  • ANTIBACTERIAL COMPOSITION AND ANTIBACTERIAL STRUCTURE
    Publication number: 20200352175
    Abstract: An antibacterial composition is provided. The antibacterial composition includes a lignin, a solvent, and a silane compound. The lignin is dispersed in the solvent, and the silane compound is dispersed in the solvent. The antibacterial composition further includes an alkaline compound so that the pH of the antibacterial composition is greater than 7. The weight ratio of the lignin to the solvent is between 1:5 to 1:20, and the weight ratio of the lignin to the silane compound is between 50:1 to 200:1. In addition, an antibacterial structure is also provided.

  • Flame retardant agents and flame retardant materials comprising the same
    Patent number: 8445565
    Abstract: Disclosed is a flame retardant agent, including a nitrogen-based lignin formed by reacting 1 part by weight of lignin, 0.8 to 2.4 parts by weight of a nitrogen-containing compound, and 0.3 to 0.9 parts by weight of an aldehyde under an alkaline condition. The flame retardant agent can be added to thermoplastic or thermosetting resins to form flame retardant materials.
