The invention discloses a preparation technique for a
flame-retardant reflective warning tape. The preparation technique for the
flame-retardant reflective warning tape includes steps that (1) preparing gray cloth, to be specific,
coating a fluorescent
coating on a
flame-retardant cloth base, and
cutting into gray cloth with different widths for latter use; (2) implanting glass micro-beads; (3) preparing a focusing layer; (4) preparing a
metal coating; (5) preparing a flame-retardant composite
adhesive layer and a flame-retardant
hot melt adhesive layer, to be specific, coating the flame-retardant composite
adhesive layer on the
metal coating, after
drying the
solvent, compounding with the flame-retardant
hot melt adhesive film through hot ironing, after the composite adhesive is solidified completely,
cutting into flame-retardant composite
heat transfer films with different widths; (6) hot ironing to compound, to be specific, compounding the gray cloth of the step (1) with the flame-retardant composite
heat transfer films of the step (5) through hot ironing, and peeling off a PE / PET
composite film. The preparation technique for the flame-retardant reflective warning tape has advantages that the preparation technique consumes a little of raw materials, and the manufacturing cost is low; the edge of the composite
reflective layer is clear and textured; an intermediate tape plays a role of reflecting light, and tapes at two sides play a role of fluorescent warning.
