Description

High abrasion-proof PU leather structure

Technical field

The utility model relates to shoes to remove from office field technology, refer in particular to a kind of high abrasion-proof PU leather structure.

Background technique

Currently, common leather can divide into two major classes: natural leather and synthetic leather.

Natural leather is made of the skin for taking animal, such as sheepskin, ox-hide, and suture production article by leather makes for the mankind With such to be continued into the present by the way of leatherwork article, though existing natural leather has figure decoration, solid color is in beauty See the aesthetic quite dullness that seems.In addition the cost for obtaining natural leather is gradually increased, in the supreme viewpoint of modern trend trend On, substantially reduce modern purchase attraction.

Substitute of the synthetic leather as natural leather, is widely used in dress material, leather boots, suitcase etc..It is existing artificial synthesized Leather be generally combined by multilayer material, synthetic leather or artificial leather are by textile cloth base or non-woven fabrics base, respectively with poly- Urethane applies redoubling using made of special foaming processing, has surface feel to exactly like corium, but gas permeability, wearability are all not so good as very Skin.Especially in toughness and wearability, natural leather is much better than artificial synthetic leather.But due to the production restriction of corium, together When in order to economize on resources with old, can only use synthetic leather, how to improve artificial synthetic leather toughness and wearability become mentions The key factor of high leather quality.

Summary of the invention

In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of high abrasion PU leather structure can effectively solve the problem of existing rtificial leather toughness and wearability deficiency.

To achieve the above object, the utility model is using following technical solution:

A kind of high abrasion-proof PU leather structure includes base, anti-puncture layer, hot melt adhesive layer and PU surface layer；The base is Waterproof ventilative material；The anti-puncture layer is covered on the surface of base；The hot melt adhesive layer is covered on the anti-surface for piercing through layer；It should PU surface layer is covered on the surface of hot melt adhesive layer, which is high abrasion-proof PU skin.

Preferably, the bottom surface of the base is provided with pile layer.

Preferably, the hot melt adhesive layer with a thickness of 0.2-0.24mm.

Preferably, the PU surface layer with a thickness of 0.1-0.17mm.

The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology Known to scheme:

By the way that base is made by waterproof ventilative material, so that this product has preferable waterproof and breathable performance, and by setting It is equipped with anti-puncture layer, so that this product can prevent the piercing of sharp object, there is better protective effect, and, it is set by cooperation Hot melt adhesive layer PU surface layer is set, and PU surface layer is that high abrasion-proof PU skin can carry out so that this product has better toughness and wearability Thermoplasticity processing, product service life are also longer.

For the structure feature and effect for more clearly illustrating the utility model, come with reference to the accompanying drawing with specific embodiment pair The utility model is described in detail.

Detailed description of the invention

Fig. 1 is the sectional view of the preferred embodiment of the utility model.

Description of drawing identification:

10, base 20, anti-puncture layer

30, hot melt adhesive layer 40, PU surface layer

50, pile layer.

Specific embodiment

It please refers to shown in Fig. 1, it to include base that show the specific structures of the preferred embodiment of the utility model 10, anti-puncture layer 20, hot melt adhesive layer 30 and PU surface layer 40.

The base 10 is waterproof ventilative material, with a thickness of 0.3-0.4mm.

The anti-puncture layer 20 is covered on the surface of base 10, in the present embodiment, anti-puncture layer 20 be plastic cement material or Fiber Materials, with a thickness of 0.5-0.2mm, for preventing the piercing of sharp object.

The hot melt adhesive layer 30 is covered on the anti-surface for piercing through layer 20, in the present embodiment, the thickness of the hot melt adhesive layer 30 Degree is 0.2-0.24mm.

The PU surface layer 40 is covered on the surface of hot melt adhesive layer 30, also, the PU surface layer 40 is high abrasion-proof PU skin, in this reality Apply in example, the PU surface layer 40 with a thickness of 0.1-0.17mm.

And the bottom surface of the base 10 is provided with pile layer 50, so that dress is more comfortable.

When production, firstly, pile layer 50 is arranged on the bottom surface of base 10 when forming base 10, then, in base The anti-puncture layer 20 of 10 surface forming then forms hot melt adhesive layer 30 in the anti-surface coating hot-melt adhesive for piercing through layer 20, then will PU surface layer 40, which pastes, to be fixed on the surface of hot melt adhesive layer 30.

The design focal point of the utility model is: by the way that base is made by waterproof ventilative material, so that this product has preferably Waterproof and breathable performance so that this product can prevent the piercing of sharp object, have and preferably protect and by being provided with anti-puncture layer Shield effect, and, by being equipped with hot melt adhesive layer PU surface layer, and PU surface layer is high abrasion-proof PU skin, so that this product has more Good toughness and wearability, can be thermoformed, product service life is also longer.

Technical principle of the utility model has been described above with reference to specific embodiments.These descriptions are intended merely to explain this reality With novel principle, and it cannot be construed to the limitation to scope of protection of the utility model in any way.Based on the explanation herein, Those skilled in the art, which does not need to pay for creative labor, can associate with other specific implementation modes of this utility model, These modes are fallen within the protection scope of the utility model.
