Description

A kind of portable multi-function blank is write film

Technical field

The utility model relates to a kind of blank and writes film, is specifically related to a kind of brand-new layer of structure, rollable and opens also and can write film by reusable portable multi-function blank.

Background technology

In processes such as teaching, meeting, exhibition, to pass on some information to people through writing on the blackboard usually, the writing on the blackboard tool kind that people use always is various, like the blank of traditional blackboard, metal material, electronic whiteboard etc.Traditional blackboard is write with chalk, can produce amounts of dust in the writing process, and Writer's both hands not only pollute the environment, make dirty; And be unfavorable for health; Traditional in addition blackboard is fixed, and will take certain space, the work of going out, travels, can't carry when playing.The blank of metal material be a kind of can erasable repeatedly writing implement.Be generally used for teaching, session discussing, or individual and family's account.Blank is equipped with special-purpose blank pen and writes, and still, the existing common blank of writing can only be used for writing of hydrate colour pen; Write the back writing and be difficult to wipe, and through long-term use, it is very smooth that the surface becomes; Write very difficultly, and this blank exists volume big, needs to be equipped with support; Installation is wasted time and energy, the defective that can't be convenient for carrying.Electronic whiteboard largely solved the defective that the blank of above blackboard of part and metal material is difficult to overcome, but its use must switch on, also can't use under the power free situation.

The blank that has occurred at present a kind of stratiform extrusion coating paper structure is on the market write film; Only need release liners torn to paste in the plane during use and just can use, this kind be write the dirt ash fouling that film has been eliminated the classroom chalk, the protection health; Overcome the fixed in shape of conventional white board again; Install and use inconvenience, defective such as not portable discloses a kind of stratiform like Chinese patent CN 202053773 U and has write film; Comprise surface layer and stick on the release layer of surface layer bottom through glue, said surface layer upper surface is furnished with one deck enhancement Layer.It has solved the problems referred to above to a certain extent; But still there is following problem: 1, paste release layer through glue; When using, the plane of the being pasted requirement of having ready conditions will exert an influence to the viscosity of glue such as surface or the more surface of dust that water is arranged; Come off easily, make troubles to the user; 2, after the paper film of pasting is torn, can't continue again to reuse, and can not move, be attached to certain position and just can only be fixed on this position; 3, the viscosity of this product glue too weak or all exist too by force not enough, glue viscosity is too weak can make paste insecure; Glue viscosity is stronger, and the plane itself that easily the paper film is attached is again destroyed, and such as wall skin, the easy vestiges that therefore stay glue of desktop, easy to clean does not bring pollution to environment.

The utility model content

In order to overcome the deficiency of prior art, the purpose of the utility model is to provide a kind of brand-new layer structure, rollable to open, be prone to tear, be prone to subsides, easy to clean, and can write film by reusable portable multi-function blank.

For addressing the above problem, the technical scheme that the utility model adopted is following:

A kind of portable multi-function blank is write film, and it comprises protective layer, PET body layer, silica gel following layer, silica gel layer and release layer from top to bottom successively.

In the utility model, described protective layer is the PET material layer, and it has effect high temperature resistant, that the protection blank is write film.

When the Practical Performance of white board film began to degenerate, reusable in order to realize, in the preferred scheme, the described PET body layer of the utility model was at least two-layer pet layer, and every layer of pet layer thickness is 10-200 μ m.

Said silica gel adhesion layer is one deck coupling agent layer that is coated between silica gel layer and the PET body layer.The coupling agent that is wherein adopted can be selected from a kind of in Organic Chromium complex compound, silanes, titanate ester and the aluminic acid compound.

The release layer that the utility model adopted is various separated type materials, a kind of as in release PET paper, release PE paper, Ge Laxin paper, mute light coating brown paper (CCK) or the model base stock.

The writing surface of the said PET body layer of the utility model is provided with the solid ink lay of ultraviolet light that synthetic resin is handled, and the solid ink lay of said ultraviolet light is unglazed frosting.The blank of this structure writes that film is convenient to write, anti-scratch, can reach robust effect, writes the back and wipes with blackboard eraser or flannelette and can reach more than 9000 times.

In the preferred scheme, the portable multi-function blank of the utility model is write film and is also comprised patterned layer, said patterned layer, be printed on above the PET body layer or below, between pet layer and protective layer or pet layer and silica gel adhesion layer.Play decoration and beautify the effect of writing film, bring the user pleasing visual effect.

Compare prior art, the beneficial effect of the utility model is: it is that stratiform is composite structured that the described blank of the utility model is write film, and manufacturing process is simple, uses easy to operate.The utility model replaces common glue layer with the environment-friendly silica gel layer, and blank is write film and can be pasted arbitrarily on various attachments surface, is prone to tear be prone to paste easy to clean, and can reuses.Very environmental protection simultaneously, the utility model blank is write the film rollable or is opened, and suitable school instruction, professor's rehearsal especially are fit to family's account and child's scribble; Carry easily, give at home, travel, educate and brought convenience.

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.
