Abstract

The process of producing fireproof sofa artificial leather includes the following steps: 1. wet coating polyurethane layer on the base fabric; 2. dry adhering surface polyurethane layer on the semi-finished product; and 3. soaking the fabric in water-base environment friendly fire retardant solution and stoving to obtain the product. In the step 1, the polyurethane resin is polyether or polycarbon type polyurethane resin and has phosphate fire retardant added into the wet slurry; and in the step 2, the polyurethane resin is polycarbon type polyurethane resin with fatty resin, the adhering layer is of aromatic resin and the dry slurry has phosphate fire retardant added. The sofa artificial leather has excellent fireproof function, antiageing performance and antiwear performance.

Description

technical field [0001] The invention relates to a method for manufacturing polyurethane synthetic leather, a method for manufacturing flame-retardant sofa leather with functions such as flame retardancy, aging resistance, weather resistance, and environmental protection. Background technique [0002] Polyurethane synthetic leather (PU synthetic leather) is an imitation leather synthetic leather made by coating polyurethane resin on a cloth substrate and endowing it with various patterns or concave-convex patterns, which is used to replace genuine leather. PU sofa leather is one of the important types of polyurethane synthetic leather. Chinese patent 02135394.8 has introduced a kind of preparation method of microfiber sofa leather, selects superfine fiber non-woven fabric as base cloth, to improve the physical property of sofa leather. Chinese patent 03111848.8 has introduced a kind of bundled microfiber polyurethane sofa leather and its manufacturing method, and the non-wov...
