Description

A kind of three layers of tpu composite membrane

Technical field

This utility model is related to technical field of composite materials, specially a kind of three layers of tpu composite membrane.

Background technology

The entitled Polyurethane Thermoplastic Elastomer rubber of tpu (thermoplastic polyurethanes).It is broadly divided into Have polyester-type and polyether-type point, its hardness range width (60ha-85hd), wear-resisting, oil resistant, transparent, elasticity is good, article of everyday use, Be used widely in the fields such as sports goods, toy, ornament materials, halogen-free flameproof tpu can also replace soft pvc to meet more Carry out more multi-field environmental requirement.So-called elastomer refers to that vitrification point is less than room temperature, elongation at break > 50%, external force is removed Except the reasonable macromolecular material of rear restoration.Polyurethane elastomer is a relatively more special big class in elastomer, polyurethane bullet The hardness range of gonosome is very wide, and performance range is very wide, so polyurethane elastomer is the family macromolecule between rubber and plastics Material.Can heating plasticizing, chemical constitution does not have or seldom crosslinked, its molecule is substantially linear, but but exists certain Physical crosslinking, this kind of polyurethane is referred to as tpu.Now a lot of tpu materials has been made into composite membrane, but existing a lot Tpu composite membrane bearing capacity is not strong, compound membrane property can be led in a humid environment impaired so that composite membrane service life becomes Short, therefore devise a kind of three layers of tpu composite membrane.

Utility model content

For problem above, this utility model provides a kind of three layers of tpu composite membrane, by the design of three-layer type so that Tpu composite membrane has more preferable fastness, improves the load-carrying properties of composite membrane, high insulating effect, can be effectively applied to tide Wet environment, substantially prolongs the service life of composite membrane, is worthy to be popularized.

For achieving the above object, this utility model provides a kind of following technical scheme: three layers of tpu composite membrane, and it includes the One tpu film layer, the 2nd tpu film layer and the 3rd tpu film layer, are provided with first between a described tpu film layer and the 2nd tpu film layer Rubberised layer, is provided with the second rubberised layer between described 2nd tpu film layer and the 3rd tpu film layer, and a described tpu film layer upper end sets It is equipped with Concha Arcae film layer, described 3rd tpu film layer lower end is provided with lower Concha Arcae film layer, described first rubberised layer includes applying gum base Plate, described gluing substrate two ends are provided with water barrier.

As a kind of preferred technical scheme of this utility model, in a described tpu film layer, it is provided with through hole.

As a kind of preferred technical scheme of this utility model, in described 3rd tpu film layer, it is provided with lower through hole.

As a kind of preferred technical scheme of this utility model, in described 2nd tpu film layer, it is provided with cushion chamber.

Compared with prior art, the beneficial effects of the utility model are:

This utility model improves composite membrane by the design of three-layer type so that tpu composite membrane has more preferable fastness Load-carrying properties, high insulating effect, can be effectively applied to humidity environment, substantially prolongs the service life of composite membrane, value Must promote.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The every other embodiment being obtained, broadly falls into the scope of this utility model protection.

Embodiment:

Refer to Fig. 1 and Fig. 2, this utility model provides a kind of a kind of technical scheme: three layers of tpu composite membrane, it includes the One tpu film layer 1, the 2nd tpu film layer 2 and the 3rd tpu film layer 3, are provided between a tpu film layer 1 and the 2nd tpu film layer 2 One rubberised layer 4, is provided with the second rubberised layer 5 between the 2nd tpu film layer 2 and the 3rd tpu film layer 3, and a tpu film layer 1 upper end sets It is equipped with Concha Arcae film layer 6, the 3rd tpu film layer 3 lower end is provided with lower Concha Arcae film layer 7, the first rubberised layer 4 includes gluing substrate 8, apply Gum base plate 8 two ends are provided with water barrier 9, are provided with through hole 10 in a tpu film layer 1, are provided with the 3rd tpu film layer 3 Lower through hole 11, is provided with cushion chamber 12 in the 2nd tpu film layer 2.

Based on composite membrane adopts three layers of tpu film layer, between be provided with rubberised layer, glue can be coated well by tpu Film layer is glued together, and the water barrier using setting on rubberised layer prevents water penetration well, is made entirely multiple using Concha Arcae film layer Close film and there are more preferable load-carrying properties, by the through hole of setting in upper and lower two tpu film layers, composite membrane is had preferably Penetration performance, by the design of cushion chamber so that composite membrane has preferably pressure performance, by the design of three-layer type so that Tpu composite membrane has more preferable fastness, improves the load-carrying properties of composite membrane, high insulating effect, can be effectively applied to tide Wet environment, substantially prolongs the service life of composite membrane, is worthy to be popularized.
