Description
Technical field
The present invention relates to technical field of fine, be specifically related to a kind of production line toning polymer overmold inorganic pigment color paste and preparation method thereof.
Background technology
Coating production line toning integral system is a kind of novel tinting system, and it is by toning software control colour mixer, and mill base is directly injected barreled coating by cubing mode, then through capping, concussion, realizes coating automatic color regulating.Mineral dye has sun-proof, heat-resisting, weathering resistance, solvent resistance are good, the feature of strong covering power for cobalt blue, ferric oxide, carbon black etc., is the pigment variety of coating industry large usage quantity, is also the main inorganic colorant material of coating production line toning integral system.Because the grain diameter of mineral dye and density are large, dispersing auxiliary is not easily adsorbed in surface, easily there is the phenomenons such as granules of pigments particle diameter becomes large, sedimentation in the aqueous color paste that therefore mineral dye is made, cause tinting strength significantly to reduce in storage process.And once mill base tinting strength reduces, then colour mixer must be caused to mix colours and occur deviation, cause client returns, even coating is scrapped.
The rigors that inorganic pigment color paste prepared by general technology there will not be sedimentation after being difficult to meet production line toning use mill base long-time storage, tinting strength reduces, therefore, the inorganic pigment color paste that Preparation and storage stability is high be production line mix colours integrated tinting material produce gordian technique.In recent years, more about the research preparing production line toning nano dye mill base, but the Basic practice preparing mill base is all attrition process under dispersion agent is assisted.Such as, publication number is that the Chinese patent of CN1986660 discloses the method with high polymer dispersant being prepared by mineral dye dispersion to water-base inorganic pigment color paste; Publication number is that the Chinese patent of CN101760085 discloses the method adopting dispersion agent directly to be prepared by mineral dye processing to inner-outer wall emulsion paint toning inorganic pigment color paste; The patent No. is the method that the United States Patent (USP) of US6489393 and US7268180 then discloses the pigment such as titanium white, mica and prepares mill base, the pigment component that it adopts except containing except oxide compound, not through other modification.But the phenomenon such as pigment sedimentation, tinting strength reduction that dispersion agent desorption causes often can occur mill base prepared by these techniques in long-time storage process, be difficult to use in production line toning.
Dispersion agent is adopted directly to disperse mineral dye, there is dispersion agent little at surface of pigments adsorption, the defects such as desorption phenomenon is serious, after long-time storage, very easily because pigment agglomerates, pigment particles particle diameter becomes and causes greatly degradation problem under the tinting strength of inorganic pigment color paste in mill base, and when dispersant concentration is higher, dispersion viscosity can be caused excessive, easy to foaming, so also can reduce production line toning accuracy and circulation ratio, cause produce coating occur batch difference.
