Abstract
The present invention relates to a kind of radiator graphene powder coating and its preparation technology, the coating has following component：Phenol aldehyde modified epoxy resin, hydroxyl saturated polyester resin, curing accelerator, rutile titanium oxide, butyl polyacrylate, anti-yellowing styrax, polysiloxane defoaming agent, crosslinking agent, amination graphene, carboxylated nanometer polytetrafluoroethylcomposite and rilanit special.Hydroxyl saturated polyester resin in powdery paints of the invention can make coating ensure optimal levelling while curing rate slows down；Graphene and being used in combination for polytetrafluoroethylene (PTFE) may be such that film integrally has preferable hardness, wear-resisting and lubricant effect, it is adaptable to which the surface coating of radiator class household electrical appliances, weatherability and anti-yellowing property are preferable；Film color and luster under 195 DEG C of 205 DEG C of conditions of cure does not change, after solidification under the high-temperature work environment of radiator permanent non yellowing, salt fog resistance, gloss retention and shock resistance be good, suitable further genralrlization application.
Description
Technical field
The present invention relates to the formula design field of Powder coating for radiator and preparation process of powder coating, radiated more specifically to one kind
Device graphene powder coating and its preparation technology.
Background technology
Heat radiation coating is that one kind can improve body surface radiating efficiency, reduces the sapecial coating of system temperature.Powdery paints
Be it is a kind of gradually rise in recent years it is new without the solid powdery coating of solvent 100%, with high usage, easy application, resistance to
The advantages of corrosion and environmental protection, it is widely applied in modern times spraying and anti-corrosion field of radiating, heat radiating type powdery paints is applied
Electrical equipment is remarkably improved on electric appliance casing or electronic device in itself or electronic device radiating efficiency.Radiator is a kind of standing
Household electrical appliance, need for a long time under the high temperature when being used because of it, the easy yellowing of its surface coating, tarnish, mechanical performance becomes
Difference, this not only hinders attractive in appearance, and easily shortens the safe operating life of hardware.The common feature of existing radiator is：
Solder joint is more, weld seam is long, connecting portion is more and electrostatic spraying dead angle is more, and common decoration powdery paints is in the application to radiator
During bubble, shrinkage cavity, pin hole, hardness of film difference occurs and the defect such as surface tangerine peel is big, finishing requirements can not be met.
Epoxy resin is one of very important thermoset macromolecule material, high with adhesion strength, and electrical insulation capability is good,
Shrinkage factor is low, the advantages of good processability, is widely used in the fields such as electronics, machinery, building.Graphene is as one kind by sp2
The dimensional thinlayer material of the carbon atom composition of hydridization, with excellent mechanics and thermodynamic property, can significantly increase material whole
The wearability of body.In the prior art, what what spreader surface coating powdery paints was used combined epoxy resin and Graphene
Technical method is still rarely reported, and is the layer structure for not possessing similar graphite due to Graphene, it is impossible to carry out interlayer slip, so that
Can not cause that there is good compatibility between coating each component, easily cause that the overall lubricant effect of film is not good.Therefore, open
There is the overall preferable radiator Graphene powder of lubricant effect of good compatibility, film between sending out coating each component a kind of
Last coating and its preparation technology are those skilled in the art's technical problems urgently to be resolved hurrily.
The content of the invention
