example 1

[0018] Step 1: pour the PU material with anti-slip effect into the mold and clean it, and then pressure-bond it with textiles (such as non-woven fabrics) in a semi-cured state, and finally solidify the PU material on the textile to form Preliminary soles. The blank of the sole will be the anti-skid bottom layer of the final shaped sole. In order to improve the anti-slip effect, evenly distributed granular protrusions or concave-convex patterns with anti-slip function are formed on the blank of the sole and bonded to the textile side. Specifically, through the cavity formed on the mold, the plasticity of the PU material is used to form by pressing.

[0019] Step 2, and then the TPU film is bonded to the side of the above-mentioned shoe sole blank without textiles by hot pressing to form the shoe sole blank.

[0020] Step 3. Finally, place the above-mentioned shoe sole blank on the shoe sole mold, and then pour liquid PU into the shoe sole mold. The liquid PU will combine with...

[0022] Step 1: pour the anti-slip PU material into the cavity of the mold, clean it, and after curing and forming, spray or bond the liquid TPU or TPU film to one of the surfaces of the above-mentioned formed PU material;

[0023] Step 2, place the PU material obtained above in the mold, after heating, put textiles, leather or artificial leather into the mold in the semi-cured state of the PU material, and combine it with the above-mentioned side without the TPU material, press the The two are bonded, so that the PU material is cured and formed on textiles, leather or artificial leather to form a blank for the sole;

[0024] Step 3. Finally, place the above-mentioned sole blank in the sole mold, and then pour liquid PU into the sole mold. The liquid PU will combine with the TPU material on the sole blank, solidify and form, and form the sole.

[0029] Step 1: Pour the PU material with anti-slip effect into the mold and clean it, then pressure-bond it with leather or artificial leather in a semi-cured state, and finally solidify the PU material on the leather or artificial leather to form a shoe sole Blank. The blank of the sole will be the anti-skid bottom layer of the final shaped sole. In order to improve the anti-slip effect, evenly distributed granular protrusions or concave-convex patterns with anti-slip function are formed on the blank of the sole and bonded to the textile side. Specifically, through the cavity formed on the mold, the plasticity of the PU material is used to form by pressing.

[0030] Step 2, then bonding the TPU film to the side of the above-mentioned shoe sole blank without leather or artificial leather through hot pressing to form the shoe sole blank.

[0031] Step 3. Finally, place the above-mentioned shoe sole blank on the shoe sole mold, and then pour liquid PU into the shoe sole mold. ...

Abstract

The invention relates to the technical field of sole manufacturing methods, and specially relates to a manufacturing method of an anti-slip sole. The manufacturing method comprises the following steps of 1, carrying out a hot pressing process on a polyurethane (PU) material and a textile, leather or artificial leather to cure and mold the PU material on the textile, the leather or the artificial leather to obtain a sole initial blank, 2, spraying liquid thermoplastic urethane (TPU) on or bonding a TPU film to a side of the sole initial blank to obtain a sole blank, wherein there is not the textile, the leather or the artificial leather on the side, and 3, putting the sole blank obtained from the step 2 into a sole mould, pouring liquid PU into the sole mould to make the liquid PU combine with TPU on the sole blank, and carrying out a curing and molding process to obtain a finished sole. A sole produced through the manufacturing method has three layers, and textile, leather or artificial leather located at the bottom layer and a thin PU layer are combined together by being cured to form an anti-slip part located at the bottom of the sole. TPU can be combined well with PU of a main part located at the top layer of the sole thus the anti-slip sole is formed finally.

Description

technical field [0001] The invention relates to the technical field of shoe sole manufacturing methods, in particular to a manufacturing method of non-slip shoe soles. Background technique: [0002] If the general sole has textiles, leather or artificial leather at the bottom, there is no attachment on the textile, leather or artificial leather, or the attachment is rubber, EVA rubber-plastic products or thermoplastic rubber. And usually when there are textiles, leather or artificial leather under the sole, they are all bonded together with glue or connected by sewing, which not only has high production cost but also has many disadvantages. At the same time, it will cause environmental pollution. [0003] PU material is the abbreviation of Polyurethane, and the Chinese name is polyurethane for short. Because, simply modify the formula, you can get different density, elasticity, rigidity and other physical properties. So PU materials have been applied in different fields. ...
