preparation example Construction

[0040] A preparation method for an anti-slip and wear-resistant shoe material, comprising:

[0041] Preparation steps of anti-slip masterbatch: uniformly mix the anti-slip agent and TPU granules in the formula amount, granulate, and obtain anti-slip masterbatch;

[0042] Preparation steps of wear-resistant masterbatch: uniformly mix the wear-resistant agent and TPU particles in the formula amount, granulate, and obtain wear-resistant masterbatch;

[0043] Mixing and drying step: mix the TPU main material, color masterbatch, anti-slip masterbatch, wear-resistant masterbatch and additives evenly, dry and dehumidify, and obtain the mixed material;

[0044] Casting step: Send the mixed material to the hopper of the casting machine. After the mixed material is heated by the five heating zones, the connecting zone and the screen changing zone of the casting machine, a molten TPU mixture is obtained, and the molten TPU mixture is passed through the casting process. Die extrusion to ...

Abstract

The invention discloses an antiskid wear-resistant shoe material which is prepared from a TPU main material, color master batch, antiskid master batch, wear-resistant master batch and an assistant ina weight ratio of (80-90): (2-7): (2-7): (2-5): 2, wherein the antiskid master batch is prepared from an anti-slip agent and TPU particles in a weight ratio of (3-5): (5-7), the wear-resistant masterbatch is prepared from a wear-resistant agent and TPU particles in a weight ratio of (1-9): (1-13). The shoe material has slip-limiting and wear-resistant functions simultaneously and can replace theprocessing technology that various shoe soles such as a rubber outsole, a TPR shoe sole piece, a TPU shoe sole piece and an EVA shoe sole piece need to be bonded with an insole in the existing composite shoe material and is integrally formed and avoids the degumming risk between the insole and the outsole. The invention further provides a preparation method of the antiskid wear-resistant shoe material. The antiskid wear-resistant shoe material is directly prepared by adopting a tape casting method, the operability of the process is high and industrialization is facilitated.

Description

technical field [0001] The invention relates to the technical field of shoe materials, in particular to a non-slip and wear-resistant shoe material and a preparation method thereof. Background technique [0002] TPU (Thermoplastic polyurethanes) is called thermoplastic polyurethane elastomer rubber. It is divided into polyester type and polyether type. It has a wide range of hardness (60A-85D), wear resistance, oil resistance, transparency, and good elasticity. It is used in daily necessities, sporting goods, It is widely used in toys, decorative materials and other fields. TPU can be used in the manufacture of footwear, such as softball shoes, baseball shoes, golf shoes, football shoe soles and forefoot, and can also be used in the production of ladies' heels, ski boots, safety boots and high-end soles. [0003] Composite soles generally include components such as outsoles, midsoles, and heels. Existing TPU soles need to be made of TPU shoe materials to make midsoles, and...
