Problems solved by technology

However, this process has a series of defects such as strong solvent odor, high cost (expensive, coating amount of 10 g / square), large VOC (volatile organic compound) residue, and easy safety accidents caused by gas concentration. Metal substrates are prone to problems such as large color difference and uneven coating on the surface of the product due to factors such as unclean aluminum foil oiling and differences in batch pressing processes, which limit the promotion and application of the product

Abstract

The invention discloses full water-based system coated composite aluminum foil paper and a preparation process thereof. The composite aluminum foil paper is prepared by fully adopting a water-based process. The preparation process comprises the following steps: pre-coating one surface of an aluminum foil with a layer of adhesive by adopting a wet-process based laminator, adhering the aluminum foil and a white paperboard together by the adhesive in a laminating way, drying with a dryer, standing, curing for 12-24 hours, coating the other surface of the aluminum foil with a layer of prepared paint, shaping, and packaging to obtain the finished product. A series of problems of strong smell, high cost, high VOC residue, occurrence of safety accidents due to gas concentration, great color difference on surfaces of products and nonuniform coating of a traditional oil-based process can be solved.

Description

technical field [0001] The invention belongs to the field of aluminum foil composite wrapping paper processing, and in particular relates to an all-aqueous system coated aluminum foil composite paper and a preparation process thereof. Background technique [0002] The existing aluminum foil composite gold and silver cardboard is widely used in cigarette packs, some high-end wines, medicines, cosmetics, gift packaging and other fields. Due to the unique metal effect and base material on the surface of aluminum foil, its production process has been limited to oily process, and the main solvents are ethyl acetate, n-propyl ester, butanone, propylene glycol methyl ether, etc. However, this process has a series of defects such as strong solvent odor, high cost (expensive, coating amount of 10 g / square), large VOC (volatile organic compound) residue, and easy safety accidents caused by gas concentration. Metal substrates are prone to problems such as large color difference and un...
