Embodiment 1

[0027] A kind of shoe sole material of the present invention is mainly formulated by the following raw materials of weight part: the TPU (thermoplastic polyurethane elastomer plastic) of 50 weight parts, the PVC (polyvinyl chloride) of 50 weight parts, the chlorinated polyvinyl chloride of 4 weight parts Ethylene, 20 parts by weight of a plasticizer, 6 parts by weight of a stabilizer, 0.6 parts by weight of a crosslinking agent, 0.2 parts by weight of a lubricant, and 20 parts by weight of a filler.

[0028] Among them, TPU is polyether type, and the hardness of TPU is 75 degrees; PVC is resin powder with grade SG-5, viscosity number 118-107ml / g, K value 68-66, and average polymerization degree 1135-981; Plasticizer is fatty acid butyl ester; Stabilizer is the mixture of calcium-zinc composite stabilizer and barium stearate, and the weight ratio of calcium-zinc composite stabilizer and barium stearate is 2: 1; Cumene; lubricant is PE wax; filler is surface-treated calcium carb...

Embodiment 2

[0046] A kind of shoe sole material of the present invention, its preparation method is the same as embodiment one, compares its difference with embodiment one in formula: this formula is mainly formulated by the raw material of following weight parts: 70 weight parts of TPU (thermoplastic polyurethane elastic body plastic), 30 parts by weight of PVC (polyvinyl chloride), 20 parts by weight of plasticizer, 4 parts by weight of ethylene-vinyl acetate grafted maleic anhydride, 6 parts by weight of stabilizer, 0.3 parts by weight of lubricating agent, 30 parts by weight of the filler.

[0047] Among them, the TPU is polyester type, and the hardness of TPU is 85 degrees; the grade of PVC is SG-5 type, the viscosity number is 118-107ml / g, the K value is 68-66, and the average polymerization degree is 1135-981 resin powder; Plasticizer is triethyl citrate; Stabilizer is the mixture of calcium-zinc composite stabilizer and barium stearate, and the weight ratio of calcium-zinc composi...

Abstract

The invention discloses a sole material. The sole material is characterized in that the sole material is prepared from 50-150 parts of TPU, 10-50 parts of PVC, 10-30 parts of a plasticizer, 3-6 parts of a stabilizer, 2-20 parts of a compatilizer, 0-1 part of a crosslinking agent, 0-50 parts of a filler, and 0-1 part of a lubricant, wherein the compatilizer is one of chlorinated polyethylene and ethylene-vinyl acetate grafted maleic anhydride. According to the invention, after adopting above technical scheme, the compatibility of a blend of the TPU and the PVC is improved, so a problem of bad compatibility of blends treating the TPU as a primary material and the PVC as an auxiliary material in the prior art is solved, thereby the utilization of excellent characteristics of the TPU and the PVC makes the sole material of the invention have the advantages of good wear resistance and low production cost.

Description

technical field [0001] The invention relates to the field of materials, in particular to a shoe sole material and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane elastomer (TPU) is a special material that integrates the high elasticity of rubber and the molding processability of plastic, and has excellent comprehensive properties; compared with other thermoplastic elastomers, TPU has high strength, good toughness, and wear resistance. , cold resistance, oil resistance, acid and alkali resistance, hydrolysis resistance, aging resistance, weather resistance, UV resistance, environmental protection and other excellent performances, it is widely used in industry, automobile manufacturing, footwear, wire and cable and other fields, but TPU also exists Narrow processing temperature range, difficult molding processing, high production cost, difficult hardness adjustment, poor heat resistance and other defects, these defects limit the further p...
