Abstract
The invention relates to a casting compound type CPP aluminum-base plated film. The film consists of a layer A, a layer B and a layer C which form an integral body through hot melting, co-extrusion and biaxial tension, wherein the layer A is a heat-sealing layer, the layer B is a core layer, the layer C is an aluminized layer, and each layer comprises the following raw material components in percentage by weight: 95 percent of co-polypropylene and 5 percent of anti-sticking agent for the layer A; 100 percent of homo-polypropylene for the layer B; 75 to 93 percent of the co-polypropylene, 5 to 20 percent of reinforcing agent and 2 to 5 percent of the anti-sticking agent for the layer C, wherein the reinforcing agent is an ethylene methyl acrylate copolymer WH303. Because the formula of the layer C (the aluminized layer) is added with an aluminizing reinforcing agent, the adhesion force of an aluminized aluminum layer is greatly increased to ensure that the aluminum layer cannot be peeled off when the CPP aluminized film is in casting compounding. Besides, the casting compound type CPP aluminum-base plated film can be produced on the existing production line and can be produced in bulk without changing equipment.
Description
Technical field:
The present invention relates to a kind of three-layer co-extruded cast polypropylene film, mainly is the aluminium plating basement membrane that is used for as casting compound type.
Background technology:
At present, carry out vacuum aluminum-coated very generally with cast polypropylene film (being the CPP film), be widely used, its three layers of materials proportionings are as follows:
A layer hot sealing layer COPP 95%+ antiplastering aid 5%;
B layer sandwich layer COPP 100%;
C layer aluminium coated COPP 92～98%+ antiplastering aid 2～8%.
Carrying out dry type with this basement membrane aluminizes, CPP aluminizer after aluminizing is in that to carry out the dry type compound tense no problem with BOPP film or other film, but with PP or PE carry out curtain coating compound after, aluminium lamination is peeled off easily, have a strong impact on peculiar oxygen-barrier property of aluminizer and water vapor barrier property, lost the barriers function of aluminizer.
Summary of the invention:
The objective of the invention is to overcome the CPP aluminizer and carry out curtain coating compound tense aluminium lamination and peel off problem, just the low problem of the adhesive force of aluminium lamination on the CPP film.By changing the composition proportioning of C layer (aluminium coated), add a kind of reinforcing agent of aluminizing, the aluminium lamination adhesive force after aluminizing is increased greatly, guaranteed that the CPP aluminizer carries out curtain coating compound tense aluminium lamination and do not peel off.
Each layer raw material proportioning of the present invention is as follows:
A layer hot sealing layer COPP 95%, antiplastering aid 5%;
B layer sandwich layer HOPP 100%;
C layer aluminium coated COPP 75～93%, reinforcing agent 5～20%, antiplastering aid 2～5%.
The present invention, described reinforcing agent is ethylene-methyl methacrylate methyl terpolymer WH303.
The present invention owing in the prescription of C layer (aluminium coated), add a kind of reinforcing agent of aluminizing, increases the aluminium lamination adhesive force after aluminizing greatly, has guaranteed that the CPP aluminizer carries out curtain coating compound tense aluminium lamination and do not peel off.
Major advantage of the present invention is:
1, on existing production line, produces, need can not produce in a large number by change equipment;
2, process conditions change conveniently;
3, be used to aluminize, aluminium lamination adhesive force improves, and brings up to 2.5N/15mm by 1.0N/15mm;
4, aluminizer is used for curtain coating compound tense, not dealuminzation.
The specific embodiment:
Embodiment 1: casting compound type CPP aluminum-base plated film, and each layer raw and auxiliary material weight ratio is:
A layer COPP 95%, antiplastering aid 5%,
B layer HOPP 100%,
C layer COPP 93%, reinforcing agent 5%, antiplastering aid 2%.
Present embodiment can carry out on existing C PP production line, must reforming equipment, also needn't change existing production technology, and by the basement membrane of its production, through the processing of aluminizing, its aluminium lamination adhesive force reaches 1.2N/15mm.
Embodiment 2: on the basis of embodiment 1, other conditions are constant, only adjust C layer proportioning: COPP 87%, reinforcing agent 10%, antiplastering aid 3%, its aluminium lamination adhesive force reaches 1.8N/15mm.
Embodiment 3: on the basis of embodiment 1, other conditions are constant, only adjust C layer proportioning: COPP 81%, reinforcing agent 15%, antiplastering aid 4%, its aluminium lamination adhesive force reaches 2.1N/15mm.
Embodiment 4: on the basis of embodiment 1, other conditions are constant, only adjust C layer proportioning: COPP 75%, reinforcing agent 20%, antiplastering aid 5%, its aluminium lamination adhesive force reaches 2.5N/15mm.
When reinforcing agent surpasses 20%, though aluminium lamination adhesive force also along with increase, the other technologies performance of basement membrane descends, and generally is controlled at below 20%.
Embodiment 5: a kind of casting compound type CPP aluminum-base plated film, constitute by the A layer that becomes one by hot melt, co-extrusion and biaxial tension, B layer and C layer, wherein the A layer is a hot sealing layer, the B layer is a sandwich layer, the C layer is an aluminium coated, the thickness of A layer is 4～5 μ m, and the thickness of B layer is 15～17 μ m, and the thickness of C layer is 4～5 μ m.Each layer raw and auxiliary material weight proportion can be selected a kind of among embodiment 1～embodiment 4 for use.
Raw and auxiliary material of the present invention can be provided by following company:
Antiplastering aid is provided by Belgian Shu Er Man, and product type is: ABVT19NSC, or mould emerging masterbatch Co., Ltd by the Foshan City and provide, product type is: AB818-5SC;
The reinforcing agent of aluminizing is ethylene-methyl methacrylate methyl terpolymer WH303, is provided by day one's own department or unit friend Co., Ltd..
