Abstract

The invention provides low-temperature hot stamping hot melt adhesive for alumite and a preparation method of the low-temperature hot stamping hot melt adhesive. In the existing alumite rotary gold stamping process, heat transfer hot stamping temperatures are all within the range of 120 DEG C to 200 DEG C, if the temperature of a gold stamping plate is too high, energy consumption in the gold stamping process is increased, alumite hot stamping foil or printing materials can deform by being heated, and then hot stamping is inaccurate. The low-temperature hot stamping hot melt adhesive is prepared from the following raw materials, by weight, 1-6 parts of chloroethylene-vinyl acetate resin, 1-10 parts of terpene resin, 1-10 parts of acrylic ester, 1-5 parts of nitrocellulose, 1-5 parts of fumed silica, 20-70 parts of ethyl acetate, 10-50 parts of ethyl alcohol and 1-5 parts of propyl acetate. The low-temperature hot stamping hot melt adhesive is low in softening temperature and high in adhesive power, heat transfer hot stamping temperatures are within the range of 85 DEG C to 100 DEG C, energy consumption can be remarkably reduced, the problems that the gold stamping foil or the printing materials easily deform by being heated by high-temperature hot stamping, so that waste caused by inaccurate hot stamping is generated are solved.

Description

technical field [0001] The invention relates to the field of hot-melt adhesives, in particular to a low-temperature stamping hot-melt adhesive for anodized aluminum and a preparation method thereof. Background technique [0002] Anodized aluminum is a new type of packaging material for vacuum aluminum plating. After a certain temperature and pressure, the pre-engraved patterns, lines and fonts on the hot stamping plate are transferred to the surface of the substrate, making it bright in color, strong in metal feeling, visually It has been widely used in hot stamping and decoration on the surface of paper products, plastic products, leather products, wood products and so on. [0003] Anodized aluminum is composed of a base film layer, a release layer, a colored layer, an aluminum-coated layer and a hot-melt adhesive layer. , and then coat the hot-melt adhesive layer. The hot-melt adhesive mainly plays the role of bonding. In anodized aluminum hot stamping, it is heated and ...
