Abstract
A self-adhesive protective film characterized in that: the protective film with the self-adhesive property is sequentially arranged from top to bottom as follows: a release layer, a support layer and an adhesive layer; the release layer and the support layer are made of PE materials, and the release layer and the support layer are formed into a material base material layer; the adhesive layer is made of a co-extrusion adhesive blend matched with the performance of the plastic rice; the utility model discloses a protection film is from taking viscidity, and viscidity stability, protection film not only use for a long time not cull, can paste in addition not high plain noodles back of the body thing, is often used for from surfaces such as type membrane waste discharge, dull polish surface plastic board, sculpture shaping, stainless steel board, aluminum plate, and application scope is wide, excellent in use effect.
Description
Technical Field
The utility model relates to a from sticky protection film.
Background
The adhesive protective film coated with the acrylic glue and the electrostatic protective film without the adhesive are arranged on the market, the adhesive protective film coated with the acrylic glue has the adhesive property and can well adsorb the surface of a product, but as the using time is prolonged and the temperature and humidity of the environment change, acrylic acid molecules of liquid glue react with the surface of an object to be pasted, the adhesive property is unstable, and the adhesive residue risk phenomenon can occur; although the electrostatic protection film without viscosity avoids the risk of adhesive residue, the electrostatic protection film can not be stuck to the back stickers with non-high-gloss surfaces (such as release film waste discharge, frosted surface plastic plates, engraving molding, stainless steel plates, aluminum plates and the like).
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve prior art's problem, provide a from taking viscidity, can not appear the cull from taking viscidity protection film.
The technical scheme of the utility model: the protective film with the self-adhesive property is sequentially arranged from top to bottom as follows: a release layer, a support layer and an adhesive layer; the release layer and the support layer are made of PE materials, and the release layer and the support layer are formed into a material base material layer; the adhesive layer is made of a co-extruded adhesive blend with the performance matched with that of the plastic rice.
Further, the release layer is made of LDPE plastic rice; the support layer is made of LDPE and MLDPE plastic rice.
The utility model has the advantages that: the utility model discloses a protection film is from taking viscidity, and viscidity stability, protection film not only use for a long time not cull, can paste in addition not high plain noodles back of the body thing, is often used for from surfaces such as type membrane waste discharge, dull polish surface plastic board, sculpture shaping, stainless steel board, aluminum plate, and application scope is wide, excellent in use effect.

Fig. 1 is a structural diagram of the present invention.
Detailed Description
As shown in the figure: a self-adhesive protective film characterized in that: the protective film with the self-adhesive property is sequentially arranged from top to bottom as follows: a release layer 1, a support layer 2 and an adhesive layer 3; the release layer 1 and the support layer 2 are made of PE materials, and the release layer 1 and the support layer 2 are synthesized to be used as material base material layers; the adhesive layer 3 is made of a co-extrusion adhesive blend (commonly called modified rubber resin) matched with the performance of the plastic rice; the release layer 1 is made of LDPE plastic rice; the supporting layer 2 is made of LDPE and MLDPE plastic rice.
The protective film is prepared by a blow molding process, the adhesiveness of the protective film is stable, and the adhesiveness data is that the peel strength (standard stainless steel) at 180 ℃ is 8.6N/25mm (20 min. @25 ℃) and the peel strength (standard stainless steel) at 10.3N/25mm (7 days at @25 ℃) are attached; meanwhile, the adhesive layer of the protective film adopts a co-extrusion adhesive blend (commonly called modified rubber resin), so that the risk of adhesive residue is solved.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
