Abstract
The utility model provides a novel TPU (Thermoplastic Polyurethane) thin film, relating to the technical field of decorative materials. The novel TPU thin film comprises a dry type TPU layer and a hot melt adhesive layer which are formed as a whole through coextrusion, adhesion or hot pressing. According to the novel TPU thin film, the property that the hot melt adhesive can be automatically adhered on a fabric after being cooled is utilized, so that adhesion with the fabric does not need glue; and the melting point of the hot melt adhesive is lower than that of the TPU, so that adhesion can be completed under the condition of relatively lower temperature.
Description
Technical field
The utility model relates to technical field of composite materials, particularly a kind of new TP U film for cloth pasting.
Background technology
TPU is the environmental protection macromolecule polymkeric substance, and Chinese name is thermoplastic polyurethane, and it has overcome many defectives of PVC and PU skin, the place of every use PVC, and TPU all can become the substitute of PVC.TPU not only has most of characteristic of rubber and common plastics, but also has good comprehensive physical and chemical property, so the following material that is otherwise known as.The TPU film is to adopt the TPU pellet, and by the film that special process is made, it has inherited the excellent in performance of TPU, and range of application is very extensive.
Owing to have avirulent advantage, meet environmental requirement, the TPU film product is widely used in the fields such as clothes, vamp and case and bag, the cloth that is fitted with the TPU film has good water-repellancy and ventilation property, but the TPU film can only be pasted by glue not sticking on voluntarily on the cloth after the cooling.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of glue that do not need just can be fitted in new TP U film on the cloth.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of new TP U film comprises dry type TPU layer and hot melt adhesive layer, and described dry type TPU layer and described hot melt adhesive layer are by co-extrusion or applying or hot-forming being integrated.
Preferably, a side of the relatively described dry type TPU layer of described hot melt adhesive layer is provided with embossed layers.
Pass through technique scheme, the new TP U film that the utility model provides, can stick on voluntarily the performance on the cloth after utilizing hot melt adhesive to cool off, dry type TPU layer and hot melt adhesive layer are shaped to one, thus, the TPU film need not to re-use glue with cloth pasting the time, and the fusing point of hot melt adhesive is lower than TPU fusing point, just can finish applying in the lower situation of relative temperature.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment.
Fig. 1 is the structural representation of the disclosed a kind of new TP U film of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
The utility model provides a kind of new TP U film (referring to Fig. 1), comprises dry type TPU layer 1 and hot melt adhesive layer 2, and dry type TPU layer 1 and hot melt adhesive layer 2 are by co-extrusion or applying or hot-forming being integrated.
One side of hot melt adhesive layer 2 relative dry type TPU layers 1 is provided with embossed layers 3.Embossed layers 3 can process exquisite pattern, after cloth and the utility model are fitted, and can be more attractive in appearance.
The new TP U film that the utility model provides, can stick on voluntarily the performance on the cloth after utilizing hot melt adhesive to cool off, dry type TPU layer and hot melt adhesive layer are shaped to one, thus, the TPU film is with cloth pasting the time, need not to re-use glue, and the fusing point of hot melt adhesive is lower than TPU fusing point, in the lower situation of relative temperature, just can finishes applying.
Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (2)
1. a new TP U film is characterized in that, comprises dry type TPU layer and hot melt adhesive layer, and described dry type TPU layer and described hot melt adhesive layer are by co-extrusion or applying or hot-forming being integrated.
