Problems solved by technology

[0005] In the process of composite cardboard, the front of composite cardboard contains glue, aluminum foil or aluminized film or transferred aluminum layer, which has good airtightness and can keep the moisture in the cardboard from losing; while composite cardboard The reverse side is just cardboard, without any airtightness, good air permeability, and poor water retention
Therefore, the moisture in the composite cardboard is easy to lose from the back or the moisture from the outside

Abstract

The invention discloses a water-based acrylic paint for composite paperboards. The technical scheme is as follows: the water-based acrylic paint for composite paperboards comprises the following components in percentage by weight: 5-20% of styrene-acrylic acid copolymer emulsion, 20-35% of self-crosslinked acrylic acid dispersing agent, 40-60% of water, 0.1-0.5% of water-based leveling agent, 0.3-0.8% of water-based defoaming agent, 1.0-3.0% of water-based hydrophobing agent and 0.1-1% of water-based anti-wear agent. The water-based acrylic paint for composite paperboards can well balance the moisture in the paperboard, keep the paperboard flat and prevent the paperboard from warping, curling and the like, has certain smoothness, and is coated on the back surface of the composite paperboard. The invention also discloses a preparation method of the water-based acrylic paint for composite paperboards.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of coatings for composite processing, and specifically relates to a water-based acrylic coating for composite cardboard and a preparation method thereof. [0003] 【Background technique】 [0004] With the improvement of people's living standards, the requirements for quality of life are also getting higher and higher. In the fields of packaging and printing such as cigarette packaging, food packaging, pharmaceutical packaging, cosmetic packaging, etc., more and more composite cardboard is used for packaging. The so-called composite cardboard usually refers to cardboard made by laminating aluminum foil and aluminum-plated film on the surface of various white cardboard or coated paper; or the aluminum layer in the transfer aluminum-plated film is transferred to the card through glue. The paper is made into transfer aluminized paper. [0005] In the process of composite cardboard, the front side of composite card...
