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.
