preparation example Construction

[0034] A preparation method of EVA sole material, it may further comprise the steps:

[0035] 1) Take each component material according to the above proportioning ratio;

[0036] 2) Place the weighed graphene in the graphene organic dispersion (GSOS, produced by Ningbo Moxi Technology Co., Ltd.), stir evenly, and ultrasonically vibrate for 30 minutes to prepare the graphene dispersion for subsequent use;

[0037] 3) Stir and mix the other components except azodicarbonamide and dicumyl peroxide and the graphene dispersion at 85-90°C; put it in an internal mixer, add azodicarbonamide , dicumyl peroxide, banburying at 105-110°C for 10-15min;

[0038] 4) After banburying, carry out kneading and granulation, the temperature of said kneading and granulation is 80-85°C;

[0039] 5) Put the pellets in step 4) into a foaming machine for foaming. The foaming temperature is 150-160° C., the pressure is 165kg-175kg, and the foaming time is 5-10 minutes to obtain the shoe sole material. ...

Abstract

The invention relates to an EVA (ethylene vinyl-acetate copolymer) sole material and a preparation method thereof. The EVA (ethylene vinyl-acetate copolymer) sole material consists of the following ingredients in part by weight: 75-85 parts of EVA, 0.2-1 part of graphene, 8-15 parts of calcium carbonate master batch, 3-5 parts of zinc oxide, 0.5-2 parts of zinc stearate, 0.5-2 parts of zinc acetate, 0.5-3 parts of azodicarbonamide and 1.5-3 parts of dicumyl peroxide. Compared with the prior art, the EVA sole material has the advantages that after the graphene is added in the EVA sole material, the sliding resistance of the EVA sole material is improved, and the EVA sole material has high tearing resistance, is not easy to damage and is durable. The wear resistance of the EVA sole material is high even if wear-resisting agents are not added in the EVA sole material, and the wear resistance is improved.

Description

technical field [0001] The invention belongs to the field of shoe sole composite materials, and in particular relates to an EVA shoe sole material and a preparation method thereof. Background technique [0002] Ethylene-vinyl acetate copolymer (EVA) has good plasticity, elasticity and processability, and the foamed material has the advantages of low density, good mechanical properties, and easy coloring. It is widely used in shoe sole materials, but EVA materials The wear resistance of rubber is not as good as that of rubber, it is easy to tear and break, and its anti-skid performance is not good, so its service life is not long, which hinders its application in high-end shoes. Contents of the invention [0003] In view of this, it is necessary to provide a kind of EVA sole material with good anti-skid performance, good mechanical properties and good wear resistance. [0004] In addition, it is also necessary to provide a preparation method of EVA sole material. [0005]...
