(1) the coated on one side toluene that will be bonded in foamed cotton layer with layers of two-sided, is then allowed to stand 30min-60min, dries in the air naturally
It is dry；
(2) is in laminated coating toluene and the silica gel treatment mixed liquor again of the foam for being coated with toluene, and in mixed liquor
The weight ratio of silica gel treatment and toluene is 2.5: 1-4.5: 1, then stands 30min-60min, naturally dry again；
(3) is laminated compound by the one side of layers of two-sided and the foam that is coated with toluene and silica gel treatment mixed liquor, double
The another side of face glue-line has release layer；
(4) further presses the compound good material comprising release layer, layers of two-sided, foamed cotton layer by hot-pressing roller, heat
The temperature of pressure roller controls between 70 DEG C -100 DEG C, and composite material is by the speed control of hot-pressing roller at 1-3 ms/min.
Finally suitable size, the foam adhesive tape of length are cut into as needed.
The foam is 4305 type foams or EVA foams.
The silica gel treatment is the silica gel treatment that the commercially available mark name of an article is 94 silane coupling agents.
The foam adhesive tape made of the method for the present invention, the bonding of foamed cotton layer and layers of two-sided is very close, hand tear test
Even if showing that foam and double-sided adhesive layer can not also be removed by having torn foam, show that foamed cotton layer can be answered effectively with layers of two-sided
It is integrated, can ensure that the bond properties of product and the service life of product；In addition, can preferably be controlled using the method for the present invention
Product cost.

The mode even spread toluene of person's spraying, slowly conveys or stands, naturally dry 30 minutes；Then again using blade coating or spray
The mode of painting is coated with silica gel treatment and toluene mixture liquid on foamed cotton layer, is slowly delivered to multi-procedure or standing, natural
It dries 60 minutes；
Then one side stripping exposing glue surface, another side are compounded with to the glue surface of the layers of two-sided of the thickness about 1mm of release layer
Be coated with silica gel treatment and toluene mixture liquid dry after to cross roller compound on foam surface；Hot-pressing roller is delivered to again to be pressed
Close, the control of the temperature of hot-pressing roller at 70 DEG C, hot-pressing roller by being spaced about 2mm；By the speed control of hot-pressing roller at 2m/ points
Clock；
Finally compound good product is cut as needed.
Embodiment 2
Prepare toluene portion as coating liquid for the first time, prepares silica gel treatment with toluene mixture liquid portion as second
Secondary coating liquid, silica gel treatment use the commercially available mark name of an article produced by 3M China Co., Ltd. for the silicon of " 94 silane coupling agent "
