Abstract

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.

Description

technical field [0001] The invention relates to the application field of optical films, in particular to a preparation process of a flame-retardant reflective warning tape. Background technique [0002] At present, most of the flame-retardant warning tapes on the market adopt the preparation process of 3M in the United States, such as the Chinese patent "Retroreflective Products and Its Manufacturing Method" (Patent No. ZL95193042.7). The preparation process is: a. into glass beads, the film is called a plant film; b. a part of the metal reflective layer is coated on the glass beads of the bead-planted film; c. a flame retardant is coated on the bead-planted film coated with a part of the metal reflective layer Put the compound glue in the drying tunnel to dry the solvent; d. After hot ironing and compounding with flame-retardant cotton cloth, blended fabric or aramid cloth, wind up. After the compound glue is completely cured, peel off the PE / PET composite film and wind up....
