Description
Technical field
The invention belongs to paint fields, and in particular to a kind of heat-resisting phosphatization powdery paints and preparation method thereof.
Background technique
Powdery paints is a kind of novel without 100% solid powdery coating of solvent.With without solvent, pollution-free, section
It saves the energy and resource, reduce labor intensity the features such as high with coating machinery intensity.It has three categories: thermoplastic powder coating
(PE), thermosetting powder coating, building powder paint.Coating is by specialty resins, pigments and fillers, curing agent and other auxiliary agents, with one
Fixed ratio mixing, then be prepared by hot extrusion and the techniques such as pulverize and sieve.They store and stablize, through quiet at normal temperature
Electrospray, friction spraying (heat curing process) or fluidized bed dipping (thermoplastic method) reheat baking melting and solidification, make to be formed smooth
Bright permanent film reaches decoration and etch-proof purpose.Its characteristic has: 1, the product is free of toxicity, without solvent and
Without the virose substance that volatilizees, therefore the problem of the public hazards such as discharge without poisoning, without fire, without " three wastes ", country is complied fully with
The requirement of environmental law.2, utilization rate of raw materials is high, and the powder of the powder supplies quotient production of some famous brand names crosses the powder of spray
Recoverable, highest utilization rate even can be up to 99% or more.3, after coated article pre-treatment, one-off construction is not necessarily to primary coat,
The film of adequate thickness, Yi Shixian automatic operation can be obtained, high production efficiency can reduce cost.4, coating is fine and close, adheres to
Power, impact strength and toughness are good, and corner coverage is high, have excellent resistance to corrosive chemicals energy and electric insulating quality
Energy.5, powdery paints storage, transportation safety and conveniently；
However as society development, requirement of the people for coating is also higher and higher, for traditional powder coating intensity and
Stability etc. made higher requirement, especially different geographical, because of the difference of environment, the requirement for powdery paints is also answered
This is that different, of the invention coating is for the higher area of temperature, it is therefore an objective to improve the heat-resistant stability of coating.
