Embodiment 1
[0060]A kind of highly elastic sole, its preparation method comprises the following steps:
[0061] (1) 70kg of polyoxypropylene glycol with a number average molecular weight of 600g / mol, 12kg of ethylene glycol, 5.2kg of cyclohexanehexaphosphoric acid, 1.2kg of tris[2.4-di-tert-butylphenyl]phosphite and Mix 2.2kg of water evenly to prepare material A;
[0062] (2) Inject 75kg of material A and 25kg of material B into the mold, treat at a temperature of 115°C for 10 minutes, and then cool and form the inner bottom in the mold; in this example, material B uses diphenylmethane diisocyanate;
[0063] (3) Bonding and fixing the inner sole to the outer sole to obtain the sole.
Embodiment 2
[0065] A kind of highly elastic sole, its preparation method comprises the following steps:
[0066] (1) 75kg of polytetramethylene ether glycol with a number average molecular weight of 2000g / mol, 14kg of diethylenetriamine, 6.2kg of cyclohexanehexaphosphoric acid, and 1.8kg of tris[2.4-di-tert-butylphenyl] Phosphite and 2.7kg of water were uniformly mixed to prepare material A;
[0067] (2) Inject 80kg of material A and 20kg of material B into the mold, treat at 120°C for 8 minutes, and then cool and form the inner bottom in the mold; in this example, material B uses diphenylmethane diisocyanate;
[0068] (3) Bonding and fixing the inner sole to the outer sole to obtain the sole.
Embodiment 3
[0070] A kind of highly elastic sole, its preparation method comprises the following steps:
[0071] (1) 80kg of polytetramethylene ether glycol with a number average molecular weight of 2000g / mol, 8kg of diethylenetriamine, 8kg of ethylene glycol, 7.4kg of cyclohexanehexaphosphoric acid, 2.6kg of three [2.4-ditertiary Butylphenyl] phosphite and 3.2kg water are uniformly mixed to obtain material A;
[0072] (2) Inject 85kg of material A and 15kg of material B into the mold, treat it at a temperature of 125°C for 7 minutes, and then cool it in the mold to form an inner bottom; in this example, material B uses hexamethylene diisocyanate;
[0073] (3) Bonding and fixing the inner sole to the outer sole to obtain the sole.

Abstract
The invention relates to the field of soles, and particularly discloses a high-elasticity sole and a preparation method thereof. The high-elasticity shoe sole comprises an outer sole and an inner sole, and the inner sole is prepared from the following raw materials in parts by weight: 75-85 parts of a material A and 15-25 parts of a material B; the material A comprises polyether polyol, a chain extender, a raw material, inositol hexaphosphate, tris [2.4-di-tert-butylphenyl] phosphite, water and the like; the material B is isocyanate; the preparation method comprises the following steps: preparing the material A; injecting the material A and the material B into a mold according to the weight ratio and treated at the temperature of 115-125 DEG C for 7-10 min, and then forming the inner sole in the mold in a cooling mode; and fixing the inner sole into the outer sole. The insole of the shoe sole has good elastic performance, the yellowing resistance and the degradation performance are obviously improved, the service life of the insole is prolonged, and meanwhile pollution of the insole to the environment is reduced.
Description
technical field [0001] The present application relates to the field of shoe soles, more specifically, it relates to a highly elastic shoe sole and a preparation method thereof. Background technique [0002] Shoes generally include soles and uppers, which are necessities that everyone cannot do without. Wherein, the sole usually includes an outer sole and an inner sole. The outer sole is made of a wear-resistant and non-slip rubber material, while the inner sole is generally made of a highly elastic material in order to improve the wearer's experience. [0003] At present, the inner bottom in the related art is generally made of TPR thermoplastic rubber or PU polymerpolyurethane material. Wherein, the inner bottom made of TPR thermoplastic rubber is translucent, and has better elasticity and wear resistance, but the inner bottom made of TPR thermoplastic rubber is relatively heavy in weight, and is easy to turn yellow. The inner bottom made of PU polymerpolyurethane mater...
