Preparation of graft modification protein-based adhesive
InactiveCN101302410ASolve application problemsIncrease added valueGraft polymer adhesivesAdhesiveRedox
The invention relates to a method for preparing graft modification protein adhesives, belonging to the adhesive technical field. The method obtains the graft modification protein adhesives by adopting redox system initiator to react for a period of time at a certain temperature and linking vinyl monomer branched chains on a protein trunk chain. During the production and use processes, substances such as formaldehydes and so on are not released, thereby the method is favorable for environmental protection; and simultaneously the method can increase the added value of protein products and has important economic value. Because more hydrophobic groups are linked on the protein trunk chain, the interaction between the graft modification protein adhesives obtained and molecular groups on the wood surface is stronger and the adhesives are difficult to damage by water molecules, thereby the graft modification protein adhesives have good bonding strength and superior water resistance. The method widens the application environment and solves the problem which disturbs actual application of the protein adhesives for a long time, consequently having obvious technical advance.
