Embodiment 1

[0039] Such as figure 1 , figure 2 Shown:

[0040] A waterproof and breathable shoe, comprising a waterproof and breathable upper, the upper surface of the shoe upper is distributed with micropores 1 passing through its upper and lower surfaces, and the micropores 1 are breathable and impervious to water. The material of the upper is elastic waterproof material. The elastic waterproof material includes EVA, of course, the elastic waterproof material can also be composed of other components. The diameter of the micropores 1 is small enough to prevent water from seeping through the micropores 1 into the shoe due to tension.

[0041] Preferably, the thickness range of the shoe upper with the microholes 1 is 3mm-6mm, such as 4mm, 5mm.

[0042] Preferably, 200-300 micropores 1 are evenly distributed on the whole shoe upper, such as 220, 240, 260, 280.

[0043] The manufacturing method of the waterproof breathable shoes of the present embodiment comprises the following steps: ...

Embodiment 2

[0050] Such as figure 1 , figure 2 Shown:

[0051] On the basis of Example 1, another elastic waterproof material is selected for the shoe upper of this example, and the other elastic waterproof material comprises the following components in parts by weight: 70 parts of EVA, and 30 parts of elastomer.

[0052] Since the elastic waterproof material includes two components, it is necessary to knead the components.

[0053] The manufacturing method of the waterproof breathable shoes of the present embodiment comprises the following steps:

[0054]1. Mix the components together to obtain the elastic waterproof material, mold the elastic waterproof material into a semi-finished product of the upper of the waterproof and breathable shoe, the semi-finished product has the shape and size of the upper of the shoe, the Molding is preferably injection molding using an injection molding machine;

[0055] 2. Perform cooling treatment on the semi-finished shoe upper, preferably, reduce...

Embodiment 3

[0059] Such as image 3 , Figure 4 Shown:

[0060] A waterproof and breathable shoe, comprising a waterproof and breathable upper, the upper is distributed with micropores 1 passing through its upper and lower surfaces, the micropores 1 are breathable and impervious to water, the upper is made of elastic waterproof material, and the elastic waterproof The material includes the following components by weight: 28.5-38 parts of Eva, 4.75-9.5 parts of light calcium, 2.375-4.75 parts of talcum powder, 0.95-3.8 parts of water-absorbing agent, 2.375-4.75 parts of pottery clay, and 0.3325-0.57 parts of dcp bridging agent 1.425-2.85 parts of ac foaming agent, 1.425-2.85 parts of stearic acid, 1.425-2.375 parts of zinc oxide, 9.5 parts of poe elastomer, 33.25 parts of Eva vinyl acetate. The apertures of the micropores 1 gradually shrink from one side of the upper surface to the other side. The micropores 1 whose pore diameters shrink gradually widen the ventilation channel between t...

Abstract

The invention relates to a waterproof and air-permeable shoe, which comprises a waterproof and air-permeable upper. The upper is made of an elastic waterproof material. Micropores which run through the upper surface and the lower surface of the upper are distributed on the surface of the upper. The micropores are air-permeable and watertight. At the same time, the invention additionally disclosesthe production method of the waterproof and air-permeable shoe. The method comprises the following steps of: 1) molding the semi-finished upper of the waterproof and air-permeable shoe by using the elastic waterproof material, wherein the semi-finished upper has the shape and the size of the upper; 2) cooling the semi-finished upper; 3) using a fine needle to pierce the surface of the cooled semi-finished upper to form the micropores of the upper, so as to form the upper of the waterproof and air-permeable shoe; and 4) hermetically connecting the upper and a sole to form the waterproof and air-permeable shoe. The production method of the waterproof and air-permeable shoe is simple, the cost is low and the waterproof and air-permeable performance is good.

Description

technical field [0001] The invention relates to the field of footwear, in particular to a waterproof and breathable shoe and a manufacturing method thereof. technical background [0002] At present, the commonly used waterproof and breathable method for the upper is to attach a waterproof and breathable upper inner layer material inside the upper outer layer material with air holes, and adopt this double-layer structure to realize the waterproof and breathable effect of the upper. However, the waterproof and breathable inner layer material of the shoe upper increases the cost of the shoe, and causes the structure of the upper of the shoe to be complicated and the manufacturing process to be complicated. Contents of the invention [0003] In order to solve the technical problem of the high cost of the waterproof and breathable shoes with a double-layer upper, the present invention proposes a waterproof and breathable shoe with a single-layer upper without the inner material...
