Abstract

The invention discloses a PET (polyethylene terephthalate) composite writing film formed by sequentially stacking the structural layers including a writable anti-scratch layer, a transparent PET structural layer, a colorable synthetic glue layer, a base layer, an acrylic pressure-sensitive adhesive layer, a silicon oil release layer and a bottom layer. The PET composite writing film is excellent in static resistance, aging resistance and scratch resistance, allows writings to be easy to maintain, easy to wipe and clean, free of fading and free of dust, and is widely applicable to various writing places such as schools, families and meeting places.

Description

The compound pad pasting of writing of a kind of PET

Technical field:

The present invention relates to the writing material technical field, relate in particular to the compound pad pasting of writing of a kind of PET.

Background technology:

In existing teaching, scientific research and daily life, usually use blackboard or writing whiteboard as writing carrier, but blackboard can only be used for writing of chalk, and dust is larger when writing and removing, unhealthful and write environment; Common writing whiteboard can only be used for writing of hydrate colour pen, and it is easily residual to write rear writing, and the wiping difficulty is large, and through write for a long time with wiping after, it is very smooth that its surface becomes, and is difficult to smoothness and writes; Other clipboard kind is a lot, comprises that the materials such as electronics, metal, pottery or other composite surface hardened layer form, but all exists complex structure, makes trouble, and cost is high, carries the shortcomings such as inconvenient.

Summary of the invention:

The purpose of this invention is to provide the compound pad pasting of writing of a kind of PET, this pad pasting can be attached to as using on the planes such as blackboard, common blank, electronic whiteboard and wall, difference according to the infield, can there be the surface of main body PET material layer light or the low light level to process (processing such as unglazed sand face), visual effect so that generation feels comfortably cool the beholder can be widely used in the various occasions of writing such as school, family, meeting.

Purpose of the present invention is achieved through the following technical solutions:

The compound pad pasting of writing of a kind of PET, it is characterized in that the described pad pasting of writing is formed by stacking successively by following structure sheaf: can write anti-zoned coating (1), clear PET structure sheaf (2), the synthetic glue-line (3) of pigmentable, substrate layer (4), acrylic pressure sensitive glue-line (5), silicone oil release layer (6) and bottom (7), described anti-zoned coating (1) thickness of writing is 2-3 μ m, clear PET structure sheaf (2) thickness is 10-200 μ m, and substrate layer (4) thickness is 50-200 μ m.

Preferred as technique scheme, described clear PET structure sheaf (2) thickness is 23-100 μ m.

Preferred as technique scheme, described substrate layer (4) be white PVC or PP synthetic paper.

Preferred as technique scheme, described substrate layer (4) thickness is 75-150 μ m.

Preferred as technique scheme, described bottom (7) is 80-200g/m ²Brown paper or thickness be the PET film of 10-75 μ m.

Preferred as technique scheme, described brown paper gram weight specification is 120-180 g/m ²

Preferred as technique scheme, the thickness of described PET film is 15-50 μ m.

Beneficial effect of the present invention is: this writes pad pasting is one to have the flexible membrane of straticulate structure, its agent structure is the PET material layer, its antistatic characteristic, anti-aging and scratch-proofness energy excellence make and write easily cleaning of easy maintenance, erasing, nondiscolouring, nondiscoloration, non-dust-staying.

Description of drawings:

The present invention is described further below in conjunction with accompanying drawing:

Fig. 1 is layer structure schematic diagram of the present invention.

The specific embodiment:

In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment, and this embodiment only is used for explaining the present invention, does not consist of the restriction to protection domain of the present invention.

The compound pad pasting of writing of this PET prepares according to following steps:

(1) choose thickness be the clear PET film of 23-100 μ m as structure sheaf (2), the PET film is two-sided corona;

(2) use the reticulate pattern coating machine, applicator roll is that the 160-200 line is write the surface that coating is applied to the PET film with UV, take energy as 250-300mj/cm ², spectral wavelength is that the light source of 340-420nm shines writing coating, and it is solidified, obtain 2-3 μ m thick write coating (1);

(3) choose a kind of rubber polymer of color-adjustable, add as requested mill base and the solvent of different colours, stir;

(4) choose a kind of PVC of white or PP synthetic paper as substrate layer (4), thickness is 75-150 μ m, deployed mill base is coated on a surface of substrate layer (4) with coating machine, be put in the baking oven and dry, form adhesive layer (3) on a surface of substrate layer (4) after the heat cure;

(5) with compounding machine fit into as a whole with the structure sheaf (2) of coated writing layer adhesive layer (3) coated in the substrate layer (4);

(6) upward coat acrylate pressure sensitive adhesive with coating machine at the substrate layer (4) of integral body, be put in the baking oven and dry, form adhesive layer (5) on a surface of substrate layer (4) after the heat cure;

(7) choose 120-180g/m ²Brown paper or thickness be the PET film of 15-50 μ m as bottom (7), be coated with last layer silicone oil with coating machine on (7) surfaces of bottom, be put in the baking oven and dry, form release layer (6) on a surface of bottom (7) after the heat cure;

(8) adhesive layer in the step 6 (5) and release layer (6) are fitted with compounding machine, obtain the compound pad pasting of writing of described PET.

Described PET is compound to write pad pasting as shown in Figure 1, is formed by stacking successively by following structure sheaf: can write anti-zoned coating (1), clear PET structure sheaf (2), the synthetic glue-line (3) of pigmentable, substrate layer (4), acrylic pressure sensitive glue-line (5), silicone oil release layer (6) and bottom (7).
