[0002] Coil coating is a kind of coating used for indoor and outdoor decoration after coating the surface of steel plate and aluminum plate to make pre-coated coil. Aluminum coil is widely used in the decoration industry due to its light weight, diverse colors and surface states. It is increasingly favored by people. As people's requirements for quality of life are getting higher and higher, coating layers with ordinary effects can no longer meet people's requirements. Some coatings with special effects on the surface are more and more popular. Love

preparation example Construction

[0051] like figure 1 Shown, a kind of preparation method of aluminum coil coating is characterized in that: comprise the following steps,

[0052] Step 1: Pre-soak the aluminum-silver paste; take the aluminum-silver paste according to the weight percentage and add the solvent to soak it, stir it at a slow speed and place it for 3-5 hours, such as: leave it for 4 hours, continue to stir it evenly, take a sample, fully wet it and set aside ;

[0053] Step 2: pre-mixing; adding the polyester resin and amino resin into the dispersion kettle by weight percentage, and stirring evenly;

[0054] Step 3: Use a mixer to stir at a speed of 80-120 RPM, such as: stir at a speed of 100 RPM. During the stirring process, put the aluminum silver paste wetted in the above step 1 into the dispersion kettle, and stir for 8-15 minutes, such as: stir 10 minutes;

[0055] Step 4: Put the pearlescent powder into the dispersing kettle according to the weight percentage, and use the mixer to stir ev...

Embodiment 1

[0060] Embodiment 1: a kind of coating for aluminum sheet coil, it is coated with golden flash diamond three-dimensional shell pattern paint as coil roll, comprises following component and important percentage thereof: polyester resin 72%, adhesive agent 2%, aluminum silver paste 8% , 0.5% defoamer, 6% solvent, 1% texture aid, 6% amino resin, 2% golden dye, 2% pearl powder, and 0.5% catalyst.

[0061]The above polyester resin is a medium molecular weight polyester with a solid content of 80% and a viscosity of 5000-6000pa.s / 25°C. The aluminum silver paste is a silver round aluminum silver paste with an inner diameter of 35um. The solvent is a mixed solvent of butyl ester and PMA. The ratio is 3:1; the amino group is permethylether melamine formaldehyde resin, the adhesive is epoxy-modified phosphate polymer, the defoamer is acrylic polymer, and the graining aid is silicone Modified compound; the golden yellow dye is an organic aromatic compound, and the pearl powder is a white...

Abstract

The present invention relates to an aluminum plate and coil coating and a preparation method thereof, comprising the following components and their weight percentages: polyester resin: 70-80%; aluminum silver paste: 5-9%; amino resin: 5-9%; solvent : 5‑8%; Golden dye: 1‑3%; Pearlescent powder: 1‑3%; Texture aid: 1‑3%; Adhesive agent: 1%‑2%. Coil coating, the coating has bright colors, strong flashing feeling, and has a three-dimensional concave-convex coating effect; moreover, the coil coating forms a golden flashing diamond three-dimensional shell pattern paint effect, and it adopts high-solid and low-viscosity linear polyester resin , itself has good flexibility, which can meet the construction requirements of aluminum plate decorative bending performance.

Description

technical field [0001] The invention relates to the technical field of fine chemical coatings, in particular to an aluminum coil coating and a preparation method thereof. Background technique [0002] Coil coating is a kind of coating used for indoor and outdoor decoration after coating the surface of steel plate and aluminum plate to make pre-coated coil. Aluminum coil is widely used in the decoration industry due to its light weight, diverse colors and surface states. It is increasingly favored by people. As people's requirements for quality of life are getting higher and higher, coating layers with ordinary effects can no longer meet people's requirements. Some coatings with special effects on the surface are more and more popular. Love. Contents of the invention [0003] The object of the present invention is to provide a coating for aluminum coils with bright colors, strong flickering effect and three-dimensional concave-convex coating effect. [0004] Another objec...
