Take base fabric (1) if, several foamed silica gels and dry rubber substance, be cut into and need specification, in base fabric (1) if upper and lower end face setting
Dry elasticity groove (11) fills track (21) in one side setting " S " type of foamed silica gel；
Step S2: the plasticizing of synthetic leather
Filling track (21) interior applied adhesive on foamed silica gel surface places the upper and lower ends of treated base fabric (1)
Foamed silica gel contacts the one side for filling track (21) with base fabric (1), and rubber is placed in the end face of foamed silica gel, puts completion
Be placed into plasticizing box afterwards and carry out gelation and plasticizing, make base fabric (1) and foamed silica gel layer (2), foamed silica gel layer (2) with
Contact position between rubber layer (3) mutually merges；
Step S3: embossing is cooled and shaped
It after synthetic leather after plasticizing is suppressed under press and is cooled and shaped, band is completed after repairing to corner
The synthetic leather of foamed silica gel base makes.
6. a kind of production method of synthetic leather with foamed silica gel base according to claim 5, it is characterised in that: described
