Lignin and its structureLignin is a complex class of organic polymers that form the key structural material in the support tissues of most plants. [1] Lignin is of particular importance in the formation of cell walls, especially in wood and bark, because they are rigid and less prone to decay. Chemi Read More

Lignin biosynthesis begins in the cytosol, where glycosylated monolignol is synthesized from the amino acid phenylalanine. These first reactions are shared with the phenylpropanoid pathway. The attached glucose makes them water soluble and less toxic. Polymerization begins once the m-glucose is remo Read More

The method of using lignin as rubber reinforcing agent belongs to the technical field of Lignin Application in rubber industry. The key point is to add formaldehyde into the concentrated papermaking waste liquid to make lignin formaldehyde resin, and then add sulfur, zinc oxide, stearic acid, vulcanizing agent, vulcanization accelerator, vulcanization activator and rubber in proportion to vulcanize at a certain temperature.
