Embodiment 1

[0042] A processing method for thermoplastic elastic insoles, selects TPR thermoplastic elastomer (thermoplastic rubber) as the main raw material, TPR thermoplastic elastomer is to contain styrene-ethylene / butylene-styrene (SEBB) polymer as the main raw material, and naphthene It is made by mixing oil and other polymers (such as PP) in a certain proportion. The processing method adopts the following processing steps, as shown in Figures 1 and 2:

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

[0044] b. Cloth punching: the cloth base material is punched and cut into the shape of the insole mold required to form the pad cloth 1 (consistent with the shape of the insole). The cloth base material in this embodiment is a composite cloth, which is made of one layer of velvet and a white pa...

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 an insole 1, an insole body 2 and a small insole 3 from top to bottom; this embodiment The shoe-pad body 2 color of the thermoplastic elastic insole of example is different from the shoe-pad small piece 3 colors. When injecting two-color insoles, it is two injection moldings; according to the structural requirements of the insoles, a lower mold and two upper molds are designed. The injection molding process is as follows, as shown in Figures 4 and 5:

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

[0058] b. Cloth punching: the cloth base material is punche...

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, including a pad 1, an insole body 2, a middle insole 4 and a small insole 3, Among them, the insole middle part 4 has a through groove, the insole small part 3 is located in the through groove of the insole middle part 4, the insole body 2 is located under the pad cloth 1, the insole small part 3 and the insole middle part 4 are located under the insole body 2 ; The thermoplastic elastic insole of the present embodiment has 2 colors of the insole body, 3 colors of the small insole, and 4 colors of the middle part of the insole. When injecting three-color insoles, it is three-time injection molding; according to the structural requirements of the insole, design a lower mold, two upper molds, and another set of middle molds; the injection molding process is as foll...

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 steps are 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 to be 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 turns per 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 for sports shoes, which have higher requirements for insoles. Most of the insoles in the prior art are rubber products, which are usually stamped and formed by plate materials. Poor air permeability. CN97125817.1 disclosed in the Chinese patent database is a kind of insole with massage effect and its manufacturing method. The traditional polyurethane foam insole is used to mix waste plastic material, rubber waste and sawdust, and open foaming, so that each foaming monomer All of them form ventilation holes, which make the insole more breathable, sweat-absorbing, deodorizing, and anti-bacterial effects, and the wood chips, plastic and rubber waste mixed in it have a massage effect. The productio...
