The use of lignin as a rubber reinforcing agent

The outcome of the use of lignin as a rubber reinforcing agent. Characterized by the concentration of waste paper in the addition of formaldehyde formaldehyde resin made from lignin, and then joined the proportion of sulfur, zinc oxide and stearic acid, curing agent, curing promoter, activator vulcanization of rubber and to a certain temperature Under sulfide. The results will enable a large number of rubber filled in after the lignin without softeners increase not only save a lot of rubber, can be protected with a good quality of vulcanized rubber, vulcanization at the same time will not pollute the environment, waste paper can change Wei harm, so there are great social and economic benefits.
