Problems solved by technology

This method is only a method for making the midsole or the outsole of the shoe or the sole containing only the outsole or the midsole, and the appearance and color of the finished product are relatively single, and the sense of design is relatively poor.
[0008] Other existing one-piece shoe sole manufacturing methods may have paid attention to the consumer demand for layers and colors, but due to the overflow of foaming materials during the injection molding process, excess scraps need to be trimmed and removed in the post-processing process. In this process, even if It is operated by skilled workers, and many defective products are born, and the wide cut surface left after trimming affects the appearance of the sole

Embodiment 1

[0042] A kind of waterproof sole that embodiment 1 prior art provides

[0043] see figure 1 , what this figure shows is a kind of waterproof sole in the prior art. This waterproof sole is made of two parts, is respectively the PU midsole 1 and the rubber outsole 2 that are fully covered by the TPU film from top to bottom. When being made into shoes, it is necessary to cold-bond the upper and the PU midsole fully covered by the TPU film of the waterproof sole with an adhesive.

[0044] Though the shoe sole that this method makes has certain waterproof effect, sole can only show double-deck, double grain and double color effect. In addition, the method of cold bonding and fixing with adhesive is also prone to glue opening during wearing.

Embodiment 2

[0045] Another kind of waterproof sole preliminary product that embodiment 2 prior art provides

[0046] see figure 2 , what this figure shows is the schematic diagram of another kind of waterproof sole preliminary product in the prior art. This waterproof sole is made of two parts, is foamed PU midsole 11 and TPU outsole 12 respectively from top to bottom. Due to the adoption of the integral molding injection molding process to manufacture shoes, the periphery of the foamed PU midsole has more burrs formed by the foamed PU that overflows to the side. Later, when trimming the burr, skilled workers need to master the coordination between the trimming machine and the arc of the hand movement. The operation requires high technical proficiency, and the finished product after trimming has a wide cutting surface, and the aesthetics of the shoes is not high. In addition, this shoe is identical with embodiment 1, can only present the sole of double-layer, double-grain and double-co...

Embodiment 3

[0047] Embodiment 3 A kind of waterproof and dirt-resistant sole, shoes and production method thereof

[0048] see image 3 , what this figure shows is the schematic diagram of a kind of waterproof and dirt-resistant shoe sole described in the specific embodiment of the present invention. The waterproof and dirt-resistant sole is composed of three layers, the upper part is a foamed PU layer 101, the middle part is coated with a foamed PU layer 102 by a TPU waterproof membrane, and the bottom TPU waterproof membrane is coated with a large bottom layer 103. Specifically, the waterproof and dirt-resistant sole includes a large bottom, a waterproof film layer (made of TPU), and a midsole (made of foamed PU). The lower half of the bottom forms a TPU waterproof membrane and covers the foamed PU layer 102. The lower half is the area of ​​the midsole close to the outsole, and the waterproof membrane layer is TPU. The waterproof film layer is close to the outsole, and fills the hollo...

Abstract

The invention belongs to the technical field of shoemaking, and particularly relates to a waterproof dirt-resistant sole, a waterproof dirt-resistant shoe and a production method of the waterproof dirt-resistant sole. According to the sole composed of the outsole, the TPU waterproof film layer and the insole, the TPU waterproof film layer can be made into films with various colors according to needs, so that the sole shows different colors and layering effects. The sole provided by the technical scheme of the invention can realize three materials, three lines and three colors, and has excellent hydrolysis resistance, tear resistance and bending resistance. The TPU waterproof film is thin and fit, and can form an excellent fitting effect with EVA, rubber or PU. According to the unique manufacturing process provided by the invention, burrs of a shoe primary product are TPU waterproof film layers, trimming is simple and rapid, and compared with a traditional method, the trimming surface of the trimming position of a shoe finished product is greatly reduced, and the attractiveness is enhanced. In addition, the amount of the trimmed waste TPU waterproof film layer is controllable, the material waste for producing the shoe is reduced, the material utilization rate is improved, and the production cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of shoemaking, and more particularly relates to a waterproof and dirt-resistant sole, a shoe and a production method thereof. Background technique [0002] With the improvement of people's living standards, the demand for shoes consumption is becoming more and more diversified. It is not limited to the comfort of wearing and walking. Consumers' demand for personalized appearance, aesthetics, waterproof and dirt-resistant functions of shoes is constantly increasing. How to improve the production efficiency of shoes and the utilization rate of shoe-making materials, and how to reduce the environmental pollution caused by the shoe-making industry have also become new issues faced by this traditional industry. [0003] The structure of shoes can be generally divided into two parts: the sole and the upper. As far as the soles are concerned, most of them are still produced by producing the big bottom and the midd...
