Problems solved by technology

[0003] However, during the production of the existing soles, due to the characteristics of the rubber material, the wear resistance is poor, and because the heat resistance is poor, and the thermal conductivity of the rubber itself is poor, it is easy to cause the external rubber to deteriorate and become brittle, and it is easy to dry and crack, which affects the use. life and stability, so a new production process is to be proposed

[0037] As preferably, the preparation method of described rubber material comprises the steps:

[0038] P1. Weigh a raw material according to the mass percentage and set aside;

[0039] P2. Put the natural rubber and the rubber into the mixing agent after being pulverized, and stir evenly for 10 to 20 minutes to obtain the mixed rubber;

[0040] P3. Put the crosslinking agent into the mixed rubber, stir evenly and let it stand for 30 to 40 minutes, then put in stearic acid and anti-aging agent;

[0041] P4. Put the reinforcing agent into the mixed rubber, heat it to a molten state, extrude and granulate, and then the anti-aging rubber can be obtained.

[0042] Preferably, the degreasing treatment in the P2 step also includes vacuuming and uniform stirring, and the vacuum state is 30KPa to 40KPa.

[0043] Preferably, the mass percentage of zinc oxide powder and rubber material in the P3 step is 1:25-30.

[0044] Preferably, the injection molding temperature of the P6 step is...

Embodiment 1

[0048] A kind of sole production process, this production process comprises the steps:

[0049] P1, select the rubber material according to the mass percentage, and set aside;

Abstract

The invention discloses a shoe sole production process. The shoe sole production process comprises the following steps that P1, a rubber material is selected according to mass percent for later use; P2, a degreased material is obtained; P3, a mixed raw material is obtained; P4, a crushed material is formed; P5, the crushed material is put into a melting furnace again, and heating is carried out toa molten state to obtain a uniform material; P6, a shoe sole blank is obtained; P7, a finished blank is obtained; and P8, the finished blank is put into a constant-temperature chamber, heat preservation is carried out to 30 DEG C-35 DEG C, constant-temperature shaping is carried out, constant-temperature shaping lasts for 24 hours-36 hours, and production of the shoe sole can be completed. Zinc oxide powder is added to the interior of the rubber material, then secondary smashing and melting are carried out, the mixing uniformity can be effectively improved, the wear resistance and heat resistance of the shoe sole are further enhanced, hardening and embrittlement are avoided, the product quality is improved, meanwhile, by adopting a reasonable proportion, the structural performance is enhanced, the anti-aging capacity is high, the production is facilitated, and the popularization and the use are convenient.

Description

technical field [0001] The invention relates to the technical field of shoe soles, in particular to a shoe sole production process. Background technique [0002] In the limited daily life, people pay more and more attention to comfort when wearing shoes. Therefore, rubber soles are very popular because of their light weight and good softness. [0003] However, during the production of the existing soles, due to the characteristics of the rubber material, the wear resistance is poor, and because the heat resistance is poor, and the thermal conductivity of the rubber itself is poor, it is easy to cause the external rubber to deteriorate and become brittle, and it is easy to dry and crack, which affects the use. Life and stability, so a new production process needs to be proposed. Contents of the invention [0004] The object of the invention is to propose a shoe sole production process in order to solve the shortcomings in the prior art. [0005] In order to achieve the ab...
