Abstract
The utility model relates to the technical field of TPU (Thermoplastic polyurethanes) products, in particular to a multilayer TPU joint film. The multilayer TPU joint film comprises at least two different TPU film layers, wherein the two TPU film layers with different characteristics are stuck to each other through glue or are jointed together in a hot pressing manner, so that the performances of a TPU film such as elasticity, toughness, wearing resistance and the like can be improved, a series of physical properties such as cracking, fracture, no leak prevention and the like are not easy to be caused, and the performance of the jointed TPU film can be more excellent.
Description
Technical field
The utility model relates to the TPU product technical field, relates in particular to a kind of multilayer TPU attaching film.
Background technology
The TPU film is a thermoplastic polyurethane, and the branch of polyester-type and polyether-type is arranged, and is used widely in fields such as commodity, sports goods, toy, ornament materials, and halogen-free flameproof TPU film can also replace flexible PVC to satisfy the environmental requirement in more and more fields.Yet, the TPU film of existing, single performance, performances such as its elasticity, toughness, wearability, cold resistance all can not satisfy the requirement of specialities, also are easy to generate be full of cracks, break, other a series of rerum naturas such as not leakproof.
Summary of the invention
The purpose of the utility model is to the deficiency of prior art a kind of multilayer TPU attaching film to be provided, and can improve the performances such as elasticity, toughness, wearability of TPU film, makes it be difficult for producing be full of cracks, break and other a series of rerum naturas such as not leakproof.
For realizing above-mentioned purpose, the utility model adopts following technical scheme: a kind of multilayer TPU attaching film, and it comprises two-layer at least TPU thin layer inequality, described two-layer at least TPU thin layer pastes through glue or hot pressing mode fits together.
It comprises three layers of TPU thin layer.
It comprises four layers of TPU thin layer.
Said TPU thin layer is provided with embossing or printed layers.
The utility model beneficial effect is: the described a kind of multilayer TPU attaching film of the utility model; The TPU thin layer of multilayer different qualities is fit together through glue stickup or hot pressing mode; Can improve the performance such as elasticity, toughness, wearability of TPU film; Make it be difficult for produce be full of cracks, break and other a series of rerum naturas such as not leakproof, make the TPU film performance after the applying more excellent.
Description of drawings
Fig. 1 is that the utility model is the production sketch map of the two-layer TPU thin layer hot pressing mode when fitting.
Fig. 2 is that the utility model is the production sketch map of the two-layer TPU thin layer glue adhesive type when fitting.
Fig. 3 is that the utility model is the two-layer TPU thin layer production sketch map when fitting.
Fig. 4 is that the utility model is that when fitting another of two-layer TPU thin layer produced sketch map.
Fig. 5 is that the utility model is three layers of TPU thin layer production sketch mapes when fitting.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The said a kind of multilayer TPU attaching film of the utility model; It comprises two-layer at least (different qualities) TPU thin layer inequality; Described two-layer at least TPU thin layer pastes through glue or hot pressing mode fits together, and further, said TPU thin layer is provided with embossing or printed layers.Preferably, said TPU thin layer can for two-layer, three layers, four layers, five layers etc., specifically can decide by actual needs.Wherein, said two-layer at least TPU thin layer inequality, their thickness, color, decorative pattern, soft durometer, optical haze are all inequality.
The production technology of said a kind of multilayer TPU attaching film may further comprise the steps: steps A, and two-layer at least TPU material 10 carries out feeding by feeding roller respectively; TPU material 10 can be a rolling; Also can from extrusion die 5, extrude,, then get into step B if do not add glue between each TPU material 10; If add glue between each TPU material 10, then get into step C;
Step B carries out heating and pressurized treatments in heater 1 to each TPU material 10, makes each TPU expect that 10 hot pressing are one, and is as shown in Figure 1, gets into step D;
Step C carries out pressurized treatments to each TPU material 10, perhaps each TPU material is heated and pressurized treatments in heater 1, makes each TPU material paste for one through glue, and is as shown in Figure 2, gets into step D;
Step D, each the TPU material that becomes one is admitted to and carries out cooling processing in the cooling device 2;
Step e, after the cooling processing, the moulding of multilayer TPU attaching film is batched through winding up roller 9 at last and is finished product.
As preferred embodiment, the heating-up temperature of said heater 1 is 30 ° of C ~ 250 ° C, often adopts 50 ° of C, 100 ° of C and 150 ° of C etc.; The chilling temperature of said cooling device 2 is-20 ° of C ~ 35 ° C, often adopts 0 ° of C, 10 ° of C, 20 ° of C etc.; Said heater 1 is specifically decided according to the actual process needs for electrical heating, oil heating, gas heating or drum-type heater; Said cooling device 2 is air cooling or water-cooling apparatus, perhaps cools off guide wheel, freezes water machine etc.
Wherein, Fig. 3 and Fig. 4 are respectively that the utility model is the two-layer TPU thin layer different production sketch map when fitting, and same, its TPU material 10 can be a rolling, also can from extrusion die 5, extrude.
Wherein, the production sketch map when Fig. 5 is three layers of TPU thin layers applying for the utility model, same, its TPU material 10 can be a rolling, also can from extrusion die 5, extrude.Can repeatedly repeat processing and get final product more than four layers and four layers with reference to above-mentioned five kinds of methods.
The described a kind of multilayer TPU attaching film of the utility model; The TPU thin layers that multilayer is different fit together; Make it become the consistent integral body of performance through glue stickup or hot pressing mode; Product thickness can reach 0.02mm ~ 10mm, can improve the performances such as elasticity, toughness, wearability of TPU film, makes it be difficult for producing be full of cracks, break and other a series of rerum naturas such as not leakproof.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
