Description
What the present invention relates to is the new method that a kind of metal coating is transferred to paper surface.
Adopt Vacuum Coating method, form aluminium plating membrane, transfer to the production technology of paper surface then on the surface of polyolefin-type plastic sheeting.The cost of material is low for it, and presentation quality is good, more and more is subjected to the order of advising of packaging industry, day by day development.As the transferable Vacuum Aluminizing Technology of U.S. Yi Litian company, it forms the transparent resin layer that can be rich in demoulding in carrier surface coating, and drying is vacuum aluminum-coated then, adds bonding agent and carries out compoundly, carries out dried again, peels off carrier film to reach.But this method must be on carrier film surface coating remover earlier, vacuum aluminum-coated compound after so that peel off carrier film, cause complex process, the cost height.86105006 production technology of aluminium-plating paper with transfering for another example, this technology has been cancelled remover, and is directly vacuum aluminum-coated on base material film, makes bonding agent with aluminizer and paper compound sticking together with the heatmeltable resin.Though this technology has been saved remover, but the heatmeltable adhesive is not strong to the aluminium plating membrane diffusion permeability, part aluminium molecule remains on the base material, next is the restriction that stability is subjected to substrate resin, general heatmeltable resin heat endurance is not high, is difficult to shift the aluminium molecule fully, makes base material film peel off difficulty, and will be equipped with corresponding operating equipment, thereby invest more.
The present invention is directed to above-mentioned deficiency, propose a kind of method of metal film-plating paper, reduce production costs, improve the quality of products, enlarge the purpose of product range of application to reach.
Technical scheme of the present invention is to consider like this: select the specific film of polyolefin for use, according to the characteristic that the plated film layer is easily peeled off, get involved this metal-plated rete and paper surface with bonding force adhesive strong, that film forming is better, solidification temperature is lower, by compound, then the bonding paper of polyolefin-type film and metal film is separated, just form the high level metal film of the level and smooth light of one deck on the paper surface, thereby finish the production metal film-plating paper.
Polyolefin certain thin films such as Biaxially oriented polypropylene (BOPP) film, in the technology of making film, improve surface smoothness, do not need the surface (make film producer can reduce production costs, electric energy) of Corona discharge Treatment film, wetting tension is controlled in 35 dynes per centimeter.Just cancel the transparent resin layer that coating is rich in demoulding, thereby reduce batching, stirring together; The operation of one coating and oven dry.As body paper, available general in, low-grade paper.
When the research adhesive, the present invention selects for use adhesive that polyurethane, acrylate, phenolic resins, epoxy resin, water-based adhesive are arranged; Also use EVA latex, polyamide and plant containing natural macromolecule and animal polymer binder.Find in the test that these thermosetting resins and thermosol have performances such as resistance to oxidation, anti-ozone, heat-resisting, cold-resistant, oil resistant.Particularly polyurethane and modification acrylate and water-based adhesive have good compatibility to bonded object such as paper, metal, plastics, fabric, rubber etc. when bonding.It can bonding representational object, be widely used in the bonding of light packaging material, the manufacturing of composite, the lamination of fabric.
Show after deliberation: vacuum coating surface adheres to and is not very firm on the carrier film, when carrier metal film and paper because of getting involved adhesive, it is easy to flow, bonded body surface rough partially filled obtain comparatively smooth, and fully soak into the surface of adherend, after heating, solidify.(learn that by thermodynamic analysis the contact angle of liquid on the surface of solids is more little,, be easy to bonding the easy more infiltration of the surface of solids.) because of the adhesive got involved during expanded by heating, easily makes metal film get loose in compounding machine, the metallic diaphragm that gets loose fits together with paper under the adhesion of adhesive, through cooling and shaping, the metallic diaphragm on the carrier film just is bonded on the paper firmly with adhesive.Again carrier film is separated, just can obtain the metal film paper level and smooth, that brightness is fabulous.Through test, the present invention not only can transfer to the metallic diaphragm on the carrier film on the paper, but can also transfer on the smooth and fine and close nonmetal sheet material of rolling, thereby has enlarged range of application of the present invention.
The present invention implements like this.At first will select thickness for use is that the BOPP film of 20 to 100 μ m is a carrier film, and without processing such as coronas, in the vacuum coating equipment of directly packing into, the evaporation metal rete is 300 to 600 , and the material of plated film is metals such as aluminium, copper silver.Then carrier film behind the plated film and paper are introduced respectively in the compounding machine, between carrier film and paper, are got involved adhesive, make the carrier film of metal-plated membrane layer and paper fit mutually, bonding, peel off carrier film then, make metal film-plating paper.
The adhesive of resinoid that the present invention adopts such as polyurethane series, this adhesive does not finish in its reaction of solvent evaporation back, still has flowability.Then can make heat-resisting, water-fast, oil resistant, cold-resistant, resistance to oxidation, soft tough and tensile film by curing reaction.After compound object is batched, still proceed curing reaction at normal temperatures.Polyurethane is divided into bi-component and one pack system; The first component is polyols such as the polyester that contains terminal hydroxy group, polyethers, or with isocyanate-modified hydroxyl telechelic polyester, polyethers.The second component is a polyisocyanates or with the isocyanate-terminated performed polymer of terminal hydroxy group compound (polyester, polyethers etc.) modification.Allocate according to certain ratio during use.The assembly of first, second is than being first: second=100: 5～15.
As the trade mark is " anchor 101 ", forms (weight portion) to be:
Terminal hydroxy group linear polyesters polyurethane acetone soln is 100;
Modification toluene di-isocyanate(TDI) ethyl acetate solution is 10.
For quickening to solidify, improve performance, can add 0.1～0.3% triethanol ammonium or diethyl ammonium ethanol.
The water-based adhesive of the present invention's development is applicable on the hygroscopic compound package material.Be two kinds of water-dispersible adhesive prescriptions below:
