Abstract

The invention provides a waterborne adhesive for anodized aluminum as well as a preparation method and a use method of the waterborne adhesive. The waterborne adhesive contains the following components in parts by weight: 38-45 parts of waterborne resin, 0.5-5 parts of a crosslinking agent, 30-45 parts of water, 15-25 parts of a cosolvent and 0.5-2.5 parts of a defoaming agent. The preparation method comprises the steps of mixing the waterborne resin with water according to a formula amount, sequentially adding the cosolvent, the crosslinking agent and the defoaming agent, and mixing until no bubble is generated, so as to obtain the waterborne adhesive. The use method comprises the steps of coating the unglued surface of an aluminum coated layer of an anodized aluminum film with the waterborne adhesive, and carrying out solidification at 130-150 DEG C so as to obtain anodized aluminum coated with the waterborne adhesive. The waterborne adhesive for anodized aluminum simultaneously has a relatively wide stamping temperature range and relatively high binding power, heat resistance and water tolerance.

Description

technical field [0001] The invention belongs to the technical field of anodized aluminum hot stamping, and in particular relates to a water-based adhesive for anodized aluminum, a preparation method and a use method thereof. Background technique [0002] Electrochemical aluminum hot stamping foil has been paid more and more attention in the field of material packaging because of its exquisite appearance and excellent performance. At present, the adhesive layer of the anodized aluminum bronzing foil on the domestic market mainly uses solvent-based coatings. The use of a large number of organic solvents (such as benzene and ketones) makes the products produced usually contain various substances harmful to the human body. Volatile Organic Compounds (VOCs). In addition, the high cost of solvents is also a consideration. Water-based adhesives have become the key research objects of many companies because of their advantages such as no pollution, low price, and the ability to ta...
