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
The present invention relates to a kind of paint.Specifically, be a kind of thermosetting acrylic coating that is used for roller coat at aluminium foil surface, be particularly useful for the aluminium foil surface application of the following thickness of 0.1mm.
Background technology
In building trade, plastic-aluminum sheet material has been widely used as finishing material.For reducing cost, require the aluminium foil on the aluminium-plastic panel thin as much as possible, brought into use the aluminium foil of the following thickness of 0.1mm at present.For improving the decorative effect of plastic-aluminum sheet material, often need at aluminium foil surface roller coat one coating.For enhancing productivity, require roller coat to be dried at short notice again at the coating of aluminium foil surface.Traditional method is in roll coat enamel, and the aluminium foil that makes the surface have coating passes through drying tunnel, thereby the coating on the aluminium foil is dried rapidly.Because aluminium foil is very thin, require the temperature of drying tunnel can not be too high, temperature one height can cause the aluminium foil distortion.
At present, the coating that is used for the aluminium foil surface application mostly is the polyester lacquer, because resinous molecular structure is big in the polyester lacquer, (OH) be positioned at two of molecule, the structure of molecular backbone chain be a flexibility to play the functional group of crosslinking reaction.Flexible macromole (OH) easily is curled in the formed molecular coil of macromolecular chain functional group.When having only temperature to raise, molecular coil could be loose, make functional group (OH) with the polyester lacquer in the aminoresin butoxy react.So the polyester lacquer only could react (oven dry) film forming under 232～241 ℃ comparatively high temps.So high film forming (oven dry) temperature can cause the aluminium foil distortion.Therefore, the polyester lacquer can only be used for the application than thick aluminum foil, can not be used for the application of the thin aluminium foil of the following thickness of 0.1mm, and the scope of application is wideless.
Summary of the invention
The object of the present invention is to provide a kind of thermosetting acrylic coating.This thermosetting acrylic coating, film forming (oven dry) temperature is low, can be used for the above application than thick aluminum foil of 0.1mm, can be used in again on the following thin aluminium foil of 0.1mm, and the scope of application is wider.
For achieving the above object, the present invention adopts following technical solution:
Thermosetting acrylic coating of the present invention is made by the raw material of following parts by weight:
50～60 parts of thermosetting acrylic resins, 15～20 parts in butoxy aminoresin, 5～28 parts of pigment, 5～10 parts of solvents, 0.2～0.4 part of flow agent, 0.2～0.4 part of defoamer, 0～3 part of adhesion promoter, 0～4 part of wetting dispersing agent.Wherein: said pigment is titanium dioxide or flash of light aluminium powder etc.; Said solvent is dimethylbenzene, S-100 high boiling aromatic hydrocarbon solvent, butyl glycol ether, ethylene glycol ether acetate etc.
Adopt such scheme, have the following advantages:
Because the thermosetting acrylic resin in the present invention's prescription, its molecular chain are flexible little macromolecular chain, and its functional group (OH) is positioned on the side chain of macromolecular chain, is difficult for being wrapped up by a macromole ball of string, can not make functional group's (reactive behavior decline OH).Therefore, and its functional group (with the butoxy functional group of aminoresin the needed activation energy of chemical reaction takes place OH), more much lower than the polyester lacquer.So the needed Heating temperature of reaction film forming is just low, has only 190～200 ℃.Thereby, be coated on the aluminium foil with thermosetting acrylic coating of the present invention, be reacted in the membrane process and can not make the aluminium foil temperature distortion.Not only can be used for the application of aluminium foil thicker more than the thickness 0.1mm, also can be used for the application of the thin aluminium foil of the following thickness of 0.1mm, the scope of application is wider.
