The invention relates to the technical field of
thermal transfer printing
lettering film, and in particular, relates to a high-elasticity
silicone rubber
lettering film and a preparation method and anapplication method thereof. The high-elasticity
silicone rubber
lettering film comprises a load-bearing substrate, a release layer, a
surface layer silicone rubber ink layer, an anti-photopermeable
silicone rubber ink layer, an
adhesive interfacial agent layer and a TPU
hot melt adhesive film which are connected from bottom to top successively; the
adhesive interfacial agent layer is prepared from an adhesive interfacial agent, and the adhesive interfacial agent is an adhesive interfacial agent containing dual-resin components. The
silicone rubber lettering film has the advantages of both thesilicone
rubber material and the TPU material, has good elasticity, tearing strength, weatherability, yellowing resistance,
water washing resistance and other comprehensive properties, has
layers noteasy to separate, is not easy to discolor or fade by
sunlight exposure, and has the water-washing
fading rate not less than 0.5%, is not easy to dye when being mixed and washed with materials with other colors, and is high in stability, easy to bond with a variety of materials, high in
bonding strength, not easy to peel off, good in stability, delicate in hand feeling, good in aesthetic degree, and long in service life.
