A binding compound for mineral or organic fibres, includes from 40 to 95 wt % of furan resin, and from 5 to 60 wt % of at least one reducing sugar and/or of at least one non-reducing sugar, relative to the total dry weight of the composition, the binding composition having a dry matter content between 0.5 to 50 wt %.

Binding compound based on furan resin, reducing sugar and/or non-reducing sugar

The present invention relates to a thermosetting binder composition containing water and a water-soluble oligomeric ester of at least one saccharide chosen from reducing sugars, non-reducing sugars and hydrogenated sugars, the hydrogenated sugars being chosen from the group consisting of erythritol, arabitol, xylitol, sorbitol, mannitol, iditol, maltitol, isomaltitol, lactitol, cellobitol, palatinitol, maltotritol and hydrogenation products of hydrolyzates of starch or of lignocellulose materials, and of at least one polycarboxylic acid, the binder composition having a dry matter content of between 50% and 80% by weight, the water-soluble oligomeric ester representing at least 80% by weight, preferably at least 90% by weight, of the cry matter content of the thermosetting binder composition, and the thermosetting binder composition containing less than 10% by weight, preferably less than 5% by weight, with respect to its dry matter content, of free sorbitol. It also relates to the use of such a binder composition for the manufacture of a product based on mineral or organic fibers which are bonded by an insoluble organic binder.

Binder composition on an oligoester basis, production thereof, and use thereof for binding organic or mineral fibres

The present invention concerns a method for manufacturing an insulating product based on organic or mineral fibers, which comprises—applying an aqueous binder composition to organic or mineral fibers, preferably mineral wool fibers; —heating the fibers bonded with the aqueous binder composition so as to evaporate the volatile phase of the aqueous binder composition and to bring about the thermal curing of the non-volatile residue, or packaging the organic or mineral fibers bonded with the aqueous binder composition for the purpose of storage and/or transport, the aqueous binder composition having a pH of between 1.0 and 6.5, preferably between 1.5 and 5.0, and comprising: a) at least one carbohydrate selected from hydrogenated sugars, reducing sugars, non-reducing sugars and mixtures thereof, (b) at least one polycarboxylic acid or an anhydride of such an acid, (c) from 1 to 35% by weight, relative to the total weight of components (a), (b) and (c), of a water-soluble, amine-containing phenolic resin consisting essentially of phenol-formaldehyde condensates and phenol-formaldehyde-amine condensates.

A process for manufacturing a thermoset polyester foam includes the following successive steps: (a) providing an expandable and thermosetting composition containing a polyol component including at least one element selected from glycerol, diglycerol and glycerol oligomers; a polyacid component including citric acid; a surfactant selected from alkyl polyglycosides and mixtures of an anionic surfactant and a cationic surfactant, and an esterification catalyst; (b) introducing the expandable and thermosetting composition into a mold or applying the expandable composition to a support; and (c) heating the expandable and thermosetting composition at a temperature at least equal to 135&#xb0; C. so as to react the polyol component with the polyacid component and form a block of thermoset polyester foam.

Thermoset polyester foams and manufacturing method

The invention relates to a process for the preparation of a shaped composite, comprising the preparation of a mixture into which fragments of mineral wool comprising a size comprising a sugar, a non-cement silica carrier distinct from the wool, a non-cement alkali metal carrier distinct from the wool, and water, are introduced, the non-cement silica carrier and the non-cement alkali metal carrier forming, with the water, a mineral binder which gradually solidifies around the solid particles present in the mixture, and then the shaping of the mixture into a shaped composite, in particular into briquettes. The invention also relates to a process for the manufacture of mineral wool, in which a molten mass is produced which is converted into mineral wool by means of a fiberizing device, the shaped composite being introduced as vitrifiable charge into a melting chamber, such as a cupola furnace.

Composite comprising a mineral wool comprising a sugar

A formaldehyde-free sizing composition for products based on fibers, in particular mineral fibers, such as glass or rock fibers, which includes: at least one non-reducing sugar, at least one catalyst for the dehydration of the non-reducing sugar, at least one amine, and at least one compound including activated ethylenic unsaturation(s).

Formaldehyde-free sizing composition for fibres, in particular mineral fibres, and resulting products

The present invention relates to an aqueous sizing composition for insulating products based on mineral wool, comprising

Binder composition for mineral wool

A formaldehyde-free sizing composition for products based on fibers, in particular mineral fibers, such as fibers of glass or of rock, includes at least one non-reducing sugar, and at least one inorganic acid ammonium salt, preferably chosen from ammonium sulfates, phosphates, nitrates and carbonates. Another subject matter of the present invention is the products thus obtained, in particular thermal and/or acoustic insulators based on mineral wool and veils of nonwoven mineral fibers, and their process of manufacture.
