Abstract

The invention discloses a laminating popcorn polyurethane shoe material which comprises a PU base layer, a plurality of TPU popcorn foaming granules evenly mixed in the PU base layer, and a TPU protective base film covering the outer surface of the PU base layer. The invention further discloses a production technology of the laminating popcorn polyurethane shoe material. The TPU protective base film is additionally arranged on the original PU base layer in a laminating mode, and in the shoe material foaming forming process, the TPU popcorn foaming granules and the TPU protective base film have the excellent intermolecular binding force, so that the laminating difficulty of the TPU protective base film is lowered, the firmness degree is increased, the TPU popcorn foaming granules are effectively prevented from making contact with water or steam in air by firmly and additionally arranging the TPU protective base film, an effective hydrolysis reaction between the TPU popcorn foaming granules and a polyurethane mixture material can be prevented, and then the service life of the shoe material product is prolonged.

Description

technical field [0001] The invention relates to a shoe material and a preparation process thereof, in particular to a film-coated popcorn polyurethane shoe material and a production process thereof. Background technique [0002] With Beijing's successful bid to host the 2008 Olympic Games, more and more Chinese people are keen on various sports, and high-performance sports shoes have become a hot commodity. As the fourth-generation sole material after rubber, PVC, and SBS, TPU (thermoplastic polyurethane elastomer) has better elasticity, wear resistance, tear resistance, and bending properties, and is a variety of special shoes with extremely high requirements. It is one of the preferred materials for soles of football shoes, skate shoes, hiking shoes, etc. [0003] At present, the materials used for the production of sports shoe soles mainly include PVC, PU, ​​EVE and TPU. Among them, TPU has begun to emerge due to its outstanding performance and environmental protection c...
