Environment-friendly thermal insulating decorative plate (PS-3)is a class A non-combustible composite material with a two-layer structure, hard layer and soft layer. The soft layer with longer and softer fibers is made from several natural ores through raw material matching, melting, fiber drawing geometry and needle-weaving processes. The soft layer produced through the new process is resin, residue and dust free, and has no stimulus on human skin like irritation and allergies. The hard layer of high strength consists of multiple inorganic mineral fibers and cured by thermal curing.PS-3 is coated with glass cloth outside of the hard layer and soft layer complex by PSJ type flame-retardant white adhesive. The soft layer is the inner layer which can fit well with steel plates and prevent the condensation of water. It offers good anticorrosion, sound absorption and thermal insulation. The hard layer is the
