Claims
- 1. A method for preparing a red phosphorous smoke agent wherein particulate red phosphorous is coated with a polymer consisting essentially of the step of mixing particulate red phosphorous with a non-swollen rubber latex selected from the group consisting of natural and synthetic rubber latex.
- 2. The method of claim 1 wherein the red phosphorous is present in an amount of from 32 to 92 percent and the latex (contains 63% polymer) is present in an amount of from 68 to 8 percent of the mixture.
- 3. The method of claim 2 further including the step of adding a curative to the red phosphorous and latex mixture.
- 4. The method of claim 3 wherein the curative is present in an amount of 1 percent of the mixture.
- 5. The method of claim 4 wherein the mixture is dried to give a red phosphorous smoke agent composition containing 75 to 95 percent red phosphorous, 25 to 5 percent latex polymer and 0 to 1 percent curative.
- 6. The method of claim 5 wherein the mixture is dried by heating in an oven at 90.degree. to 100.degree. C. for two hours.
- 7. The method of claim 5 further including the step of extruding the mixture after it has been dried to about 9.0 percent moisture to produce a red phosphorous smoke agent pellet containing 95 percent red phosphorous and 5 percent latex polymer.
- 8. The method of claim 7 wherein the step of extruding the mixture is performed through use of a high energy pellet mill.
- 9. The method of claim 7 further including the step of curing the red phosphorous pellet by completely drying said red phosphorous pellet.
- 10. The method of claim 9 wherein the curing is performed by oven drying at 90.degree. to 100.degree. C. for two hours.
- 11. The method of claim 5 wherein the latex polymer is butyl rubber.
- 12. The method of claim 7 wherein the latex polymer plasticizer is butyl rubber.
