Problems solved by technology

However, in the technology described in the above-mentioned documents, the physical properties of the cured product are inferior to those of the existing PFR resin, and the adhesive solution itself has almost no anti-corrosion effect, so the organic adhesive in the produced process water can only be bonded. Decompose the components of the agent or use other special equipment and processes for reuse

Embodiment 1

[0053] With 370kg of glucose (D-glucose) (solid content: 91% by weight), 70kg of glutamine (glutamine) (solid content: 98% by weight), 2.5kg of ammonium sulfate (ammonium sulfate) (solid content: 98% by weight %), 1.5kg of formaldehyde (formalin, UNID company) (solid content: 37% by weight), 3kg of dustproof oil (Dust Oil, Govi-Garo217S), 2kg of silicon-based waterproofing agent (KCC-SI1460Z) and 4050 kg of distilled water were added into the mixing container and stirred for 30 minutes, then the pH was adjusted to 8-9 with ammonia water, and the mixture was further stirred for 10 minutes to prepare an adhesive composition. The resulting adhesive composition had a solids content of approximately 9% by weight.

Embodiment 2

[0055] With 370kg of glucose (D-glucose) (solid content: 91% by weight), 70kg of glutamine (glutamine) (solid content: 98% by weight), 2.5kg of ammonium sulfate (ammonium sulfate) (solid content: 98% by weight %), 660kg of distilled water was added to the reactor outside the reactor provided with a jacket (jacket) that can use steam and cooling water to adjust the temperature, and the temperature of the reactant was maintained for 3 hours after being heated up to 85°C. Here, 3390 kg of distilled water at room temperature, 1.5 kg of formaldehyde (formalin, UNID company) (solid content: 37% by weight), 3 kg of dustproof oil (Dust Oil, Govi-Garo217S) and 2 kg of silicon After the waterproofing agent (KCC-SI1460Z) was added into the mixing container and stirred for 30 minutes, the pH was adjusted to 8-9 with ammonia water, and the mixture was further stirred for 10 minutes to prepare an adhesive composition. The resulting adhesive composition had a solids content of approximately ...

Embodiment 3

[0057] An adhesive composition was prepared in the same manner as in Example 1 except that 1.5 kg of glyoxal solution (solid content: 40% by weight) was used instead of formaldehyde. The resulting adhesive composition had a solids content of approximately 9% by weight.

Abstract

The present invention relates to a water-based adhesive composition that can reuse process water and a method for using it to bind fibrous materials. In more detail, it relates to an aqueous adhesive composition comprising more than one reducing sugar and more than one amino acid, As well as an aqueous adhesive composition with more than one aldehyde compound having a minimum inhibitory concentration (Minimum Inhibitory Concentration, MIC) of 1% or less and a method for using it to bond fibrous materials. Compared with the existing phenolic resin (PFR), the adhesive composition of the present invention is cheap and can show more than equal physical properties, and the final product does not contain or basically does not release toxic substances such as formaldehyde or phenol, During processing, the problem of odor, which is a defect of existing PFR resins, can be reduced. Compared with existing environmentally friendly resins that do not contain toxic substances such as formaldehyde or phenol, water resistance and tensile strength of processed products can be significantly improved. Mechanical properties such as hardness and dust rate, and because the adhesive solution has anti-corrosion properties, it is possible to reuse process water generated in the bonding process of fibrous materials using adhesive components without causing microbial contamination. corruption and thus economical.
