Description

A kind of tpu thin film

Technical field

This utility model is related to technical field of composite materials, specially a kind of tpu thin film.

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.But tpu thin film a lot of at present is when in use, due to the change of temperature, Internal structure can be led to draw in because of temperature change, thin film can be led to for a long time to lead to due to tighter fixing force surface to be broken Split, film damper performance is relatively low, therefore devise a kind of tpu thin film.

Utility model content

For problem above, this utility model provides a kind of tpu thin film, the structural stability of thin film can be kept so that Thin film good self regulation in the case of temperature change, thin film internal structure can freely stretch gathering, it is to avoid tpu thin film Because tighter fixing force leads to face checking, extend the service life of tpu thin film, be worthy to be popularized.

For achieving the above object, this utility model provides a kind of following technical scheme: tpu thin film, and it includes tpu basic unit, Described tpu basic unit lower end is provided with cushion, and described cushion is provided with air-vent, the side of described tpu basic unit and cushion Edge contact point is provided with plastic packaging layer, and described cushion lower end is provided with mucigel, and described mucigel lower end is provided with pe film layer, described Pe film layer lower end is provided with tpu film layer, and described tpu film layer lower end is provided with release layer, sets between described tpu film layer and release layer It is equipped with sol layer, described cushion includes buffer substrate, in described buffer substrate, be provided with oval buffer cavity.

As a kind of preferred technical scheme of this utility model, described tpu basic unit upper end is provided with non-slip bumps, described anti- Sliding projection cross section is semicircular structure.

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

As a kind of preferred technical scheme of this utility model, in described release layer, it is provided with fiber reinforced material.

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

This utility model can keep thin film structural stability so that thin film in the case of temperature change well self Adjust, thin film internal structure can freely stretch gathering, it is to avoid tpu thin film leads to face checking due to tighter fixing force, prolongs Grow the service life of tpu thin film, be worthy to be popularized.

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: tpu thin film, and it includes tpu basic unit 1, Tpu basic unit 1 lower end is provided with cushion 2, and cushion 2 is provided with air-vent 3, the EDGE CONTACT of tpu basic unit 1 and cushion 2 Point is provided with plastic packaging layer 4, and cushion 2 lower end is provided with mucigel 5, and mucigel 5 lower end is provided with pe film layer 6, and pe film layer 6 lower end sets It is equipped with tpu film layer 7, tpu film layer 7 lower end is provided with release layer 8, is provided with sol layer 9 between tpu film layer 7 and release layer 8, delay Rush layer 2 and include buffer substrate 10, in buffer substrate 10, be provided with oval buffer cavity 11, tpu basic unit 1 upper end is provided with anti-skidding Projection 12, non-slip bumps 12 cross section is semicircular structure, is provided with permeability hole 13, is provided with fibre in release layer 8 in pe film layer 6 Dimension reinforcement 14.

Setting cushion ensure both can fixing-stable, tpu basic unit produces deformation in temperature change, cushion meeting Stretch with tpu basic unit or draw in, it is to avoid tpu thin film leads to face checking due to tighter fixing force, setting air-vent adds The stretching, extension of strong cushion and gathering effect, also ensure that in film, ventilative degree is to reduce the temperature difference, and around cushion in tpu basic unit Plastic packaging layer avoids dust or debris to enter cushion and hinders stretching, extension and draw in, the structural stability of thin film can be kept so that Thin film good self regulation in the case of temperature change, thin film internal structure can freely stretch gathering, it is to avoid tpu thin film Because tighter fixing force leads to face checking, extend the service life of tpu thin film, be worthy to be popularized.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in this utility model Protection domain within.
