The invention provides a kind of outdoor weathe resistance powdery paints, be made up of the component of following mass percent: polyester resin 56% 65%, hydroxy alkyl amide curing agents 3% 3.4%, smooth degasifier 1% 1.5%, levelling agent 1% 1.5%, color stuffing 26.6% 38.5%, Graphene 0.5% 2%.The described powdery paints that the present invention provides has weatherability and the anti-yellowing property of excellence, can be widely applied to the outdoor facilities applications such as outdoor building materials, square building, engineering machinery；Meanwhile, powdery paints of the present invention use safety, low toxicity β hydroxyalkyl amide as firming agent, therefore there is the features such as safe and environment-friendly.
Description
Technical field
The present invention relates to technical field of coatings, particularly a kind of outdoor weathe resistance powdery paints.
Background technology
Powdery paints is the green coating of a kind of non-volatile solvent, has solvent-free, low stain, and stock utilization is high, energy
Amount consumes the advantages such as low.At present, powdery paints application out of doors is increasingly extensive, such as outdoor furniture, means of transportation, vehicle, family
Outdoor building materials coating etc., this just requires that it has stronger weatherability.The weatherability of powdery paints is had more by recent domestic
Research, and successfully develop a series of be applicable to open air powder coating systems, such as polyester/triglycidyl group isocyanide urea
Acid esters (TGIC) system, polyester/esters of acrylic acid system, polyurethane system and fluorine-containing, silicon system etc..
Polyester/TGIC type powdery paints is that in current polyester series, weatherability is a kind of.Polyester and firming agent TGIC
During crosslinking, paint having no volatile substances produces, and can prepare film free of pinholes, and system is homogeneous, stable, adjustable, has good heat-resisting
And weather resistance, the requirement in market can be substantially met.But its strong skin irritation and potential carcinogenecity so that it is raw
Produce and sell and be all greatly affected, become inevitable by market.Wherein, Europe forbids that TGIC is at powdery paints in plain text
In use.
The low toxic and environment-friendly type compound that beta-hydroxy alkylamide (HAA) compound is well recognized as, conduct in art of powder coatings
The firming agent of polyester resin, has the advantages such as reactivity is strong, solidification temperature is low, storage stability is good.At present, hydroxyalkyl amide
System the most gradually replaces polyester/TGIC becomes one of topmost outdoor powder coating systems.But its unsatisfactory weatherability,
The drawbacks such as stronger xanthochromia and pore have impact on the further development of polyester/HAA system the most greatly.
Graphene is referred to as " dark fund ", as " king of new material " of 21 century, adds in powdery paints, can be very big
Improving weatherability and the anti-yellowing property of powdery paints, exploitation can meet what the application of outdoor weathe resistance field of coating required further
Outdoor weathe resistance powdery paints is market trend.
Summary of the invention
For solving above-mentioned technical problem, the invention provides a kind of outdoor weathe resistance powdery paints, it is by following quality hundred
The component of proportion by subtraction is made:
Polyester resin 56%-65%,
Hydroxy alkyl amide curing agents 3%-3.4%,
Smooth degasifier 1%-1.5%,
Levelling agent 1%-1.5%,
Color stuffing 26.6%-38.5%,
Graphene 0.5%-2%.
It is preferred that described polyester resin acid number is 28-32mgKOH/g.
It is preferred that described Graphene particle diameter is 2.5 μm-10 μm.
It is preferred that described smooth degasifier is synthesis microwax.
It is preferred that described levelling agent is acrylate copolymer.
The method have the advantages that
The described powdery paints that the present invention provides has weatherability and the anti-yellowing property of excellence, can be widely applied to open air
The outdoor facilities applications such as building materials, square building, engineering machinery；Meanwhile, powdery paints of the present invention use safety, low toxicity β-
Hydroxyalkyl amide, as firming agent, therefore has the features such as safe and environment-friendly.
Certainly, the arbitrary product implementing the present invention it is not absolutely required to reach all the above advantage simultaneously.
