Abstract

The invention belongs to the technical field of high polymer materials, and relates to an alumite sticky layer coating and a using method, in particular to an alumite sticky layer coating containing acrylic monomers. The alumite sticky layer coating is prepared from, by mass, 40-60 parts of acrylic monomers, 1-4 parts of silicon oxide powder, 1-6 parts of rosin and 50-70 parts of a dispersion solvent. The invention further discloses a using method of the alumite sticky layer coating containing the acrylic monomers. Various auxiliary materials and acrylic resin are adopted for forming the alumite sticky layer coating with the excellent stamping performance according to the certain ratio, and acrylic resin with the single good stamping performance is converted into the alumite sticky layer coating with the good stamping performance, slitting performance, adhesive force and stripping performance. According to industrial application, compared with common alumite, alumite obtained through the alumite sticky layer coating containing acrylic monomers overcomes the defects of not solid hot stamping, leakage stamping and the like and has the obvious advantage.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to an anodized aluminum bonding layer paint and a use method thereof, in particular to an anodized aluminum bonding layer paint containing an acrylic monomer and a use method thereof. Background technique [0002] Anodized aluminum hot stamping products are increasingly becoming the new favorite in the packaging material industry due to their many advantages such as exquisite patterns, clear lines, high color saturation and strong metallic texture. They are widely used in many fields, whether it is paper, leather, wood or metalware. The surface is more or less decorated with anodized aluminum bronzing. Due to the differences in surface texture and material performance of different bronzing objects, and different bronzing patterns also have requirements for the characteristics of anodized aluminum, when making anodized aluminum bronzing products, it is often necessary to find...
