Abstract

The invention discloses a laser alumite hot stamping back gum and a preparation method thereof. The laser alumite hot stamping back gum comprises the raw materials: a maleic anhydride-vinyl acetate-methacrylate copolymer, a chloroprene-acrylic acid-acrylate copolymer, fumed silica and a solvent; the maleic anhydride-vinyl acetate-methacrylate copolymer comprises the raw materials by weight: 1 to 2parts of maleic anhydride, 1 to 2 parts of vinyl acetate and 5 to 8 parts of methacrylate monomers; the chloroprene-acrylic acid-acrylate copolymer comprises the raw materials by weight: 2 to 4 partsof chloroprene, 2 to 4 parts of acrylic acid and 4 to 8 parts of acrylate monomers. The laser alumite hot stamping back gum has good adhesive force and stripping resistance, and when the back gum isused, the hot stamping effect is good, and the definition is high; the softening point is proper, and the anti-adhesion phenomenon is avoided.

Description

technical field [0001] The invention relates to the technical field of anodized aluminum hot stamping adhesive for packaging, in particular to a laser anodized aluminum hot stamping adhesive and a preparation method thereof. Background technique [0002] At present, with the development of modern science and technology and the improvement of packaging and decoration grades, laser anodized aluminum hot stamping foil is based on the production technology of ordinary anodized aluminum hot stamping foil, combined with laser technology, laser molding technology, chemical raw material industry and chemical industry.
