A kind of warning tape and preparation method thereof

Abstract

The invention discloses a warning tape and a preparation method thereof, belonging to the technical field of industrial tapes. The warning tape comprises a transparent PVC film, a printing layer, a PVC base material, a bridging agent layer and a glue layer stacked from top to bottom. After adding the printing layer to the PVC base material layer, it is hot-pressed and bonded with the transparent PVC film; and by preparing glue, brushing the printing layer on the top of the PVC base material, and then heat-compressing and bonding the transparent PVC film, and applying it on the bottom of the PVC substrate A layer of bridging agent, followed by a layer of glue, aged, cooled, cut, and rolled into tape rolls to obtain the finished product. The warning tape prepared by the invention has excellent anti-shedding and delamination, high firmness, good aging resistance, good weather resistance, and the effect of preventing edge warping and fading, is reliable and durable, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of industrial tapes, in particular to a warning tape and a preparation method thereof. Background technique [0002] The traditional warning tape is mainly made of a layer of PVC film printed and then coated with glue. The printed layer is directly exposed to the air, which will easily cause the printed layer to oxidize and fall off, discolor and change color, and the whole roll of tape is also easy to run and leak. , the viscosity is not high. [0003] Although some manufacturers have made improvements, a layer of transparent film is pasted on the printed PVC film to make a warning tape, and the transparent PET film is pasted. Delamination is easy to occur, and PVC and PET films are laminated by cold lamination, that is, cold lamination of transparent PET films on the printed PVC film, resulting in tightness and fusion of the two pastes. Poor resistance, easy to appear, delamination, edge warping and othe...

Problems solved by technology

[0002] The traditional warning tape is mainly made of a layer of PVC film printed and then coated with glue. The printed layer is directly exposed to the air, which will easily cause the printed layer to oxidize and fall off, discolor and change color, and the whole roll of tape is also easy to run and leak. , the viscosity is not high

[0003] Although some manufacturers have made improvements, a layer of transparent film is pasted on the printed PVC film to make a warning tape, and the transparent PET film is pasted. Delamination is easy to occur, and PVC and PET films are laminated by cold lamination, that is, cold lamination of transparent PET films on the printed PVC film, resulting in tightness and fusion of the two pastes. Poor resistance, easy to appear, delamination, warping, etc. when the temperature is alternated, causing the warning tape to be easily damaged or peeled off, and the weather resistance is poor

[0004] In addition, the viscosity of the glue used in the current warning tape is not enough, and the fusion with the PVC substrate is not enough, which also causes the tape to fall off easily, or delaminate, or when the warning tape is torn off, the glue delaminates, leaving residue on the adhesive. A lot of glue will affect the appearance of the fitting, and even the glue cannot be cleaned, which will affect the surface of the fitting and even damage it
