Embodiment 1
[0020] The invention provides a phosphorus-free and halogen-free flame-retardant polyester sheet, the composition of the sheet substrate is as follows (percentage by weight):
[0021] Polyethylene terephthalate accounts for 78%, polybutylene terephthalate accounts for 18%, glass fiber accounts for 1%, antioxidant 1010 accounts for 1%, ethylene-vinyl acetate copolymer accounts for 0.5%, octadecane Dimethyl quaternary ammonium nitrate accounted for 0.9%, benzophenone accounted for 0.6%.
[0022] The surface of the polyester sheet substrate is coated with a coating containing a phosphorus-free and halogen-free flame retardant, and the coating contains 15% (by weight) of a phosphorus-free and halogen-free flame retardant, 83% (by weight) of And 2% (weight percent) of MF dispersant. Among them, the phosphorus-free and halogen-free flame retardant is composed of 40% (weight percent) sodium polyacrylate and 60% (weight percent) polypropylene carbonate. Sodium polyacrylate has a netw...
