CN103373145A - Writing PVC (polyvinyl chloride) film and method for manufacturing same - Google Patents

Abstract

The invention discloses a writing PVC (polyvinyl chloride) film and a method for manufacturing the same. The film sequentially comprises a writable scribble-resistant layer, an embossed PVC layer, an acrylic acid pressure-sensitive adhesive layer, a silicone oil release layer and a base layer from top to bottom. The method for manufacturing the writing PVC film includes drawing a PVC matt thin film by the aid of a calender and forming granular protrusions with the sizes of 5-100 micrometers on the thin film by the aid of the surface of an embossing roller; coating the scribble-resistant layer on a matt surface of the PVC thin film; manufacturing the acrylic acid pressure-sensitive adhesive layer on a glossy surface of the PVC thin film; selecting kraft paper or a PET (polyethylene terephthalate) thin film as the base layer and manufacturing the release layer on a surface of the base layer; laminating the acrylic acid pressure-sensitive adhesive layer with the release layer by the aid of a compound machine to obtain the writing PVC film. The writing PVC film and the method have the advantages that the surface of the film is high in scribble resistance, the writing PVC film is portable and reusable, the method is simple in operation, and the cost is low.

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

A kind of PVC pad pasting of writing is characterized in that described pad pasting comprises successively from top to bottom can write anti-zoned coating, embossing PVC layer, acrylic pressure sensitive glue-line, silicone oil release layer and bottom; The one side of embossing PVC layer is the mute face film of PVC, and film surface has the strong projection of the particle of 5-100 μ m; Bottom is brown paper or PET film.

A kind of preparation method who writes the PVC pad pasting may further comprise the steps:

(1) the PVC pellet of allotment different colours is pulled out the mute face film of PVC with calender, and film produces the strong projection of particle of 5-100 μ m by the knurling rolls surface;

(2) coat anti-zoned coating at the mute face of PVC film;

(3) PVC film light face is coated acrylate pressure sensitive adhesive, be put in the baking oven and dry, form the acrylic pressure sensitive glue-line after the heat cure;

(4) choose brown paper or PET film as bottom, be coated with last layer silicone oil with coating machine on surface of bottom, be put in the baking oven and dry, form release layer after the heat cure;

(5) acrylic pressure sensitive glue-line and release layer are fitted with compounding machine, obtain the described PVC of writing pad pasting.

Beneficial effect of the present invention is: apply at main body PVC film surface and can write anti-zoned coating, make writing surface have good anti-aging and scratch-proofness energy, greatly prolong service life, this pad pasting can be attached on the kinds of surface, therefore has fine property easy to use, the preparation method is simple to operate, and is with low cost, is conducive to Technique Popularizing and uses.
