Abstract
A cast polypropylene for compositing paper and plastic is provided; the straight laminating is formed by co-extruding and casting a surface layer, a core layer and a thermal sensitive functional layer; and the core layer is positioned between the surface layer and the a thermal sensitive functional layer. In the design of the utility model, the paper-plastic thermal composite strength is too lower to be layered, while the thickness of the thermal sensitive functional layer is less than 5% of the thickness of the total membrane, so that the paper-plastic is not easily composited firmly via researching and testing; the adhesion of the functional layer causes the thermal sensitive functional layer to adhere the roller in hot pressing while the thickness of the thermal sensitive functional layer exceeds 30% of the thickness of the total membrane, so that the process becomes difficult. The dropping of the anti-adhesion agent influences the anti-adhesion effects while the thickness of the anti-adhesion layer of the surface layer is less than 5% of the total thickness; and the haze and the transparency of the product are influenced while the thickness of the anti-adhesion layer of the surface layer exceeds 20% of the total thickness.
Description
Technical field
The utility model relates to a kind of polypropylene film, and it is compound with cast polypropylene film again directly to relate to a kind of paper-mould.
Background technology
Being applied at present paper-mould in the industry, compound main first kind of mode adopts wet type compound through following several kinds of modes, and this complex method need be used a large amount of solvents, and this solvent is bigger to the pollution of environment; Second kind is that dry type is compound, promptly on paper, is coated with one deck adhesive, carries out compound through heating again; The third method is to drench the multiple low-viscosity ethylene-vinyl acetate copolymer of one deck on the polypropylene film surface, and then is combined with each other with paper.But no matter be that wet type is compound, dry type is compound or it is multiple compound to drench; All mean at compound tense and need increase one procedure; Not only improved production cost, and too much use adhesive and solvent all can produce bigger injury to environment and human body, and adhesive is because oxidation and flavescence gradually in the use; Thereby influenced the outward appearance of paper combination product, reduced service life.
The no glue composite membrane of domestic corporation's development at present generally is to adopt polypropylene bidirection drawing technology to make; As BOPP do not have the glue composite membrane promptly be one of them than successful story, yet the mode through cast polypropylene make no glue composite membrane or directly again film be used for paper-mould the still manque application of no glue complex technique.It mainly is the right restriction of production equipment, process conditions owing to casting technique and stretch processes, and not as the thin thickness of stretch processes, deflection and heat resistance are also not as biaxially oriented film as the thickness that casting technique is produced film.
Summary of the invention
It is compound with cast polypropylene film again directly that the purpose of the utility model provides a kind of paper-mould.Can't be to solve prior art through the excellent no glue composite membrane of the mode obtained performance of cast polypropylene or the problem of film again directly.
For solving the problems of the technologies described above, the technical scheme of the utility model is following: a kind of paper-mould the compound cast polypropylene of using, and said straight film is again formed by top layer, sandwich layer, temperature-sensitive functional layer coextrusion casting, and its center core layer is between top layer, temperature-sensitive functional layer.
As preferably, said temperature-sensitive functional layer thickness accounts for the 10%-25% of gross thickness, and said skin depth accounts for the 5%-15% of gross thickness.
Its mesexine adopts the higher relatively isotactic polypropylene of melting temperature, the synthetic silica of 2000ppm, and synthetic silica is to have done carrier with polypropylene in advance to have processed polypropylene anti masterbatch, and the content of synthetic silica is 10% in the anti masterbatch.
Its center core layer adopts 60% isotactic polypropylene, 20% polypropylene copolymer, 10% vinylacetate, the glycerin monostearate of 2000ppm, and wherein glycerin monostearate is to do carrier with polypropylene in advance to have processed polypropylene antistatic mother material equally.
Wherein the temperature-sensitive functional layer is the maleic anhydride grafts that contains 20% polypropylene copolymer, 20% ethylene-butene copolymer, 40% ethylene-butene copolymer, 20% vinylacetate.
In above-mentioned prescription design, top layer and sandwich layer are main with the higher isotactic polypropylene of heat resistance, and copolymer that the temperature-sensitive functional layer is then low with fusing point, viscosity is high and graft are main.In order to improve the interlayer adhesion of temperature-sensitive functional layer and sandwich layer, through add the polypropylene copolymer of certain content simultaneously in sandwich layer and temperature-sensitive functional layer, this copolymer and ethylene butene analog copolymer have certain compatibility, with polypropylene compatibility are preferably arranged also.In order to improve the low temperature adhesiveness of temperature-sensitive functional layer; Through adding hydrogenated petroleum resin; This material has good tackifying, compatibility, heat endurance and photostability; Also can improve the adhesive property of adhesive simultaneously, make film adhesiveness and permeance property to paper material when hot pressing improve greatly.
In the design of the utility model, through developing in many ways and test, when the thickness of temperature-sensitive functional layer accounts for total film thickness less than 5% the time, can be because paper-mould that hot combined strength bination is too low to cause layering, be difficult to compound firm; And surpass 30% when temperature-sensitive functional layer thickness accounts for total film thickness, can make owing to the viscosity of functional layer to become difficult and cause processing by temperature-sensitive functional layer roll banding when hot pressing.When top layer antiblocking layers thickness accounts for gross thickness less than 5% the time, can be owing to coming off of anti-blocking agent influences preventing adhesiving effect, and when its thickness above 20%, can the mist degree and the transparency of product be exerted an influence again.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment, the marrow of the utility model is done specifying further.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Fig. 1 is the structural representation of the utility model.This cast polypropylene is directly answered film and is comprised top layer 1, sandwich layer 2 and temperature-sensitive functional layer 3, and its center core layer 2 is between top layer 1, temperature-sensitive functional layer 3.
One of them example is following: overall film thickness is 20 μ m, and wherein skin depth is 3 μ m, and core layer thickness is 12 μ m, and temperature-sensitive functional layer thickness is 5 μ m.
At the paper of the utility model-mould in the compound practical implementation process, the heating-up temperature of version roller is 80-100 ℃, clamp time 0.5-2s, and concrete technology can be regulated according to actual process.
