    摘要: Aqueous binder compositions with reduced rates of salt precipitation are described. The compositions may include a carbohydrate and a sequestrant for sequestering one or more multivalent ions (e.g., Ca2+, Mg2+, Ba2+, Al3+, Fe2+, Fe3+, etc.). The sequestrant reduces a precipitation rate for the multivalent ions from the aqueous binder composition. Methods of reducing salt precipitation from a binder composition are also described. The methods may include the steps of providing an aqueous binder solution having one or more carbohydrates. They may also include adding a sequestrant for one or more multivalent ions to the aqueous binder solution. The sequestrant reduces a precipitation rate for the multivalent ions from the binder composition.

    摘要: Fibrous insulation products have an aqueous binder composition that includes a carbohydrate and a crosslinking agent. In exemplary embodiments, the carbohydrate-based binder composition may also include a catalyst, a coupling agent, a process aid, a crosslinking density enhancer, an extender, a moisture resistant agent, a deducting oil, a colorant, a corrosion inhibitor, a surfactant, a pH adjuster, and combinations thereof. The carbohydrate may be natural in origin and derived from renewable resources. Additionally, the carbohydrate polymer may have a dextrose equivalent (DE) number from 2 to 20. In at least one exemplary embodiment, the carbohydrate is a water-soluble polysaccharide such as dextrin or maltodextrin and the crosslinking agent is citric acid. Advantageously, the carbohydrates have a low viscosity and cure at moderate temperatures. The environmentally friendly, formaldehyde-free binder may be used in the formation of insulation materials and non-woven chopped strand mats. A method of making fibrous insulation products is also provided.
