Description
Technical field
The present invention relates to aluminium powder pigment technical field, particularly relate to a kind of cyanuric acid lanthanum modified manometer silicon dioxide cladding and change
Property thin slice aluminium powder pigment and preparation method thereof.
Background technology
Thin slice (0.1~1 μ m-thick, 5~50 μm length or width) metallic aluminium pigment is owing to having special changeable colors along with angle optics effect
Should and metallic luster, be widely used in car paint, industrial coating, printing-ink and plastics and add
In industry.But aluminum is amphiprotic activity metal, the O in contact acid aqueous slkali or air2As easy as rolling off a log generation aoxidizes and becomes
Black, affect its metallic luster, also can produce substantial amounts of H2, affect its bin stability.
Improving the bin stability of aluminium powder, prevent aluminium powder surface oxidized, effective method is to enter at aluminium powder microparticle surfaces
Row modification, one layer of corrosion inhibitor of surface adsorption or one layer of inert layer of microcapsule coated, isolation aluminum and oxygen, directly the connecing of water
Touch.Compared to absorption organic corrosion inhibitor, form one layer of thin and compact passivation layers of chrome or SiO on aluminium powder surface2Layer
Deng inorganic layer, there is extraordinary oxidation and corrosion performance .Y .Iriyama with tetraethyl orthosilicate (TEOS) as forerunner
Body, using plasma polymerization has been coated with one layer of SiO at aluminium powder particle surface2 Layer.Sol-gal process because reaction temperature is low,
Processes and apparatus is simple, has wider industrial application value.Ralf Supplit and Ul rich Schubert uses phosphorus
Acid catalysis teos hydrolysis carries out ground floor cladding to aluminium powder, then with hexadecyl trimethoxy silane or dimethyl two
Methoxy silane hydrolysis carries out second layer cladding, and cladding aluminium powder has preferable stability in the alkali liquor of hot water and pH=9.
Liu Hui etc. use methyl allyl acyloxypropyl trimethoxysilane that aluminium powder carries out pretreatment, then use emulsion in situ to gather
The method cladding polymethyl methacrylate closed.Li Lijuns etc. use TEOS that thin slice aluminium powder has been carried out Nano-meter SiO_22Cladding,
TEOS and VTES is used to hydrolyze simultaneously and aluminium powder has carried out the Nano-meter SiO_2 of hydridization2 Cladding, and at this base
Using polymer to carry out second layer cladding on plinth, cladding aluminium powder can stable existence 30 d in the alkali liquor of pH=11.Jo
Stein Mardalen etc. find that the impact of the chemical stability of cladding aluminium powder is compared coated Si by the form of coated Si and coverage degree
The impact of thickness more important.
" Nano-meter SiO_22Coating modification thin slice aluminium powder pigment and acid resistance research thereof " literary composition with TEOS as presoma, adopt
SiO is prepared by sol-gel process2Aluminium powder pigment (the Al/SiO of cladding2), detailed examination reaction temperature, response time, aluminum silicon
Than process conditions such as (S=nAl/nTEOS), water silicon ratio (R=nH2O/nTEOS) and catalyst amounts to clad form and product
The acid proof impact of product.
But use Nano-meter SiO_22The thin slice aluminium powder pigment brightness of coating modification declines, and needs to improve.And aluminium powder pigment
Corrosion resistance, thermostability, anti-radiation, ultra-violet resistance, resistance to water, resistance to ag(e)ing, antibiotic property, corrosion resistance, scratch,
The performance such as stability, thermal diffusivity is also required to further promote.
