摘要： The present invention relates to an aqueous binder composition and a method for binding fibrous materials by using the same, and more specifically, relates to an aqueous binder composition and a method for binding fibrous materials by using the same comprising one or more reducing sugars, one or more amino acids, and one or more ionic compounds including metal cation having oxidation number of 2 or higher. The present invention provides the same or better physical properties with lower price compared to traditional phenol formaldehyde resin (PFR), does not include or release toxic materials such as formaldehyde or phenol, and may decrease intoxication which is a vulnerable point of traditional PFR during manufacturing and remarkably enhances the mechanical properties such as water resistance, tensile strength and hardness of the manufactured product.

摘要： The present invention relates to an aqueous mixed binder composition and a method for binding fibrous materials by using the same, and more specifically, relates to an aqueous mixed binder composition comprising a) one or more reducing sugars, b) one or more amino acids, and c) one or more condensed products formed by combining amide-based compound or phenol-based compound with formaldehyde, and a method for binding fibrous materials by using the same. The aqueous mixed binder composition of the present invention provides equal or better physical properties with lower price compared to traditional phenol formaldehyde resin (PFR) used independently, its final product releases almost no toxic materials since the contents of toxic materials such as formaldehyde or phenol are decreased to ppm units, may decrease bad odor which is a weak point of traditional PFR during manufacturing and may remarkably enhance the mechanical properties-such as water resistance, tensile strength and hardness-and dust rate of the manufactured product and dust rate compared to the traditional eco-friendly resin which does not comprise toxic materials such as formaldehyde and phenol, and is economical since process water can be recycled without putrefaction due to microorganisms which occurs during the manufacturing process of fibrous materials to which it is bound by the binder composition since the binder solution has preservative ability.
