Problems solved by technology

However, the matching between the current laser anodized aluminum coating and the UV varnish on the substrate is poor, which makes the laser coating easy to scratch and fall off, and it is easy to cause problems such as blurred patterns or unclear cuts. Adhesives used in the contact backing layer are studied

Abstract

The invention relates to the technical field of anodized aluminum hot stamping, more specifically, the invention relates to an adhesive used for laser anodized aluminum coating and a preparation method thereof. The preparation raw materials of the adhesive include resin and diluent; the invention provides an adhesive, which is used for laser anodized aluminum coating and substrate varnish by using a certain content of resin and plasticizer as adhesive material When bonding, the diluent can quickly volatilize, and the resin and plasticizer are evenly wetted between the coating and the substrate, forming a high adhesion with the anodized aluminum coating and varnish, which is beneficial to the adhesion between the anodized aluminum coating and the varnish Efforts should be made to avoid peeling or peeling of the paint; and the applicant found that by selecting a suitable resin and plasticizer, it is also conducive to the integrity of the hot stamping pattern, bright color, clear edges of the pattern, and good cutting performance.

Description

technical field [0001] The invention relates to the technical field of anodized aluminum hot stamping, more specifically, the invention relates to an adhesive used for laser anodized aluminum coating and a preparation method thereof. Background technique [0002] Anodized aluminum is a hot stamping material made of coating and vacuum evaporation on a film base and adding a layer of metal foil. Laser anodized aluminum is laser molded on the coloring layer, so that the hot stamping pattern has a flowing rainbow effect, metallic luster and strong three-dimensional effect. It is widely used in the printing and packaging industry, in food, medicine, daily chemical products, tobacco and wine, clothing, Industries such as gift packaging and decorative materials have been promoted rapidly. [0003] The principle of the hot stamping process is: by heating the hot stamping plate to 100°C to 150°C, the film material in contact with the hot stamping plate is heated, first the peeling l...
