Description
Technical field
The invention belongs to technical field of fine, in particular it relates to a kind of water-based organic pigment mill base and its
Preparation method, mill base of the present invention are the environment-friendly type mill base with high-compatibility.
Background technology
With the development of society and the enhancing of environmental consciousness, the trend of coating Water-borne modification increasingly strengthens, and color is more
Sample is also the demand of modern social development, and therefore, the use of aqueous color paste is more and more frequent.Aqueous color paste is used in coating
It is more more convenient than using toner toning in production process to be mixed colours, and has the advantage that：(1) environmental protection and economy：Toning process
In do not have dust, and a large amount of clouts will not be produced；(2) it is easy to operate：Aqueous color paste add in coating only need to mix it is several
Minute, without prolonged scattered or grinding；(3) rich in color, colour gamut is broader, several mill bases arbitrarily arrange in pairs or groups can tune
Allot different colors.
Aqueous color paste and water paint are all stable dispersions, if the two different stable dispersion systems are mixed
Together but poor compatibility, it will there are many adverse consequences, for example, the accuracy of toning and uniformity it is poor；Color is not after toning
Bright-coloured, saturation degree is low, and mill base addition is big, increases cost；Flocculate, lump in colored paint placement process, return thick, thickening；Apply
Occurs floating when work, it will be apparent that the bad paint film effect such as joint print；Weatherability, the water resistance of paint film reduce, easily
Fade, efflorescence.
Therefore, the compatibility of aqueous color paste and water paint is even more important.Influence compatibility of the mill base in emulsion paint
Factor is a lot, including the species of wetting dispersing agent and dosage, the surface treatment method of color stuffing, the species and dosage of thickener.
And the stability of aqueous color paste relies primarily on electrostatic repulsion and steric hindrance effect in system, when both effect disequilibriums
When, phenomena such as layering divides water, flocculation, precipitation will occurring in aqueous color paste during storage, have a strong impact on the use of mill base.
The dosage that generally use changes wetting dispersing agent solves the compatibility of mill base and coating, but this method has limitation,
And the dosage of wetting dispersing agent is more, cost is not only increased, but also the water resistance of paint film can be influenceed, influences making for coating
Use effect.
Therefore, there is an urgent need to develop the aqueous color paste and its system that a kind of compatibility is good, environmentally friendly, using effect is good for this area
