Description
Technical field
The utility model relates to the multilayer furniture film comprised containing polyether polyols with reduced unsaturation layer.
Background technology
In the past, to produce and material cost is favourable, process simple and easy, stable chemical performance, the high grade of transparency, excellent mar proof and high resiliency make polyvinyl chloride (PVC) become main synthesis basic material for floor covering, wall panel and furniture film.
Such as have been found that PVC film has multiple application in the production of cheap furniture surface, it such as partly uses timber and partly uses the ply of paper or rete that it are printed with wood pattern to copy wood surface.
Its shortcoming such as PVC counteracts its advantage to the impact of environment and character when burned, and this impels the alternative materials found as the substitute of PVC.
Propose many polymer material as an alternative, such as polyolefin, polyamide, polyurethane, polystyrene, polyester and their copolymer and derivative; Their are all same cheap and easily produce, but they are inferior to PVC in mechanical performance and mar proof.The visible side faces of antique traditional furniture film uses layer of varnish or resin (such as melmac) layer to reinforce usually.Because higher cost of material and processing cost and LCA deterioration, which increase the cost of composite membrane.Have also been described the composite attempted combining as the polyolefinic advantage of cheapness of substrate material with the high mechanical performance of polar polymer.Up to now, these effort the security guaranteed between layer and durability interrelated in encounter difficulty, if possible, do not use adhesive and be provided for producing the efficient of composite and continuous print method, and implementing this production method makes the outward appearance of multilayer film meet the highest aesthetic demands, and can as the substitute on nature material such as wood surface or cork surface.DE 29522366 U1 describes the Multilayer plastic film for furniture or furniture part, and it also comprises polyolefin layer among other things.Calender or extruder is used to produce this Multilayer plastic film.DE 102012103016 A1 describes a kind of film laminar composite comprising at least two plastic foils, described two plastic foils comprise base material film and functional membrane, wherein functional membrane be arranged on base material film side on and can be printed thereon, base material film is the polyolefin film of preferably having painted, and functional membrane is made up of thermoplastic polyurethane.These laminar composites are produced by adhesive lamination or heat lamination clearly, and recommended for Floor Industry, furniture industry, indoor decoration industry and/or outdoor decoration industry.DE 10309917 Al describe a kind of co-extrusion, the furniture film of at least triple laminate, core layer is dyeed and two side is all covered by the cover layer that two are such as made up of PET equably wherein.The laminar composite of co-extrusion by the functional membrane connected by one or more articulamentum and base material film do not mentioned by these files.
Need the furniture film of co-extrusion, this is because the combination of its overall enhanced between layers and composite are to the mechanical of the enhancing of peeling off and tear.Because the incompatibility of thermoplastic, so contain containing the furniture film of functional polyurethane layer with such as containing polyolefin and need to use adhesive or connector with the inconsistent substrate layer of functional layer.But, also do not describe and use extra co-extrusion articulamentum to carry out co-extrusion two this layers.In expert circles, adhere to that viewpoint is so far, co-extrusion eliminates the possibility using connector.Such as, warn in DE102012008401 Al and say, in coextrusion method, two directly can be connected and do not use connector.
