Technical Field

The invention relates to a medical adhesive tape back treating agent, a processing method thereof and a back treatment production process using the medical adhesive tape back treating agent, belonging to the field of medical adhesive tape back treating agents.

Background

The medical adhesive tape is a rolled medical product as the name suggests. The adhesive tape product needs to be uncoiled in the using process and is cut off after reaching the required length, and the key point is that the adhesive tape has good uncoiling force so as to be convenient for medical staff to use. The unwinding force is realized by carrying out back treatment on the adhesive tape, the conventional back treatment production process needs to coat a layer of slurry on the surface of the base material firstly to ensure that the pores on the surface of the base material are filled with the slurry, a layer of release agent is coated on the surface of the slurry through treatment equipment after drying and rolling, and then drying and rolling are carried out, and because the usage amount of the release agent is very small, the release agent is difficult to uniformly disperse in one-time coating, and secondary coating of the release agent can be caused. This results in high energy consumption for the back treatment, and the amount of the treating agent used is difficult to control, and improper use results in a small or large unwinding force, with the result that the tape cannot be opened and used or the tape cannot be wound. The base material supplier generally does not have the back processing capability, and needs to find a third party manufacturer to perform the back processing of the base material, thereby increasing the transportation cost, causing the phase change of the production time to be lengthened, and having great influence on adhesive tape production enterprises. The invention can directly purchase the original base material, and after the adhesive is coated, the adverse factors can be avoided only by one-time back treatment, so that the manufactured adhesive tape product has excellent unwinding performance, the adhesive force of the adhesive tape is not reduced, and the production cost is greatly saved.
