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

[0017] like figure 1 Shown, a kind of synthetic leather with shrink pattern, it comprises base fabric layer 1, the polyurethane foam layer 2 that is coated on described base fabric layer, the polyurethane bonding layer 3 that is coated on polyurethane foam layer 2 , the polyurethane cracking resin 4 coated on the polyurethane bonding layer 3 and the silicone modified polyurethane 5 coated on the polyurethane cracking resin 4 .

[0018] The above synthetic leather, in which the polyurethane cracking resin coated on the polyurethane bonding layer has a special bright surface cracking effect, and a layer of silicone modified polyurethane is coated on the cracking resin. The combination of the two can It produces good shrinkage effect and has a unique pattern, and the cracked resin and silicone modified polyurethane can shrink to produce different patterns according to different release paper lines, which has a strong visual aesthetic feeling.

Embodiment 2

[0020] like figure 2 Shown, a kind of synthetic leather with shrink pattern, it comprises base fabric layer 1, the polyurethane foam layer 2 that is coated on described base fabric layer, the polyurethane bonding layer 3 that is coated on polyurethane foam layer 2 , the polyurethane cracking resin 4 coated on the polyurethane bonding layer 3 and the acrylic modified polyurethane 5 coated on the polyurethane cracking resin 4 .

Embodiment 3

[0022] like image 3 Shown, a kind of synthetic leather with shrink pattern, it comprises base fabric layer 1, the polyurethane foam layer 2 that is coated on described base fabric layer, the polyurethane bonding layer 3 that is coated on polyurethane foam layer 2 , the polyurethane cracking resin 4 coated on the polyurethane bonding layer 3 and the epoxy-modified polyurethane 5 coated on the polyurethane cracking resin 4 .

[0023] The invention provides a synthetic leather with a shrinkage pattern, which has excellent hand feeling and comprehensive performance, has a special shiny surface cracking effect and can produce a good shrinkage effect, has a unique pattern, and is modified by cracking resin and organic silicon. Polyurethane can shrink into different patterns according to different lines of release paper, which has a strong visual aesthetic feeling.

Abstract

The invention discloses synthetic leather with contracted patterns, which comprises a substrate cloth layer, a polyurethane foaming layer (2) coated on the substrate close layer (1), a polyurethane adhesive layer (3) coated on the polyurethane foaming layer (2), polyurethane cracking resin (4) coated on the polyurethane adhesive layer (3) and modified polyurethane (5) coated on the polyurethane cracking resin (4). In the synthetic leather, the polyurethane cracking resin coated on the polyurethane adhesive layer has special polished cracking effect, the modified polyurethane is coated on the cracking resin, the modified polyurethane and the cracking resin are combined to play a synergistic function and can generate fine contraction effect with unique patterns, and the cracking resin and the modified polyurethane can be contracted to form different patterns according to different texture of release paper, thereby having strong visual aesthetics.

Description

technical field [0001] The invention relates to a PU synthetic leather, in particular to a synthetic leather with shrinkage pattern and strong 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 patterns and patterns, it is of...
