摘要:
The present invention relates to treated mineral filler products comprising a) at least one mineral filler, b) a treatment layer located on the surface of said mineral filler(s), said treatment layer comprising at least one saturated C8 to C24 aliphatic carboxylic acid; and at least one di and/or trivalent cation salt of one or more saturated C8 to C24 aliphatic carboxylic acid, wherein the weight ratio of all of said aliphatic carboxylic acid salt(s):all of said aliphatic carboxylic acid(s) is from 51:49 to 75:25; and said treatment layer is present in an amount of at least 2.5 mg/m2 of said mineral filler. Furthermore the present invention relates to processes to prepare such treated mineral filler products, and to their uses, notably in plastic applications, and especially in polypropylene (PP)- or polyethylene (PE)-based breathable or extrusion coating film applications.
摘要:
The present invention consists of a process of preparation of at least one mineral matter and/or of at least one pigment, including a calcium carbonate made at once partially organophilic and partially hydrophilic, in which the carbonate is blended and/or ground and/or concentrated in an aqueous medium, in the presence of at least one salt of ethylene acrylic acid, one dispersing agent and/or one grinding aid agent, which is introduced before and/or during this treatment stage.Another object of the invention lies in the aqueous dispersions and suspensions of calcium carbonate thus obtained. They may be dried and the dry pigments obtained also constitute an object of the invention.Use of these aqueous dispersions and these dry pigments in the field of plastic, paints and paper constitutes another object of the invention.
摘要:
The present invention relates to the domain of mineral filler treatment processes. The process for the preparation of a treated mineral filler product comprises the following steps: (a) treating at least one dry mineral filler with at least one Group II or Group III salt of a C8 to C24 aliphatic monocarboxylic acid to produce an intermediate mineral filler product; followed by (b) treating the intermediate mineral filler product of step (a) with at least one C8 to C24 aliphatic monocarboxylic acid to produce a treated mineral filler product. Applications in particular to prepare treated mineral filler products (such as Ca carbonate) to be used in plastic applications such as in polypropylene (PP)- or polyethylene (PE)-based breathable or extrusion coating film applications.
摘要:
The present invention relates to a process for preparing self-binding pigment particles from an aqueous mineral pigment material suspension having a solid content of 45 to 80 wt.-%, based on the total weight of the suspension.
摘要:
The present invention relates to a process for the production of a surface-treated calcium carbonate, the use of this surface-treated calcium carbonate in a process for the control of organic material in an aqueous medium, as well as to a composite of surface-treated calcium carbonate and organic material, such as a composite of surface-treated calcium carbonate and to the use of such a composite.
摘要:

The invention further relates to a process for preparing such treated mineral filler products, and to its preferred use in the field of plastic applications, and in particular polypropylene (PP)- or polyethylene (PE)-based breathable or extrusion coating film applications.
摘要:
The invention relates to a process for manufacturing aqueous mineral material suspensions or dried mineral materials using at least one lithium ion neutralised water-soluble organic polymer, the ground mineral materials obtained by this process, the use of the mineral materials in paper, paints and plastics, as well as the use of the lithium ion neutralised water-soluble organic polymer in the manufacturing process as a dispersing and/or grinding enhancer.
摘要:
The present invention concerns a calcium carbonate containing material having increased bulk density at equal or improved flowability, and a method of producing such a material. The inventive process comprises the step of contacting a calcium carbonate containing mineral powder with a solution or emulsion or dispersion of a binder.
