Junk box for bar hot-peeling technology

The invention discloses a junk box for a bar hot-peeling technology. A box body material of the junk box is prepared from raw materials in parts by weight as follows: 30-40 parts of polytetrafluoroethylene, 10-20 parts of polyimide, 10-20 parts of polyphenylene sulfide, 8-10 parts of silicone rubber, 8-10 parts of organic montmorillonite, 10-12 parts of graphite, 5-6 parts of silica, 2-3 parts of polymethyl methacrylate, 4-5 parts of boron nitride, 2-3 parts of silicon nitride, 3.5-4.5 parts of hydroxyl silicone oil, 1.5-2 parts of methylcellulose, 1-2 parts of an impact modifier and 0.5-0.8 parts of a coupling agent. The junk box for the bar hot-peeling technology has excellent high-temperature resistance, flame retardance, corrosion resistance and the like and can be used for collecting waste in the bar hot-peeling technology.
