Problems solved by technology

However, the basic performance of the adhesive layer in anodized aluminum is the ease of transferring it to the substrate and whether it can get clear patterns and texts. Although the adhesive layer prepared by some companies does not have harmful volume residues to the human body and is conducive to environmental protection, it is still Its printing performance is not high, and there are problems such as unclear patterns and characters

Abstract

The invention relates to the field of dye, coating and adhesive, in particular to aqueous adhesive for electrochemical aluminum, and provides environment-friendly aqueous adhesive for electrochemical aluminum and a preparation method thereof. Compared with the conventional solvent type adhesive, the aqueous adhesive is environmental protection and low cost; and meanwhile, compared with common aqueous coating, the aqueous adhesive has the advantages of good printing adaptability, wide thermoprinting temperature range, good thermoprinting effect and easy control of production process. The invention adopts the following technical means that: the formula of the aqueous adhesive comprises the following components in part by weight: 30 to 35 parts of aqueous resin, 42 to 47 parts of water, 18 to 23 parts of cosolvent, 2 to 4 parts of white carbon black and 0.01 to 0.02 part of defoaming agent; and the preferable formula of the aqueous adhesive comprises the following components in part by weight: 32 to 34 parts of aqueous resin, 44 to 46 parts of water, 20 to 22 parts of cosolvent, 2 to 3 parts of white carbon black and 0.015 to 0.02 part of defoaming agent.

Description

technical field [0001] The invention relates to the fields of dyes, coatings and adhesives, and more specifically relates to a water-based adhesive for anodized aluminum. Background technique [0002] At present, in my country, a large amount of organic solvents are used in the production process of the anodized aluminum industry. The products produced usually contain residues of various volatile organic compounds (VOCs). A large amount of organic solvents are used. On the one hand, the residues will invade the human body and cause cumulative Poisoning, on the other hand, also has the problem of higher solvent cost. For example, the application number is 2008100160540.1 (a thermal transfer hot stamping adhesive for anodized aluminum and its preparation method), the patent number is 200610116808.1 (an adhesive for an anodized aluminum coating and its preparation method), and the application number is 200810048922.4 (Holographic Positioning Electrochemical Aluminum High-speed ...
