When fixed thick operation, due to the polymer base material molten liquid cast sheet 140 and self-adhesion macromolecule butyl glue in coiled material cast sheet 100
There is certain bonding strength between cast sheet 130, it will not be molten to polymer base material in upper roller 310, central roll 320 and lower roll 330
Melt liquid cast sheet 140 and when self-adhesion macromolecule butyl rubber liquid cast sheet 130 is rolled separates, to prevent the production of defective products
It is raw.The effect that press polish fixed thick operation is carried out when 100 temperature of coiled material cast sheet is between 160 degrees Celsius~170 degrees Celsius is best,
If coiled material cast sheet 100 carries out press polish fixed thick operation in the state of being higher than 170 degrees Celsius, it is easy to happen above-mentioned polymer-based
Material molten liquid cast sheet 140 and the separated phenomenon of self-adhesion macromolecule butyl rubber liquid cast sheet 130, cause press polish to fail, and generate not
Non-defective unit；It is operated if coiled material cast sheet 100 on the contrary carries out press polish fixed thickness in the state of being lower than 160 degrees Celsius, since coiled material is cast
100 undercooling of piece, self-adhesion macromolecule butyl rubber liquid cast sheet 130 and polymer base material molten liquid in coiled material cast sheet 100
Cast sheet 140 has had been provided with certain hardness, or even is soon formed, when carrying out press polish using three-roller calendar 300, upper roller
310, central roll 320 and lower roll 330 have been difficult coiled material cast sheet 100 to change the thickness of coiled material cast sheet 100, are difficult leveling volume
The gauffer on 100 surface of material cast sheet, cause exempt from apply glue-type waterproof roll it is in uneven thickness.
It should be noted that please referring to Fig. 1 and Fig. 2, in order to improve the fixed thick effect of press polish, need to upper roller 310, central roll
320 and lower roll 330 heated so that upper roller 310, central roll 320 and lower roll 330 itself have certain temperature, adjust coiled material
The temperature of polymer base material molten liquid cast sheet 140 in cast sheet 100 and the drop of self-adhesion macromolecule butyl rubber liquid cast sheet 130
Warm rate, when coiled material cast sheet 100 being avoided to carry out step S140 operation, because cooling is too fast to lead to the interior of coiled material cast sheet 100
Phenomena such as stress is excessive, and warpage occurs.Further, in step s 110, self-adhesion macromolecule butyl glue and polymer base material
The initial temperature of molten liquid is different, and its material is also different, when leading to carry out step S140 in this way, coiled material curtain coating
The temperature of polymer base material molten liquid cast sheet 140 on piece 100 and the temperature of self-adhesion macromolecule butyl rubber liquid cast sheet 130
It has differences, in order to enable coiled material cast sheet 100 gradually to cool down, prevents polymer base material molten liquid cast sheet 140
It the problem of warpage caused by the rate of temperature fall of temperature and self-adhesion macromolecule butyl rubber liquid cast sheet 130 differs greatly, needs to guarantee
Temperature in press polish on upper roller 310, central roll 320 and lower roll 330 is respectively different, wherein since polymer base material molten liquid is initial
The temperature setting of the higher central roll 320 of temperature is 80 degrees Celsius~100 degrees Celsius, since in the fixed thick operation of press polish, upper roller 310 is first
It is contacted with coiled material cast sheet 100, therefore the temperature of upper roller 310 is higher than the temperature of lower roll 330, the temperature setting by upper roller 310 is
60 degrees Celsius~70 degrees Celsius, the temperature setting of lower roll 330 is 50 degrees Celsius~60 degrees Celsius, and the temperature of central roll 320 compares upper roller
310 and lower roll 330 it is high, in press polish, polymer base material molten liquid 140 cooling velocities of cast sheet can be prevented too fast, lead to high score
The shrinking percentage of subbase material molten liquid cast sheet 140 is greater than self-adhesion macromolecule butyl rubber liquid cast sheet 130, makes coiled material cast sheet 100
Warpage occurs；The temperature of upper roller 310 is higher than the temperature of lower roll 330, can prevent self-adhesion macromolecule butyl rubber liquid cast sheet 130
Cooling rate is too fast, and the shrinking percentage of self-adhesion macromolecule butyl rubber liquid cast sheet 130 is caused to be cast greater than polymer base material molten liquid
Piece 140 makes coiled material cast sheet 100 that warpage occur.
Fig. 1 and Fig. 2 is please referred to, if the temperature on upper roller 310, central roll 320 and lower roll 330 is greater than above-mentioned preset value, is held
Coiled material cast sheet 100 roll release difficulty is easily led to, the fixed thick effect of press polish is influenced, generates Cross slat on 100 surface of coiled material cast sheet
Line；If the temperature on upper roller 310, central roll 320 and lower roll 330 is less than above-mentioned preset value, coiled material stream when the fixed thickness of press polish operates is carried out
Prolong the more difficult surface for being close to roller of piece 100, the surface obtained for exempting to apply glue-type waterproof roll is caused to generate spot, tarnish.
