Abstract:
This invention relates to a method for manufacturing a mineral wool board, comprising the following steps in the given order: providing mineral wool fibers having a fiber length of 50 to 800 μm; gluing the fibers with a liquid binder comprising phenolic resin, whereby the ratio of binder (based on the solids content of the resin of the binder) to mineral wool fibers is 5 to 30% by weight, and pressing the glued fibers using heat and pressure.
Abstract:
A method of manufacturing a mineral fibre thermal insulation product comprises the sequential steps of:
Forming mineral fibres from a molten mineral mixture; Spraying a substantially formaldehyde free binder solution on to the mineral fibres, the binder solution comprising: a reducing sugar, an acid precursor derivable from an inorganic salt and a source of nitrogen; Collecting the mineral fibres to which the binder solution has been applied to form a batt of mineral fibres; and Curing the batt comprising the mineral fibres and the binder which is in contact with the mineral fibres by passing the batt through a curing oven so as to provide a batt of mineral fibres held together by a substantially water insoluble cured binder.
Abstract:
The present invention relates to a method of draining water comprising the steps of:
providing a water drainage device, wherein the water drainage device comprises man-made vitreous fibres (MMVF) bonded with a cured aqueous binder composition; positioning the water drainage device in contact with the ground, wherein the water drainage device absorbs water and releases water to a recipient wherein the aqueous binder composition prior to curing comprises; a component (i) in form of one or more oxidized lignins; a component (ii) in form of one or more cross-linkers.
Abstract:
An un-reacted substantially formaldehyde free curable binder solution for binding loose matter consists essentially of a solution obtainable by dissolving a reducing sugar, an ammonium salt acid precursor, optionally a carboxylic acid or a precursor thereof and optionally ammonia in water.
Abstract:
Embodiments of the present technology may include a curable, carbohydrate binder composition. The composition may include a carbohydrate. The composition may also include a urea compound. The composition may further include a nitrogen-containing compound. The nitrogen-containing compound may not be the urea compound.
Abstract:
An aqueous binder for mineral fibers, in particular glass fibers, includes at least one ammonium lignosulfonate or one alkali metal or alkaline earth metal salt of lignosulfonic acid, and at least one carbonyl compound of formula: R—[C(O)R1]x (I) in which: R represents a saturated or unsaturated and linear, branched or cyclic hydrocarbon radical, a radical including one or more aromatic nuclei which consist of 5 or 6 carbon atoms, a radical including one or more aromatic heterocycles containing 4 or 5 carbon atoms and an oxygen, nitrogen or sulfur atom, it being possible for the R radical to contain other functional groups, in particular hydroxyl or alkoxy groups, especially methoxy groups, R1 represents a hydrogen atom or a C1-C10 alkyl radical, and x varies 1 to 10, the binder being devoid of hydrogenated sugar and of melamine.
Abstract:
A curable formaldehyde-free binding composition for use with fiberglass is provided. Such curable composition comprises an aldehyde or ketone and an amine salt of an inorganic acid. The composition when applied to fiberglass is cured to form a water-insoluble binder which exhibits good adhesion to glass. In a preferred embodiment the composition when applied to fiberglass provides a sufficient blackness required in facer products.
Abstract:
The invention is drawn to a glass fiber mesh fabric coated with an organic polymer coating having a reduced gross heat of combustion (less than 3.0 MJ/kg), said polymer coating comprising (i) from 60 wt % to 99.9 wt % of poly(vinylidene chloride) (PVDC) or a copolymer thereof; and (ii) from 0.1 wt % to 40 wt % of a formaldehyde-based resin selected from melamine-formaldehyde resins, phenol-formaldehyde resins, urea-formaldehyde resins or a combination thereof. The invention also provides a method for producing such a coated glass fiber mesh fabric.
Abstract:
A high color quality, fire resistant, pinstripe decorative fiberglass laminate is provided. The pinstripe decorative fiberglass laminate includes colored unidirectional glass fiber rovings in a fire resistant resin matrix. Pigmented unidirectional glass fiber rovings provide a pinstriped effect with substantial color richness and aesthetic quality. For light colored pinstripes, colored unidirectional glass fiber rovings are impregnated with a melamine resin and cured to form the fire resistant, pinstripe decorative fiberglass laminate. For dark colored pin stripes, colored unidirectional glass fiber rovings are impregnated with a phenolic resin and cured to form the fire resistant, pinstripe decorative fiberglass laminate.
