Abstract
The invention discloses a hard ethylene vinyl acetate (EVA) shoe sole material and a production method thereof. The hard EVA shoe sole material is composed of EVA 7350, stearic acid and bridging agent dicumyl peroxide (DCP). The hard EVA shoe sole material is high in hardness, good in work performance and capable of meeting the requirement of high hardness, and the hardness of the material can reach 90+/-3 (HC).
Description
Technical field
The present invention relates to a kind of EVA material for sole of shoe and working method thereof.
Background technology
There is shortcoming in existing EVA material for sole of shoe at aspects such as hardness performances, need further to improve.
Summary of the invention
The object of the present invention is to provide the hard EVA material for sole of shoe and the working method thereof of a kind of hardness height, favorable working performance.
Technical solution of the present invention is:
A kind of hard EVA material for sole of shoe, it is characterized in that: the raw material by following weight part is formed:
500 parts of EVA7350
4 ~ 6 parts of Triple Pressed Stearic Acid
4 ~ 6 parts of bridging agent DCP.
A kind of working method of hard EVA material for sole of shoe is characterized in that: comprise the following steps: successively
(1) profit is taken: " the back discharging is cooled to 120 ℃ with mixing 360 seconds of EVA7350, Triple Pressed Stearic Acid, to add bridging agent DCP mixing 60 again;
(2) thin logical: it is thick to turn over thick secondary to 7 ~ 8mm through the material that step (1) is handled, thin then 2 ~ 3 times thick to 0.7 ~ 1.0mm, it is thick to turn over thick secondary to 7 ~ 8mm again;
(3) printing: will carry out ink printing through glue of material brush of above-mentioned processing, and brush glue behind the ink printing again a time;
(4) severing: divide size to carry out severing;
(5) mold pressing: in temperature is mold pressing under 162 ~ 168 ℃, pressure 70kg/cm2, and be 8 ~ 9 minutes heat-up time, 8 ~ 9 minutes cooling times;
(6) arrangement: carry out deburring, trimming.
Hardness of the present invention is high, reaches 90 ± 3 (HC), and favorable working performance can satisfy the needs of high firmness.
Below in conjunction with embodiment the present invention is described further.
