摘要:
Carbon black with an OAN, measured on the beaded carbon black, of less than 120 ml/100 g. A process for the preparation of the carbon black is described, wherein a salt solution is converted into an aerosol and this is then introduced into the carbon black formation zone. The carbon black can be used in inks, paints, lacquers, printing inks and ink-jet inks, and for coloring plastics.
摘要:
Aqueous carbon black dispersions contain carbon black and cationic and non-ionic surfactants in addition to water. The dispersions are produced by dispersing the carbon black and the other components in water with bead mills, ultrasonic mills or an Ultra Turrax mixer. The dispersions can be used to produce inks, lacquers and printing inks.
摘要:
A pigment preparation, containing a pigment and/or carbon black and a polymer and/or a surfactant selected from the group of cross-linked polyoxyethyleneacrylic acid, fatty alcohol polyglycol ethers, polyvinylpyrrolidone, alcohol alkoxylates, lignin sulfonates, alkylphenol polyglycol ethers, naphthalene sulfonic acid derivatives or mixtures thereof which is prepared from an aqueous dispersion by freeze-drying. The pigment preparation can be used for coloring purposes and/or to provide antistatic characteristics in water-based coloring and lacquer systems, disperse dyes, printing inks, inking systems and coating systems.
摘要:
The subject of the invention is a process for the manufacture of (iodoorganyl)alkoxysilanes of the general formula: ##STR1## in which R.sup.1 is an alkylene group, R.sup.2 is an alkoxy group and R.sup.3 and R.sup.4 an alkoxy group and/or an alkyl or aryl group, whereby the chlorine or bromine compound corresponding to that of formula (1) is caused to react with stoichiometric to double molar quantities of an inorganic iodine donor in the presence of 0.01-5 mol % of an organic substituted onium salt of nitrogen, phosphorus, arsenic or antimony or an organic substituted sulfonium salt or a crown ether as catalyst, in certain solubilizing agents.
摘要:
The invention relates to a carbon black having an aggregate size distribution which has a (d90-d10)/d50 ratio of less than or equal to 1.1. The carbon blacks are produced by admixing hot air if desired to a gas mixture comprising a carrier gas and a carbon black feedstock, passing the gas mixture into a burner pipe, burning the gas mixture at the burner pipe openings, and drawing the flames under suction, together with the ambient air drawn in freely under suction from the outside, through a cooled, narrowing gap, and carrying out cooling, the cooled, narrowing gap having a height (h) to width (b) ratio of 1-100, the width (b) being 0.5 to 10 mm, and the flow rate at the narrowest point of the gap being 10-200 m/s. The carbon blacks of the invention can be used as non-reinforcing filler, reinforcing filler, UV stabilizer, conductive black, pigment or reducing agent.
摘要:
Ink jet ink containing at least one pigment and at least one oxidized carbon black.The ink jet ink is prepared in a process wherein the pigment is dispersed in at least one solvent, followed by addition of the oxidized carbon black and renewed dispersing.The ink jet ink can be used for printing textiles, metal, foil, film, sheet, glass and paper.
摘要:
The present invention is directed to carbon black granules containing a sorbitan triester. In addition, a process for the production of these carbon black granules is described, in which a powdered carbon black or beaded carbon black is beaded with a sorbitan triester. The carbon black granules can be used in polymer blends, lacquers, inks or pigments.
摘要:
Aqueous carbon black dispersions, wherein the carbon black dispersions contain no wetting agent and contain at least one ozone-oxidized carbon black. The dispersions are produced by dispersing ozone-oxidized carbon black and other constituents in water. The dispersions may be used for the production of inks, printing inks and water-based lacquer systems.

摘要:
Aqueous carbon black dispersions contain carbon black and surfactants, in addition to water. The dispersions are produced by dispersing the carbon black and the other constituents in water, using bead mills, ultrasonic mills and/or an ultra-turrax. The aqueous carbon black dispersions can be used to produce printing inks such as ink-jet inks or writing inks.
