| titleOfInvention | Room temperature curing polyurethane adhesive system for PBX pouring explosive |
| abstract | The invention belongs to the technical field of cast explosives and solid propellants, and provides a room temperature curing polyurethane adhesive system for PBX cast explosives, which aims to solve the problems that the existing HTPB type cast PBX explosives are high in curing and forming temperature and long in room temperature curing time, solid components are easy to settle and the like. Prepared by polyatomic alcohol, a plasticizer, polyisocyanate and a curing catalyst according to a certain proportion. The processing performance is good, the viscosity is low in the early stage of solidification, the viscosity is slowly increased, and the removal of bubbles in the construction process is facilitated; the method is suitable for the explosive charging process construction process of PBX cast explosives with different sizes; the viscosity of the system is obviously increased in the later curing period, and the problem of solid phase sedimentation in the curing and forming process of PBX cast explosive can be inhibited to a certain extent; on the basis of meeting various construction indexes, the temperature requirement in the curing process is obviously reduced, the curing molding is realized under the condition of room temperature, and the effects of improving the safety in the production process of PBX cast explosive, the quality of cast explosive columns and saving energy are obvious. |
