Fibers having phosphorus-containing coatings

A fiber insulation product is provided which includes a fibrous material having a binder dispersed throughout. The binder comprises an inorganic material having thermoplastic properties. Preferably, the binder is a low-melting glass composition or a glass-forming compound such as, for example, boric acid. The insulation product is ideally suited for use in insulation panels having a compressed board encased in a evacuated jacket, high temperature, low smoke, odorless and building insulation applications.

Mineral fiber compositions with increased levels of SiO.sub.2 and reduced levels of Al.sub.2 O.sub.3 and Fe.sub.2 O.sub.3 compositions are suitable for insulation. The compositions have high temperature resistance and high biosolubility, yet have properties which allow current processes to fabricate them into insulation. The mineral fibers also meet proposed German regulations regarding K1.gtoreq.40.

Mineral fibers and their compositions

Vacuum insulation panels include an insulating media made up of glass fibers having a carbonized asphalt coating thereon. When such carbon-coated glass fibers are used as fillers for metal jacketed vacuum insulation panels, the resulting panels can be used for substantially higher temperature applications. The carbon on the carbon-coated fibers can be activated to absorb any outgassing that occurs from the insulation media within the panels to help ensure satisfactory vacuum levels over time.

An improved fibrous glass insulation assembly (10) having a fibrous glass body (12), a moisture barrier (14) that substantially encloses the fibrous glass body (12), and a desiccant (18) positioned adjacent the fibrous glass body (12) and within the moisture barrier (14). The fibrous glass body (12) is sufficiently encapsulated or enclosed by the moisture barrier (14), the moisture barrier (14) sufficiently retards the passage of moisture therethrough, and the desiccant (18) is disposed in a sufficient quantity so that enough moisture is removed to improve the recovery performance of the fibrous glass body (12), from a recoverable compressed state, and/or to improve the stiffness performance of the fibrous glass body (12), once the glass body (12) has recovered. Thus, by improving the stiffness performance, the present invention can make it easier to install the recovered fibrous glass body (12), and by improving the recovery performance, the present invention can result in the installed fibrous glass body (12) exhibiting better insulation characteristics.

Fibrous glass insulation assembly

A method for making dual-glass fibers includes supplying first and second molten glass to a rotating spinner having an orificed peripheral wall, where the first glass has a higher viscosity than that of the second glass, centrifuging the first and second glasses through the orifices as molten dual-glass streams, maintaining the dual-glass streams at a temperature sufficient to enable the second glass to flow around the first glass, and cooling the dual-glass streams to make dual-glass fibers.

Method for making dual-glass fibers by causing one glass to flow around

An improved fibrous glass insulation assembly is disclosed. The insulation assembly includes at least one fibrous glass body enclosed by a vapor barrier plastic outer layer or by a bag or package. A desiccant is provided adjacent the fibrous glass body to remove moisture.

A fibrous glass binder comprises a polycarboxy polymer, a .beta.-hydroxyalkylamide, and an at least trifunctional monomeric carboxylic acid.

Fibrous glass binders

A fibrous glass binder comprises a polycarboxy polymer, a monomeric trihydric alcohol and catalyst comprising an alkali metal salt of a phosphorous-containing organic acid.

Mineral fibers, and products (e.g., building insulation products) formed of mineral fibers are treated, and thus rendered fire-resistant, by placing a phosphate-containing compound onto or in close proximity to the mineral fibers. The phosphate-containing compound is at least one which forms a high-temperature protective coating or layer on the surfaces of the mineral fibers. A preferred product of the invention will include two mineral wool layers with a septum carrying the phosphate-containing compound interposed therebetween. Exemplary phosphate-containing compounds include monoammonium phosphate, diammonium phosphate, dicalcium phosphate, monocalcium phosphate, phosphoric acid, aluminum phosphate, tetrasodium pyrophosphate, tetrapotassium pyrophosphate, sodium hexametaphosphate, potassium tripolyphosphate, sodium tripolyphosphate, ammonium polyphosphate, monosodium dihydrogen phosphate, and mixtures thereof.

Fire-resistant mineral fibers, structures employing such mineral fibers

Glass fiber insulation bonded with a UV cured system is disclosed. Specific wavelengths of UV radiation were found that penetrate through the wool pack and yield a uniformly cured polymer throughout the thickness of insulation.

A thermosetting additive comprising, in its preferred form, the 2-hydroxyethyl acrylate adduct of poly(styrene-co-maleic anhydride), is blended with polyester-based thermosetting resins to produce molding compounds having improved surface characteristics.

Thermosetting additives for polyester-based molding compounds

Thermoplastic additives comprising the esterification product of a polyol with dimer and trimer acids are blended with thermosetting resins to reduce the shrinkage of the latter on molding.

Moldable compositions comprising thermosetting polyester resin and

A glass fiber wool binder composition comprising a phenolic resole resin, animal bone glue, a sulfite process lignin and dicyandiamide is disclosed. When a binder composition of this invention is employed on glass fibers to produce uncured glass fiber wool, the uncured wool exhibits improved integrity, thus facilitating alignment of uncured wool in mold contours and the production of molded products.
