Description
Technical field
The present invention relates to water aluminum-silver slurry fields, particularly, are related to a kind of water aluminum-silver slurry with clad.In addition,
The invention further relates to a kind of preparation methods including the above-mentioned water aluminum-silver slurry with clad.
Background technique
Aluminum paste (aluminium powder) is important one of metallic pigments, because it has high bright metallic luster in coating work
It is used widely in industry, printing ink and plastics industry.Currently, the domestic annual volume of production and marketing of aluminum paste is probably on 50,000 tons of left sides
The right side, wherein external import and its 8000 tons of product.
For a long time, in terms of coating, aluminum paste is applied in solvent-based system always.In recent years, with coatings industry
Further development and the enhancing of people's environmental consciousness, the regulation that toxic solvent is discharged in opposite atmospheric environment is increasingly stringent,
Low pollution, nuisanceless, non-dusting coating products production development paid much attention to.Organic solvent, aqueous painting are replaced with water
Material has become the inexorable trend of coating industry development.Since country's in June, 2015 issues " volatile organic matter Pollution Charges Site
Method ", it is specified that starting to impose VOC charges for disposing pollutants, the policy of national and local governments control atmosphere pollution on October 1st, 2015
Formal landing, water aluminum-silver slurry is trend of the times.American-European countries has all formulated corresponding ring to strictly limit VOC emission amount
Regulation is protected, coating is promoted to develop to the direction of high solid, Water-borne modification, powdered.It is had reached it is reported that applying Water-borne modification in Europe
38% or more, finishing coat Water-borne modification has reached 57%.The producer of domestic application water paint is also more and more.Aluminum paste is that coating dodges
The source of light effect will reach good decorative effect, it is necessary to use aluminum paste.Furniture industry, car paint, ink industry,
Hardware household electric appliances largely begin to use the aluminium pigment that can be used for the water aluminum-silver slurry of water paint.
Since aluminum paste can be with water reaction, 2Al+6H in the environment of water2O→2Al(OH)3+3H2Generate H2, i.e., so-called
The problem of " getting angry " leads to various aspects.Current water aluminum-silver slurry so-called on the market is in traditional oiliness aluminum paste carry out table
Face modification prepares water aluminum-silver slurry.There are mainly two types of, physical protection method and chemoproection method.
Physical protection method is the resin in aluminium powder surface package layer of transparent as protective layer.Such as using in-situ polymerization in aluminium
Powder surface coats polystyrene resin layer, but need to know that the cohesive force of polystyrene and aluminium powder is very weak, and resin is under high shear forces
It is easy to fall off from aluminium powder surface, loses the protective effect to aluminium powder.And aluminium powder partial size is bigger, using aluminium powder as parent original position
Polymerized monomer conversion ratio and resin clad ratio all will not be too high.Anti- high-pressure conductive is also poor.Application number 200810207593.3,
It is coated using epoxy phosphate ester resin, phosphate has very strong anchoring to act on aluminium powder, and adsorption capacity is strong, solves and aluminium
The adhesion problem of powder, but matrix used is epoxy, and the weather resistance of epoxy all exists much with the compatibility of water paint base-material
The problem of, and molecular weight of epoxy resin is lower, prevents the ability of the diffusion of hydrone weaker, increases the corrosion to aluminum paste.
Chemoproection method mainly has two class of additive technology and coating technology.It is organic phosphorus that additive technology mainly passes through addition
Compound, such as the Stapa series of Eckart, (Eckart, Siberline are the world two to the AquasilBP/AN of Siberline
Big aluminium powder supplier), but due to addition be small molecule compound, it is difficult really to protect the stability of aluminium powder in water.Separately
One side effect is possible to influence whether the performance (such as drying time, adhesive force, moisture-proof) of coating.Technique for packing also experienced
Two generations.The first generation is using insoluble chromium compound (such as EckartHydrolux) and presently preferred prevents aluminium powder point rotten
The representative of corrosion energy, but with the enhancing of environmental consciousness, chromate is gradually eliminated due to its carcinogenic toxicity.The second generation is then
Now more popular SiO2Cladding, some is even in SiO2Organic matter modification is further added by the basis of cladding to improve and paint-based
Compatibility, raising adhesive force of material etc., the aluminium powder processing technique of such as Japanese Japan, the Hydrolan series of Eckart, but it is such
SiO2Coating technology is to increase SiO on the basis of original aluminium powder2Clad come achieve the effect that protect aluminium powder, although preventing from sending out
Gas, wet-heat resisting, weather-proof and cycle performance of resistance to pipeline etc. reach very excellent comprehensive performance, but SiO2Clad certainly will influence whether
Original brightness of aluminium powder and sudden strain of a muscle degree also easily cause the reunion of aluminium powder in treatment process, and manufacturing cost is also very expensive, market
Difficulty.
In conclusion current technology developing water is average respectively there are advantage and disadvantage, and all have the characteristics that one, is preparing coating
Before, aluminum paste producer needs to carry out oiliness aluminum paste cumbersome process, and the aluminium silver that can be used for water paint could be made
Slurry.

The main component of aluminum paste is aluminium flake, can be in the preparation method of the water aluminum-silver slurry covering material of the application
Common oiliness aluminum paste or water aluminum-silver slurry are raw material.
The polymerization reactant that the present invention selects is reactive acroleic acid.The reactive acroleic acid is that molecule amount differs
Acrylate homopolymer or copolymer, the surface tension of this substance only slight decrease coating, can balance surface of the paint film tension difference
It is different, obtain the surface of the paint film of really smooth, similar mirror surface.
Carrying out polymer modification to meso-porous titanium dioxide silicon face, there are mainly three types of methods: physical absorption, polymer grafting
(graft to) and surface initiation polymerization (graft from).Wherein physisorphtion preparation method is simple, but obtains miscellaneous
Change material since without chemical bond, polymer is easy to fall off between the two.The preparation method of graft to and graft from
It is relative complex, but there is covalent bond effect, high stability, therefore use is more wide between mesoporous silicon oxide and polymer
It is general.The difference of the two is: graft to is to be connected to meso-porous titanium dioxide silicon face using the active group of existing polymer；
Graft from then utilizes the initiation point of mesoporous silicon oxide surface modification directly to cause monomer polymerization.
The present invention provides the water aluminum-silver slurry with clad using graft to method preparation another aspect of the present invention
Preparation method, the present invention in active group trimethoxy silane be initiator itself carry, when Macroscopic single crystal just
The step of introducing, polymer secondary modification be omitted.
