Problems solved by technology

Such a high film-forming (drying) temperature will cause deformation of the aluminum foil
Therefore, polyester paint can only be used for the coating of thicker aluminum foil, and cannot be used for the coating of thinner aluminum foil with a thickness below 0.1mm, and the scope of application is not wide

Embodiment Construction

[0010] First example:

[0011] Select 50 parts of thermosetting acrylic resin, 20 parts of butoxylated amino resin, 6 parts of pigment, 10 parts of solvent, 0.2 part of leveling agent, 0.3 part of defoamer and 3 parts of adhesion promoter. use.

[0012] First put the thermosetting acrylic resin, pigment and solvent into the container, stir with a high-speed disperser for 30 to 50 minutes, mix evenly, and make a mixture;

[0013] Then use a sand mill to grind the above-mentioned mixture to a fineness below 15 microns;

[0014] Then, pump the sanded mixture into the paint mixing pot, add leveling agent, defoamer and adhesion promoter, and stir evenly for 30 to 40 minutes to prepare the aluminum foil surface coating of the present invention. Installed thermosetting acrylic paint.

[0015] In this embodiment: the pigment used can be determined according to the needs, it can be titanium dioxide or flash aluminum powder, it can also be phthalocyanine blue, medium chrome yellow, e...

Abstract

The invention discloses a thermosetting a crylic acid coating roll-coated on aluminum foil surface and painting the aluminum foil surface. It is made from thermosetting a crylic acid resin 50-60shares, butoxy amino resin 15-20shares, pigment 5-28shares, solvent 5-10shares, levelling agent 0.2-0.4share, defoaming agent 0.2-0.4share, adhesion accelerant 0-3shares, and wet dispersing agent 0-4shares. The pigment is titanium pigment or flashlight aluminum powder; the solvent is xylene, S-100 high boiling arene solvent, butyl glycol ether or ethylene glycol ethyl ether acetic acid. It has wide application range.

Description

technical field [0001] The invention relates to a paint. Specifically, it is a thermosetting acrylic coating used for roller coating on the surface of aluminum foil, especially suitable for coating the surface of aluminum foil with a thickness below 0.1mm. Background technique [0002] In the construction industry, aluminum-plastic panels have been widely used as decorative materials. In order to reduce the cost, the aluminum foil on the aluminum-plastic plate is required to be as thin as possible. At present, aluminum foil with a thickness of less than 0.1mm has been used. In order to improve the decorative effect of aluminum-plastic panels, it is often necessary to roll-coat a layer of paint on the surface of the aluminum foil. In order to improve production efficiency, it is also required that the paint rolled on the surface of the aluminum foil be dried in a short time. The traditional method is to make the aluminum foil with the paint on the surface pass through the ...
