Abstract:
Disclosed are a separator for a rechargeable battery including a porous substrate and a heat resistance layer on at least one surface of the porous substrate wherein the heat resistance layer includes an acryl-based copolymer, an alkali metal, and a filler and the acryl-based copolymer includes a unit derived from (meth)acrylate or (meth)acrylic acid, a cyano group-containing unit and a sulfonate group-containing unit, and a rechargeable lithium battery including the same.
Abstract:
The invention relates to mixtures containing, as component (A) ammonium polyphosphate and, as component (B) a soluble ionic compound which contains sulfate and/or is capable of releasing sulfate ions. The invention also relates to a method for producing said type of mixtures and to the use thereof.
Abstract:
Modified copper chromite spinel pigments exhibit lower coefficients of thermal expansion than unmodified structures. Three methods exist to modify the pigments: (1 ) the incorporation of secondary modifiers into the pigment core composition, (2) control of the pigment firing profile, including both the temperature and the soak time, and (3) control of the pigment core composition.
Abstract:
A flame-resistant multi-layer composite (10) comprises a carbon-containing substrate (14); a first polymer layer (16) applied on the substrate in a first plasma-polymerization (pp-) process step; and a second polymer layer (18) applied on the first plasmapolymer layer in a second pp-process step. The pp-layers are of different composition. One of the pp-layers is obtained from plasma-polymerization of phosphorus-containing precursors or a mixture of precursors comprising phosphorus-containing precursors. The other pp-layer is obtained from plasma-polymerization of nitrogen-containing precursors or a mixture of precursors comprising nitrogen-containing precursors. The multi-layer composite may be used in intumescent, halogen-free, flame retardants. Improvements in both time-to-ignition (increase) and peak of heat release rate (decrease) were observed. The substrate could be any carbon-based polymer, flexible or rigid, in film, foam or fabric form. Deposition of the pp-layers can be performed at atmospheric pressure in open reactors, which facilitates implementing the production process on an industrial line.
Abstract:
According to one aspect, the invention relates to a fire-retardant composition containing colloidal silica as a binder, huntite (Mg3Ca(CO3)4) or hydromagnesite (Mg5(CO3)4(OH)2·4H2O) or their combination (Mg3Ca(CO3)4/Mg 5 (CO 3 ) 4 (OH) 2 ·4H 2 O) as a fire retardant, mineral wool fibres, and water. The invention further relates to a process for manufacturing the above said fire-retardant composition and a mineral wool-based insulation product (B) having at least one mineral wool-based layer (12, 12") and the above said fire-retardant composition (22) applied as a paste onto at least one surface of at least one mineral wool-based layer (12, 12") of the mineral wool-based insulation product (B).
Abstract:
The invention relates to a water-based coating composition with the following components: 21-51% water, 4-13% diatomite C110 (Celite C110®), 2-6% calcined alumina, 0.3-2% hexylenglycol, 16-47% elastomeric acrylic resin, 0.7-3% acrylic thickener, and 0.7-3% ammonium hydroxide. Preferably, the composition also includes optionally the following components in order to provide the insulating, corrosion-inhibiting, self-extinguishing, impermeable, epoxy and ecological properties: 2-6% titanium bioxide, 4-13% precipitated calcium carbonate, 2-6% dibutyl phthalate, 0.3-2% texanol, 0.3-2% fungicide, and 0.3-2% anti-foaming agent. By means of these ranges, a variety of applications can be covered for which the composition of an insulating, corrosion-inhibiting, self-extinguishing, impermeable, epoxy and ecological coating was developed.
