Description
Technical field
The invention belongs to paint field, more particularly, to a kind of polyurethane luminous paint.
Background technology
Fluorescent paint is that the fluorescent pigment in being made from it assigns coating with fluorescent functional, can be released under solar radiation
Dazzlingly beautiful honorable coating, in terms of being mainly used in building decoration, road markings, artwork decoration and advertisement landscape lamp.But
In general fluorescent paint is the coating that fluorescence can be sent under ultraviolet irradiation, is not lighted completely then after stopping irradiation, and
Efflorescence is easy under exposure in sunshine.Commonly epoxy fluorescent paint, acrylic acid fluorescent paint currently on the market.Conventional ring
Oxygen tree fat has ehter bond in itself, and sunlight understands saboteur's structure so as to cause the xanthochromia of coating and efflorescence.Acrylic acid fluorescence
Coating glass transition temperature is relatively low, and the long-term exposure of summer sunlight easily softens even tacky.
The content of the invention
In view of this, the present invention is directed to propose a kind of polyurethane luminous paint, chemical resistance performance is good, adhesive force is strong, glimmering
Light fluorescent lifetime is longer, film coated surface flat smooth during use, and film is attractive in appearance.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of polyurethane luminous paint, including component A and B component, component A and B component represent by weight percent：Its
In,
Component A is made up of following component：Hydroxylated acrylic resin 30-45%, fluorescent material 50-65%, thixotropic agent 1-7%,
Defoamer 0.05-0.8%, levelling agent 0.2-0.4%；
B component is made up of following component：Isocyanate curing agent 35-65%, fluorescent material 35-65%, thixotropic agent 0.5-
4%, defoamer 0.2-0.5%, levelling agent 0.3-0.6%, thickener 0.2-6%；
Quality parts ratio between component A and B component is 2~3:1.
Preferably, Hydroxylated acrylic resin is that acrylic monomer is the netted hydroxyl propylene that basis crosslinking forms
Acid resin.
Preferably, isocyanate curing agent is aliphatic isocyanates curing agent, is HDI trimer or HDI biurets.
Preferably, fluorescent material is to contain rare earth-activated alkaline earth metal aluminate system's luminous pigment or rear-earth-doped silicate
Luminous pigment.
Preferably, defoamer is one or more of mixtures in BYK-057 and BYK-066N.
Preferably, levelling agent is one or more of mixtures in BYK-350 and BYK-336.
Relative to prior art, polyurethane luminous paint of the present invention has the advantage that：
Polyurethane luminous paint of the present invention, Hydroxylated acrylic resin and aliphatic isocyanates are selected to combine, energy
Enough color inhibitions, protect fluorescent material that efflorescence does not occur, polyurethane luminous paint of the invention is coated in substrate surface, shows the five colours
Bright-colored effect, surfacing is smooth, product adhesive force≤1 grade of the present invention, can be with continuous illumination 12h, and film acid and alkali-resistance 72h is not
Foaming is not fallen off, and chemical resistance effect is good, and during long-term use, the oxidized xanthochromia of polyurethane fluorescent paint is slow, uses
Time is long and in extensive range.
