Problems solved by technology

Because the production process of the aluminum spraying transfer method is relatively complicated, the technology content is high, the equipment investment is large, and the production cost is very high. At the same time, the existing spraying method has high requirements for the adhesive, and a small amount of organic solvent remains in the adhesive solution. , easy to cause environmental pollution, and cannot meet the requirements of green environmental protection

Abstract

A disclosed coating for aluminium plated paper is characterized by comprising the following compositions in parts by weight: 15-25 parts of an acrylate, 20-40 parts of nitro cellulose, 15-25 parts of polyurethane, 5-10 parts of acrylic acid, 20-30 parts of an acrylate emulsion, and 90-110 parts of an alcohol solution. According to the technology, alcohol is employed as a solution and can be completely reacted with the acrylate, no toxic solvent is generated and environment is not polluted. The acrylate emulsion and the acrylate are employed at the same time as glue materials, are further reacted with the solution while the binding purpose is reached, and no toxic solution is left in the binder.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to the field of vacuum-sprayed aluminum-sprayed paper materials. Background technique [0002] Vacuum aluminum-sprayed paper, or aluminum-sprayed paper, aluminum-coated paper, and vapor-deposited paper, is a new type of green packaging material that has been more and more widely used in the packaging industry in the world since the 1980s. Because of its noble and beautiful metal texture, stable and reliable printing performance, and degradable and recyclable environmental protection properties, it is more and more popular among people. Aluminum-sprayed paper uses less aluminum and has good degradability, which can save production costs and will not cause environmental pollution. It is an environmentally friendly green packaging material and an alternative and upgraded packaging material for aluminum foil composite paperboard. Aluminum-sprayed paper has good gloss and smoothness, ...
