Embodiment 1

[0040] The composition and weight ratio of A raw material are as follows:

[0041]

[0042] The production method of A raw material is as follows:

[0043] First, heat the reaction tank to 80°C and keep it for 1 hour to dry it;

[0044] Next, add polyester polyols of different molecular weights and cell openers in the raw material A above into the reaction tank according to the ratio, and stir evenly for 90 minutes. The temperature of the reaction tank is controlled between 80°C and 100°C;

[0045] Finally, after cooling the reaction tank to 50°C, put material B into the material tank and seal the material.

[0046] The composition and weight proportion of described B raw material are as follows:

[0047] Polyester polyol 30%;

[0048] Isocyanate 70%;

[0049] The molecular weight of described polyester polyol is 3000, and B raw material composition preparation method is as follows:

[0050] First, heat the reaction tank to 80°C and keep it for 1 hour to dry it;

[00...

Abstract

The invention discloses a preparation method for a chronic springback resin material used for a shoe sole. In the preparation method, the material is prepared from A and B raw materials, the A raw material comprises polyester polyol and an opening agent, the B raw material comprises polyisocyanate, and the reaction mole ratio of the A raw material to the B raw material is 1:1-5. The prepared chronic springback resin material has good tension, damping and ventilating effects, and is suitable for shoe sole products. Good protection is provided for feet of users, and comfortable wearing effects are provided.

Description

Technical field: [0001] The invention relates to the technical field of resin products, in particular to a preparation method of a slow rebound resin material used for shoe soles. Background technique: [0002] Resin materials are widely used in people's daily life. With the development of technology, resin materials with shape memory have appeared. The so-called memory resin material is: the polymer material is endowed with a certain shape under certain conditions. When the external conditions change, it can change the shape accordingly and fix it. Once a change occurs, the shape memory polymer reversibly returns to its original state. Most of the polymers used in the above-mentioned shape memory polymer materials are resins, so they are called memory resins. [0003] At present, the application of memory resin is mainly in related products that interact with the human body, such as pillows, cushions, etc., and can also be used as equipment for fixing wounds, replacing tr...
