Polyurethane synthetic leather for silky suede sofa furniture and preparation method of polyurethane synthetic leather

Abstract

The invention discloses polyurethane synthetic leather for silky suede sofa furniture and a preparation method of the polyurethane synthetic leather. The polyurethane synthetic leather sequentially comprises a polyurethane surface layer, a middle layer, a bonding layer and a base cloth layer from top to bottom, wherein the polyurethane surface layer is prepared by coating the surface of velvet release paper with polyurethane slurry and then drying, and the polyurethane slurry is prepared from the following components in parts by weight: 100 parts of polycarbon resin, 70-90 parts of a solvent,5-6 parts of organic silicone oil, 4-5 parts of a melamine curing agent, 0.15-0.2 part of an accelerant and 15-18 parts of color paste. The polyurethane synthetic leather produced by the method is tender and smooth in surface and soft in hand feeling, and has a genuine leather suede effect; The polyurethane synthetic leather is produced through a full-dry method, one-time forming is achieved, production is simple and efficient, and a preparation period is short. In addition, the polyurethane synthetic leather for silky suede sofa furniture produced by the invention is lower in cost compared with genuine leather, and is ecological and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of polyurethane synthetic leather manufacture, in particular to a polyurethane synthetic leather for silky suede sofa furniture and a preparation method thereof.

Problems solved by technology

Although natural leather suede products have the advantages of delicate and comfortable leather surface, soft and plump hand feeling, and good hygienic performance, they are expensive, the production environment is poor, and they do not meet the national environmental protection requirements. Moreover, raw materials are increasingly scarce and manufacturing costs are increasing; Although the physical and mechanical properties of velvet-like polyurethane synthetic leather are superior to natural leather, the surface of the finished product has poor touch, the leather surface is rough, not silky and tender enough, and the texture is poor, and the hand feels stiff and not full enough
