whiteboard is by extensive practicality at present, compared to the blackboard of chalk handwriting, the topmost function of whiteboard is the function of dust-free writing, and therefore it has no dust pollution, wiping is convenient, the feature of hand-written smoothness can be eliminated dust, environment protection health comprehensively, person's handwriting is more clear, writes more smooth.Therefore particularly at various offices, meeting room whiteboard, used in a large number.
General meeting room, except writing, also needs projection.Whiteboard is in the market generally white polyurethane resin priming paint and increases the Coil Coating Products that light acrylic resin transparent varnish is made, because acrylic resin transparent varnish gloss is higher, reach more than 90%, therefore whiteboard lustrous surface is higher, reflective obvious during projection, impact is watched.Owing to cannot reducing gloss, produce, usually need to be equipped with in addition a projection screen, some manufacturing enterprises are on frame, to have increased a pull-down projection screen for making it have projecting function.The projection screen being equipped with in addition has not only taken limited space, and office, instruction cost are strengthened.
Summary of the invention
Technical problem to be solved by this invention is to provide one has and writes, and has again the projection writing Coil Coating Products of two kinds of functions of projection.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of projection writing Coil Coating Products, comprise steel plate, steel plate front prime coat and top coat layer and steel plate reverse side prime coat and top coat layer from inside to outside from inside to outside, the prime coat material in described steel plate front is polyurethane resin, the top coat layer material in described steel plate front is mylar, and its thickness is 18-22 μ m.
The material that the top coat layer in described steel plate front adopts is mylar, and the top coat layer that material in polyester resin is made has the feature of low gloss, and therefore it can be used as projection screen and uses.
Meanwhile, in mylar, resin has higher bridge formation density, makes it have the good wiping of writing.
But, because the pliability of mylar is poor, easy embrittlement when stressed, therefore the thickness of the top coat layer in steel plate front is selected 18-22 μ m, makes it have the good wiping of writing on the one hand, prevents on the other hand its in use embrittlement.
And the prime coat material of described steel plate reverse side is polyurethane resin, the top coat layer material of steel plate reverse side is epoxy resin.
Usually, the prime coat thickness in described steel plate front is 4-6 μ m; The prime coat thickness of described steel plate reverse side is 2-5 μ m, and the top coat layer thickness of described steel plate reverse side is 7-11 μ m.As preferably, the prime coat thickness in described steel plate front is 5 μ m, and the top coat layer thickness in described steel plate front is 20 μ m, and the prime coat thickness of described steel plate reverse side is 3 μ m, and the top coat layer thickness of described steel plate reverse side is 8 μ m.
The present invention uses material in polyester resin at the top coat layer in steel plate front, material in polyester resin low gloss can be served as projection screen, and polyester finish coat bridge formation density is high, makes it have the good wiping of writing, thereby make Coil Coating Products both there is projecting function, be convenient to again write.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of projection writing Coil Coating Products, comprises steel plate 1, steel plate 1 front prime coat 2 from inside to outside and top coat layer 3 and steel plate 1 reverse side prime coat 4 and top coat layer 5 from inside to outside.Described prime coat 2,4 materials are polyurethane resin, top coat layer 3 materials in described steel plate 1 front are mylar, mylar has improved bridge formation density more than 20%, and therefore top coat layer 3 has the good wiping of writing, and top coat layer 5 materials of described steel plate 1 reverse side adopt epoxy resin.
Above-mentioned prime coat 2,4 materials can select note forever to make the polyurethane primer of selling outside paint industry (Kunshan) Co., Ltd, and the mylar of the top coat layer 3 in steel plate 1 front is remembered the polyester finish coat of making paint industry (Kunshan) Co., Ltd forever.
Projection writing Coil Coating Products of the present invention, take galvanized steel plain sheet as base material, first applies chemical pre-treatment medicament in the front of steel plate 1, and chemical pre-treatment medicament is mainly containing sexavalence chromic salts composition passivating solution, and passivating solution improves the adhesive force between priming paint and base material.
Then the prime coat 2 in coated steel plates 1 front, top coat layer 3, prime coat 2 thickness are 4-6 μ m, preferred thickness is 5 μ m; Top coat layer 3 thickness are 18-22 μ m, and preferred thickness is 20 μ m, and selection is mainly to consider that the pliability of mylar is poor like this, the problem of easy embrittlement when stressed.Thickness remains on 18-22 μ m, makes it have the good wiping of writing on the one hand, prevents on the other hand its in use embrittlement.
Then at the back side of steel plate 1, apply successively chemical pre-treatment medicament, as above-mentioned chemical pre-treatment medicament is mainly containing sexavalence chromic salts composition passivating solution, for improving the adhesive force between priming paint and base material.
Above-described embodiment does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
