Description

Printing-free warning adhesive tape

Technical Field

The utility model relates to an adhesive technical field especially relates to a printing-free warning sticky tape.

Background

The warning tape has the advantages of water resistance, moisture resistance, weather resistance, corrosion resistance, static electricity resistance and the like, and is suitable for the corrosion protection of underground pipelines such as air pipes, water pipes, oil pipelines and the like. The twill printing adhesive tape can be used for warning signs in areas such as ground, columns, buildings, traffic and the like. When the warning lamp is used for warning, red indicates the prohibition and prevention, the red and white alternate stripes indicate the prohibition of people from entering dangerous environments, the yellow and black alternate stripes indicate the attention of people, and the green and white alternate stripes indicate the more striking prompt of people.

Most of the warning tapes commonly used in the market at present are PVC printing forming coating solvent type acrylic glue, a large amount of plasticizer is used in the PVC generation process, the plasticizer gradually migrates out of a base material in the subsequent use process and goes to the environment, and the volatilization of a large amount of solvent and the generation of harmful substances exist in the production and manufacturing process of the solvent type acrylic glue. The PVC warning tape has the advantages that the damage to the environment is extremely large, the damage to the adhesive tape can be generated to the environment in the production, manufacturing and product aging processes, in addition, the PVC warning tape is uneven in tear opening and needs to be cut by a knife, and the strength is low. The other PET film-coated warning tape cannot be torn off by hands, so that the use experience is relatively influenced, and the residual adhesive exists after long-term use.

Therefore, in order to overcome the defects of the prior art, a completely new adhesive tape needs to be developed.
