Problems solved by technology

[0003] The currently used aluminized transfer adhesives have certain defects in product performance and coating process. Some of them have poor adhesion, and the aluminum foil and paper are peeled off during use, or the aluminum layer falls off during the next process. ; Some transferred paper has poor folding resistance and is easy to break; some coating process is complicated, inconvenient to use, easy to cause waste, or has poor adaptability to the coating compound machine, and sticks to the roll when sizing Wait

Abstract

The invention discloses water-based acrylic aluminized transfer glue and a preparation method thereof, and belongs to the field of adhesive preparation. The transfer glue with 45 to 55 percent of solid content is prepared from monomers, composite emulsifier, initiator, buffering agent, pH regulator, water-based aid and deionized water serving as raw materials by pre-emulsifying, seed reaction, polymerization reaction and compounding; the monomers comprise hard monomer, soft monomer and functional monomer, wherein the hard monomer consists of styrene and methyl methacrylate; the soft monomer consists of ethyl acrylate and butyl acrylate; and the functional monomer consists of any one of acrylic acid and methacrylic acid, any one of hydroxyethyl acrylate and hydroxypropyl acrylate, and N-hydroxymethyl acrylamide. The transfer glue has high bonding force and peeling strength, does not drop, has good coating property, is more convenient for operation, and does not stick rollers.

Description

technical field [0001] The invention belongs to the field of adhesive manufacturing, in particular to a water-based aluminum plating transfer adhesive and a preparation method thereof. Background technique [0002] At present, most of the gold and silver cardboard used for packaging of cigarettes, food, cosmetics and gifts are made of aluminum foil or aluminized plastic film and cardboard directly. The aluminum foil or plastic film on the surface of the cardboard cannot be recycled directly. brought environmental pressure. In recent years, aluminized transfer paper has been widely used as a new type of environmentally friendly packaging material. The main uses of aluminized transfer paper include aluminized transfer beer label paper, aluminized transfer cigarette lining paper, aluminized transfer packaging cardboard, aluminized transfer food packaging paper, etc. It uses the peelability of the aluminum-plated transfer layer to transfer the aluminum layer with various aesth...
