Problems solved by technology

[0003] At present, the common decorative film is PVC decorative film. This kind of decorative film can make the surface of the decorated object obtain higher hardness, prevent the surface from being artificially scratched, scratched or bumped, so as to better protect the decorated object and increase its durability. service life; but this kind of decorative film can only play the role of beautiful decoration, without additional functions, and its weather resistance and high temperature resistance need to be further improved, the surface smoothness and gloss are insufficient, and the surface of the film feels rough. In addition, its effect on the printing layer The adhesion is weak, and the clarity of graphics and ink firmness need to be further improved; in addition, because it contains chlorine elements inside, it has a good flame retardant effect, but its environmental protection is poor
[0004] Chinese invention patent CN 109280289 A discloses a zero-shrinkage decorative film. According to the weight ratio, its raw materials are: 100 parts of PVC glue, 6-12 parts of zinc powder, 2-3 parts of epoxy soybean oil, and 2 parts of nano-calcium carbonate. -6 parts, 5-10 parts of titanium dioxide, 2-6 parts of colorant, 20-40 parts of plasticizer, 2-4 parts of cadmium barium zinc composite stabilizer, 20-40 parts of processing aid, which pass the formula, especially It is the addition of processing aids to make the decorative film zero shrinkage and prolong the service life of the decorative film. However, the composition of this material is relatively complex, and the amount of additives is large. During long-term use, these additives are easy to seep from the substrate. out, thereby affecting the service life of the material, and it does not have the effect of absorbing ink, and does not improve the clarity and firmness of the printed layer graphics
