Abstract

The invention relates to an environmentally-friendly aqueous matte aluminized paper undercoating paint and a preparation method as well as application thereof. The paint comprises the following component raw materials in parts by weight: 5-20 parts of aqueous acrylic resin, 0.5-8 parts of neutralizing agent, 50-70 parts of aqueous acrylic emulsion, 10-20 parts of aqueous polyester emulsion, 1-5 parts of aqueous wax slurry, 20-45 parts of cosolvent, 20-80 parts of de-ionized water, 0.1-0.3 part of moistening agent, 0-0.2 part of rheological control agent and 0.05-0.2 part of defoaming agent, and can be used for surface treatment of cigarette inner lining paper. Compared with the prior art, the paint has the advantages of aqueous environmental friendliness, high metal glossiness, superior coverage and wear resistance; and the problem that directly plated paper made by the conventional paint cannot achieve effects of metal feeling and flatness of a matte aluminum foil is solved.

Description

technical field

[0001] The invention relates to an aluminized paper primer for cigarette inner linings, in particular to an environment-friendly water-based matte aluminized paper primer and a preparation method and application thereof. Background technique

[0002] Vacuum aluminized paper instead of aluminum foil composite cigarette lining paper can greatly reduce the use of aluminum, which meets the requirements of environmental protection. Because the aluminum foil composite cigarette lining paper used mostly uses the matte surface of aluminum foil, and the current primer coating for aluminized paper will have defects such as coating lines and bubble points when it is coated with an mesh roller; The aluminum back surface has poor flatness, poor sealability to paper fibers, and high brightness, which cannot achieve the matte and smooth effect similar to aluminum foil.
