Summary of the invention
The object of this invention is to provide organic mill base of a kind of water-based and preparation method thereof, product is used for the toning of latex coating, while retaining the advantage such as bright-coloured, strong coloring force of original organic mill base, improve the stability in storage of organic mill base, weathering resistance, and have good in latex coating intermiscibility.
To achieve these goals, the technical solution used in the present invention is as follows:
The organic mill base of a kind of water-based, for the toning of latex coating, comprise following component and mass percent thereof: antifreeze hydrophilizing agent 8% ~ 10%, wetting dispersing agent 8% ~ 10%, defoamer 1% ~ 2%, sterilant 0.1% ~ 0.3%, anti-settling agent 0.5% ~ 3%, pigment dyestuff 30% ~ 40%, surplus is pure water.
According to above scheme, described antifreeze hydrophilizing agent is propylene glycol.
According to above scheme, described wetting dispersing agent is nonionic surface active agent.
According to above scheme, described defoamer is organic-silicon-modified mineral oil antifoam agent.
According to above scheme, described sterilant is 1,2 benzisothiazole base-3 (2H)-one sterilant.
According to above scheme, described anti-settling agent is fumed silica auxiliary agent.
According to above scheme, described pigment dyestuff is azo pigment, polycyclic pigment, phthalocyanine pigment etc.
A preparation method for the organic mill base of water-based, comprises the steps:
1) antifreeze hydrophilizing agent and wetting dispersing agent are mixed;
2) by the antifreeze hydrophilizing agent after pure water, mixing and wetting dispersing agent, add in premix a mixing bowl, stir 3 ~ 5 minutes;
3) add defoamer, sterilant, anti-settling agent stir 3 ~ 5 minutes;
4) add pigment dyestuff to stir 10 ~ 15 minutes, obtain Preblend;
5) Preblend is carried out grinding 8 hours, to fineness≤40um, Δ E≤0.8, Δ L≤0.8, Δ a≤0.8, Δ b≤0.8, relative color strength %=100 ± 5, get product.
According to above scheme, the shredder of described grinding is the circulating horizontal mill of single cylinder.
The invention has the beneficial effects as follows:
(1) wetting dispersing agent of the present invention is nonionic surface active agent, and this wetting dispersing agent is particularly useful for the pigment dyestuff of difficult dispersion, and can prevent from returning slightly;
(2) anti-settling agent of the present invention is fumed silica auxiliary agent, and there is silanol on surface.Through abundant dispersed with stirring, between silanol, form hydrogen bond, produce tridimensional network, increase the viscosity of dispersion system, produce thixotropic flow performance thus play the effect preventing sedimentation;
(3) antifreeze hydrophilic additive of the present invention, is conducive to the intermiscibility of this organic mill base and emulsion paint;
(4) organic mill base that preparation method of the present invention obtains substantially increases its stability in storage and weathering resistance.
