Embodiment 1

[0038] With 376kg of glucose (D-glucose) (solid content: 91% by weight), 58kg of glutamic acid (glutamicacid) (solid content: 98% by weight), 2.4kg of glycerol triglycidyl ether (JSI company, EJ -300, solid content 99%, water solubility 75% by weight), 3kg of dust-proof oil (Dust Oil, GOVI-Garo217S), 2kg of silicon-based water repellent (KCC-SI1460Z) and 4050kg of distilled water into the mixing container, and use The adhesive was prepared by agitating with a mixer for 30 minutes. The resulting adhesive had a solids content of approximately 9% by weight.

Embodiment 2

[0040] 376kg of glucose (D-glucose) (solid content: 91% by weight), 54kg of L-asparagine (L-asparagine) (solid content: 98% by weight), 5kg of sulfuric acid (sulfuric acid, 98%), 2.4kg of glycerol triglycidyl ether (JSI company, EJ-300, solid content 99%, water solubility 70% by weight), 3kg of dustproof oil (GOVI-Garo217S), 2kg of silicon-based waterproofing agent (KCC- SI1460Z) and 4050 kg of distilled water were put into a mixing container and stirred with a mixer for 30 minutes to obtain an adhesive. The resulting adhesive had a solids content of approximately 9% by weight.

Embodiment 3

[0042] 376kg of glucose (D-glucose) (solid content: 91% by weight), 116kg of liquid phase lysine (L-lysine) (solid content: 50% by weight), 5kg of sulfuric acid (sulfuric acid, 98%), 2.4kg of glycerol triglycidyl ether (JSI company, EJ-300, solid content 99%, water solubility 70% by weight), 3kg of dustproof oil (GOVI-Garo217S), 2kg of silicon-based waterproofing agent (KCC- SI1460Z) and 3980 kg of distilled water were put into a mixing container and stirred with a mixer for 30 minutes to obtain an adhesive. The resulting adhesive had a solids content of approximately 9% by weight.

Abstract

The present invention relates to an aqueous binder composition and a method for binding fibrous materials by using same and more specifically to: an aqueous binder composition, which comprises one or more reducing sugars, one or more amino acids, and one or more polyglycidyl ether compounds of polyhydric alcohols, is inexpensive and yet can express the same or better physical properties in comparison with a conventional phenol formaldehyde resin (PFR), neither contains nor releases any toxicant such as formaldehyde or phenol, can reduce the issue of an unpleasant smell, which is a weakness of the conventional PFR, during processing, and can significantly improve the water resistance, mechanical properties such as tensile strength and hardness, and dust ratio of a processed product; and a method for binding fibrous materials by using the aqueous binder composition.

Description

technical field [0001] The present invention relates to a water-based adhesive composition and a method for binding fibrous materials using the composition, in more detail, relates to a water-based adhesive composition and a method for binding fibrous materials using the composition, The water-based adhesive composition comprises more than one polyglycidyl ether compound of reducing sugar, more than one amino acid and more than one polyalcohol, and compared with the existing phenolic resin (PFR), the price is low And it can show the same or better physical properties, and it does not contain or release toxic substances such as formaldehyde or phenol. When processing, it can reduce the problem of odor that is a defect of existing PFR resins, and can significantly improve the water resistance of processed products. , tensile strength and hardness and other mechanical properties and dust rate. Background technique [0002] PFR, which is inexpensive and has excellent physical p...
