The embodiment of the present invention discloses a
label film for the surface of a car sunshade and a preparation method thereof, comprising a first combination layer and a second combination layer connected in sequence; and the first combination layer at least comprises an
adhesive layer adhered to the surface of the car sunshade and a deformable soft paste layer arranged on the
adhesive layer; the second combination layer at least comprises a marking layer, and a slow-release
adhesive layer group arranged between the soft paste layer and the marking layer, and the slow-release adhesive
layer group comprises at least a thermal conductive material. The preparation method comprises: S100, compounding an adhesive layer on the soft paste layer to obtain a first combination layer; S200, laminating the marking layer on the slow-release adhesive
layer group to form a second combination layer; S300, laminating one side of the soft paste layer facing away from the adhesive layer with one side of the slow-release adhesive layer group facing away from the marking layer to obtain a
label film for the surface of a car sunshade. The effects of good
environmental protection, good adhesion effect, and excellent high
temperature resistance are achieved, and the marking effect is increased.
