Embodiment 1

[0032] A preparation method for casual shoe soles, comprising the following preparation steps:

[0033] S1. Mix 1kg TPR recycled material, 0.3kg polypropylene, 0.2kg thermoplastic styrene-butadiene rubber, 0.001kg cross-linking agent and banbury at 120°C for 15 minutes, then add 0.05kg polyacrylamide and 0.04kg polymethacrylate , 0.01kg amino-modified polyacrylic acid to continue banburying for 5min, and then granulate to obtain pellets;

[0034] S2. Take 0.8 kg of granulated material and heat it to a molten state, then extrude it into a corresponding shoe sole mold and make injection molding to make a casual shoe sole. The injection molding temperature is 180° C., and the mold holding time is 1 second;

[0035] The thermoplastic styrene-butadiene rubber used is a linear structure, the model is LG-604; the polyacrylamide used is anionic polyacrylamide.

Embodiment 2-9

[0037] Embodiments 2-9 are all based on Embodiment 1, and differ from Embodiment 1 only in that the preparation conditions of the soles of casual shoes are different, see Table 2 for details.

Abstract

The invention relates to the technical field of board shoe manufacturing, and particularly discloses a casual shoe sole and a preparation method thereof. The casual shoe sole is prepared from the following raw materials in parts by weight: 80 to 120 parts of TPR reclaimed material, 20 to 40 parts of polypropylene, 15 to 30 parts of thermoplastic styrene-butadiene rubber, 0.05 to 0.15 part of cross-linking agent, 3 to 7 parts of polyacrylamide, 2 to 6 parts of polymethacrylate and 0.5 to 1.5 parts of amino-modified polyacrylic acid. The preparation method comprises the following steps: S1, mixing the TPR reclaimed material, the polypropylene, the thermoplastic styrene-butadiene rubber and the cross-linking agent, conducting banburying, then adding the polyacrylamide, the polymethacrylate and the amino-modified polyacrylic acid, continuously conducting banburying, and conducting granulating to obtain a granulated material; and S2, heating the granulated material to a molten state, and then extruding the molten material into a sole mold for injection molding to obtain the casual shoe sole. The casual shoe sole provided by the invention has better aging resistance under ultraviolet irradiation and is environment-friendly.

Description

technical field [0001] The present application relates to the field of sneaker manufacturing technology, more specifically, it relates to a casual shoe sole and a preparation method thereof. Background technique [0002] The design concept of casual shoes is mainly simple and comfortable, which can meet the needs of people's daily life. With the continuous development of economy and society, people's living standards are gradually improving, so they begin to pursue higher quality of life and life experience. The shape and connotation of casual shoes can meet people's needs and obtain spiritual satisfaction of aesthetic pleasure. [0003] The soles of casual shoes are mostly rubber soles, which are relatively soft and have high elasticity and impact resistance. my country's casual shoes market is huge, and a large number of casual shoes are produced every year, which also produces a lot of scraps and discarded soles of thermoplastic rubber soles. Thermoplastic rubber is gen...
