Lignin

Lignin (Latin, English, German: Lignin) is a complex organic polymer that forms an important structural material in the supporting tissues of vascular plants and some algae. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they confer rigidity and are not susceptible to decay. Chemically, lignin is a cross-linked phenolic polymer.

1. Lignin is the main by-product of cellulose industry
2. Can be used as epoxy resin, rubber and thermoplastic additives
3. Can be used as polymer raw materials
4. Can be used as animal feed additive
The method of using lignin as rubber reinforcing agent belongs to the technical field of lignin application in rubber industry. The main point is to add formaldehyde to the concentrated paper waste liquid to make lignin formaldehyde resin, and then add sulfur, zinc oxide, stearic acid, vulcanization agent, vulcanization accelerator, vulcanization activator and rubber at a certain temperature for vulcanization. The method can make the rubber filled with a lot of lignin without adding softener, which not only saves a lot of rubber, but also can obtain the vulcanized rubber with excellent properties, at the same time, the vulcanization will not pollute the environment with dust, but also make the waste liquid of papermaking become harmful and beneficial, which has great social and economic benefits.
