Problems solved by technology

[0006] Although there are existing technologies about water-based coatings for vacuum aluminum-coated paper, there is no solvent-based coating in the actual application process. The most important thing is that once the color paste and other components are added to the water-based coating , its color rendering effect is often unsatisfactory

preparation example Construction

[0041] The present invention also provides a kind of preparation method of above-mentioned golden water-based paint, comprising:

[0042] Step 1: Mix and stir the water-based resin, water and the co-solvent accounting for 30-50% of the total weight of the co-solvent for 2-3 hours;

[0043] Step 2: Mix the two color pastes and add wetting agent, rheology control agent and anti-scratch agent in sequence. After stirring for 3-5 hours, add 10-20% of the total weight of the co-solvent and continue Stir for 1 hour;

[0044] Step 3: Slowly add the color paste mixture prepared in step 2 to the resin mixture prepared in step 1, stir for 1-2 hours, then add defoamer and remaining additives, and then stir for 3-5 hours;

[0045] Step 4: Slowly add a pH regulator until the pH of the mixture is 7-8, and then stir for 0.5 hours;

[0046] Step 5: filtering to obtain the golden water-based paint.

Abstract

The invention provides golden water-based paint for vacuum aluminized paper. The golden water-based paint comprises the following components: water resin, a defoaming agent, a wetting agent, a rheology controller, an anti-scratch agent, a pH adjusting agent, a co-solvent, a mill base and water, wherein the water resin is water polyacrylic emulsion and water polyurethane emulsion, and the weight ratio of the water polyacrylic emulsion to the water polyurethane emulsion is (5 to 15):(30 to 52); the mill base is water transparent yellow pigment and a water transparent red pigment, and the weight ratio of the water transparent yellow pigment to the water transparent red pigment is (1 to 5): (1 to 5). The invention also provides a preparation method of the golden water-based paint. The golden water-based paint not only can present a pure golden gloss in the paper vacuum aluminizing process, but also is uniform in color, and is excellent in a decoration effect and has the advantages of good abrasion resistance, adhesiveness, printing surface strength and the like.

Description

technical field [0001] The invention relates to a coating, in particular to a golden water-based coating for vacuum aluminum-plated paper and a preparation method thereof. Background technique [0002] Vacuum aluminum-coated paper, as a kind of metallic luster paper, is a high-grade and novel packaging material developed in recent years. Due to the combination of metal aluminum and paper, it not only has excellent air barrier performance, but also has the characteristics of bright color, strong metallic feeling, bright and elegant printed matter, so it can replace large-area bronzing of printed matter and play an important role in the beautification of products. The role of icing on the cake is widely used in the outer packaging and labels of wine, tobacco, food, medicine and daily necessities. Vacuum aluminum-coated paper is different from aluminum-mounted cardboard and PET laminated paperboard: aluminum-mounted paperboard is directly composited with aluminum foil and pape...
