Flame-retardant butyl pressure sensitive adhesive tape

Abstract

The invention belongs to the technical field of adhesive tape, and particularly discloses flame-retardant butyl pressure sensitive adhesive tape. The adhesive tape comprises an adhesive tape coil composed of a body and an annular drum cavity. A non-work surface of the body is brush-coated with a phosphorus-nitrogen-series flame retardant coating. A protecting device capable of being matched with the adhesive tape coil is arranged outside the adhesive tape coil. The protecting device comprises a protecting cavity and a protecting cover. The corresponding side faces in the length direction of the protecting cavity are provided with slide grooves. A supporting rod is slidingly connected between the slide grooves. The supporting rod is composed of a fixed rod and movable rods. The outer end side faces of the movable rods are connected with a pull plate. By brush-coating the non-work surface of the adhesive tape body with the phosphorus-nitrogen-series flame retardant coating, the coating can have a flame retardant effect on the adhesive tape body; meanwhile, the protecting device has a protecting effect on the adhesive tape body which is installed in the protecting device for use, andtherefore the service life of the adhesive tape is effectively prolonged, and the job content of the adhesive tape is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, in particular to a flame-retardant butyl pressure-sensitive adhesive tape. Background technique [0002] Butyl pressure-sensitive tape is a special type of tape made by applying a special adhesive (pressure-sensitive adhesive) to a strip-shaped substrate. It consists of pressure-sensitive adhesive, base material, primer, back treatment agent, etc. Pressure sensitive adhesive is the most important component of pressure sensitive tape. Its role is to give the tape its pressure-sensitive adhesive properties. The main materials used as substrates are fabrics, plastic films, paper, etc. The primer is to increase the bond strength between the pressure sensitive adhesive and the substrate. When using, apply light pressure to make the adhesive tape adhere to the surface of the adherend.

AI Technical Summary

Problems solved by technology

[0003] Because butyl pressure-sensitive tape is usually an organic polymer material containing rubber, mineral oil and tackifying resin, rubber, mineral oil and tackifying resin are all flammable substances with low ignition point and low oxygen combustion. Low index and other shortcomings, so it is easy to have safety hazards due to flammability during use, and the pressure-sensitive tape is often exposed in the air after use. At this time, the unprotected tape is not only easy to burn after encountering an open flame, but also It will be damaged under external force or humid environment, which will affect the service life and quality of butyl pressure sensitive tape
