Description
Technical field
This utility model relates to a kind of thin film, particularly to a kind of TPU hot melt adhesive film.
Background technology
TPU hot melt adhesive film is a kind of thermoplastic polyurethane.Also it is a kind of environmental protection macromolecule polymer simultaneously.It has nothing
The feature such as malicious, wear-resisting.But its tensile strength is relatively low, in use, it is easy to by External Force Acting occur stretching or fracture
Situation.
In order to overcome this type of defect, the basic unit of TPU hot melt adhesive film would generally be thickeied by this skilled person, although has
Certain tension effect, but improve production cost.
Summary of the invention
The deficiency existed for prior art, this utility model provides a kind of elastic and tension is effective, simple in construction,
The TPU hot melt adhesive film of low production cost.
For achieving the above object, this utility model provides following technical scheme: a kind of TPU hot melt adhesive film, includes poly-
Urethane body layer and the basal layer bonded by PUR, it is characterised in that: described basal layer is towards polyurethane body layer one
The end face of end is provided with elastic tension assembly, and this elasticity tension assembly includes along the transversely arranged elastoplast silk of basal layer,
By connecting plastic wire connection between each elastoplast silk, the diameter that is axially respectively arranged at two ends with of elastoplast silk is moulded more than elasticity
The contiguous block of material silk, wherein the contiguous block of one end is connected with polyurethane body layer, and the contiguous block of the other end is connected with basal layer.
Use technique scheme, by arranging elastic tension assembly on the base layer, make polyurethane body layer have more
Good elasticity and preferably pull resistance.Elasticity tension assembly is set to elastoplast silk the most easy to process, with low cost,
Do not interfere with the folding of TPU hot melt adhesive film simultaneously, implement to connect by connection plastic wire between elastoplast silk and then can yet
Further improve the toughness of elastoplast silk, can prevent elastoplast silk from the situation of fracture in use occurring.
This utility model is further arranged to: being axially respectively arranged at two ends with for elastic plastic wire grafting of each connection plastic wire
Connection ring.
Use technique scheme, processing is so set and installs more convenient.
This utility model is further set to: basal layer is relative to the other end with polyurethane body laminating unification end
It is evenly equipped with some plastics reinforcements on end face, is connected by support bar respectively between each reinforcement.
Use technique scheme, so arrange and the tensile strength of basal layer can be made to be further improved, prevent base
There is stretching and the situation of fracture in bottom.
Below in conjunction with the accompanying drawings this utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
A kind of TPU hot melt adhesive film as shown in Figure 1, includes polyurethane body layer 1 and the substrate bonded by PUR
Layer 2, basal layer 2 is provided with elastic tension assembly 3 towards the end face of polyurethane body layer 1 one end, and this elasticity tension assembly 3 includes
Have along the transversely arranged elastoplast silk 31 of basal layer 2, connect by connecting plastic wire 32 between each elastoplast silk 31, elastic
Plastic wire 31 be axially respectively arranged at two ends with diameter more than the contiguous block 311 of elastoplast silk, wherein the contiguous block 311 of one end with
Polyurethane body layer 1 connects, and the contiguous block of the other end is connected with basal layer 2.In such scheme, by arranging on basal layer 2
Elastic tension assembly 3, makes polyurethane body layer 1 have the most elastic and more preferable pull resistance.Elasticity tension assembly 3 is arranged
Easy to process for elastoplast silk 31 1 aspect, with low cost, do not interfere with the folding of TPU hot melt adhesive film simultaneously yet, elastic
Then can further improve the toughness of elastoplast silk 31 by connecting plastic wire 32 enforcement connection between plastic wire 31, can
Prevent elastoplast silk 31 from the situation of fracture in use occurring.
In this utility model embodiment, for the ease of each elastoplast silk 31 and the connection being connected between plastic wire 32,
Respectively connect plastic wire 32 is axially respectively arranged at two ends with the connection ring 321 for elastic plastic wire 31 grafting.Certainly, explanation is needed
It is, it is possible to directly elastoplast silk 31 is welded with being connected plastic wire 32, be also feasible, or is implemented even by knotting
Connect.
In order to further improve the pull resistance of basal layer 2, basal layer 2 unifies end relative to polyurethane body 1 laminating
The other end end face on be evenly equipped with some plastics reinforcements 21, be connected by support bar 22 respectively between each reinforcement 21.
Claims (3)
1. a TPU hot melt adhesive film, includes polyurethane body layer and the basal layer bonded by PUR, it is characterised in that:
