Abstract
Embodiments of the present technology may include piping insulation products. The piping insulation product may include glass fibers and a binder. The binder may include cured products from a binder composition that includes a carbohydrate, a nitrogen-containing compound, and a catalyst that catalyzes the reaction between the carbohydrate and the nitrogen-containing compound. The catalyst may be water soluble before curing but water insoluble after curing. The nitrogen-containing compound may include an amino-amide, an amine salt of an organic acid, an ammonium salt of a carboxylic acid, or a reaction product of a urea compound and an aldehyde-containing compound. The catalyst may include a polymer including a sulfate, sulfonate, phosphate, or phosphonate moiety. The catalyst may be a crosslinker.
Claims20
A piping insulation product comprising glass fibers and a binder, wherein the binder comprises cured products from a carbohydrate binder composition comprising a carbohydrate, a nitrogen-containing compound, and a catalyst that catalyzes a reaction between the carbohydrate and the nitrogen-containing compound, wherein:
- the nitrogen-containing compound is selected from the group consisting of an amino-amide, an amine salt of an organic acid, an ammonium salt of a carboxylic acid, and a reaction product of a urea compound and an aldehyde-containing compound,
- the catalyst is water insoluble in the piping insulation product,
- the catalyst comprises a polymer comprising a sulfate, sulfonate, phosphate, or phosphonate moiety, and
- the catalyst is a crosslinker.
A piping insulation product comprising glass fibers and a binder, wherein the binder comprises cured products from a carbohydrate binder composition comprising a carbohydrate, a nitrogen-containing compound, a catalyst that catalyzes a reaction between the carbohydrate and the nitrogen-containing compound, and a counter ion formed by a reaction of an acid with a base comprising ammonia, a substituted amine, or a polyamine, wherein:
- the catalyst is water insoluble in the piping insulation product, and
- the catalyst is a crosslinker.
