Also, the appearance effect of the polyhedral pigment can be changed through changing the types of the composite coating layer, such that multicolor, brightening and other effects can be provided.
Description
Technical field
The present invention relates to a kind of micro-nano powder material and preparation method thereof, particularly with regard to a kind of polyhedron micro-nano powder material
Material and preparation method thereof.
Background technology
Along with society development, it is more and more higher that product appearance is required by people, have pearly-lustre, flash effect particular color get over
More come to be favored by people.The traditional solution of particular color is to use spraying coating process, but spray process on the one hand work
Sequence is complicated, becomes to produce cost high；On the other hand environmental pollution is easily produced during spray process.Therefore, the most popular
It is utilized in glazed plastic base material directly adding flap-type metallic pigments, mica titanium nacreous material etc. and there is particular color pigment
Scheme is to replace traditional spraying scheme, and its resin prepared accordingly may be generally referred to as aesthetic resin.But due to flap-type metallic pigments,
The addition of mica titanium nacreous material so that aesthetic resin is in application process, and especially Injection moulded part, when mould inside melt material
Stream existence meet welding time, due to pigment orientation, easily produce weld bond, on product formed a dark stricture of vagina, the most molten
Wiring, strong influence product aesthetics, this is also to exempt from the huge bottleneck that spraying coating process is faced at present.
The proposition of polyhedron micro-nano powder material is based on the defects such as flap-type metallic pigments apparent flaws in application process.
Polyhedron micro-nano powder material is to plate attached one layer of metal with metal effect or other compound coating at host surface,
It is made to possess market aluminium powder on sale or the appearance of copper powder.For polyhedron micro-nano powder material is relative to flap-type structure, major diameter
Ratio is closer to 1, in plastic injection moulding process, the phenomenons such as orientation will not occur, thus do not have bright in melt junction
" weld bond " flaw shown.But polyhedron micro-nano powder material is during storing and using, owing to coating leaks the most cruelly
In air, easily contact with the oxygen in air or other corrosive gas, cause corrosion of coating, the phenomenon that powder body shades,
Directly affect polyhedron pigment self effect and using effect.Meanwhile, existing polyhedron micro-nano powder material there is also color list
First-class shortcoming, range of application suffers restraints.
For these reasons, this patent designs the polyhedron micro-nano powder material of a kind of composite film coating structure.Such composite film coating
On the one hand structure can effectively intercept coating and connect storage with oxygen or corrosive gas, extends and stores and service life.It addition, can
With the kind by regulating composite deposite, change the appearance of polyhedron pigment, as colorful, highlight.
