摘要:
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. Coating colors, uncoated filling compound and sheets of base paper for coating containing them.
摘要:
The present invention relates to the technical mineral matter suspension sector, and, before and/or after drying, their applications in the fields of paper, paint and, after drying, plastics. It also relates to the use of a copolymer having at least one alkoxy or hydroxy polyalkylene glycol function grafted onto at least one ethylenically unsaturated monomer, as agent whose role is to enhance the gloss of the final product and, in particular, the gloss of the sheet of paper, irrespective of the viewing angle.
摘要:
The invention relates to the use of a slightly anionic and water-soluble copolymer, as a dispersing agent and/or an agent for assisting the grinding of pigments and/or mineral fillers in aqueous suspension giving on the one hand a low Zeta potential to the aqueous suspensions of the said fillers and/or pigments and on the other hand affording an electro-steric stabilization of the said suspensions. The invention also relates to the said aqueous suspensions of mineral pigments and/or fillers and their uses in the fields of paper, such as the manufacture or coating of paper, and drilling muds used for petroleum prospecting or extraction. The invention also relates to the use of the said dispersing agents and/or agent for assisting the grinding in the field of paints and plastic materials such as thermoplastic or thermosetting resins.
摘要:
The present invention is directed to a process for the preparation of an aqueous suspension of self-binding pigmentary particles comprising the following stages: (a) forming one or more aqueous suspensions of at least one inorganic matter comprising calcium carbonate; (b) forming or obtaining one or more aqueous solutions or suspensions or emulsions of at least one binder; and (c) co-grinding the aqueous suspension or suspensions obtained in stage a) with the aqueous solutions or suspensions or emulsions obtained in stage b) in a mill so as to obtain an aqueous suspension of self-binding pigmentary particles.
摘要:
The invention consists of a process for preparation of self-binding pigmentary particles, dry or in aqueous suspension or dispersion, using in a particular stage of the process a reverse emulsion formed from a dispersion in an oily phase of water particles and of at least one polymer of acrylamide with an acrylic monomer.
摘要:
The invention concerns a process for the manufacture of self-binding pigmentary particles, dry or in aqueous suspension or dispersion, containing at least one inorganic matter and at least one binder, where the said process comprises the following stages: a) forming one or more aqueous suspensions of at least one inorganic matter and introducing them into a mill with a view to stage c), b) forming or taking one or more aqueous solutions or suspensions or emulsions of at least one binder and introducing them into a mill with a view to stage c), c) co-grinding the aqueous suspension or suspensions obtained in stage a) with the aqueous solutions or suspensions or emulsions obtained in stage b) so as to obtain an aqueous suspension of self-binding pigmentary particles, d) possibly co-grinding the aqueous suspension or dispersion obtained in stage c) with one or more aqueous solutions or suspensions or emulsions of at least one binder, e) possibly drying the aqueous suspension obtained in stage c) or in stage d). f) increasing the concentration of the aqueous suspension obtained at stage c) or d) through thermal or mechanical concentration, g) dispersing the aqueous suspension obtained at stage f) through using at least one dispersing agent and/or at least one wetting agent.
