Embodiment 1

[0042] A method for processing thermoplastic elastic insoles. TPR thermoplastic elastomer (thermoplastic rubber) is selected as the main raw material. TPR thermoplastic elastomer is based on styrene-ethylene / butylene-styrene (SEBB) polymer as the main raw material, and naphthenic Oil and other polymers (such as PP) are mixed in a certain proportion. The processing method uses the following processing steps, such as figure 1 , 2 Shown:

[0043] a. Ingredients: TPR thermoplastic elastomer and toner, according to the weight ratio of 10000:8 or 10000:12 or 10000:16, it is best to use the weight ratio of 10000:12; send it to the kneader to knead 20 or 30 or 40 minutes, the best kneading time is 30 minutes;

[0044] b. Punching: The fabric base material is punched into the required insole mold shape to form the cushion cloth 1 (to fit the shape of the insole). The fabric base material in this embodiment is a composite cloth, which is composed of a layer of velvet and a white pair The s...

Embodiment 2

[0056] A method for processing a thermoplastic elastic insole. The difference between this embodiment and the first embodiment is that the thermoplastic elastic insole of the present invention is a two-color insole, which includes the cloth 1, the insole body 2 and the small insole 3 from top to bottom; this embodiment The color of the insole body 2 of the thermoplastic elastic insole of the example and the color of the small insole 3 are different. When injecting two-color insoles, it is two injection molding; according to the structural requirements of the insoles, a lower mold and two upper molds are designed. The injection molding process is as follows, such as Figure 4 , 5 Shown:

[0057] a. Ingredients: TPR thermoplastic elastomer and toner, according to the weight ratio of 10000:8 or 10000:12 or 10000:16, it is best to use the weight ratio of 10000:12; send it to the kneader to knead 20 or 30 or 40 minutes, the best kneading time is 30 minutes;

[0058] b. Punching: The fa...

Embodiment 3

[0074] A method for processing a thermoplastic elastic insole. The difference between this embodiment and the second embodiment is that the thermoplastic elastic insole of the present invention is a three-color insole, which includes a cloth cushion 1, an insole body 2, an insole middle piece 4, and an insole small piece 3. Among them, the insole middle piece 4 is provided with a through groove, the insole small piece 3 is located in the through groove of the insole middle piece 4, the insole body 2 is located under the cloth 1, and the insole small piece 3 and the insole middle piece 4 are located under the insole body 2. The color of the insole body 2, the color of the small insole 3, and the color of the middle part of the insole 4 of the thermoplastic elastic insole of this embodiment are all different. When injecting the three-color insole, it is three injection molding; according to the structural requirements of the insole, design a lower mold, two upper molds, and anothe...

Abstract

The present invention discloses a processing method of a thermoplastic elastic insole. A TPR thermoplastic elastomer (thermoplastic rubber) as the main raw material, and the following processing stepsare adopted, firstly, compounding is that the TPR thermoplastic elastomer and toner are compounded according to the weight ratio of 10000 to 8 till 10000 to 16 and are sent into a kneading machine tobe kneaded for 20 to 40 minutes; secondly punching a cloth is that a base material of the cloth is punched and sheared as the shape of a mould of the insole which is needed to for a laying cloth; thirdly injection mold and molding are that at first placing the laying cloth is that the laying cloth is put inside an injection mold and is placed above a lower mold; then feeding is that the well kneaded raw material is put into an injection mold and molding machine, than molding is that the injection mold is sent into the injection mold and molding machine, and the injection mold and molding machine starts to inject towards the injection mold, and the injection temperature is 150 DEG C to 250 DEG C, and injection pressure is 30 bar to 90 bar, and a rotating speed of a screw is 25 to 75 turnsper minute, and a backpressure is 3 bar to 4 bar; fourthly punching a margin is that the insole is taken out from the mold, and the redundant marginal material joints are punched down by a punch; fifthly punching is that exhausting pylomes are punched at the insole. The insole produced by the present invention has good breathability, pliability and rebound resilience.

Description

Technical field [0001] The invention relates to an insole and a processing method, in particular to a thermoplastic elastic insole and a processing method. Background technique [0002] As an important component of shoes, insoles are valued by manufacturers and consumers. Especially sports shoes have higher requirements for insoles. Most of the insoles in the prior art are rubber products, which are generally stamped and formed by plate-shaped materials. Poor air permeability. CN97125817.1 disclosed in the Chinese patent database is an insole with a massage effect and its manufacturing method. The traditional polyurethane foam insole is mixed with waste plastic materials, rubber waste and sawdust, open foaming, so that each foaming monomer Ventilation holes are formed to make the insole have better ventilation, sweat absorption, deodorization, and anti-bacterial effects. The mixed wood chips, plastic and rubber waste materials have a massage effect. The preparation method is to...
