Embodiment 1
[0013] A kind of folding-resistant PVC foam sole material, by weight percentage, raw material ratio is as follows:
[0014]
[0015]
[0016] The preparation method is as follows:
[0017] (1) Accurately weigh according to the formula, fully mix PVC, DOP, and bariumstearate into a drying oven at 100-110°C for pre-plasticization, and stir once every 5 minutes to make DOP completely absorbed by PVC. A pre-plasticized mixture is obtained.
[0018] (2) Put the pre-plasticized mixture into the double-roller plastic mixer (roller temperature is 110-120°C), and after the material is completely wrapped and plasticized, add other additives and mix evenly, and knead to produce tablets.
[0019] (3), take material piece and place in the heating mold of 165 ℃, under 10MPa condition, press to make it foam, and cooling makes the anti-folding PVC foaming sole material of performance excellent.
Embodiment 2
[0021] A kind of folding-resistant PVC foam sole material, by weight percentage, raw material ratio is as follows:
[0022]
[0023] The preparation method is as follows:
[0024] (1) Accurately weigh according to the formula, fully mix PVC, DBP, and bariumstearate into a drying oven at 100-110°C for pre-plasticization, and stir once every 5 minutes to make DBP completely absorbed by PVC. A pre-plasticized mixture is obtained.
[0025] (2) Put the pre-plasticized mixture into the double-roller plastic mixer (roller temperature is 110-120°C), and after the material is completely wrapped and plasticized, add other additives and mix evenly, and knead to produce tablets.
[0026] (3), take material piece and place in the heating mold of 165 ℃, under 10MPa condition, press to make it foam, and cooling makes the anti-folding PVC foaming sole material of performance excellent.

Abstract
The invention discloses a fold resisting PVC (Polyvinyl Chloride) foaming sole material which comprises the following components in percentage by weight: 50-70 percent of PVC resin, 3-10% of a plasticizer, 0.05-2% of a foaming agent, 0.05-3% of a metal salt stabilizer, 10-25% of epoxidized natural rubber and 2-10% of neoprene. The epoxidized natural rubber used by the material disclosed by the invention can better toughen the PVC material, so that the material has better flexibility and bendability. The neoprene is added to improve the strength of the material to a certain extent. The epoxidized natural rubber and the neoprene are jointly used to improve the mechanical properties of the PVC foaming sole material.
Description
Technical field: [0001] The invention relates to the technical field of shoe materials, in particular to a PVC shoe sole material. Background technique: [0002] There are many types of sole materials, which are generally divided into two types: natural sole materials and synthetic sole materials. Natural sole materials include natural bottom leather, bamboo, wood, etc., and synthetic sole materials include rubber, PU materials, PVC synthetic resins, etc. The common characteristics of sole materials are wear resistance, water resistance, good elasticity, easy to fit the foot shape, and not easy to deform after being shaped. Synthetic sole materials are currently the most widely used type of shoe materials. Among the synthetic sole materials, PU material is popular because of its light weight, soft hand feeling and good hand feeling, but its price is more expensive. [0003] PVC has high mechanical strength, good acid and alkali resistance, and its price is far cheaper tha...
