Reactive polyurehthane adhesive for explosive to metal bonding |
| 摘要 |
An adhesive may bond a plastic bonded explosive to a metal surface. The adhesive may include a mixture of hydroxyl-terminated polybutadiene (HTPB) and isophorone di-isocyanate (IPDI) in a weight ratio in the range of about 5 to 1 to about 10 to 1. The adhesive may include a solvent and/or a catalyst. |

1. A method of adhering a plastic bonded explosive to a metal surface, comprising:
providing an adhesive,
wherein the adhesive consists essentially of a mixture of hydroxyl-terminated polybutadiene (HTPB) and isophorone di-isocyanate (IPDI) in a weight ratio in a range of about 5 to 1 to about 10 to 1, and a solvent; applying the adhesive to the metal surface; and partially curing the adhesive and casting explosive material on a partially cured said adhesive thereby forming a reactive interface intermediate the casting explosive and the partially cured said adhesive,
wherein said applying the adhesive includes dipping the metal surface of a shaped charge, liner into the adhesive for forming a substantially uniform thin layer of the adhesive. |
