Aquosity foaming synthetic leather with contracted pattern provided by the invention, after the leading portion processing, after process back segment embossing and 170 ℃ of high temperature foaming layers were handled through embossing again, each face presented the various lines of embossing plate, and whole structure is good;
Aquosity foaming synthetic leather with contracted pattern provided by the invention, the aqueous foaming resin bed foams through 170 ℃ of high temperature of back segment after the processing, has strong concavo-convex third dimension, and the big-pattern the inside also has the little decorative pattern of flakes that shrinks, the combination that foaming layer, shrinkage layer and embossing are handled, have more third dimension, the effect uniqueness;
Aquosity foaming synthetic leather with contracted pattern provided by the invention, wherein be coated in the aqueous polyurethane layer on the aqueous foaming resin bed, and be coated in modified polyurethane resin on the aqueous polyurethane layer, because three's polarity difference, be used in combination, modified polyurethane can shrink different decorative patterns according to different release liners lines respectively, can produce good contractive effect, the decorative pattern uniqueness has strong visual sense of beauty.
Beneficial effect: the aquosity foaming synthetic leather with contracted pattern provided by the invention is compared with prior art has following advantage:
1, the aquosity foaming synthetic leather with contracted pattern provided by the invention, adopt aqueous foaming resins foamed resin layer, these Foamexes can be the high temperature foamexes of water-based, foamed resin layer has good covering effect, soft, has high temperature resistance preferably after the foaming, resin is volumetric expansion at high temperature, forms the velvet-like coating of one deck, the foaming layer that Foamex forms, the foam hole is even, fine and smooth, have good heat resistance, low temperature contractibility is little, and is fire-retardant, insulation, safety, environmental protection, advantage such as energy-conservation.
2, the aquosity foaming synthetic leather with contracted pattern provided by the invention, the aqueous foaming resin bed foams through 170 ℃ of high temperature of back segment after the processing, has strong concavo-convex third dimension, and the big-pattern the inside also has the little decorative pattern of flakes that shrinks, have more third dimension, the combination that foaming layer, shrinkage layer and embossing are handled, the stereoeffect uniqueness.
3, the aquosity foaming synthetic leather with contracted pattern provided by the invention, wherein be coated in the aqueous polyurethane layer on the aqueous foaming resin bed, and be coated in modified polyurethane resin on the aqueous polyurethane layer, because three's polarity difference, be used in combination, modified polyurethane can shrink different decorative patterns according to different release liners lines respectively, can produce good contractive effect, the decorative pattern uniqueness has strong visual sense of beauty.
4, the aquosity foaming synthetic leather with contracted pattern provided by the invention synthetic leather that is a kind of environment-friendly type shows through experimental study, and bonding firmly between each layer of synthetic leather, coating has advantages such as anti-solvent, cold-resistant, hydrolysis, heat-proof aging; The synthetic leather finished product has good hand feeling, and strong kishke feel is arranged, quality exquisiteness, advantages such as good permeability; Synthetic leather and have resultant effects such as good feel, smooth degree, waterproof, wax sense.
