High brightness flame retardant decorative film

The invention relates to a high brightness flame retardant decorative film, which is prepared by steps of temperature-rising agitation, banburying, filtration, four-roller rolling, primary embossing of mirror surface, non-adhesive pasting process of mirror surface, cooling, reeling and the like by taking PVC (polyvinyl chloride) resin powder and plasticizer as main materials and adding functionalassistants such as a liquid flame retardant, an EVA (ethylene vinyl acetate)-grafted copolymer, soybean oil, a stabilizer and the like. The high brightness flame retardant decorative film of the inveiton has excellent properties such as durable mirror-surface luster, efficient flame retardancy, good strength, size stability and the like.
