Abstract
A smoke generating composition consisting essentially of metallic oxide ammonium perchlorate, an organic chlorine donor and a plasticizer and a buffering agent. The metallic oxide includes zinc oxide as one of its components and ammonium perchlorate as well as polychloroisoprene as components of the chlorine donor. All of the components are mixed in such proportions that a neutral fog within the range of pH 5-7 is formed.
Claims4
A smoke or fog generating composition consisting essentially of
- 29-33% wt. zinc oxide;
- 31.3-40.4% wt. ammoniumperchlorate
- 10-17% wt. polychloroisoprene;
- 3.8-14.3% wt. a buffering agent;
- and
- 6-12% wt. of a plasticizer
- all of the components being mixed in such proportion to one another that a neutral smoke or fog is formed by said composition upon its ignition within the range of pH 5-7.
