Embodiment Construction

[0026] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0027] like figure 1 As shown, it is the structural representation of the first embodiment of the sole produced by the production process involved in the present invention, which includes a transparent CPU material 1 and some etpu particles 2 embedded in the CPU material 1, each etpu particle 2 is surrounded by Filled with CPU material 1.

[0028] please cooperate figure 1 and Figure 4 Shown, the present invention relates to a kind of production technology of CPU and popcorn compound transparent sole, comprises the steps:

[0029] 1. etpu granules 2 are placed in the forming mold, the forming mold has an upper mold 61, a lower mold 62 and a cavity 63 between the upper mold 61 and the lower mold 62, and the etpu granules 2 are filled to 1 / 2 -3 / 4 cavity 63 area;

[0030] 2. Pouring the CPU liquid in the cav...

Abstract

The invention discloses a production process for CPU and popcorn compound transparent soles. The production process comprises the following steps: (1) etpu particles are put in a forming mold; the forming mold is provided with an upper mold, a lower mold, and a molding cavity between the upper mold and the lower mold; and the etpu particles are fully filled in 1 / 2-3 / 4 of the area of the molding cavity; (2) CPU liquid is cast in the molding cavity of the forming mold, and is permeated in gaps between adjacent etpu particles to totally cover the upper surfaces of the etpu particles on the uppersurface layer; and (3) the upper mold moves to a preset position, and the etpu particles and the CPU liquid are heated and pressed; exhaust holes are formed around the lower mold; and the upper mold communicates with vacuumizing equipment for forming the CPU and popcorn compound transparent soles. Compared with the prior art, the production process has the characteristics of low mass and obvious etpu particle feeling.

Description

technical field [0001] The invention relates to the field of shoe soles, in particular to a production process of a CPU and popcorn composite transparent shoe sole. Background technique [0002] Due to the unique high-quality performance of TPU materials, the application of TPU materials as shoe soles has developed by leaps and bounds in the past two years. In addition to its unique performance, the aesthetic appearance of shoe materials is also a very distinctive aspect of the shoe material field. [0003] The existing etpu popcorn soles on the market are generally divided into two types, one is to use etpu particles to form a shock-absorbing sheet after steam foaming in a mold, and then apply a layer of glue on the bottom of the shock-absorbing sheet , and connect the upper layer of rubber layer through the glue layer, thus forming a sole with better performance in terms of wear resistance, anti-skid and shock absorption. The other is a shock-absorbing midsole that uses e...
