Embodiment Construction

[0036] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0037] refer to figure 1 , figure 2 and image 3 . A PU popcorn sole, comprising a midsole shoe material 1 and a shoe outsole 2, the midsole shoe material 1 comprising a PU base layer 10 and a plurality of TPU popcorn foam particles evenly mixed in the PU base layer 10 11. Wherein, the TPU popcorn foamed particles 11 are spherical or ellipsoidal. The diameter of the TPU popcorn foamed particles 11 is 30 μm˜300 ​​μm. By setting and mixing TPU popcorn particles into the existing PU raw materials, the existing PU production process is adopted, so that the prepared PU soles are evenly mixed with TPU popcorn particles, thereby effectively improving the existing PU soles. Performance improvement can effectively improve the softness of PU soles, making them lighter in weight and more breathable, making them have the advantages of both PU soles and new TPU...

Abstract

A PU puffed sole comprises an insole and an outsole. The insole comprises a PU base layer and a plurality of TPU puffed grains which are uniformly arranged in the PU base layer. The invention further discloses a production process of the PU puffed sole. The PU puffed sole is simple in structure and high in practicability, As TPU puffed grains are mixed into conventional PU raw material, the PU soles produced by the prior PU production technology is provided with the TPU puffed grains uniformly, performance of the PU soles produced by the prior art are improved effectively, softness of the PU soles is improved effectively, and the PU soles are lighter and more breathable have both advantages of the conventional PU soles and the novel TPU foamed soles; meanwhile, energy consumption and cost can be reduced as manufacturers do not need to purchase novel machines in production; and further, color and style of soles can be increased.

Description

technical field [0001] The invention relates to a shoe material and a preparation process thereof, in particular to a PU popcorn sole and a PU popcorn shoe material preparation process. 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 concept. The ...
