Abstract
The invention discloses an aluminum plating non-stretching polypropylene film with aluminum layer peeling intensity enhancement type, which is composited by a heat sealing layer, a sandwich layer and a corona layer; wherein, the heat sealing layer uses ternary polymerization polypropylene; the sandwich layer uses HOPP; the corona layer uses the blended materials of the ternary polymerization polypropylene and ethylene/methylmethacrylate. The invention also discloses a preparation method of the aluminum plating non-stretching polypropylene film with the aluminum layer peeling intensity enhancement type. The aluminum plating non-stretching polypropylene film of aluminum layer peeling intensity enhancement type draws into a surface active material ethylene/methylmethacrylate in the corona layer, thus increasing the adsorption capability of the corona layer on the aluminum layer and having high aluminum layer peeling intensity performance which can not be exceeded by the common aluminum plating non-stretching polypropylene film.
Description
Technical field:
The present invention relates to a kind of polypropylene screen and preparation method thereof, relate in particular to a kind of un-stretched polypropylene film and preparation method thereof.
Background technology:
Along with the birth of un-stretched polypropylene film (CPP), rigidity, high transparent, high heat-sealing strength that CPP film product is had, and the wide characteristic of the range of work replaces the status of polyethylene film (PE) aspect the heat-sealing bag day by day.
Portioned product is polyethylene film/molten polyethylene film/bidirectional stretching polypropylene film (biaxially oriented polyester film) in the market, and promptly the molten PE/BOPP (BOPET) of PE/ carries out compound, color printing.Domestic is to adopt dry type compound substantially, promptly adopts glue compound, and this compound working procedure has the advantage that compound fastness is strong and be difficult for peeling off, but needs to adopt the coating of polyurethane, and certain organic survival is arranged, and food sanitation safe is had certain influence.What now common on the market aluminized grade un-stretched polypropylene film (MCPP) is to be made by polypropylene casting, its structure is ternary polymerized polypropylene/HOPP/ternary polymerized polypropylene, be CO-PP/HO-PP/CO-PP, its advantage is high heat-sealing strength, low heat-sealing temperature, brightness better reaches good characteristics such as barrier property, is the packaging product commonly used of food.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of aluminium lamination peel strength enhancement mode grade un-stretched polypropylene film of aluminizing, with the aluminize peel strength of back and aluminium lamination of raising.
The technical problem that the present invention also will solve provides the above-mentioned aluminium lamination peel strength enhancement mode grade preparation method of un-stretched polypropylene film that aluminizes.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
A kind of aluminium lamination peel strength enhancement mode grade un-stretched polypropylene film of aluminizing, it is composited for three layers by hot sealing layer, sandwich layer and corona layer, wherein hot sealing layer adopts the ternary polymerized polypropylene material, sandwich layer adopts HOPP, and the corona layer adopts ternary polymerized polypropylene and ethylene-methyl methacrylate methyl terpolymer intermingling material.Promptly adopt CO-PP/HO-PP/ (CO-PP+EMMA) three-layer composite structure, the floor height of three-decker is than being 1:3:1.
Wherein, the mixing ratio of ternary polymerized polypropylene and ethylene-methyl methacrylate methyl terpolymer is 3～4:1.
Thinking of the present invention is the polypropylene film of the three-layer composite structure made for existing CO-PP/HO-PP/CO-PP material, and adding ethylene-methyl methacrylate methyl terpolymer (EMMA) carries out modification among CO-PP (corona layer).
Ethylene-methyl methacrylate methyl terpolymer, English contract and claim EMMA, thereby are to obtain EMMA by connect the skill methyl methacrylate on the PE main chain.
The EMMA molecular structure is as follows:
Wherein m gets any natural number, and n gets any natural number.(m, the n span is between 200～2000).
The ester class group that on the ethylene-propylene main chain, connect skill among the EMMA, so good Combination is arranged with the ternary atactic copolymerized polypropene, and extrusion temperature is comparatively approaching, also have good low-temperature flexibility and excellent environmental stress crack resistance, easy involution, the involution temperature is lower than vinyl-vinyl acetate copolymer (EVA), heat sealable wide ranges, heat-sealing is better strong, and heat endurance is better than EVA, is not easy to take place crosslinked and degraded.And help improving its gluing to metal forming, paper, aluminium and other metals and nonmetallic materials along the random ester group group of arranging on the main chain.So EMMA has the fusion character good with the ternary polypropylene, can blend use, simultaneously aluminium is had good cohesive force.
The above-mentioned aluminium lamination peel strength enhancement mode grade preparation method of un-stretched polypropylene film that aluminizes is as follows:
(1) ternary polymerized polypropylene is dropped into extruder A, HOPP is dropped into extruder B, ternary polymerized polypropylene and ethylene-methyl methacrylate methyl terpolymer are mixed the back with the weight ratio of 3～4:1 drop into extruder C, respectively heating and melting;
(2) A, B, three extruders of C are the film shape simultaneously through T pattern head and extrude continuously, and the flow-rate ratio that control is extruded is 1:3:1, cooling forming.
Beneficial effect: the aluminium lamination peel strength enhancement mode of the present invention grade un-stretched polypropylene film of aluminizing has been introduced surface active material (EMMA) in the corona layer, strengthened the adsorption capacity of corona layer to aluminium lamination, therefore has the unrivaled high aluminium lamination peel strength performance of common MCPP product, peel strength 〉=1.0N/15mm (common MCPP is at 0.3-0.5N/15mm), effect is remarkable, in compound with extruding of polyvinyl resin (PE) bonding strength is preferably arranged thereby satisfy after the CPP film is aluminized.
Description of drawings
Accompanying drawing is the aluminium lamination peel strength enhancement mode of the present invention grade generalized section of un-stretched polypropylene film of aluminizing.
The specific embodiment
The present invention is further described below in conjunction with accompanying drawing.
As shown in the figure, the aluminium lamination peel strength enhancement mode of the present invention grade un-stretched polypropylene film of aluminizing is to be made of hot sealing layer (1), sandwich layer (2) and corona layer (3).Wherein hot sealing layer adopts ternary polymerized polypropylene, and sandwich layer adopts HOPP, and the corona layer adopts ternary polymerized polypropylene and the ethylene-methyl methacrylate methyl terpolymer intermingling material of 3:1 by weight.Described hot sealing layer, sandwich layer and corona layer three's floor height is than being 1:3:1.
Production method is as follows:
1, ternary polymerized polypropylene is dropped into extruder A, HOPP is dropped into extruder B, ternary polymerized polypropylene and ethylene-methyl methacrylate methyl terpolymer are mixed the back with the weight ratio of 3:1 drop into extruder C, respectively heating and melting;
2, A, B, three extruders of C are the film shape simultaneously through T pattern head and extrude continuously, and the flow-rate ratio that control is extruded is 1:3:1, cooling forming.
