Abstract

Composite compounds of co-structured or co-adsorbed organic or mineral fillers or pigments containing at least two organic or mineral fillers or pigments of a different nature and the use thereof in the paper industry for manufacturing paper, filling or coating or for any other surface treatment of the paper as well as wood or metal or plastic or cement surface treatment compounds in the fields of aqueous and non-aqueous paints and plastics materials. Coatings colors, uncoated filling compound and sheets of base paper for coating containing them.

Claims (9)

1. A method of manufacturing of aqueous suspensions of organic or mineral pigments or fillers, paper coating colors and/or paper filing or paper surface treating material, comprising:

preparing said materials aqueous suspensions from a composite compound of mineral or organic fillers or pigments, which is comprised of a) a combination of at least two mineral or organic fillers or pigments, at least one of which has a surface with at least one hydrophilic site and the other at least has at least one organophilic site co-structured or co-adsorbed by being blended with b) at least one binding agent, which, when an acrylate polymer, has a specific viscosity of greater than 0.8, forms the composite compound.

2. The method of claim 1 , wherein the manufacture is the manufacture of paints.

3. The method of claim 1 , wherein the manufacture is the manufacture of plastics.

4. The method of manufacturing of aqueous suspensions of organic or mineral pigments or fillers, paper coating colors and/or paper filling or paper surface treating of claim 1 wherein the binding agent is polyacrylic acid.

5. The method of claim 1 , wherein the specific viscosity of the polyacrylate acrylate polymer ranges from 0.95 to 5.0.

6. A method of manufacturing of aqueous suspensions of organic or mineral pigments or fillers, paper coating colors and/or paper filling or paper surface treating, comprising:

preparing said materials from a composite compound of mineral or organic fillers or pigments, which is comprised of a) a combination of at least two mineral or organic fillers or pigments, at least one of which has a surface with at least one hydrophilic site and the other at least has at least one organophilic site co-structured or co-adsorbed by being blended with b) at least one acid monomer containing (co)polymer binding agent whose acid groups are unneutralized or partially neutralized, the acidic monomers being selected from the group consisting of (meth)acrylic acid, itaconic acid, crotonic acid, fumaric acid, maleic anhydride, isocrotonic acid, aconitic acid, mesaconic acid, sinapic acid, undecylic acid, angelic acid, their respective esters.

7. The method of manufacturing of aqueous suspensions of organic or mineral pigments or fillers, paper coating colors and/or paper filling or paper surface treating according to claim 6 , wherein the acid monomer containing copolymer binding agent is comprised of 90% by acrylic acid and 20% by wt tristyrylphenol methacrylate copolymerized with 25 moles of ethylene oxide.
