A formaldehyde-free curable aqueous composition containing polyvinyl alcohol, a multi-functional crosslinking agent, and, optionally, a catalyst. The composition may be used as a binder for non-woven products such as fiberglass insulation. The non-woven products are formed by contacting the formaldehyde-free curable aqueous composition with fibrous components and the mixture is cured to form a rigid thermoset polymer providing excellent strength and water resistance of the cured nonwoven product.
一种无甲醛可固化的水性组合物,包含聚乙烯醇、多功能交联剂和可选的催化剂。该组合物可用作无纺织品的粘合剂,例如玻璃纤维绝缘材料。无纺织品通过将无甲醛可固化的水性组合物与纤维组分接触形成,混合物经固化后形成坚硬的热固性聚合物,提供了固化的无纺织品的优异强度和耐水性。
