Between groove and banking stop, cutter spacing is applied between the second hopper and banking stop;Walking speed of the base fabric on delivery platform is 8m/min.
Compared with prior art, the present invention devises a kind of method and system of processing for improving synthetic leather peel strength;First
By scraper, the clear material of one layer of 0.2mm~0.8mm thickness is scraped in scrim surfaces, i.e., the pure poly- ammonia of last layer is scraped in base fabric upper surface
The compound of ester and DMF;Then again by applying cutter painting last layer slurry, i.e., a strata urethane is coated in clear bed of material upper surface and is filled out
The compound of charge;Transition bonding is carried out using pure polyurethane, so that the bonding strength of slurry is improved, without glue layer
In the case of, the bonding strength between top layer and nexine is improved, the peel strength of finished product is improved, removed from office compared to conventional synthesis
The peel strength of 0.5~0.7 kg per cm, peel strength of the invention can be improved to 0.9~1.2 kg per cm, no
Peel strength can be only improved, is increased the service life, additionally it is possible to avoids formaldehyde unhealthful, safety in utilization is good.In addition, this hair
It is bright also by enter the solid 8min~12min of water-setting, 25 DEG C~30 DEG C washings remove DMF and 130 DEG C~150 DEG C drying 5min~
10min, to solidify the clear bed of material and pulp layer and remove DMF therein, forms constitutionally stable finished product.Therefore, the present invention not only
