Embodiment 1

[0022] The invention discloses a method for making shoe soles from leather waste. The raw materials include leather waste, rubber and thermoplastics. The production steps are as follows:

[0023] Step 1: Classifying and splitting the leather waste according to the color, and grinding the obtained leather waste to obtain leather powder for later use; grinding thermoplastics to obtain thermoplastic fragments for later use;

[0024] Step 2: Mix leather powder, rubber and thermoplastic fragments evenly, put them into a milling machine for milling, and obtain the basic material;

[0025] Step 3: Put the basic material in step 2 into the mold frame for cutting and processing, then put it into the mold and send it to the forming machine for die-casting to obtain the finished product.

[0026] As a preferred technical solution of the present invention, in the first step, the grinding size of the leather powder is 0.2 mm; the grinding size of the thermoplastic fragments is 0.5 mm.

Abstract

The invention discloses a method for making a sole by using leather waste. The method comprises the following steps: grinding the leather waste, rubber and thermoplastic, mixing, milling in a milling machine, finally adding into a mold, and carrying out die-casting formation. Compared with the prior art, the method has the beneficial effects that the leather waste and the recyclable thermoplastic plastic are ground, mixed and milled to obtain a mixture capable of being directly molded, and meanwhile, die casting or injection molding can be directly used for production without an adhesive, so that the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of shoe sole production, in particular to a method for making shoe soles from leather waste. Background technique [0002] Due to the development of the garment industry, there are more and more waste materials from shoe factories and garment factories, including cloth, leather waste, leftovers, and leftovers. As well as the waste luggage, purses, cloth bags, canvas bags, etc. discarded in daily life, if they are directly incinerated by garbage dumps, they will cause air pollution. In order to effectively utilize renewable resources, it is necessary to collect and store waste and leftover materials for recycling and reuse. [0003] Chromium-containing solid waste Cr3-4%, Pr>90%, because the waste contains chemical elements such as N, P, S, K, Ca, Mg, Cr, Fe, Al, etc., the fertilizer made in this way can increase rice production by 18%, Wheat production increased by 36%. The meatless residue (the more o...
