Problems solved by technology
Therefore, synthetic leather is mainly composed of polyurethane resin layer and base cloth layer. The texture of the synthetic leather depends on the texture of the release paper, and the three-dimensional effect of the formed leather surface is poor.
In order to make synthetic leather meet people's higher pursuit of leather patterns and patterns, it is necessary to process synthetic leather with embossing technology to make synthetic leather have concave-convex three-dimensional patterns, but the concave-convex patterns formed by this embossing process are not enough. Naturally, the resulting synthetic leather is not aesthetically pleasing

Embodiment Construction
[0011] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0012] Such as figure 1 As shown, the synthetic leather according to this embodiment comprises a cloth base cloth 1, a polyurethane cell layer 2 covered on the cloth base cloth 1, a silicone modified polyurethane resin layer covered on the polyurethane cell layer 2 3. The acrylic resin layer 4 covering the silicone-modified polyurethane resin layer 3 .
[0013] The production process of synthetic leather of the present invention is:
[0014] First, scrape the acrylic resin onto the mirror release paper to form the acrylic resin layer;
[0015] Then, the organosilicon-modified polyurethane resin added with excess hydroxyl organosilicon is coated and scraped on the acrylic resin layer to form the organosilicon-modified polyurethane resin layer;
[0016] Then apply the release paper on the wet-laid bass (obtained by bonding the silicone-modified...

The invention discloses synthetic leather having solid bubble-shaped figures, which comprises a cloth substrate, a polyurethane abscess layer covered on the cloth substrate, an organic silicon modified polyurethane resin layer covered on the polyurethane abscess layer and an acrylic resin layer covered on the organic silicon modified polyurethane resin layer. Due to different polarities of the acrylic resin layer and the organic silicon modified polyurethane resin layer, after being scraped onto release paper, the resin can contract so as to form natural, random and irregular solid bubble-shaped figures on the synthetic leather. The synthetic leather has strong concave-convex third dimension.
Description
technical field [0001] The invention relates to a synthetic leather, in particular to a synthetic leather with a three-dimensional bubble pattern. Background technique [0002] In the prior art, the dry production process generally uses release paper as a carrier, PU resin slurry is coated and scraped on it, and then enters an oven, heated and dried to remove the solvent in the resin to form a PU polyurethane film, and then the bass or Other substrates and the PU polyurethane surface layer are bonded together through an adhesive layer to form a synthetic leather product, and after cooling, the release paper is finally separated from the synthetic leather to form a finished product. Therefore, the synthetic leather is mainly composed of a polyurethane resin layer and a base cloth layer. The texture of the synthetic leather depends on the texture of the release paper, and the three-dimensional effect of the formed leather surface is relatively poor. In order to make synthetic...
