Embodiment 1

[0022] A kind of high elasticity glue for shoe sole, it is made by the raw material of following weight part:

[0023] 45 parts of natural rubber, 45 parts of synthetic rubber, 45 parts of white carbon black, 6 parts of naphthenic oil, vulcanization activator, 5 parts of zinc oxide, 1.2 parts of stearic acid, 2 parts of vulcanization accelerator TT (the same below), anti-fog 0.5 parts of agent, 2 parts of sulfur.

[0024] First, the natural rubber is masticated on the open mill to obtain the masticated rubber; then the synthetic rubber, white carbon black, and active agent are put in for banburying for 1 minute; then other raw materials are put into the mixing for 4 minutes, and the sheet is produced; the obtained The sheet rubber is vulcanized at 150° C. for 3.5 minutes under a pressure of 20 MPa, and molded into the high-elastic sole.

[0025] The sole can resist bending for 120,000 times, has an elastic modulus of 0.0080GPa, and a Poisson's ratio of 0.493.

Embodiment 2

[0027] A kind of high elasticity glue for shoe sole, it is made by the raw material of following weight part:

[0028] 40 parts of natural rubber, 40 parts of synthetic rubber, 40 parts of white carbon black, 6.5 parts of naphthenic oil, 4.5 parts of vulcanization activator, 4 parts of zinc oxide, 1.0 part of stearic acid, 1.8 parts of vulcanization accelerator, and 0.3 parts of antifogging agent , 1.0 parts of sulfur.

[0029] First, the natural rubber is masticated on the open mill to obtain the masticated rubber; then the synthetic rubber, white carbon black, and active agent are put in for banburying for 1 minute; then other raw materials are put into the mixing for 4 minutes, and the sheet is produced; the obtained The sheet rubber is vulcanized at 145° C. for 3 minutes under a pressure of 20 MPa, and molded into the high-elastic sole.

Embodiment 3

[0031] A kind of high elasticity glue for shoe sole, it is made by the raw material of following weight part:

[0032] 50 parts of natural rubber, 50 parts of synthetic rubber, 50 parts of white carbon black, 7 parts of naphthenic oil, 5 parts of vulcanization activator, 5.5 parts of zinc oxide, 1.5 parts of stearic acid, 2.5 parts of vulcanization accelerator, 0.6 parts of antifogging agent , 2.5 parts of sulfur.

[0033] First, the natural rubber is masticated on the open mill to obtain the masticated rubber; then the synthetic rubber, white carbon black, and active agent are put in for banburying for 2 minutes; then other raw materials are put into the mixing for 5 minutes, and the sheet is produced; the obtained The sheet rubber is vulcanized at 155° C. for 4 minutes under a pressure of 20 MPa, and molded into the high-elastic sole.

Abstract

The invention belongs to the technical field of shoemaking, and particularly relates to a high-elasticity rubber for shoe soles and a preparation method thereof. The high-elasticity rubber is prepared from the following raw materials in parts by weight: 40-50 parts of natural rubber, 40-50 parts of synthetic rubber, 40-50 parts of silica white, 6-7 parts of naphthenic oil, 1.5-2.5 parts of sulfur, 4-5 parts of cure activator, 1.8-2.5 parts of vulcanization accelerator, 4-6 parts of zinc oxide, 1.0-1.5 parts of stearic acid and 0.3-0.8 part of antifogging agent. The high-elasticity rubber for shoe soles has the advantages of scientific formula, low cost, simple preparation technique and favorable elasticity, and is very comfortable when being used for shoe soles.

Description

[0001] technical field [0002] The invention belongs to the technical field of shoemaking, and in particular relates to a high-elastic glue used for shoe soles and a preparation method thereof. Background technique [0003] Shoes are requisite daily necessities in people's daily life. The comfort and service life of shoes are largely related to the material and performance of the sole. The material of the sole is currently in the majority of rubber soles. Such as ordinary rubber bottom, hot compression molding, divided into natural rubber and recycled rubber. Although it has good wear resistance, non-slip, elastic, not easy to break, good softness, good extensibility, stable shrinkage, good hardness, good bendability, and waterproof. But the disadvantages are heavy weight, easy to spit frost, not easy to corrode; not hard, easy to be pierced; poor air permeability and hygroscopicity, afraid of oil soaking, so it is not suitable to wear in places exposed to oil such as au...
