The present invention relates to a water-soluble pre-reacted binder composition, a method of its manufacture, a use of said pre-reacted binder composition, a method of manufacturing a collection of matter bound by a polymeric binder, a binder solution or dispersion comprising said pre-reacted binder composition, as well as products comprising the pre-reacted binder composition in a cured state.

Binders and associated products

A method of manufacturing a mineral fiber insulating board comprising i) spraying a formaldehyde-free aqueous binder solution onto a plurality of mineral fibers to provide uncured binder disposed on the plurality of mineral fibers, ii) passing the plurality of mineral fibers having uncured binder disposed thereon through a curing oven to cure the uncured binder and provide the mineral fiber insulating board with a cured binder disposed on the plurality of mineral fibers in about 0.5%-15% by weight as determined by loss on ignition, wherein the binder is based on reducing sugar(s) and the cured binder includes at least one reaction product of the reducing sugar(s) and an amine reactant.

Mineral fibre board

In a stack of composite wood boards, the wood boards comprise wood particles and an organic binder.

Composite wood board

A method of manufacturing a mineral fiber insulating board comprising i) spraying a formaldehyde free aqueous binder solution onto a plurality of mineral fibers, the aqueous binder solution comprising binder reactants comprising a) a reducing sugar reactant and b) an amine reactant, wherein the reducing sugar reactant is selected from the group consisting of: a reducing sugar; a reducing sugar yielded by a carbohydrate in situ under thermal curing conditions; and combinations thereof, wherein the percent by dry weight of the reducing sugar reactant with respect to the total weight of the binder reactants in the binder solution ranges from about 73% to about 96%, and wherein the percent by dry weight of the amine reactant with respect to the total weight of the binder reactants in the binder solution ranges from about 4% to about 27%, ii) dehydrating the aqueous binder solution such that a dehydrated binder is disposed on the plurality of mineral fibers, and iii) curing the dehydrated binder on the plurality of mineral fibers to provide cured binder in about 0.5%-15% by weight as determined by loss on ignition.

The present application relates to wood boards, particularly post-cured wood boards and more particularly to particle board with excellent swelling properties; it also relates to a process for production of such boards.
