Synthesis of a Series of Dual-Functional Chelated Titanate Bonding Agents and Their Application Performances in Composite Solid Propellants.

Titanate-based bonding agents are a class of efficient bonding agents for improving the mechanical properties of composite solid propellants, a kind of special composite material. However, high solid contents often deteriorate the rheological properties of propellant slurry, which limits the application of bonding agents. To solve this problem, a series of long-chain alkyl chelated titanate binders, -n-octyl-, -dihydroxyethyl-lactic acid-titanate (DLT-8), -n-dodecyl-N, -dihydroxyethyl-lactic acid-titanate (DLT-12), -n-hexadecyl-, -Dihydroxyethyl-lactic acid-titanate (DLT-16), were designed and synthesized in the present work.
