Application of lignin

1, phenolic resin (Phenolic resin)
Enzymatic lignin can be used instead of phenol or with a small amount of phenol for the preparation of phenolic resin in an amount of 5-25%.
2, Polyurethane (Polyurethane)
Direct reaction with isocyanate for the preparation of polyurethane, the amount of 5-20%
Application effect:
The application of polyurethane in the modified polyurethane, the lignin content of less than 20% or less, the polyurethane still has a good strength, elongation> 300% with the lignin mass fraction continues to increase, elongation decreased significantly.
(2) In the case of modified polyurethanes instead of polyethylene glycol, the tensile strength of elastomers increased by 4 times when the content of lignin content was 25%. When the content of lignin was less than 20%, the polyurethane remained Has a good flexibility.
Solvent Resistance: With the increase of enzymatic lignin content, the enzymatic hydrolysis of lignin polyurethane significantly improved the solvent resistance of cyclohexanone.
Heat resistance: enzymatic lignin polyurethane and polyurethane elasticity of the heat resistance is almost the same.
3, epoxy resin (Epoxy resin)
Enzymatic hydrolysis of lignin can replace part of the bisphenol-A, directly with epichlorohydrin reaction Preparation of epoxy resin or epoxy resin adhesive, the added amount of 5-15%.
4, rubber additives (Rubber additives)
Enzymatic lignin can be directly added or prepared into lignin derivatives added to natural rubber, synthetic rubber, improve the mechanical properties of rubber, anti-aging properties, heat resistance, flame retardant properties, the added amount of 5-20%
Application effect:
Enzymatic lignin epoxy resin and enzymatic lignin graft copolymer on rubber and plastics.
5, concrete additives (Concerte additives)
Enzymatic hydrolysis of lignin derivatives as a polymer modified cement concrete additives, replace part of the petrochemical raw materials, the modified effect is good. The addition amount is 5-25%.
6, plastic modifier (Plastic modifier)
(PVC), polypropylene (PP), polyethylene (PE) and ABS, PC and other engineering plastics, improve the mechanical properties of the material, the resistance of the lignin can be copolymerized with other macromolecules. Burning, anti-aging performance, high economic value, the added amount of 5-15%.
7, Dye dispersing agent (Dye dispersing agent)
Enzymatic lignin can be used for the preparation of surfactants, the dye industry to provide new dye dispersant, the added amount of 5-25%.
8, asphalt modifier (Asphalt modifier)
Enzymatic hydrolysis of lignin can be fully compatible with the asphalt component, with it instead of or in place of other synthetic polymers can be good performance, environment-friendly modified asphalt, the added amount of 5-15%.
9, polymer technology lignin (Graft lcopolymer of Lignin)
Can be directly and acrylamide, acrylic acid ester, acrylonitrile, maleic anhydride, styrene and other polymer monomer graft copolymerization, the formation of new lignin derivatives for polymer modification, is a The additive for improving the compatibility of the polymer is 50-90%.
10, building insulation materials (Building thermal insulation materials)
Enzymatic hydrolysis of lignin in polyurethane phenolic resin and other building insulation materials used in applications, can greatly improve its performance.
