Fibrous glass binders

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

Fire-resistant mineral fibers, structures employing such mineral fibers and processes for forming same

Abstract: 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.

Fibrous insulation product having inorganic binders

Abstract: A fiber insulation product is provided which includes a fibrous material having a binder (106) 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 (10) having a compressed board (12) encased in a evacuated jacket (14), and in high-temperature, low-smoke, odorless, evacuated atmosphere and building insulation applications.

Fibrous glass insulation assembly

Abstract: 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.

Fibers having phosphorus-containing coatings

Abstract: Mineral fibers are provided with a phosphorus-containing coating to impart high-temperature resistance without substantially affecting mechanical performance. Preferred mineral-fiber compositions according to the invention with relatively high levels of SiO2 and low levels of Al2O3 and Fe2O3 compositions may advantageously be used for insulation. Such compositions have high-temperature resistance and high biosolubility, yet have properties which allow current processes to fabricate them into insulation. Preferably, the mineral fibers have a KI value ≥ 40.

Curable aqueous composition and use as fiberglass nonwoven binder

Abstract: This invention relates to a formaldehyde-free curable aqueous composition containing a polyacid, a polyol and a phosphorous-containing accelerator. The composition may be used as a binder for heat resistant nonwovens such as nonwovens composed of fiberglass.

Binders and materials made therewith

Abstract: A curable aqueous composition is disclosed comprising a carbohydrate, a crosslinking agent, and an amine base, wherein the curable aqueous composition has a pH adjusted by the amine base. Further disclosed is a method of forming a curable aqueous solution.

Polycarboxy/polyol fiberglass binder of low pH

Abstract: Provided is a fiberglass binder which contains a polycarboxy polymer and a polyol, with a pH of the binder being no greater than 3.5. It is further preferred that the polycarboxy polymer has a molecular weight of less than 10,000, and more preferably about 5000 or less. The binder also preferably includes a catalyst which is an alkali metal salt of a phosphorus polyol is preferably triethanolamine. The binder also preferably includes a catalyst which is an alkali metal salt of a phosphorus-containing organic acid. The resultant binder, particularly when used in preparing fiberglass products, provides minimal processing difficulties and a product with excellent recovery and rigidity.

Formaldehyde-free aqueous binders

Abstract: Formaldehyde-free aqueous binders containing: A) a polymer consisting of 5 to 100 wt% of an ethylenically unsaturated acid anhydride or an ethylenically unsaturated bicarboxylic acid, the carboxylic acid groups of which can form an anhydride group, and B) an alkanol amine with at least two hydroxyl groups.

Process for crosslinking hydrogels with bis- and poly-2- oxazolidinones

Abstract: The invention relates to a process for the gel or surface postcrosslinking of water-absorbing polymers in which the polymers are treated with a surface postcrosslinking solution and during or after the treatment are postcrosslinked and dried by means of an increase in temperature, the crosslinker being a compound of the formula in which R1 and R2 independently of one another are H, hydroxyl, phenyl or C1-C6-alkyl, R3 is hydrogen, C1-C12-alkyl, C1-C12-alkenyl or C6-C12-aryl and R4 and R5 independently of one another are C1 -C 12-alkyl, C1 -C 12-alkenyl, C6 -C 12-aryl, hydroxyl, C1 -C 12-alkoxy or hydrogen, dissolved in an inert solvent, to water-absorbing polymers which can be obtained by said process, and to their use in hygiene articles, packaging materials and nonwovens.
