Abstract

The utility model discloses a polyurethane insole, which comprises a polyurethane foam body. The foam of the polyurethane foam body is hole-opened non-cut polyurethane foam without plasticizer, and waterproof breathable polyurethane integral skins are formed on the upper surface and the lower surface of the polyurethane foam body. The polyurethane insole has the advantages of sweating constraint, moisture exhaust, slipping prevention, shock proofing, and resistance to deformation.

Description

Polyurethane insole

Technical field

The utility model relates to a kind of shoe-pad, particularly a kind of polyurethane insole.

Background technology

At present; Polyurethane obtains application more and more widely in footwear are made, also occurred the shoe-pad that panoramic polyurethane material is made on the market, is 200720047448.4 " hydrophilic polyurethane shoe-pad " like the patent No.; A kind of hydrophilic polyurethane shoe-pad with three-decker is provided; Its principal character is: its top layer is the anti-skidding cloth of breathing freely, and the middle level is that the hydrophilic polyurethane bubble is continuous, the continuous sweat that can absorb foot's generation easily of this hydrophilic polyurethane bubble; Foot is remained under the dry nice and cool environment, and bottom is polyurethane flexible foam or EVA expanded material.The polyurethane insole of this structure need carry out compound to multiple moulding material; Inconvenient machining, and the shoe-pad that is composited of multiple moulding material are in long-term walking process; Receive the pressure effect of pin, cause easily such as bad phenomenon such as shoe-pad distortion, layers of material displacements.

The utility model content

The purpose of the utility model is in order to overcome the shortcoming and defect that prior art exists, and a kind of have arrest sweating hydrofuge, anti-skidding shockproof, on-deformable new polyurethane shoe-pad are provided.

The technical scheme that the utility model adopted is: adopt the polyurethane foam sponge body as insole body; The used bubble of said polyurethane foam sponge body is continuous continuous for the non-cutting polyurethane foam of the open cell type that adopts no plasticizer polyurethane stock solution foaming, and the polyurethane that polyurethane foam sponge body upper and lower surfaces is formed with waterproof and breathable is from skinning.

The further setting of the utility model is: said polyurethane insole surface also is provided with skid resistant course.

The further setting of the utility model is: said polyurethane insole is sole type shoe-pad or heel type shoe-pad.

The utility model has the advantages that: the bubble that insole body polyurethane foam sponge body is adopted is continuous to be that the non-cutting polyurethane foam of no plasticizer open cell type is continuous; Promptly adopt the polyurethane stock solution that does not add plasticizer to be foamed into the open pore polyurethane bubble silk floss of the required thickness of shoe-pad; Open cell type bubble silk floss is that the bubble of possess hydrophilic property is continuous; Owing to do not add plasticizer, so the polyurethane foam silk floss possesses very strong compression set resistant ability, and the passing that such shoe-pad can be not in time and shrink, become fragile or rupture.The cutting of the utility model indication; Refer in particular to transverse cuts commonly used in the continuous processing of bubble; Non-cutting promptly need not transverse cuts, because the continuous thickness of the polyurethane foam of foaming is the shoe-pad desired thickness, so need not the polyurethane foam silk floss is carried out transverse cuts processing; Because the above-mentioned characteristic that this polyurethane foam is continuous, so it is continuous to be referred to as not have the non-cutting polyurethane foam of plasticizer open cell type.The polyurethane that polyurethane foam sponge body upper and lower surfaces is formed with waterproof and breathable is from skinning, and polyurethane can form in the continuous foamed forming process of polyurethane foam from skinning naturally, because take the processing mode of non-cutting; Therefore polyurethane is able to keep from the upper and lower surfaces of skinning at the polyurethane foam sponge body, and polyurethane possesses elastic water-proof, permeability from the particularity of skinning because of its molecular structure; The effect meeting that is stressed of liquid porous not under normal pressure, but under the pressure effect in vola, liquid is slowly permeated polyurethane from skinning; So just guaranteed polyurethane insole in waterproof, the permeable shoe-pad of sweat top layer is afterwards again by the continuous absorption of the polyurethane foam of internal layer; Because this polyurethane foam is continuous continuous for the open pore polyurethane bubble, open pore polyurethane bubble silk floss possesses the high-efficiency water-absorbing performance, can absorb the sweat that foot produces easily; Form gel, no matter how to push again, can wetly moist socks yet; It is so-called arrest sweating hydrofuge; So just can an environment that drying is salubrious be provided to foot, dry environment is difficult for breed bacteria, so the utility model also possesses certain deodorization effect.Can learn by foregoing description; The utility model machine-shaping is convenient; The polyurethane insole that has the waterproof and breathable function of relative composite, the utility model possesses incorporate inherent advantage, has guaranteed the firmness of shoe-pad; Simultaneously because the polyurethane foam silk floss itself possesses remarkable shock absorbing capability, so the utility model also possesses shockproof properties.For preventing that extruding causes shoe-pad in footwear, to slide to foot to shoe-pad; The polyurethane insole surface that the utility model provides is provided with skid resistant course; In order to make shoe-pad pacify pin more, the sole type that is shaped as or the heel type of the polyurethane insole that the utility model provides can effectively slow down walking fatigue.Should be noted that the shape of the skid resistant course and the shoe-pad of the utility model, can be through extruding one-shot forming to the polyurethane foam silk floss.

Below in conjunction with the Figure of description and the specific embodiment the utility model is done further introduction.

The specific embodiment

Like Fig. 1, Fig. 2, polyurethane insole shown in Figure 3; Comprise polyurethane foam sponge body 1, polyurethane foam body 1 is continuous for the non-cutting polyurethane foam of no plasticizer open cell type, promptly adopts the polyurethane stock solution that does not add plasticizer to be foamed into the open pore polyurethane bubble silk floss of the required thickness of shoe-pad; Open pore polyurethane bubble silk floss is that the polyurethane foam of possess hydrophilic property is continuous; Since do not add plasticizer, so the final polyurethane foam sponge body 1 that forms possesses very strong compression set resistant ability, the cutting of the utility model indication; Refer in particular to transverse cuts commonly used in the continuous processing of bubble; Non-cutting promptly need not transverse cuts, because the continuous thickness of the polyurethane foam of foaming is the shoe-pad desired thickness, so need not the polyurethane foam silk floss is carried out transverse cuts processing.Polyurethane foam sponge body 1 upper and lower surfaces is formed with the polyurethane of waterproof and breathable from skinning 11; Polyurethane can form in the continuous foamed forming process of polyurethane foam from skinning 11 naturally; Because take the processing mode of non-cutting; Therefore polyurethane is able to keep from the upper and lower surfaces of skinning 11 at polyurethane foam sponge body 1, plays the effect of waterproof and breathable.For preventing that extruding causes shoe-pad in footwear, to slide to foot to shoe-pad, the polyurethane insole surface that present embodiment provides also has additional skid resistant course 12, more pacifies pin for making polyurethane insole, and the shoe-pad that the utility model provides is a heel type shoe-pad.

The skid resistant course 12 in the present embodiment and the insole shape of heel type are through the extruding one-shot forming to the polyurethane foam silk floss.
