Lignin Adhesives TRIZ Cases
- Lignin-Based Phenolic Adhesives Without Premature Resin Gelation
Controlled lignin-aldehyde condensation prevents resin gelation while enabling biobased adhesives with PF-like dry bond strength.
- Lignin-Carbohydrate Bonding Resin for Fast Wet-Strength Insulation
A lignin, carbohydrate, and polyamine resin improves insulation wet strength, cures faster, and avoids formaldehyde-based bonding.
- Oxidized Lignin Adhesive for Wood Bonding Strength and Moisture Resistance
An aqueous adhesive composition uses oxidized lignins combined with cross-linkers to bond lignocellulosic materials.
- Functionalized Lignin Adhesive Bonding Strength
A functionalized lignin adhesive composition cures with a silyl ether hardener to form a durable resin.
- Natural Aromatic Polymer Binder for Fibrous Materials
A binder composition uses natural aromatic polymers to bind fibrous materials through caramelization and Maillard reactions.
- Formaldehyde-Free Lignosulfonate Binder for Mineral Fiber Mats
Replacing formaldehyde resins, this binder maintains mechanical strength and humidity resistance in bituminous waterproofing membranes.
- Lignin Adhesive Preparation via Self-Cross-Linking
Self-cross-linking of lignin molecules creates a strong adhesive while eliminating complex chemical modification steps and reducing energy consumption.
- Lignocellulose Composite Production via Free Radical Precursor
A lignocellulose composite production method combines substrates with a free radical precursor and polyphenolic material to form cured products.
