Abstract
The utility model relates to a kind of leather release liners based on film technique, and this paper is leaching membrane layer, polyolefin resin layer, release liners original paper layer and polyolefm film layer from top to bottom successively.Adopt the utility model, due to after polyolefin resin layer is added with polyvinyl alcohol as separation layer, both can improve paper substrate surface uniformity, strengthen paper substrate intensity, improve recycling number of times, paper substrate and leaching membrane layer bond strength can be improved again, prevent prestripping phenomenon from occurring; And the thermoplastic characteristics of leaching membrane layer material gives this paper good decorative pattern embossability, make the decorative pattern that is transferred on leather clear true to nature; In addition, polyolefm film layer can prevent from water suction from making moist occurring curling, avoids fluffing in use procedure, falls mao phenomenon and occur, improve the recycling number of times of release liners.
Description
Technical field
The utility model relates to a kind of leather release liners based on film technique.
Background technology
At present, leather release liners is a kind of special paper kind that prevents adhesion, and is transfer coated indispensable carrier material when producing polyurethane (PU) synthetic leather and polyvinyl chloride (PVC) artificial leather.Generally primarily of base paper, release coating two parts composition.Coating generally has concavo-convex pattern structure, impression decorative pattern thereon can be copied on synthetic leather and give synthetic leather decorative pattern attractive in appearance.But it is uneven to adopt the release liners surface manufactured in this way, cause the decorative pattern that impresses unintelligible above, and water suction is made moist and can be occurred curling, fluffs, falls hair, cause reusable number of times low, can not meet market demands in use procedure.
Summary of the invention
The purpose of this utility model be to provide can solve surface uneven, stamping is unintelligible, and release layer is easily peeled off, water suction make moist can occur curling, in use procedure fluff, fall hair, reuse a kind of leather release liners based on film technique of the low problem of number of times.
The technical scheme that the utility model is taked is: a kind of leather release liners based on film technique, it is characterized in that it is leaching membrane layer, polyolefin resin layer, release liners original paper layer and polyolefm film layer from top to bottom successively.
Described polyolefin resin layer is first by one or more mixing in polyvinyl resin, acrylic resin or Corvic, then is that 4 ~ 5 ︰ 1 mix in mass ratio with polyvinyl alcohol.
Described leaching membrane layer is to be coated on polyolefin resin layer by film after poly-4-methylpentene and polypropene blended granulation.
Described polyolefm film layer is one or more superpositions in polyethylene film, polypropylene film or polyvinyl chloride film.
Adopt the utility model, due to after polyolefin resin layer is added with polyvinyl alcohol as separation layer, both can improve paper substrate surface uniformity, strengthen paper substrate intensity, improve recycling number of times, paper substrate and leaching membrane layer bond strength can be improved again, prevent prestripping phenomenon from occurring; And the thermoplastic characteristics of leaching membrane layer material gives this paper good decorative pattern embossability, make the decorative pattern that is transferred on leather clear true to nature; In addition, polyolefm film layer can prevent from water suction from making moist occurring curling, avoids fluffing in use procedure, falls mao phenomenon and occur, improve the recycling number of times of release liners.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure, sequence number represents: release liners original paper layer 1, polyolefin resin layer 2, leaching membrane layer 3 and polyolefm film layer 4.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
With reference to Fig. 1, should be leaching membrane layer 3, polyolefin resin layer 2, release liners original paper layer 1 and polyolefm film layer 4 from top to bottom successively based on the leather release liners of film technique.Polyolefin resin layer 2 is wherein first by one or more mixing in polyvinyl resin, acrylic resin or Corvic, then is that 4 ~ 5 ︰ 1 mix in mass ratio with polyvinyl alcohol; Leaching membrane layer 3 is wherein to be coated on polyolefin resin layer by film extruder after poly-4-methylpentene (TPX) and polypropylene (PP) blended granulation; Polyolefm film layer 4 is wherein one or more superpositions in polyethylene film, polypropylene film or polyvinyl chloride film.
