Problems solved by technology

In the prior art, there are many technical difficulties in embossing artificial 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

[0014] Such as figure 1 Shown, a kind of water-based PU artificial leather with stereoscopic pattern, it comprises base cloth layer 1, be coated on the polyurethane PU layer 2 on described base cloth layer 1, be coated on the water-based polyurethane bonding on polyurethane PU layer 2 Layer 3, the water-based PU resin layer 4 coated on the water-based polyurethane adhesive layer 3, the silicone-modified polyurethane 5 coated on the water-based PU resin layer 4, the crystal feeling coated on the silicone-modified polyurethane 5 Resin 6 and high-solid glossy resin 7 coated on crystal resin 6 .

[0015] In the artificial leather of the present invention, the water-based PU resin layer has a strong concave-convex crystal three-dimensional effect after being treated with PU at a high temperature of 190° C., and the combination of the PU layer, shrinkage layer and embossing treatment has a more three-dimensional effect and a unique effect. Among them, the high-solid bright surf...

Abstract

The invention discloses a water-based PU artificial leather with a stereoscopic impression pattern. The artificial leather comprises a base cloth layer, a polyurethane PU layer coated on the base cloth layer, an aqueous polyurethane adhesive layer coated on the polyurethane PU layer, an aqueous PU resin layer coated on the aqueous polyurethane adhesive layer, modified polyurethane resin coated on the aqueous PU resin layer, crystal resin coated on the modified polyurethane resin and high solid polished resin coated on the crystal resin. The aqueous PU resin layer of the artificial leather provided by the invention is subjected to post high temperature PU treatment at 190 DEG C to gain strong concavo-convex crystal stereoscopic impression, better stereoscopic impression and unique effect. The high solid polished resin is a PU artificial leather post treatment resin with high solid content, and has characteristics of high gloss and high brightness; and the high solid polished resin cooperates with the crystal resin mutually to obtain synthesized leather with advantages of smoothness, scratch resistance and strong sense of cashmere.

Description

technical field [0001] The invention relates to a PU artificial leather, in particular to an artificial leather with three-dimensional pattern and strong three-dimensional visual effect. Background technique [0002] At present, artificial leather products have gradually become a popular trend in the future, and artificial 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 artificial leather meet people's needs for leather surface...
