Description
Technical field
The present invention relates to a kind of processing methods of automobile PU cushion block, belong to automobile interior decoration part processing technique field.
Background technique
Automobile PU cushion block is mounted in the inside gadget on automobile cabin metal plate, plays partial noise and drop in absorption traveling
The effect of Hyporesonance.In use, PU cushion block, which needs to fill, plays damping suction into the cavity of the positions such as such as vehicle body, baffle
The effects of sound, but PU cushion block volume is excessive, it is more narrow to install entrance during the installation process, thus installation process need to expend compared with
The long time, and PU cushion block volume is larger, occupied space is larger during transportation causes transportation cost to increase.
Summary of the invention
The purpose of the present invention is overcoming above-mentioned the deficiencies in the prior art, a kind of processing side of automobile PU cushion block is provided
Method.
The present invention adopts the following technical scheme: a kind of processing method of automobile PU cushion block, includes the following steps:
(1) it will carry out being cut into PU cushion block after PU material foaming, PE vacuum bag, the PE vacuum will be arranged outside the PU cushion block after cutting
Three sides of bag are respectively arranged with edge sealing, and the side of the PE vacuum bag is provided with opening；
(2) using vacuum pumpdown packaging machine to being vacuumized inside PE vacuum bag, vacuum degree 0.5-1.0bar, the pumpdown time
For 25-35s；
(3) opening of PE vacuum bag side is sealed, heat-sealing temperature is 130-140 DEG C, and the heat-sealing time is 1.5-2.5s；
(4) heat-sealing terminates to enter cooling program, and cooling temperature is 10-15 DEG C, and cooling time is 2~3s, vacuum pumpdown packaging machine
Venting solenoid valve running, atmosphere enters the vacuum chamber of vacuum pumpdown packaging machine, and vacuum cover lifts automatically, and taking-up obtains automobile PU
Cushion block finished product.
Further, the density of the PU cushion block is 28-32 kg/m3。
Further, the grammes per square metre of the PE vacuum bag is 65-75g/m2, with a thickness of 0.1-0.15mm.
Further, the length of step (3) the split shed heat-sealing is 145-155mm, and the width for the heat-sealing that is open is 3-
5mm。
The PU cushion block for reducing volume is placed in after installation site in installation process vacuum bag deflate make PU cushion block by
Gradually expansion is until fill full installation site.
Preparation method of the present invention is simple, and step is easily operated, and the automobile PU cushion block volume-diminished being prepared reduces fortune
Defeated cost, it is easy for installation, save the set-up time.
