Background technology
The positive spray lamp of Weak solvent is the update product of the positive spray lamp of indoor water-based, and it has taken into account the advantage of water-base ink and solvent-based inks, and it is high to have print resolution, and the feature of environmental protection is good, the features such as weatherability is good, waterproof.
But, the positive spray lamp of tradition Weak solvent is coated with one deck ink absorbing layer in transparent PET or milky white PET, often there is flaw point in product coating surface, air brushing picture is long for drying time, coating is easily scratched, cut out sample edge coating and easily occur that efflorescence is dropped, the electrostatic produced during printing can cause that paper feed has some setbacks, picture grows dim.
Utility model content
The purpose of this utility model is to provide the positive spray lamp of a kind of novel Weak solvent, has that quality consistency is excellent, production efficiency is high.The feature that printing effect is good He easy to use.
The utility model can be achieved through the following technical solutions:
The utility model discloses the positive spray lamp of a kind of novel Weak solvent, comprise the ink absorbing layer of stratiform laminating, adhesive layer, substrate layer and overcoat, described adhesive layer is arranged between described ink absorbing layer and described substrate layer, and the outside of described substrate layer is compounded with described overcoat.On concrete function, ink absorbing layer carries main body as ink receptive, adhesive layer plays bonding effect ink absorbing layer and substrate layer compound integrally, and substrate layer provides product stiffness and flatness as product main support body, and overcoat plays anti-skid wearable antistatic property.By adopting the mode of bonding that ink absorbing layer is compounded in substrate layer, the defect effectively avoiding traditional ink absorbing layer to be directly coated on substrate layer occurring, surface uniformity is good, decreases the probability that flaw point produces, improves the uniformity of quality; Meanwhile, avoid the long impact that production efficiency is caused drying time of air brushing picture in process of production, effectively improve production efficiency; After bonding, the structural stability of substrate layer and ink absorbing layer improves, and minimizing ink absorbing layer is scratched and cuts out sample edge blotting and easily occurs the appearance that efflorescence is dropped, and ensure that lamp sheet has good printing effect.In addition, by arranging overcoat, the electrostatic that overcoat can produce when printing can cause that paper feed has some setbacks, picture grows dim, and improves the convenience of use.
Described ink absorbing layer is PVC film layer, and described substrate layer is transparent PET film layers.PVC film layer has that blotting speed is fast, print screen is bright-coloured, resolution is high, color reducibility is good, the semi-transparent even light of material, waterproof, not easily to shrink and the strong feature of weatherability, effectively ensure that the printing effect of lamp sheet as ink absorbing layer.
Described adhesive layer is compound adhesive water layer, effectively ensures that the PVC film layer of lamp sheet and PET film layers are adhered consistent more, the stability of structure after guarantee lamp sheet compound.
Described overcoat is anti-skidding corrosion-resistant static layer, forms anti-skidding corrosion-resistant static layer, make to unreel adhesion by the anti-skidding liquid antistatic of outside coating film at substrate layer, prints paper feed smooth and easy non-slip.
The thickness of described ink absorbing layer is greater than described substrate layer, and the thickness of described PVC film layer is 75 ~ 150 microns.
The positive spray lamp of a kind of novel Weak solvent of the utility model, has following beneficial effect:
The first, quality consistency is excellent, by adopting the mode of bonding that ink absorbing layer is compounded in substrate layer, the defect effectively avoiding traditional ink absorbing layer to be directly coated on substrate layer occurring, surface uniformity is good, decrease the probability that flaw point produces, improve the uniformity of quality;
The second, production efficiency is high, avoids the long impact caused production efficiency drying time of air brushing picture in process of production, effectively improves production efficiency;
Three, printing effect is good, and after bonding, the structural stability of substrate layer and ink absorbing layer improves, and minimizing ink absorbing layer is scratched and cuts out sample edge blotting and easily occurs the appearance that efflorescence is dropped, and ensure that lamp sheet has good printing effect;
Four, easy to use, by arranging overcoat, the electrostatic that overcoat can produce when printing can cause that paper feed has some setbacks, picture grows dim, and improves the convenience of use.
Detailed description of the invention
In order to make those skilled in the art person understand the technical solution of the utility model better, below in conjunction with embodiment and accompanying drawing, the utility model product is described in further detail.
As shown in Figure 1, the utility model discloses the positive spray lamp of a kind of novel Weak solvent, comprise the ink absorbing layer 1 of stratiform laminating, adhesive layer 2, substrate layer 3 and overcoat 4, described adhesive layer 2 is arranged between described ink absorbing layer 1 and described substrate layer 3, and the outside of described substrate layer 3 is compounded with described overcoat 4.Described ink absorbing layer 1 is PVC film layer.Described adhesive layer 2 is compound adhesive water layer.Described substrate layer 3 is transparent PET film layers.Described overcoat 4 is anti-skidding corrosion-resistant static layer.The thickness of described ink absorbing layer 1 is greater than described substrate layer 3, and the thickness of described PVC film layer is 75 ~ 150 microns.
The above, be only preferred embodiment of the present utility model, not does any pro forma restriction to the utility model; The those of ordinary skill of all industry all can shown in by specification accompanying drawing and the above and implement the utility model swimmingly; But all those skilled in the art are not departing within the scope of technical solutions of the utility model, disclosed above technology contents can be utilized and make a little change, modify with differentiation equivalent variations, be Equivalent embodiments of the present utility model; Meanwhile, all according to substantial technological of the present utility model to the change of any equivalent variations that above embodiment is done, modify and differentiation etc., within the protection domain all still belonging to the technical solution of the utility model.
