6) cooling and standings: the sheet material vulcanizated is placed and is cooled down.
Wherein, in step 2), the water temperature of mixer is controlled at 40~70 DEG C hereinafter, 0.7~0.9MPa of compressed air pressure,
Controlling material temperature is 105~115 DEG C.
In step 3), when mill, 80~90 DEG C of preceding roll temperature, mends refining by 70~80 DEG C, 0.3~0.7mm of roll spacing of rear roll temperature
3~5 times.
In step 5), when sulfur foam is handled, 0.7~0.75MPa of steam pressure, mould specification 600mm*1200mm*
7mm, vulcanization time are 10~12 minutes.
The utility model has the advantages that
The present invention is using dual-tert-butyl dicumyl peroxide and double 25 preparations without acetophenone EVA foamed material, substitution
Crosslink agent DCP originally, technique are examined using the technique of tradition EVA foaming by liquid chromatography mass instrument/gas chromatography mass spectrometer
It surveys, does not contain acetophenone.Dual-tert-butyl dicumyl peroxide is main crosslinking agent, but dual-tert-butyl diisopropyl peroxide
Benzene crosslinking rate is slow, and cross-linked surface density is poor, and double 25 be assistant crosslinking agent, and two kinds of crosslinking agents are used cooperatively, and is made by collaboration
With the degree of cross linking of product can be improved, mechanical performance will not be reduced.
