Description
Technical field
The present invention relates to a kind of preparation methods of water soluble acrylic acid amino baking carbon black paint, belong to macromolecular organic compound
Synthesis technical field.
Technical background
Water paint advantage: first, with water as solvent, saves vast resources；Fire risk when eliminating construction；It reduces
To atmosphere pollution；Only with a small amount of hypotoxicity alcohol ethers organic solvent, operating environmental condition is improved.General water paint has
Between 15%~15%, the second water paint can be coated directly in wet structure and wet environment and be applied solvent (accounting for coating)
Work；Good to material surface adaptability, coating adhesion is strong.Third coating tool can wash by water, and greatly reduce cleaning solvent
Consumption.So the dosage of water paint is increasing, wherein the most outstanding is water soluble acrylic acid amino-stoving varnish, dosage is increasingly
Greatly, it is mainly used for coating coiled material, metal bucket, electric vehicle, motorcycle, automobile, mechanical equipment, stainless steel door, aluminium alloy door and window, steel
Structure component etc..
After frequently encountering baking when preparing aqueous carbon black baking vanish at present, surface of the paint film transparency is bad, and blackness is inadequate, aqueous
Carbon black slurry additional amount wants phenomena such as big, this is because the high bp polar solvent ethylene glycol monobutyl ether contained in aqueous carbon black baking vanish
Isopolarity is not strong enough, and the polarity of black carbon surface is very strong, and dissolubility is bad in these high boiling solvents, and the paint sprayed is toasting
In the process, when last these polar solvents volatilization, most of carbon black can not be taken to surface of the paint film.So will be in aqueous carbon black
The very strong solvent of polarity is added in baking vanish: ethylene glycol, propylene glycol, diethylene glycol monomethyl ether etc., carbon black dissolves in these solvents
Performance is good, when volatilizing in baking process, most of carbon black can be taken to surface of the paint film, keep carbon black arranged distribution good, appearance effect
Fruit is good, and blackness is also enough when amount of carbon blacks adds few.
