Abstract
The utility model provides a kind of light high elasticity polyurethane midsole structure sheaf, including lower polyurethane foam material layer, middle polyurethane foam material layer and upper polyurethane foam material layer, it is characterised in that：The lower polyurethane foam material layer and middle polyurethane foam material layer are bonded as one by canvas layer, the middle polyurethane foam material layer top surface is laciniation, the upper polyurethane foam material layer bottom surface is laciniation, and the middle polyurethane foam material layer top surface and upper polyurethane foam material layer bottom surface top surface are mutually bonded into one structure.Polyurethane midsole provided by the utility model meets the high-elastic requirement of lightweight, also there is certain guarantee in terms of physical property, the characteristics of not only breathe freely comfortable with polyurethane, and meets the in the market consumer requirement attractive and durable for polyurethane midsole.
Description
Technical field
The utility model is related to a kind of polyurethane product, especially a kind of light high elasticity polyurethane midsole structure sheaf.
Background technology
China is the big economy in third place in the world, is also the second largest consumption market of polyurethane.The domestic product whole world
60% shoes.In addition, China human mortality is numerous, footwear are in great demand, and export volume increases year by year, the potential market of shoe-making industry
It is very big.Dress shoes light, comfortable, elegant in appearance have turned into a kind of new fashion of current people.Senior fortune is produced in recent years
The manufacturer of dynamic footwear produces midsole (being also midsole wedge) as an independent component, and latest fashion is competing with the market of fierceness
Strive, it is desirable to which the compact density of midsole is in 0.3 g/cm3Left and right, and to ensure dimensionally stable, surface skining is good, zero defect, this
Individual requirement is relative to a certain extent to be difficult to accomplish, particularly the client of outdoor exercises, high for the lightweight of polyurethane to tear
High-elastic physical property requirement is split, is extremely difficult in cast polyurethane field at present.
The midsole of some advanced motion brands in the market uses EVA material system for the requirement of lightweight, major part
Make lightweight midsole, rather than complete PU as midsole.In addition, in the production of current PU midsoles, big multi-density is in 0.4-0.5
g/cm3.Although EVA midsoles have a characteristic and advantage of its material itself, the finished product of EVA material be it is completely airproof, it is right
For consumer, a ventilative important index for being to directly affect level of comfort of sole, therefore it is midsole to use EVA
Shoes, the requirement for the material of vamp is just relatively high, and vamp must be poromeric material, so increased to a certain extent
Cost.For existing PU midsoles, density is a bit excessive, for consumers, too heavy, reduce comfort, with
On elaboration in, research and develop the urgent needs that a kind of light high elasticity polyurethane midsole is market.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is bottom structure in a kind of light high elasticity polyurethane of offer
Layer, by using special urethane material, can accomplish lightweight midsole of the density in 0.25-0.3D, and with elegant in appearance, easypro
Fit ventilative advantage.
The technical solution of the utility model is：A kind of light high elasticity polyurethane midsole structure sheaf, including lower polyurethane hair
Foam material layer, middle polyurethane foam material layer and upper polyurethane foam material layer, it is characterised in that：The lower polyurethane foam material
The bed of material and middle polyurethane foam material layer are bonded as one by canvas layer, and the middle polyurethane foam material layer top surface is sawtooth
Shape structure, the upper polyurethane foam material layer bottom surface is laciniation, the middle polyurethane foam material layer top surface and upper
Polyurethane foam material layer bottom surface top surface is mutually bonded into one structure.
The lower polyurethane foam material layer is horizontally arranged with several elastic cylinders in heel portion.
The elastic cylinder is that more than three and sectional area reduce successively from back to front.
The elastic cylinder is the column structure of circular oval or rectangle.
The elastic cylinder is made up of polyurethane foam or thermoplastic elastic material.
The surface of the upper polyurethane foam material layer is bonded with canvas layer.
If the lower polyurethane foam material layer, middle polyurethane foam material layer and upper polyurethane foam material layer be using
The composite construction layer that dry different colours, the monochromatic material layer of different densities are bonded as one.
The beneficial effects of the utility model are：Polyurethane midsole provided by the utility model meet lightweight it is high-elastic will
Ask, also there is certain guarantee in terms of physical property, the characteristics of not only breathe freely comfortable with polyurethane, and meet in the market consumer
The requirement attractive and durable for polyurethane midsole.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model light high elasticity polyurethane midsole structure sheaf.
In figure, polyurethane foam material layer under 1-, 2- canvas layers, polyurethane foam material layer in 3-, 4- laciniations,
The upper polyurethane foam material layers of 5-, 6- elastic cylinders.
Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of light high elasticity polyurethane midsole structure sheaf, including lower polyurethane foam material layer（1）, in
Polyurethane foam material layer（3）With upper polyurethane foam material layer（5）, it is characterised in that：The lower polyurethane foam material layer
（1）With middle polyurethane foam material layer（3）By canvas layer（2）It is bonded as one, the middle polyurethane foam material layer（3）Top
Face is laciniation（4）, the upper polyurethane foam material layer（5）Bottom surface is laciniation（4）, the middle polyurethane hair
Foam material layer（3）Top surface and upper polyurethane foam material layer（5）Bottom surface top surface is mutually bonded into one structure.
As further embodiment of the present utility model, the lower polyurethane foam material layer（1）In heel portion transverse direction
It is provided with several elastic cylinders（6）；The elastic cylinder（6）It is that more than three and sectional area reduce successively from back to front；Institute
State elastic cylinder（6）It is the column structure of circular oval or rectangle；The elastic cylinder（6）By polyurethane foam or thermoplastic
Property elastomeric material is made.
As further embodiment of the present utility model, the lower polyurethane foam material layer（1）, middle polyurethane foam
Material layer（3）With upper polyurethane foam material layer（5）It is to be bonded using the monochromatic material layer of several different colours, different densities
The composite construction layer being integrated；The upper polyurethane foam material layer（5）Surface be bonded with canvas layer（2）.
