The invention mainly relates to thin film processing techniques fields, a kind of fire-retardant film of resistance to boiling is disclosed, is prepared from the following raw materials: polyethylene 46 ~ 48, modified polyvinilidene fluoride 32 ~ 34, polyurethane termoplastic elastomer 15 ~ 17, polyethylene wax 12 ~ 14, polyimides 6 ~ 8, methyl-silicone oil 3 ~ 5, calcium stearate 1.4 ~ 1.6, sodium glutamate 0.5 ~ 0.7；The fire-retardant film of resistance to boiling provided by the invention, intensity is high, and Applicable temperature range is wide, and flame retardant rating reaches V-1 grades, practicability with higher；Polyethylene and modified polyvinilidene fluoride are mixed; and carry out high-temperature vacuum melting; it is sufficiently engaged with polyethylene and modified polyvinilidene fluoride; improve the heat resistance of film; film is able to maintain during boiling and microwave heating to stablize; it is indeformable, increase the practicability of film and the protective effect to food. |
