Problems solved by technology

[0003] At present, the non-foaming TPU on the market is not used alone as the material of the sole, but as an auxiliary material for the sole, which generally plays a role of support and reinforcement or appearance for the shoe, similar to decoration; while the TPU material on the market is The midsole of the foam molding material (E-TPU) is mainly BOOTS material, but its preparation process has limitations, and the cost performance is not high. At the same time, the appearance of the particles is relatively simple, which also brings aesthetic fatigue.

preparation example Construction

[0045] The present invention also provides a method for preparing a shoe midsole material with natural light transmission described in the above technical solution, comprising the following steps:

[0046] a) After premixing the components in the thermoplastic polyurethane elastomer mixture, drying and dehumidifying to obtain a premix;

[0047] b) The premixed material obtained in step a) is sequentially subjected to extrusion foaming, injection foaming and molding, and after adding air holes, a shoe midsole material with natural light transmission is obtained; the extrusion foaming method is super Critical foaming.

[0048] In the invention, firstly, each component in the thermoplastic polyurethane elastomer mixture is premixed, and then dried and dehumidified to obtain the premix. In the present invention, the thermoplastic polyurethane elastomer mixture material is the same as that in the above technical solution, and will not be repeated here.

[0049] In the present inv...

Abstract

The invention provides a shoe midsole material with natural light transmission, which is prepared from a thermoplastic polyurethane elastomer mixture; the thermoplastic polyurethane elastomer mixture comprises the following components: 100 parts by weight of a thermoplastic polyurethane elastomer main material 1-2 parts by weight of nucleating agent; 0.5-1.5 parts by weight of flow agent; 0.2-0.8 parts by weight of anti-yellowing agent; 1-1.5 parts by weight of foaming agent. Compared with the prior art, the shoe midsole material with natural light transmission provided by the present invention adopts specific content components to achieve better interaction, and the prepared shoe midsole material has natural light transmission, and then can obtain Irreplaceable appearance texture and peculiar landscape under light perception. At the same time, the product has excellent low temperature resistance and compression resistance, and high cost performance.

Description

technical field [0001] The invention relates to the technical field of shoe manufacture, and more specifically relates to a shoe midsole material with natural light transmission and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane elastomer (Thermoplastic Urethane, referred to as TPU) is composed of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) and macromolecular polyols, low molecular polyols (chain extenders) A polymer material polymerized by co-reaction; its molecular structure is a rigid block obtained by reacting diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with a chain extender and diphenylmethane diisocyanate (MDI) Or toluene diisocyanate (TDI) and other diisocyanate molecules and flexible chain segments obtained by the reaction of macromolecular polyols are formed alternately. It has excellent high tension, high tensile strength, toughness and aging resistance....
