Abstract

The utility model discloses a ventilative impervious type etpu puffed rice shoe-pad, including etpu buffer layer and adopt the mould pressing mode to fuse the tpu ventilated membrane in etpu buffer layer top, be formed with a plurality of perforating hole on the etpu buffer layer. Compared with the prior art, the utility model has the characteristics of air permeability is good, moreover owing to can not permeate water from top to bottom, can keep a small amount of sweat in the shoe-pad top and can not permeate to shoe-pad upper surface below to improve people greatly and keep clean convenient degree.

Description

Breathable waterproof etpu popcorn insole

Technical Field

The utility model relates to an elasticity shoe-pad field, concretely relates to ventilative impervious type etpu puffed rice shoe-pad.

Background

The conventional etpu popcorn elastic insole in the market is generally formed by carrying out vapor forming on etpu particles in a mould to obtain a damping sheet, and then, a mesh fabric layer brushed with a layer of bonding glue is adopted to connect the mesh fabric layer and the damping sheet together in a composite mode to obtain a finished product elastic insole.

Above-mentioned elasticity shoe-pad is though the preferred in damping performance, but because the shock attenuation sheet of shoe-pad all adopts integral type structure shaping, its air permeability is relatively poor, produces the situation of sealing the foot easily, though prior art someone is through the mode that the brush glue punched, nevertheless because the setting of glue, still to a great extent has influenced the gas permeability of whole elasticity shoe-pad.

In view of the above, the applicant has made an intensive study on the above problems, and has made the present invention.

SUMMERY OF THE UTILITY MODEL

The main object of the utility model is to provide a ventilative impervious type etpu puffed rice shoe-pad to solve the problem that etpu puffed rice shoe-pad is relatively poor at air permeability among the prior art.

In order to achieve the above purpose, the solution of the present invention is:

a breathable and waterproof etpu popcorn insole comprises an etpu damping layer and a tpu breathable film fused above the etpu damping layer in a mould pressing mode, wherein a plurality of through holes are formed in the etpu damping layer.

Furthermore, the through holes are formed by synchronous molding of a die in the foaming molding process of the etpu damping layer.

Further, the thickness of the etpu damping layer is 4mm-9 mm.

Further, the Shore hardness of the etpu damping layer is 20-40.

After the structure of the oil adding device is adopted, the utility model relates to a ventilative impervious type etpu puffed rice shoe-pad, it is through adopting the tpu ventilated membrane (also having on the market and being called the waterproof ventilated membrane of tpu), and adopt the mode of mould pressing, utilize the characteristics of two kinds of material isogenesis of tpu ventilated membrane material and etpu buffer layer, the mutual integration nature that exists between each other promptly lets both zonulae occludens together, make from this and need not reuse glue between each other, avoided stopping up the perforating hole because glue and brought the problem that influences the gas permeability.

And simultaneously, the utility model discloses an adopt the tpu ventilated membrane, it can let a small amount of sweat that human foot flows can not directly permeate below the shoe-pad upper surface, and people can conveniently realize that personal hygiene is clean through changing clean shoe-pad every day very much, need not often to wash shoes.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1 and 2, the utility model relates to a ventilative impervious etpu puffed rice shoe-pad, including etpu shock-absorbing layer 10 and adopt the mould pressing mode to fuse the tpu ventilated membrane 20 in etpu shock-absorbing layer 10 top, be formed with a plurality of perforating hole 11 on the etpu shock-absorbing layer 10.

Specifically, in this embodiment, the through holes 11 are formed by synchronously molding the etpu damping layer 10 in a foaming process through a mold, so that the process efficiency is greatly improved, and in addition, in order to allow the through holes 11 to have a better comfort performance, the through holes 11 are divided into two parts which are arranged at intervals and correspond to a forefoot area and two parts which are arranged at intervals and correspond to a heel area.

Therefore, the utility model relates to a ventilative impervious type etpu puffed rice shoe-pad, it is through adopting the tpu ventilated membrane 20 (also have on the market to be called the waterproof ventilated membrane of tpu), and adopt the mode of mould pressing, utilize the characteristics of two kinds of material isogenesis of tpu ventilated membrane 20 material and etpu buffer layer 10, the mutual integration nature that exists between each other promptly lets both zonulae occludens together, make from this and need not reuse glue between each other, avoided stopping up perforating hole 11 and bring the problem that influences the gas permeability because glue.

And simultaneously, the utility model discloses an adopt the tpu ventilated membrane 20, it can let a small amount of sweat that human foot flows can not directly permeate below the shoe-pad upper surface, and people can conveniently realize that personal hygiene is clean through changing clean shoe-pad every day very much, need not often to wash shoes.

In order to further improve the wearing comfort of the whole insole, the invention is selected, preferably, the thickness of the etpu damping layer 10 is 4mm-9mm, and the shore hardness of the etpu damping layer 10 is 20-40. Therefore, under the conditions of the thickness and the Shore hardness, the wearing comfort of the insole can be ensured to be optimal.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
