Embodiment 1

[0038] 450 kg of fresh water was added to the vessel used to prepare the adhesive and the pH was adjusted to a range of 8 to 14 using ammonia. Then, 0.1 kg of γ-aminopropyltriethoxysilane (silane A-1100, obtained from DOW CHEMICAL), 1.5 kg of lignin (Borrespers AM320, MW=20,000 to 50,000, obtained from Borregaard) and as a coupling agent 2 kg of glutaraldehyde (50 wt% glutaraldehyde in water from Sigma-Aldrich) was added to the vessel, and the mixture was stirred for about 10 minutes. Next, 22 kg of D-glucose monohydrate (solid content: 91% by weight) and 20 kg of lysine (solid content: 98% by weight) were added to the container, and the resulting mixture was stirred for 30 minutes until dissolution was confirmed. Then, further 0.4kg organosilicon type hydrophobic agent (SI1460Z, obtained from KCC company) and 1kg dustproof oil ( 217 / S from Govi) was added to the vessel and the resulting mixture was stirred for about ten minutes to prepare the adhesive.

Embodiment 2

[0040] 450 kg of fresh water was added to the vessel used to prepare the adhesive and the pH was adjusted to a range of 8 to 14 using ammonia. Then, 0.1kg γ-aminopropyltriethoxysilane (silane A-1100, available from DOW CHEMICAL), 1.5kg lignin (dehydrated lignin, available from Domtar Company) and 2kg glutaraldehyde (50wt% glutaraldehyde An aqueous solution of dialdehyde, available from Sigma-Aldrich) was added to the vessel, and the mixture was stirred for about 10 minutes. Next, 21 kg of D-fructose (solid content: 99% by weight) and 19 kg of glutamine (solid content: 98% by weight) were added to the container, and the resulting mixture was stirred for 30 minutes until dissolution was confirmed. Then, further 0.4kg organosilicon type hydrophobic agent (SI1460Z, obtained from KCC company) and 1kg dustproof oil ( 217 / S from Govi) was added to the vessel and the resulting mixture was stirred for about ten minutes to prepare the adhesive.

Embodiment 3

[0042] 450 kg of fresh water was added to the vessel used to prepare the adhesive and the pH was adjusted to a range of 8 to 14 using ammonia. Then, 0.1kg of γ-aminopropyltriethoxysilane (silane A-1100, obtained from DOW CHEMICAL), 1.5kg of lignin (wheat straw lignin, obtained from WuXi lansen Chemicals Co., Ltd.) and 2kg of glutaraldehyde (50wt % glutaraldehyde solution, available from Sigma-Aldrich) was added to the vessel, and the mixture was stirred for about 10 minutes. Next, 21 kg of D-fructose (solid content: 99% by weight) and 19 kg of glutamine (solid content: 98% by weight) were added to the container, and the resulting mixture was stirred for 30 minutes until dissolution was confirmed. Then, further 0.4kg organosilicon type hydrophobic agent (SI1460Z, obtained from KCC company) and 1kg dustproof oil ( 217 / S from Govi) was added to the vessel and the resulting mixture was stirred for about ten minutes to prepare the adhesive.

Abstract

The invention relates to a binder composition comprising a natural aromatic polymer, and a method for binding a fibrous material by using the same.

Description

technical field [0001] The present invention relates to an adhesive composition and a method for bonding fibrous materials using the adhesive composition. More specifically, the present invention relates to an adhesive composition comprising a) one or more reducing sugars, b) one or more amino acids, c) one or more natural aromatic polymers, A derivative thereof or a salt compound thereof, d) one or more multifunctional aldehydes; and a method for bonding fiber materials using the adhesive composition. Background technique [0002] Although a technique of bonding fiber materials using phenolic resin has been developed, this technique has problems of poisonous raw materials used, foul smell of the resin, and the like. Therefore, people have begun to study various curing techniques to replace phenolic resins with different resins.
