Embodiment 1

[0056] A process for processing shoe outsoles with an injection pressure structure, which is carried out in accordance with the following sequence of steps:

[0057] (1) Preparation before injection

[0058][Preparation of rubber cleaning agent A] Prepare RS-type cleaning agent and water according to the ratio of 2:100;

[0059] [Preparation of treatment agent C] Prepare according to the ratio of RS-601 type treatment agent: RFE type reinforcing agent: rubber powder = 100:5:3.

[0060] (2) Cleaning of the rubber sole

[0061] Heat the rubber cleaning agent A to 50°C, and put it into the rubber sole for cleaning. The purpose is to remove oil stains, mold release agents and waxy fatty substances on the surface of the rubber sole that hinder the bonding, which is conducive to bonding. The rubber sole is soaked for 4 minutes, and then removed.

[0062] (3) Once dried

[0063] Put the cleaned rubber sole into an oven for a drying treatment, the drying temperature is 50°C, and t...

Embodiment 2-5

[0078] Embodiments 2-5 are respectively a shoe outsole processing technology with an injection pressure structure, and the process steps are similar to those in Embodiment 1, the only difference being the test parameters involved therein and the test results of the bonding strength, as shown in the following table:

Abstract

The invention discloses a process for processing the outsole of an injected and molded structure. The outsole of the injected and molded structure, which is processed by adopting the process, has the characteristics of firm combination of the rubber and the PU (polyurethane) and good stability and repeatability and is suitable for batch production. The process is simple, has low cost and adopts of the flow of detecting the bonding strength according to the measurement of the bonding strength of vulcanized rubber or thermoplastic rubber and fabric of GB / T532-1997. The bonding strength between the rubber and the PU of the outsole is equal to or more than 100N / mm. The process is suitable for processing the outsole of the injected and molded structure.

Description

Technical field [0001] The present invention is a shoe -making field, involving the processing process of the shoe outsole, and specifically the shoe outsole processing process of the structured structure. Background technique [0002] At present, most of our domestic manufacturers of reasons structure shoes are mostly the following two types of soles: 1. The outer layer is PU, the foam layer is PU; 2.PU is polymethlate; TPU is a thermoplastic polyurethane elastic body plastic.Because rubber has good abrasion resistance, aging and stability, the outsole produced by rubber and PU injection technology can be widely used in labor -friendly shoes, military shoes, mid -to -high -end sneakers and outdoor shoes.However, it is difficult to bonding between rubber and PU. Most domestic manufacturers are distressed by the combination and intensity of rubber and PU. [0003] China Practical New Patent CN201929132U revealed a "PU and Rubber -density injection shoes". Among them, the upper is ...
