PURPOSE: A recycling method of adhesive film for safety glass manufacture is provided to be applied in various fields by recycling the adhesive film scrap processed as the waste effectively, and to be used as the waterproof sheet. CONSTITUTION: The recycling method of adhesive film for safety glass manufacture includes the process as follows. The scrap crushed material shatters the adhesive film scrap for manufacture. The crushed scrap material mixes the polymer, filler, additive, the wood dust, resin, pigment, plasticizer and lubricant and passes the mixture through the extruder. The impurities are removed by filtering with filtering net. PVB composite sheet, which recycled the adhesive film for safety glass manufacture, is manufactured by cutting the composite material after manufacturing the composite material. The double composite waterproof layer protecting material sheet is manufactured by attaching the composite sheet(10) in the protective sheet for construction and engineering works.
