Abstract
The utility model relates to a five-layer coextrusion release film, which is characterized by comprising an upper surface layer extended in two directions via coextrusion, an upper secondary surface layer, a core layer, a lower secondary surface layer and a lower surface layer, wherein the lamellar layout structure of the release film is sequentially that: the upper surface layer and the upper secondary surface layer are release layers, the core layer is a support layer, and the lower secondary surface layer and the lower surface layer are both release layers. The utility model has the advantages that the process is simplified, and the manufacturing cost is reduced; the release film has high tensile strength and good release effect; harmful materials and environment pollution are not generated in the production process; and the used release films can all be recycled to be made into other plastic products, energy is saved, the use cost of users is reduced, and the economic and social benefits are obvious.
Description
Technical field
The utility model belongs to the plastic sheeting technical field, particularly relates to a kind of five-layer co-squeezing mould release membrance.
Background technology
What be widely used in the market wilderness demand at present is glassine paper, and main component is a wood fibre, and efficient is low in the production, the customer using cost height; Above-mentioned glassine paper can't effective recycling after use, has not only caused the waste of resource but also has caused the pollution of environment.
Summary of the invention
But the utility model provides a kind of one-shot forming, hot strength height, energy-saving and cost-reducing and suitable industrial continuous production five-layer co-squeezing mould release membrance for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the five-layer co-squeezing mould release membrance, it is characterized in that: comprise upper epidermis through the coextrusion biaxial tension, last time top layer, sandwich layer, next top layer, the five-layer structure on top layer down, the layered arrangement structure of described mould release membrance is followed successively by: upper epidermis and last time the top layer be that release layer, sandwich layer are that supporting layer, next top layer and following top layer are release layer.
The utility model can also adopt following technical scheme:
Described upper epidermis, last time, the thickness on top layer, next top layer and following top layer was respectively 4～20% of mould release membrance gross thickness.
Advantage and the good effect that the utlity model has are: because each top layer of the present utility model, each time top layer and sandwich layer adopt a coextrusion mold, in manufacturing process, need not again compound, drench technology such as film, simplified processing technology, the reduction manufacturing cost; Make that the mould release membrance that processes has that hot strength height, release effect are good, advantage such as light weight, weatherability are good; All production processes can not produce any harmful substance, and non-environmental-pollution, the mould release membrance after the use can all reclaim makes other plastic products, but energy savings not only, but also reduced user's use cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, upper epidermis; 2, last time the top layer; 3, sandwich layer; 4, next top layer; 5, following top layer.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows;
See also Fig. 1, a kind of five-layer co-squeezing mould release membrance, comprise upper epidermis 1 through the coextrusion biaxial tension, last time top layer 2, sandwich layer 3, next top layer 4 and following top layer 5 five-layer structures, the layered arrangement structure of described mould release membrance is followed successively by: upper epidermis and last time the top layer be release layer, sandwich layer for the slipping agent that the HOPP resin adds an amount of 0.5-3% constitutes, next top layer and following top layer are release layer; Described upper epidermis 1 and last time top layer 2 be 100% release masterbatch; Sandwich layer 3 constitutes for the slipping agent that the HOPP resin adds an amount of 0.5-3%; Following top layer 4 and next top layer 5 are release layer, and its material adopts 100% release masterbatch.Described upper epidermis, last time the top layer, the thickness on top layer and next top layer is respectively the 4-20% of mould release membrance gross thickness down.
