Effects of the Binders on the Storage Stability of the Silicon Delay Composition

Abstract:

To study effects of binders on storage stability of the silicon delay composition, sample B and C₁ were prepared separately by adding shellac and fluororubber(FPM₂₆₀₂) in basic formula A, and sample C₂ and C₃ were prepared by changing adding amounts and modes of fluororubber respectively. On conditions of 71°C and 92% humidity variation rule of burning rate and delay precision varying with time was studied. The results indicate that binders have function of “heat sink”, and reduce burning rate and delay precision of the delay composition, especially the effects of shellac are obvious. Under two kinds of storage conditions, sample B adding with shellac can obviously improve agents influenced by temperature and humidity. Increasing fluororubber contents the delay composition can also be improved influenced by temperature and humidity. Binders at constant amounts, fluororubber solution in adding directly to the composition in mixing process can improve the delay precision.
