Description
Technical field
The invention belongs to environmentally friendly aluminium paint fields, and in particular to a kind of aqueous light UV solidifications aluminium paint;In addition, this hair
The bright preparation method and application method for also relating to the aqueous light UV solidifications aluminium paint.
Background technology
Aluminium paint is a kind of paint containing aluminium powder, because the good ductility of aluminium can form continuously aluminium in film
Film can cover pin hole, reduce permeability.
Traditional aluminium paint application usually produces the paint vehicle of aluminium paint by alkyd tree usually based on solvent based coating
Fat, solvent and aluminum paste composition, and alkyd resin be with polyacid, unit acid and the raw materials such as polyalcohol in resin reaction kettle into
What row esterification generated.Solvent for use is gasoline, dimethylbenzene, turpentine oil etc., and aromatic solvent is not belonging to film forming matter, used
Solvent can be discharged into air, not only waste resource, but also polluted environment, certain harm can also be caused to human body.
Coating material solidified ultraviolet light (UV) is the liquid oligomer and list caused using ultraviolet initiator in coating system
Free radical polymerization occurs for body to realize that crosslinking curing forms a kind of coating of film, because less or have without using solvent
There are green, environmental protection；Moreover, because using ultraviolet light as energy source is caused, without additional heating, therefore in coating
Energy expenditure can be reduced in solidification process and obtains faster curing rate；Because of these features, UV is coating material solidified in each row
Extensive use is just gradually obtained in industry, especially in consumer electronics product such as laptop, mobile phone industry just gradually
The polyurethane coating of high energy consumption, high VOC emission is replaced to be applied as the principal item of external coating.
Compared with traditional solvent based coating, water paint has price low, safe to use, saves resource and the energy, subtracts
The advantages that few environmental pollution and public hazards, thus have become the Main way of current development coatings industry.Water-base resin system at present
Have water alcohol acid, water soluble acrylic acid, water-base epoxy, waterborne polyurethane resin, aqueous inorganic silicate, water-based fluororesin and it
Modified resin.Acrylic acid（PA）There are wearability, the defect of water resistance and chemical-resistant difference, single polyurethane for lotion
（PU）There is also some shortcomings for lotion, and the gloss retention such as stability, white thickening property and film is poor, and solid content is high, and application range is not wide
Deng.PU and PA has complementation in nature.The advantages of PUA complex emulsions have had both the two, has wear-resisting, corrosion-resistant and light
Bright, soft flexible, water resistance and mechanical mechanics property are good, and weatherability is good etc., and characteristics, a development for becoming current coating become
Gesture.
