Abstract
The invention relates to coating compositions comprising at least one solvent-containing binder, an aqueous universal pigment preparation and, if appropriate, auxiliaries and additives and their use as paints, varnishes, adhesives or printing inks.
Description
Technical field
The present invention relates to contain solvent cement, waterborne general pigment preparation by at least a, and the coating composition of auxiliary agent optionally and additive.
Background technology
Coating composition can be used as colorant (Farbe), paint vehicle (Lack), tackiness agent, printing ink or printing-ink, is used to apply the object that is for example prepared by metal or plastics.Described coating composition is applicable to all conventional applying methods that adopt in modern washing and plastic coat and the printing-ink industry, the printing of for example spraying, electrostatic spraying and the various printing processes of employing.
Typically by preparing pigment preparation earlier, then the mode with former lacquer (Stammlack) coating (auflacken) prepares Color paint.
In liquid medium, disperse filler and pigment during the preparation pigment preparation.This adopts dispersion agent to implement usually, thereby makes solid effectively disperse the mechanical shear stress of needs with reduction, realizes high as far as possible fill level simultaneously.Dispersion agent has promoted the decomposition of aggregate, and surface wetting as surface active cpd and/or that dispersed particle is treated in covering, makes these particle-stabilisedization to avoid disadvantageous reagglomeration.
In the production of colorant and paint vehicle, wetting agent and dispersion agent have promoted the introducing of pigment and filler, and it has determined the visual appearance and the physicochemical property of coating substantially as important recipe ingredient.For realizing its best applications, these solids must be dispersed in paint vehicle and the colorant on the one hand, in case dispersed obtains then must be stable on the other hand.In many cases, the function of stabilization component also can realize by binder ingredients.Because this class tackiness agent is to the contribution of faster drying and the increase of film former hardness, they also are the important component of coating.
For solvent-laden coating, serve as the solvent-laden pigment preparation of basis preparation with various wetting agents and dispersion agent usually, itself and the various former lacquer of solvent that contains apply.For water-borne coatings, serve as basis preparation aqueous pigment preparations also usually with various wetting agents and dispersion agent, it applies with the former lacquer of different water-baseds.
For fear of owing to preparing and storing expensive that a large amount of pigment preparations cause, obtain general pigment preparation and expect.
Comprise for the important parameter of in universal pigment preparation, using, at first, with the general consistency of other tackiness agent, for example with the consistency of important long oil alkyd, vegetables oil, hydrocarbon resin, acrylate resin and polymeric amide; Secondly, the general solvability in organic solvent, for example based on environmentalism and toxicology viewpoint adopt usually at petroleum solvent and pure aliphatic cpd.Have general consistency and deliquescent tackiness agent that this class can be used in the pigment preparation for example are recorded among the DE 4404809.
Dispersion agent as universal pigment preparation uses ethoxylated alkylphenol or alkoxy fatty alcohols especially, and it helps the spatial stability of the pigment dispersion phase that obtained.A large amount of criticisms of adopting ethoxylated alkylphenol to be subjected to the environmental toxicology aspect.Its application in washing composition and cleaning product is under an embargo in many countries.Paint and printing ink industry are estimated also similar ban can occur.Alkoxy fatty alcohols can not obtain and the same good pigment wettability of ethoxylated alkylphenol in many cases owing to lack adsorption group.The not absorbed portion of these product types has extra detrimental action for foam stabilization especially in aqueous pigment preparations.
The polyalkylene oxide of block copolymerization is no problem on toxicology, and has high absorbability, but has lower foam stabilizing action.It for example is recorded among the EP 1078946.Yet these products can not obtain foam inhibition completely.Therefore, must add active froth breaking material in hydrotropisms's pigment preparation at this.But these materials have other adverse side effect, for example unfavorable surface imperfection.Because its disadvantageous effect for water-resistant coating and light stability, many dispersing additives can not use.
PCT/EP2006/050437 has described the pigment preparation based on the polyalkylene oxide that contains Styrene oxide 98min. of block copolymerization and ketone-urea formaldehyde combination, it has the extensive consistency with the tackiness agent that uses, with in organic solvent that uses and the solvability in the water, foamy forms and is suppressed in aqueous pigment preparations.Be very suitable for producing the solvent that contains coatings volatile organic compounds and use suitable for example ethylene glycol if this class contains the solvent pigment preparation, also be suitable for producing water-borne coatings.In addition, PCT/EP2006/050437 has described aqueous pigment preparations and has possessed application in the water-based coating of outstanding performance in production.
