(57) [Summary] [Problem] A non-halogen flame-retardant polyolefin that is excellent in processability and physical properties as a material, is a resin material for leather provided with flame retardancy, and is easy to recycle even if it becomes unnecessary and is discarded. Offer leather. SOLUTION: The synthetic resin leather has a three-layer structure and is integrally formed by extrusion molding, calendering processing, roll processing, etc., and the material is composed of a skin layer (A) a mixed composition of a polyolefin and a flame-retardant layer. (B) a mixture composition of a polyolefin and an inorganic flame retardant, a base fabric (C) a woven fabric such as polyester and rayon, a sheet such as polypropylene or a foamed sheet, and a flame retardant layer (B) as an intermediate material having three layers. Halogen-free flame-retardant polyolefin leather, characterized in that the whole is flame-retardant. |
