摘要:
A dry mixture is made of a non-modified fluorinated polymer, particularly a deformable, web-forming polytetrafluoroethylene, in powder and/or fibre form, an inorganic hydrophilic material as a powder and a porous hydrophilic material or a pore forming agent. The mixture is pressed into a cake. The cake is subjected to rolling steps. Between rolling steps the cake is turned over an angle.
摘要:
The invention relates to a foam composition for construction use, more particularly for the filling of joints or the joining of components, comprising a foamable aqueous phase and a blowing agent, which are foam-forming with one another on nozzle discharge, with the foamable aqueous phase comprising at least one organic polymer and inorganic constituents. The inorganic constituents comprise a silicate which is chemically dissolved in the aqueous phase and whose solution is film-forming, with the organic polymer being present in the form of a dispersion or aqueous solution, and which when foamed with the silicate solution produces, together, a silicate-polymer foam, with the organic polymer being present, on the basis of its solids content, in an amount of ≥ 3 wt% in the aqueous phase, and, additionally, the water-soluble silicate being present, on the basis of its solids content, in an amount of ≥ 3 wt% in the aqueous phase, and with the organic polymer and the water-soluble silicate, based in each case on their solids content, being present in a weight ratio of 20:1 to 1:20 in the aqueous phase.
摘要:
The invention relates to fiber-containing pasty construction materials, containing a) one or more fillers, b) optionally additives, characterized in that they contain c) fibers, d) one or more polymers based on one or more ethylenically unsaturated monomers, having a glass transition temperature Tg of ≥ -15°C, e) ≤ 5% by weight hydraulically setting binders and f) water, wherein the information in % by weight relates to the dry weight of the fiber-containing pasty construction materials.
摘要:
A process for the improvement of adhesion between fluoropolymers or fluorocopolymers and inorganic compounds as well as composites made by this process are disclosed. The inorganic compound is coated with an adhesion promoter. Contacting the adhesion-promoted inorganic compound with the fluoropolymer or fluorocopolymer and heating develops the adhesive bond.
摘要:
An intumescent fire seal comprises ceramic or like fibres mixed with exfoliating graphite and/or sodium silicate in granular and/or powder and/or chip form. The fire seal may comprise a non-woven mat or sheet, a block or other shaped product and may be enveloped wholly or partially in metallic foil or the like. Alternatively, the fire seal may comprise a liquid or paste which can be applied directly to a surface to be fire proofed.

摘要:
The noise insulating material comprises a binder resin, sound barrier filler, liquid rubber and fire-resistant fiber. The incorporation of fire-resistant fiber in the binder resin reinforces the resin matrix to prevent melting and shedding of the binder resin upon exposure to a flame. Being qualified as a quasi-incombustible material, this noise insulating material can be used in a broad range of applications.
摘要:
A method for preparing an inorganic foamed material, characterized by kneading an inorganic filler with vinyl chloride resin, zinc oxide, a foaming agent and a plasticizer in order to obtain a compound, and themally foaming said compound in a mold.
