Abstract
The present invention discloses a shock-absorbing EVA material and a production method thereof. The shock-absorbing EVA material comprises an EVA shock-absorbing glue, a foaming agent ADC, a bridging agent DCP, and zinc oxide. The method of the present invention has characteristics of simple process and easy operation. The product of the present invention has excellent shock absorption performance, wherein the rebound resilience is less than 15%.
Description
Technical field
The present invention relates to a kind of shock-absorbing EVA material and production method thereof.
Background technology
There is the not good defect of shock-absorbing performance in existing material for sole of shoe, need to improve.
Summary of the invention
The object of the present invention is to provide a kind of shock-absorbing performance good shock-absorbing EVA material and production method thereof.
Technical solution of the present invention is:
A kind of shock-absorbing EVA material is characterized in that: the raw material by following weight part forms:
100 parts, EVA shock-absorbing glue
2 ~ 4 parts of whipping agent ADC
0.2 part of bridging agent DCP
1 ~ 2.5 part, zinc oxide.
A kind of production method of shock-absorbing EVA material is characterized in that: comprise the following steps:
(1) profit is taken: with EVA shock-absorbing glue, zinc oxide mixing 360 ", " rear discharging, be cooled to 120 ℃ then to add whipping agent ADC, bridging agent DCP mixing 60;
(2) thin-pass: it is thick to turn over through the material that step (1) is processed thick secondary to 7 ~ 8mm, then thin 2 ~ 3 times thick to 0.7 ~ 1.0mm, then it is thick to turn over thick secondary to 7 ~ 8mm;
(3) slice: slice thickness 1.3 ~ 1.5mm, the slice temperature is 40 ℃;
(4) sulfuration: at 165 ± 3 ℃, pressure, be 150kg/cm
2Lower processing 1.1 minutes;
(5) compression molding: at 165 ± 3 ℃, pressure, be 70kg/cm
2Lower compression molding.
