Abstract

The invention relates to a skin-simulating function film and a preparation method thereof. The skin-simulating function film comprises a skin-simulating base material layer and a pressure-sensitive glue layer compounded on the surface of the skin-simulating base material layer, wherein release paper or a release film covers outside the pressure-sensitive glue layer, a backing layer is arranged outside the skin-simulating base material layer, the moisture permeation ratio of the skin-simulating function film is 500g / m<2>*24h-2,000g / m<2>*24h, and the air permeability of the skin-simulating function film is not less than 2,000mL / m<2>*24h.0.1MPa. Through using the skin-simulating base material layer with skin similar physiological function air permeability, moisture permeation and good biocompatibility and matching with the pressure-sensitive glue layer, the prepared skin-simulating function film is high in comfort and good in effect during using.

Description

technical field [0001] The invention belongs to the joint application field of polymer materials and cosmetics, and in particular relates to a skin-imitating functional film and a preparation method thereof. Background technique [0002] At present, there are some deficiencies in the film products commonly used by people. For example, the film care products used for facial care mostly use non-woven fabrics or textile materials as substrates, and then use konjac glue, hyaluronic acid, polyacrylic acid, seaweed glue, etc. to make them. Form a gel film for facial care and maintenance to achieve the effect of nourishing the skin and beautifying the skin. But its veneer adhesion is too small, easy to fall off. Therefore, it is of great significance to study a skin-like functional film that has moderate moisture permeability and air permeability, and can also take into account adhesion and comfort. Contents of the invention [0003] The technical problem to be solved by the pr...
