专利汇可以提供Caseless smoke grenade including polyvinyl chloride binder专利检索,专利查询,专利分析的服务。并且A caseless smoke generating grenade consists essentially of a cast flexible main charge. The flameless pyrotechnic composition used in the main charge is comprised of substantially equal proportions of zinc oxide and a perchlorate oxidizer distributed throughout a plasticized polymeric resin fuel having a high halogen content. The composition is free of solvent and provides controlled burning coupled with excellent flexibility, cohesive strength and impact resistance.,下面是Caseless smoke grenade including polyvinyl chloride binder专利的具体信息内容。

  • 2. The composition of claim 1 wherein the polymeric resin includes polyvinyl chloride and the combustion temperature of the composition is about 500* C and less.
  • 3. The composition of claim 1 including a minor amount of a supplemental halogen donor capable of serving as an additional smoke forming component.
  • 4. The composition of claim 1 wherein the oxidizer is ammonium perchlorate.
  • 5. The composition of claim 1 wherein the plasticized resin fuel constitutes approximately one third the total weight of the pyrotechnic composition.
  • 6. The composition of claim 1 wherein the organic plasticizer and polymeric resin are present in substantially equal proportions by weight.
  • 7. The composition of claim 1 comprising 10-25 percent by weight polymeric resin, 10-25 percent by weight plasticizer, 20-35 percent by weight perchlorate oxidizer and 18-40 percent by weight zinc oxide.
  • 8. A caseless grenade comprised of a solid, flexible, impact resistant charge of a flameless pyrotechnic smoke generating composition comprising from about 15 to about 40 percent by weight zinc oxide, from about 15 to about 40 percent by weight oxidizer and at least 10 percent by weight of a plasticized vinyl polymer resin fuel, said resin having a moderate to high chlorine content, said composition exhibiting a combustion temperature well below 1,000* C.
  • 9. The caseless grenade of claim 8 wherein the charge includes up to about 35 percent by weight based on the weight of the pyrotechnic composition of an auxiliary agent for dispersion with the smoke upon combustion of the pyrotechnic composition.
  • 10. The caseless grenade of claim 9 wherein the auxiliary agent is a tear gas producing agent.
  • 11. The caseless grenade of claim 8 including an ignition mix and delay element for igniting the charge.
  • 12. The caseless grenade of claim 8 wherein the charge includes a color producing agent.
