Problems solved by technology

In the prior art, there are many technical difficulties in embossing synthetic leather. The visual effect of the pattern obtained by embossing is poor, and the embossing process requires a lot of equipment and high cost. At the same time, the retention time of the pattern obtained by printing is relatively short. , easy to fade, can not meet people's requirements for high standards

Embodiment 1

[0022] Such as figure 1 Shown, a kind of water-based foamed synthetic leather with embossed shrink pattern, it comprises base cloth layer 1, the polyurethane foam layer 2 that is coated on described base cloth layer 1, is coated on polyurethane foam layer 2 The water-based polyurethane adhesive layer 3, the water-based foamed resin layer 4 coated on the water-based polyurethane adhesive layer 3, and the silicone-modified polyurethane 5 coated on the water-based foamed resin layer 4.

[0023] The above synthetic leather, after the water-based foaming resin layer is foamed at a high temperature of 170 ℃ in the later stage, has a strong three-dimensional effect of bumps and convexes. The combination of foam layer, shrinkage layer and embossing treatment has a more three-dimensional effect and a unique effect. Among them, the silicone-modified polyurethane resin coated on the water-based foaming resin layer, due to the different polarity of the two, used in combination, the modifi...

Embodiment 2

[0025] Such as figure 2 Shown, a kind of water-based foamed synthetic leather with embossed shrink pattern, it comprises base cloth layer 1, the polyurethane foam layer 2 that is coated on described base cloth layer 1, is coated on polyurethane foam layer 2 The water-based polyurethane adhesive layer 3, the water-based foamed resin layer 4 coated on the water-based polyurethane adhesive layer 3, and the acrylic modified polyurethane 5 coated on the water-based foamed resin layer 4.

Embodiment 3

[0027] Such as image 3 Shown, a kind of water-based foamed synthetic leather with embossed shrink pattern, it comprises base cloth layer 1, the polyurethane foam layer 2 that is coated on described base cloth layer 1, is coated on polyurethane foam layer 2 The water-based polyurethane adhesive layer 3, the water-based foamed resin layer 4 coated on the water-based polyurethane adhesive layer 3, and the water-based modified polyurethane 5 coated on the water-based foamed resin layer 4. The above is only a preferred embodiment of the present invention, it should be pointed out that, for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.

Abstract

The invention discloses an aquosity foaming synthetic leather with knurling shrunken patterns, comprising a base fabric layer (1), a polyurethane foaming layer (2) coated on the base fabric layer (1), an aquosity polyurethane bonding layer (3) coated on the polyurethane foaming layer (2), an aquosity foaming resin layer (4) coated on the aquosity polyurethane bonding layer (3) and a modified polyurethane resin layer (5) coated on the aquosity foaming resin layer (4). In the synthetic leather provided, the aquosity foaming resin layer has strong concave-convex three-dimensional sense after rear-segment foaming treatment at a high temperature of 170 DEG C; the combination of the foaming layer, the shrinkage layer and the knurling processing have unique three-dimensional sense effect; besides, the modified polyurethane can shrink to form different patterns according to different release paper patterns as a result of the polarity difference between the modified polyurethane resin coated on the aquosity foaming resin layer and the aquosity foaming resin layer combined for use, thereby the invention has favorable shrinkage effect, unique patterns and strong visual aesthetics.

Description

technical field [0001] The invention relates to a PU synthetic leather, in particular to a synthetic leather with a contraction pattern and a strong three-dimensional visual effect. Background technique [0002] At present, synthetic leather products have gradually become a popular trend in the future, and synthetic leather has been widely used in the production of luggage, clothing, footwear and other products. The base fabric of PU leather is a canvas PU material with good tensile strength. In addition to being coated on the top of the base fabric, the base fabric can also be included in the middle, so that the existence of the base fabric cannot be seen from the outside. PU leather has physical properties. Good, resistance to twists and turns, good softness, high tensile strength, and breathability, so PU leather is widely used in the fabric of footwear or the weight-bearing parts of bags. In order to make synthetic leather meet people's needs for leather surface pattern...
