资源简介：
An aqueous binder composition is provided 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 dedusting 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.
