Description
Technical field
The utility model is related to a kind of shoe pad product, and especially one kind prepares new polyurethane two-layer compound with post forming
The polyurethane insole of high cohesive force based on material.
Background technology
The proximal segment time, with the lasting extension in footwear material dull season, price war is beaten louder and louder in the footwear material industry of native country.And price
Firing for war, has also further been catalyzed the fieriness of whole footwear material industry competition.Under such background, to tackle price war, much
Footwear material enterprise starts, from internal " decompression ", internally to carry out self specification.At the same time, it is then externally to be made the transition to middle and high end category,
In the hope of obtaining more development spaces.Polyurethane elastomer is commonly used in footwear material field, because it has shock-absorbing capacity
Good, light weight, it is wear-resisting, anti-skidding the advantages of, as a kind of important supplementary material in shoemaking industry, golf shoes, baseball
The important accessories such as sole, heel, toe-cap, the shoe-pad of many footwear such as footwear, football boot, ski boots, sneakers, safety shoe are all with poly-
Chlorine ester elastomer is made, not only elegant in appearance, and comfortable durable, moreover it is possible to improve sports achievement.Many is developed in recent years
Easy processing new varieties, as appropriate for dual-color forming, can increase the transparency and high flowing, it is high reclaim improve processing efficiency type
Polyurethane elastomer, shoe-making field is expanded and China has turned into global shoemaking base at present, not only to polyurethane elastomer
Demand be significantly increased, and the improvement of its technology is extremely expected.Pursued the strategy of sustainable development energetically in country, Yi Jiquan
Under the overall situation of ball financial crisis, to new environmental protection, low toxicity, harmless, inexpensive, high-performance polyurethane elastomer material need
Seek more and more higher.
In the prior art, double-deck polyurethane footwear material secondary shaping tech is concentrated mainly on elastic polyurethane expanded material, i.e.,
Up and down two layers it is uniform there is the polyurethane foam material of resilience effect, and be directed to upper strata for slow rebound polyurethane foam, lower floor
For the composite construction of rebound polyurethane foam, current production technology, which only stays in, first enters the material of two kinds of different resilience effects
Cut-parts are carried out after row foam box, then are bonded with glue, upper strata is prepared for low resilience effect finally by the mode of cut-parts,
Lower floor is the polyurethane insole of the double-deck high cohesive force of resilience effect.But the problem of existing is：1st, the preparation process of complicated multistep,
It is related to a variety of preparation technologies, cost is added while virtually reducing efficiency；2nd, the substrate surface effect of cut-parts is not ideal,
And directly contact skin is easy to fall off when rubbing repeatedly, one layer of layer of cloth need to be increased in upper surface and make up deficiency in the mechanics of materials；Cause
Need to be bonded using glue in Material cladding, the requirement to working environment is higher.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to develop a mould of design, the mould structure energy
By slow rebound polyurethane material and rebound polyurethane material, self-adhesive forms band from the improvement surface effect of skinning in molding
Dual density shoe-pad, the shoe-pad has comfortable low resilience upper strata and provides the resilience lower floor of enough support forces.
The technical solution of the utility model is：A kind of polyurethane insole of high cohesive force, including upper insole material layer is with
Insole material layer, it is characterised in that：The upper insole material layer bottom surface is zigzag planar structure, the lower insole material layer top
Face is zigzag planar structure, and the upper insole material layer bottom surface and lower insole material layer top surface are mutually bonded into one structure,
The upper sole material bed of material and the lower sole material bed of material are the different material layer of density.
The upper insole material layer and lower insole material the layer polyurethane foam material layer that to be rebound degree different, and upper shoe-pad
The rebound degree of material layer is less than lower insole material layer.
The surface of the upper insole material layer is bonded with canvas layer.
The upper insole material layer and the monochromatic material layer that lower insole material layer is different colours, the lower insole material layer
Heel part be horizontally arranged with several elastic cylinders.
Provided with a groove, it has been laterally embedded into the upper insole material layer at front foot transverse palmar arch in the groove
Elastic cylinder；The elastic cushioning material is made up of the thermoplastic elastic material of high bounce-back, Highly-absorbing.
The elastic cylinder is circular, ellipse or the column structure of rectangle.
The beneficial effects of the utility model are：The polyurethane insole of the high cohesive force of dual density of the present utility model is made for molding
Product, can form a kind of fine and close epidermis in preparation process, and epidermal thickness can be adjusted according to formula, greatly be modified double
The surface effect and mechanical property of density shoe-pad, if necessary, the mould may be designed as with dossal function, can be according to client's need
Ask, increase a kind of canvas layer newly in its upper surface, and the canvas is bonded into without glue, and can in molding process because
Own material reacts phase transformation and realizes self-adhesive effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, insole material layer under 1-, the upper insole material layers of 2-, 3- elastic cylinders.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of polyurethane insole of high cohesive force, including upper insole material layer（2）With lower insole material layer
