Problems solved by technology

However, the existing 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 an aluminum layer appears during the next process. Falling off; 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 poor adaptability to the coating compound machine, and sticking rolls occur during sizing phenomenon
In addition, the traditional product alkylphenol polyoxyethylene ether compound (APEO) emulsifier has certain harm to the environment

Abstract

The invention discloses an acrylic emulsion of a novel transfer adhesive. The acrylic emulsion comprises the following raw materials: alkyl alcohol polyether, lauryl sodium sulfate, a pH regulator, ammonium persulfate, tert-butyl hydroperoxide, sodium hydrogen sulfite, ammonia water and isothiazolinone; inner-core monomers comprise styrene, methyl methacrylate, butyl acrylate, acrylic acid and N-hydroxymethyl acrylamide; and outer-shell monomers comprise styrene, methyl methacrylate, butyl acrylate, acrylic acid and N-hydroxymethyl acrylamide. The acrylic emulsion has the beneficial effect that the solid content is not less than 50%, and the characteristics such as adhesion, transfer and folding resistance are excellent; the acrylic emulsion can be widely applied to transferring to paper products from aluminum-coated layers on polymer base materials such as BOPP (biaxially-oriented Polypropylene) and PET (polyethylene terephthalate), is safe and environmentally friendly, low in VOC (volatile organic compounds) and capable of satisfying the industries with safety and sanitation requirements such as cigarette packaging.

Description

technical field [0001] The invention relates to the field of adhesive preparation, in particular to a novel acrylic emulsion of transfer adhesive and a preparation method. 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 aesthetic effects ...
