Description

A kind of preparation method of multi-usage iron oxide red aqueous color paste
Technical field
The present invention relates to a kind of preparation method of iron oxide red aqueous color paste, relate in particular to a kind of multi-usage, economy, high performance iron oxide red aqueous color paste.
Background technology
Aqueous color paste is coloured material, and its Application Areas is very wide, comprises the industries such as coating, leather, ink, paper, latex, weaving.It is painted that the water-based iron oxide color paste of producing is at present used for greatly building coating emulsion paint, as application number 03102844.6,03132933.0,03106999.1 and 200510120763.0 all belongs to this class mill base, its composition is mainly dispersion agent, defoamer, iron oxide pigment, sanitas, thickening material and water, there is good consistency with emulsion paint, its dispersion agent adopts polyacrylic acid sodium salt or ammonium salt class mostly, this class mill base is stored (about 2 months) poor stability for a long time, point water is serious, hard-caked sediment; Adopt polyacrylic acid sodium salt or ammonium salt class to make dispersion agent, iron oxide pigment is had to higher choosing, its cost will improve 40% left and right, and economy is not comparable.And this class mill base is not suitable for water-borne wood coating, aqueous automobile paint, water-based paper coating, water-based plastic coating, aqueous glass paint etc., there is the coating disadvantages such as consistency is bad, floating.At water-borne wood coating, aqueous automobile paint, water-based paper coating, water-based plastic coating, aqueous glass paint, the performance to mill base, environmental protection standard require more and more higher at present, meet this type of mill base requirement and will select high performance dispersion agent, as BYK190, TEGO750W etc., its cost performance does not meet the market requirement.Therefore develop a kind of high-performance, economy, the feature of environmental protection, meet the applicable mill base of all water-borne coatingss and be even more important.
Summary of the invention
The present invention selects the pigment affinity groups that contains ammonium salt and the polymeric dispersant with negatively charged ion, nonionic feature of hydrophilic radical, this base polymer has A-B-A block polymer structures, having good dispersion stabilization, the feature of environmental protection, is the incomparable property of conventional surfactants.Its molecular structure can be pectination, can be again higly branched chain, thereby to disperse particles surface coverage and seal effect and be better than conventional surfactants far away, its dispersion system more tends towards stability, flows.Therefore the mill base of making has the features such as package stability is good, tinting strength is high, consistency is good.
This dispersion agent is that amphiphilic polymer has higher molecular weight, and its aqueous solution has high viscosity, utilizes the high viscosity of its aqueous solution itself, can improve the viscosity of other water-based system, thereby amphiphilic polymer has thickening function, can play system thickening result of prevention.
This dispersion agent preparation is simple, and raw material is easy to get, and cost is close with polypropylene-base dispersion agent, be the dispersion agent that a kind of cost performance is high, and consumption is few, and the iron oxide red aqueous color paste making has high-performance, economy, the feature of environmental protection, meets all water-based system coating and uses.
In order to solve technical problem recited above, the present invention takes following technical scheme: the present invention relates to a kind of multi-usage iron oxide red aqueous color paste, its basic recipe is: water 10%~25%, wetting Agent for Printing Inks 3%~10%, wetting agent 1.5%~3%, dispersion agent 3%~7%, AMP-95 auxiliary agent 0.3%~0.6%, ferric oxide red powder 40%~70%, thickening anti-settling agent 0.3%~1.0%, sterilant 0.1%~0.3%, defoamer 0.1%~0.5%.
Wherein, wetting Agent for Printing Inks is selected the one of propylene glycol, Macrogol 200, Liquid Macrogol.
Wetting agent is selected alkyl polyoxyethylene ether solution.
Dispersion agent is selected the pigment affinity groups and the polymeric dispersant of hydrophilic radical, preferably the maleic anhydride styrylamine salt copolymer solution that contain ammonium salt.
Thickening anti-settling agent is selected one or more the combination of modified alta-mud, urethane, aluminum magnesium silicate, aerosil and HEC.
The present invention proposes a kind of preparation method of multi-usage iron oxide red aqueous color paste, preparation technology is as follows: add deionized water by formulation weight ratio, wetting Agent for Printing Inks, wetting agent, dispersion agent, PH conditioning agent, speed with 500r/min in high speed dispersor stirs, then under the high speed of 1000~1200r/min, add ferric oxide red powder, high speed dispersion 45min, grind again 3-4 all over until fineness qualified after, under 800~1000r/min, add thickening anti-settling agent to stir 15~20min, evenly without particle, under low speed, add sterilization, defoamer, after viscosity fineness is qualified, filter and package and obtain iron oxide red aqueous color paste.
The feature such as iron oxide red aqueous color paste package stability that the present invention makes is good, tinting strength is high, consistency is good, has high-performance, economy, the feature of environmental protection, is a kind of high performance-price ratio multi-usage iron oxide red aqueous color paste.Be widely used in aqueous architectural coating, water-borne wood coating, aqueous automobile paint, water-based paper coating, water-based plastic coating, aqueous glass paint, water-based leather coating and water color ink etc. painted.
