Description
Technical field
The present invention relates to water aluminum powder paint technical field more particularly to a kind of use the waterborne epoxy modified of oiliness aluminum paste
Acrylic resin aluminium paint and preparation method thereof.
Background technique
Metallic aluminium is active tellurium, and Yi Yushui, soda acid reacts, therefore is applied to water-base resin system
When, it is necessary to pass through special surface treatment.Currently, the preparation method of water aluminum-silver slurry in the market, substantially addition corrosion inhibitor,
Chromic acid or its salt deactivation method.Inorganic matter coated with silica method, inorganic organic matter double-coating or hydridization cladding process.These methods
Undoubtedly it is intended to aluminium and water segregation.But existing water aluminum-silver slurry in the market is because technique requires very rigorous, nature
For, price is generally higher, is 3 times of oiliness aluminium paint or more, and production technology is unskillful, causes product extremely unstable
Fixed, the package of aluminium powder is incomplete, and storage still exists in water-based system either in the form of aluminum paste, all can be with water
Contact causes reaction Al+H2O→Al(OH)3+H2↑ generation, influence the quality and performance of coating, cause damages to client.
Summary of the invention
The present invention is provided and a kind of uses oiliness aluminium to solve the stability and cost problem of aluminum paste and water-based system
Epoxy modified acrylic resin aluminium paint of silver paste and preparation method thereof.
The present invention adopts the following technical scheme that:
A kind of waterborne epoxy modified acrylic resin aluminium paint, the aluminium paint are prepared by the raw material of following weight percent
It forms:
Waterborne epoxy modified acrylic resin 30-70%, deionized water 10-30%, wetting agent 0.5-1%, pH adjusting agent
2-6%, thickener 0.5-1%, cosolvent 5-8%, amino resins 3-6%, oiliness aluminum paste 5-6%, the weight of the raw material
The sum of percentage is 100%；The cosolvent is the composition of ethylene glycol monobutyl ether and isopropanol.
Preferably, the weight percent of the raw material are as follows: waterborne epoxy modified acrylic resin 50%, deionized water
27.9%, wetting agent 0.8%, pH adjusting agent 3%, thickener 0.8%, cosolvent 8%, amino resins 4.5%, oiliness aluminum paste
5%.
The waterborne epoxy modified acrylic resin is provided by Changzhou Guang Shu Chemical Industry Science Co., Ltd, model
GS-355 or GS-330.
The wetting agent is ammonium polyacrylate salt, polycarboxylic acids ammonium salt, polycarboxylate sodium, polyethers phosphate, modified polyether
One or more of combination.Preferably, the wetting agent is the TEGO Dispers 655 of TEGO company.
The pH adjusting agent be AMP-95, N, one or more of N- dimethylethanolamine, triethanolamine
Combination.
The thickener is polyurethane associative thickener, in alkali-swelling type thickener, organobentonite thickener
A combination of one or more.
The cosolvent is the composition of the mass ratio 1:3 of ethylene glycol monobutyl ether and isopropanol.
The amino resins is part Amino resin, in full Amino resin, high imino group resin
It is one or two kinds of.
The oiliness aluminum paste is the kind generally sold in market, and general there are also a small amount of high boiling organic solvents.
The present invention also provides the preparation methods of above-mentioned waterborne epoxy modified acrylic resin aluminium paint, including walk as follows
It is rapid:
2/3 isopropanol is put into container, is stirred with 200r/min, oiliness aluminum paste is then added, stirs 2-3min,
30min is stood, upper layer mixed liquor is isolated, 1/3 isopropanol is added again, stirs evenly, it is spare；Obtain mixture A；
Amino resins is uniformly mixed with ethylene glycol monobutyl ether spare.Obtain mixture B；
Waterborne epoxy modified acrylic resin is added in paint mixing tank, low whipping speed is the condition of 200-300r/min
Under, pH adjusting agent is added, after stirring 2-3min, wetting agent is added, stirs 2-3min, deionized water is added, stirs 10-20min；
Mixture A is added in paint mixing tank, with the mixing speed of 200-300r/min, stirs 20-30min, it is rear slow
Mixture B is added, continues to stir 10-20min, thickener is slowly added in paint mixing tank, finally continues to stir 10-20min, mistake
Filter is packed to get finished product.
Waterborne epoxy modified acrylic resin aluminium paint of the invention, select first be cheap, production technology
Through very mature oiliness aluminum paste, oiliness aluminum paste forms aluminum paste shape using high boiling organic solvent dissolution (not soluble in water)
State, completely isolated water and air.In the form of supply of material with regard to more stable, water prescription is before use, first with isopropanol oiliness aluminium
Silver paste dissolution, in oiliness aluminum paste mineral oil and high-flash aromatics simply extract, isolate upper layer mixed liquor, so
After a kind of wetting agent is added, be a kind of modified polyether containing high pigment affinity groups, provided by TEGO, model TEGO
Dispers 655, in fact, being the polymer that a kind of pair of aluminium powder has package action, structural formula are as follows:
It is to be esterified by styrene oxide, polyethers with the polymer with phosphate radical structure, and phosphate radical ionizes out H+,
Make polymer in acidity, to react with aluminium, complicated metal complex is formed on the surface of aluminium, in the form of passivation layer
Completely cut off the water in aluminium and coating system, so that coating be made to maintain storage stability.
Waterborne epoxy modified acrylic resin (GS-355 or GS-330) the collection water-based acrylic resin that the present invention uses is excellent
Different cohesiveness, weatherability, film forming protect light colour retention and the excellent adhesion of aqueous epoxy resins, anticorrosive property, chemically-resistant
The advantages that moral character, thermal stability, is a kind of very high resin of comprehensive performance, can meet wanting for client in all its bearings
It asks.
