Description

Novel waterproof breathable adhesive tape Technical Field The utility model relates to the technical field of breathable adhesive tapes, in particular to a novel waterproof breathable adhesive tape. Background The breathable adhesive tape is a tape-shaped or sheet-shaped adhesive material, is divided into elastic or inelastic, is not in direct contact with a wound surface, has an intact skin adhesive part, and can promote the rapid healing of a wound, wherein the mud is in contact with the wound, and plays a role in helping the healing of the wound. The utility model discloses a ventilative sticky note that water-proof effects is good of current publication No. CN218607059U, specifically disclose including the non-woven fabrics to and set up the pressure sensitive adhesive layer in the non-woven fabrics upper end, set up the release paper in pressure sensitive adhesive layer upper end, from the lower extreme external surface fixedly connected with prevention of seepage circle of release paper, the upper end surface of non-woven fabrics is provided with the PU membrane, the upper end surface of PU membrane is provided with and applies mud, the internal diameter of prevention of seepage circle is the same with the external diameter of applying mud, and the centre of a circle of prevention of seepage circle is the same with the centre of a circle position of applying mud. According to the breathable adhesive tape with good waterproof effect, the anti-seepage ring and the release paper are fixed together, and when the breathable adhesive tape is idle, the anti-seepage ring is sleeved on the outer wall of the mud application. However, when the existing adhesive tape is used, the adhesive on the adhesive tape is easy to adhere to skin, the adhesive in the adhesive tape usually contains chemical substances, such as formaldehyde, benzene and the like, which can cause irritation to the skin, so that the skin can possibly have discomfort symptoms of redness, itching, pain and the like, and therefore, the novel waterproof breathable adhesive tape is provided. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a novel waterproof breathable adhesive tape, which solves the problems proposed by the background technology. The novel waterproof breathable adhesive tape comprises a super-hydrophobic non-woven fabric layer, a permanent adhesive layer is arranged below the super-hydrophobic non-woven fabric layer, a PU film layer is arranged below the permanent adhesive layer, a separation ring is arranged below the PU film layer, a medical pressure-sensitive adhesive layer is arranged in the separation ring, a skin-friendly non-woven fabric layer is arranged below the medical pressure-sensitive adhesive layer, a plurality of uniformly distributed small holes are formed in the skin-friendly non-woven fabric layer, and the small holes penetrate through the skin-friendly non-woven fabric layer. As a further technical scheme of the utility model, the super-hydrophobic non-woven fabric layer forms a micro-nano level coarse structure on the surface of the super-hydrophobic non-woven fabric layer through chemical vapor deposition, plasma treatment or other micro-nano structure forming technologies, and is coated with a layer of low-surface energy substance. As a further technical scheme of the utility model, the PU film layer has a micropore structure.
