Abstract
The invention relates to a transfer basement film for use in the aluminum plating of gold and silver ornaments. The basement film is comprised of layers A, B and C which are formed by hot melting, coextrusion and bidirectional stretching, wherein the layer A is a surface layer; the layer B is a core layer; the layer C is a transfer layer; the layer A comprises 95.0 to 97.0 weight percent of PP and 3.0 to 5.0 weight percent of an antisticking agent; the layer B comprises 97.0 to 98.0 percent of PP and 2.0 to 3.0 percent of slipping agent; and the layer C comprises 95.0 to 97.0 percent of PP, 2.0 to 3.0 percent of antisticking agent and 1.0 to 2.0 percent of slipping agent. As the transfer layer, namely the layer C, of the BOPP is added with the slipping agent and the antisticking agent, the energy of the film surface of the layer is reduced and the film surface has a smaller color layer adhesive force than an aluminum layer, so the film surface is clean when stripped from the adhered aluminum layer and the aluminum layer and the color layer are transferred onto card paper completely. When the basement film is used in the manufacturing of gold and silver card paper, a process procedure of coating a stripping layer is not required. The base film can be repeatedly used for a plurality of times, greatly reduce cost, improve the rate of finished products and produce bright color and good effect.
Description
Technical field:
The present invention relates to a kind of three-layer co-extruded bidirectional stretching polypropylene film, be a kind of special BOPP film, this film has a special surface, and it can be aluminized equably, and this layer aluminium can be whole, transfer on the paperboard i.e. transfer basement film for use in aluminum plating of gold and silver ornaments intactly.
Background technology:
In the public place of entertainment, advertising sector, hotel and widely used colourful, the sparkling paperboard of handicraft industry, this paperboard is because be coated with the aluminium molecular layer of one deck 200～400A between chromatograph and the paper, under the irradiation of light, through reflection of light, refraction and the visual effect that forms.
This gold and silver decoration paper (being commonly referred to as the gold and silver paperboard) past of aluminizing is with common BOPET or BOPP film, on face, be coated with earlier one deck peel ply, be coated with the last layer chromatograph again, on chromatograph, aluminize, gluing on aluminium lamination is bonded together with paperboard then, and paperboard and basement membrane are peeled off, aluminium coated and chromatograph have just been transferred on the paperboard, and original basement membrane is bad again with abandoning because of scribbling absciss layer.
Summary of the invention:
The objective of the invention is to the improvement to existing transfer basement film for use in aluminum plating of gold and silver ornaments, make a surface of BOPP film have certain energy, this energy guarantees to coat equably chromatograph, can aluminize equably on the surface of chromatograph.But this energy (face is to the absorption of chromatograph) is less than the absorption of aluminium lamination to chromatograph, thereby face is clean when peeling off after the aluminium lamination coated with adhesive, and aluminium lamination is complete.
The present invention is made of the A layer that becomes one by hot melt, co-extrusion and biaxial tension, B layer and C layer, and wherein the A layer is a superficial layer, and the B layer is a sandwich layer, and the C layer is a transfer layer, and the material component weight proportion of each layer is:
A layer: PP 95.0～97.0%, antiplastering aid 3.0～5.0%;
B layer: PP 97.0～98.0%, slipping agent 2.0～3.0%;
C layer: PP 95.0～97.0%, antiplastering aid 2.0～3.0%, slipping agent 1.0～2.0%.
The present invention, employed raw material can domesticize, as the T38F of the available Hunan of PP (HOPP) petrochemical industry, the T36F of Maoming petrochemical industry etc., slipping agent can be moulded the SJ065 of emerging masterbatch Co., Ltd with the Foshan City, and antiplastering aid can be moulded the AB801 of emerging masterbatch Co., Ltd with the Foshan City.
The present invention, owing to pass through to add the way of slipping agent and antiplastering aid at the transfer layer (being the C layer) of BOPP, reduce the energy of this tunic face, guaranteeing to coat equably chromatograph, under the prerequisite that can aluminize equably on the surface of chromatograph, make face to the absorption of chromatograph less than the absorption of aluminium lamination to chromatograph, thereby face is clean when peeling off after the aluminium lamination coated with adhesive, aluminium lamination and chromatograph are intactly transferred on the paperboard.
The present invention, its production technology is similar to prior art: required various raw materials are entered A, B, three layers of extruder of C respectively after preparation, material melts plasticizing in extruder, enter die head after the homogenizing, three kinds of materials become three layers to extrude from the die head lip simultaneously in the die head internal conversion, on sharp cooling roll, cast the threeply diaphragm, diaphragm enters longitudinal stretching machine, longitudinal stretching is 4～6 times after preheating, drawn thin diaphragm to enter the cross directional stretch machine, further 8～10 times of cross directional stretch again after the heating, cooling then, enter trailer system, to film thickness measuring and sided corona treatment.The feedback information of the horizontal thickness measuring of film is to die head, and computer is adjusted the die head bolt automatically as calculated, to guarantee the even of film thickness.Through sided corona treatment, further after the cooling, film enters winder, is wound into semi-finished product film volume.The semi-finished product film carries out the physical property test, and Ageing Treatment cut into finished film after 48～72 hours, packed, dispatched from the factory.
Major advantage of the present invention:
When 1, making the gold and silver paperboard with the present invention, that uses when reducing BOPET in the past or BOPP film is coated with the absciss layer operation;
2, the special-purpose film of BOPP of the present invention can reduce cost greatly repeatedly with several times;
3, raw materials used can all production domesticization the, easily buying;
4, with this special-purpose film production gold and silver paperboard, the yield rate height: because of there not being the interference of peel ply, color is more bright-coloured, better effects if;
5, the present invention can use existing equipment fully, and production technology adjusts slightly and gets final product, and need not increase investment.
Description of drawings:
Fig. 1 is for utilizing the aluminize process schematic representation of paperboard of existing BOPP film production, promptly utilizes existing BOPP film A1 production to aluminize after the paperboard B, and the BOPP film is bad again with abandoning because of scribbling absciss layer.
Fig. 2 utilizes the aluminize process schematic representation of paperboard of BOPP film production of the present invention, promptly utilizes BOPP film A2 of the present invention production paperboard B that aluminizes, and can save and be coated with the absciss layer operation; Because the BOPP film A2 face after peeling off is clean, and aluminium lamination and chromatograph are intactly transferred on the paperboard, BOPP film A2 can use several times repeatedly simultaneously.
Among the figure, 1, BOPP basement membrane 2, absciss layer 3, chromatograph 4, aluminium coated 5, adhesive 6, paperboard A1, existing BOPP basement membrane A2, BOPP basement membrane B of the present invention, the paperboard of aluminizing.
