Fig. 1 is a schematic diagram of an embodiment of the present utility model. The embodiment provides a composite film for decorating and finishing skin feel, which comprises a composite film body, wherein the composite film body has a five-layer structure, and comprises a PVC bottom layer 5, a glue layer 4, a PET layer 3, a bottom coating 2 and a top coating 1 from bottom to top. The underside of the top coat 1 is bonded to the upper side of the primer layer 2, the underside of the primer layer 2 is bonded to the upper side of the PET layer 3, the underside of the PET layer 3 is bonded to the upper side of the glue layer 4, and the underside of the glue layer 4 is bonded to the upper side of the PVC layer 5.

The composition of the surface coating 1 is a coating formed by mixing 70 parts of polycarbonate resin and 20 parts of poly (isocyanate) and 10 parts of ethyl acetate, and the material has the functions of strong flexibility, wiping resistance, disinfection resistance (50 times of alcohol wiping), better touch feeling effect and better adhesion after being cured at a high temperature of 80-120 ℃. The overall thickness is 3 microns to 5 microns.

The primer layer 2 is a polyurethane coating, and the material has strong flexibility and good adhesive force after being cured at a high temperature of 90-110 ℃, and is a connecting layer of the surface coating 1 and the PET layer 3, so that the adhesive force between the two layers is enhanced. The thickness of the primer layer 2 was 12 μm.

The PET layer 3 is used as a barrier layer, is made of a biaxially oriented PET film layer with barrier property, has extremely low permeability to gas and water, and effectively prevents permeation of harmful substances. The thickness of the PET layer 3 was 25 microns.

The glue layer 4 is made of polyurethane bi-component glue, has strong flexibility and high bonding fastness, and is a connecting layer of the PET layer 3 and the PVC bottom layer 5, so that the adhesive force between the two layers is enhanced. The thickness of the glue layer 4 is 3 to 5 micrometers.

The PVC film bottom layer 5 has good acid resistance, disinfection resistance, corrosion resistance and corrosion resistance, decorative and wear-resistant properties, and the stability of the material is maintained. The thickness of the PVC film bottom layer 5 is 80 micrometers to 200 micrometers, and the PVC film bottom layer is a semi-hard or soft PVC film.

The skin feel composite film provided in this example was prepared by the following process and parameters.

The process flow is as follows: unreeling the PET layer 3, coating the bottom coating 2, drying, coating the top coating 1, drying, coating the glue layer 4, drying, compounding the PVC bottom layer 5, reeling, curing, slitting and reeling.

According to the utility model, through the arrangement of the top coating, namely the skin feel layer, in the decorative film, as the slip feel auxiliary agent is added in the top coating, the effect of good touch feel is achieved, the harmonious perception of human bodies and surrounding environments is fully created, and the problems of poor feel and similar to plush feel under the prior art are solved.

Through the setting of the two-component polyurethane coating in the surface coating, because the resin coating has stronger flexibility, after high-temperature curing, the resin coating has better adhesive force (hundred-cell experiment level 5), scratch resistance and disinfection resistance (alcohol wiping 50 times) and good processability (0T bending), can have very big promotion effect on the reservation of the surface of the decorative film, greatly reduces the risk of failure caused by the surface abrasion of the decorative film, and prolongs the service life of the decorative film.
