| description | The invention relates to a novel Schiff base bonding agent, a preparation method and a solid propellant. According to the bonding agent, polyethylene polyamine is introduced into a polyether amine molecular chain through a classical aldehyde amine condensation reaction, and the activity of terminal amino of the polyethylene polyamine is effectively inhibited in the form of a Schiff base functional group, so that the novel bonding agent has physical adsorption and chemical adsorption effects on AP; optimal ranges of repeated units in polyether amine and polyethylene polyamine molecules in the raw materials are designed, and compared with an existing Schiff base bonding agent, the novel bonding agent can ensure that terminal amino has proper reaction activity and can also ensure the flexibility of the chain, and therefore, the strength and the elongation of the propellant can be improved at the same time; and the novel bonding agent is suitable for large-scale industrial production and has a wide application pr |
