Abstract
The present application provides a flame-retardant insulating film comprising a polypropylene resin matrix and a halogen-free intumescent flame retardant. The polypropylene resin matrix accounts for 47%-60% of the weight of the flame-retardant insulating film and comprises a high melt strength polypropylene, which accounts for 35%-100% of the weight of the polypropylene resin matrix. The halogen-free intumescent flame retardant accounts for 40%-60% of the weight of the flame-retardant insulating film.
Claims13
A flame-retardant insulating film, wherein the flame-retardant insulating film comprises:
- a polypropylene resin matrix, which weight accounts for 47%-60% of the weight of the flame-retardant insulating film, the polypropylene resin matrix comprising a high melt strength polypropylene, which weight accounts for 35%-100% of the weight of the polypropylene resin matrix;
- and
- a halogen-free intumescent flame retardant, which weight accounts for 40%-60% of the weight of the flame-retardant insulating film.
A formulation of a flame-retardant insulating material, wherein the formulation comprises:
- a polypropylene resin matrix, which weight accounts for 47%-60% of the weight of the flame-retardant insulating film, the polypropylene resin matrix comprising a high melt strength polypropylene, which weight accounts for 35%-100% of the weight of the polypropylene resin matrix;
- and
- a halogen-free intumescent flame retardant, which weight accounts for 40%-60% of the weight of the flame-retardant insulating film.
