Embodiment 1

[0033] A kind of wormwood powder shoe material, comprises the raw material of following weight portion:

[0034]

[0035] In this embodiment, the preparation of the polyester prepolymer A includes the following steps: Weighing 1,4-butanediol and succinic acid with a molar ratio of 1.0:1 and mixing them uniformly, under normal pressure nitrogen protection conditions, After raising the temperature to 160°C and stirring for 1 hour, add catalyst A and antioxidant A, continue to raise the temperature to 200°C until almost no water is distilled out, and then gradually reduce the pressure to below 5kPa to carry out polycondensation reaction for 3 hours and then stop the reaction, that is The polyester prepolymer A was prepared.

[0036] The preparation of the polyester prepolymer B comprises the steps of: weighing a short-chain dibasic alcohol and an aliphatic saturated dibasic acid with an alkyd molar ratio of 1.0:1 and mixing them uniformly; After stirring and reacting at 160°C...

Embodiment 2

[0050] A kind of wormwood powder shoe material, comprises the raw material of following weight portion:

[0051]

[0052] In this embodiment, the preparation of the polyester prepolymer A includes the following steps: Weighing 1,4-butanediol and succinic acid with a molar ratio of 1.1:1 and mixing them uniformly, under normal pressure nitrogen protection conditions, After raising the temperature to 170°C and stirring for 1.5 hours, add catalyst A and antioxidant A, continue to raise the temperature to 210°C until almost no water is distilled, and then gradually reduce the pressure to below 5kPa for polycondensation reaction for 4 hours, then stop the reaction. That is, the polyester prepolymer A is obtained.

[0053] The preparation of the polyester prepolymer B comprises the steps of: weighing a short-chain dibasic alcohol and an aliphatic saturated dibasic acid with an alkyd molar ratio of 1.1:1 and mixing them uniformly; Stir and react at 160-180°C for 1.5h, add catalys...

Abstract

The invention particularly relates to a wormwood powder shoe material, which is prepared from the following raw materials in parts by weight: 5 to 20 parts of polyester prepolymer A, 30 to 50 parts of polyester prepolymer B, 15 to 35 parts of ethylene-vinyl acetate copolymer, 4 to 10 parts of wormwood powder, 2 to 7 parts of chain extender, 0.5 to 3 parts of carbon black, 0.6 to 3 parts of water repellent agent, 0.7 to 2.2 parts of antioxidant, 0.6 to 5 parts of cross-linking agent and 0.8 to 3.5 parts of composite foaming agent, the prepared wormwood powder shoe material is a degradable material, cannot pollute the environment after being used, has the characteristics of light weight, flexibility, tensile resistance, good resilience and shock absorption performance, difficulty in water absorption and good antibacterial and deodorizing effects, and is simple in preparation process, controllable in condition, low in cost, high in production efficiency, and the quality of the prepared product is stable.

Description

technical field [0001] The invention relates to the technical field of shoe materials, in particular to a wormwood powder shoe material and a preparation method thereof. Background technique [0002] In recent years, the rapid development of the shoe-making industry has also promoted the continuous innovation of sole materials. Foamed soles have gradually replaced PVC and rubber solid new sole materials. At this stage, the main foamed soles are PE, EVA, SBS and PU. Among them, PE foam soles have good wear resistance and heat insulation, but weak slip resistance and easy deformation; EVA foam soles have good elasticity, strong shock resistance and weather resistance, but low mechanical strength; The foamed sole needs to be modified with other high polymers. For example, the TPR sole material made of it has the characteristics of non-slip and breathable, but the price is relatively high; the PU foamed sole has low density, high strength and good elasticity. , can be adjusted ...
