Abstract
The utility model discloses a strippable rubber membrane which comprises a non anti-sticking layer, a middle layer and an anti-sticking layer successively from top to bottom. The layers are pressed and composited through an extruder, the non anti-sticking layer and the middle layer are made of polyolefin, and embossed patterns are arranged on surfaces of the non anti-sticking layer and the anti-sticking layer and are convex or concave portions. As the structure is arranged, the strippable rubber membrane is simple in structure and convenient to use, slipping agents of erucyl amide, oleamide or the like and opening agents of calcium carbonate, silica, talcum powder or the like are added in the anti-sticking layer, so that the slipping agents and the opening agents can reduce direct contact area of membranes and rubber, and accordingly, a three-layer co-extrusion structure of the strippable rubber membrane can maintains strippable properties constantly in a rubber packaging process.
Description
Technical field
The utility model relates to easily peels off rubber membrane.
Background technology
Common polyolefin film has good heat sealability and toughness, can play certain protective role to the product of needs packing.But carry out good design as polyolefin film not being formed mechanism, when package temperature is higher than 80 degrees centigrade rubber, will produce the bonding phenomenon, make troubles to work, also can reduce operating efficiency simultaneously.
Use the film of high melting-point polyolefins production can overcome the problem that bonds under the high temperature, but ordinary rubber packing instructions film DSC fusing point is lower than 110 degrees centigrade, so can not use high melting-point polyolefins to produce this product.
In view of this, the inventor has this case to produce for the defects further investigation of rubber membrane in the prior art then.
The utility model content
In order to overcome above shortcomings part in the prior art, the purpose of this utility model is to solve uses the polyolefin film package temperature to be higher than 80 degrees centigrade rubber, and the problem of use polyolefin film long preservation rubber, be lower than 110 degree to preparing a kind of DSC fusing point, can possess again the polyolefin co-extrusion film that the bonding phenomenon does not occur with rubber.
In order to reach above-mentioned purpose, the utility model adopts following concrete technical scheme: easily peel off rubber membrane, comprise from top to bottom successively by non-adherent layer, middle level and adherent layer, each layer forms by the extruder extrusion cladding, wherein non-adherent layer and middle level are that polyolefin is made, the surface of described non-adherent layer and adherent layer is provided with embossing, and embossing is protuberance or recess.
Compared with prior art, the utlity model has following outstanding advantages and effect: owing to being provided with above structure, it is simple in structure that this easily peels off rubber membrane, easy to use, and added slipping agent at adherent layer, erucyl amide or oleamide etc., and opening agent, the direct contact surface that calcium carbonate or silica or talcum powder etc., these slipping agents and opening and making reduce film and rubber amasss, therefore, so that three-layer co-extruded structure of the present utility model remains easy fissility when packing rubber.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figure 1, easily peel off rubber membrane, comprise from top to bottom successively by non-adherent layer 1, middle level 2 and adherent layer 3, each layer forms by the extruder extrusion cladding, wherein non-adherent layer 1 and middle level 2 make for polyolefin, the surface of described non-adherent layer 1 and adherent layer 3 is provided with embossing, embossing is protuberance or recess, it is simple in structure that this easily peels off rubber membrane, easy to use, and added slipping agent at adherent layer, erucyl amide or oleamide etc., and opening agent, calcium carbonate or silica or talcum powder etc., these slipping agents and opening and can make that to reduce film long-pending with the direct contact surface of rubber, therefore, so that three-layer co-extruded structure of the present utility model remains easy fissility when packing rubber.
The utility model is made flow process: by weight percentage polyvinyl resin and polyvinyl acetate are carried out the arbitrary proportion blend, drop into extruder middle level or non-adherent layer.As base material, sneak into therein by weight percentage erucyl amide 0.5-5%, calcium carbonate 1%-10% by the polyethylene of preparation arbitrary proportion mixing and polyvinyl acetate.Through extruder fused materials is clamp-oned inflation film manufacturing machine or slobbering machine die head, cooling and shaping then, non-adherent layer carries out sided corona treatment, deburring, rolling namely obtains the utility model film article.
It should be noted that at last: above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
