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.
纤维绝缘产品具有水性粘合剂组合物,其中包括碳水化合物和交联剂。在示例性实施例中,基于碳水化合物的粘结剂组合物还可包括催化剂、偶联剂、加工助剂、交联密度增强剂、扩展剂、防潮剂、扣油、着色剂、腐蚀抑制剂、表面活性剂、pH 值调节剂及其组合。碳水化合物可以是天然的,从可再生资源中提取。此外,碳水化合物聚合物的葡萄糖当量(DE)可以是 2 到 20。在至少一个示例性实施方案中,碳水化合物是水溶性多糖,如糊精或麦芽糊精,交联剂是柠檬酸。有利的是,碳水化合物的粘度低,在中等温度下即可固化。这种不含甲醛的环保型粘合剂可用于制作隔热材料和无纺布切股毡。此外,还提供了一种制造纤维绝缘产品的方法。
