Abstract

A fire suppression composition includes starch, a pseudo-plastic, high yield, suspending agent, and hydrophobic agglomerating material.

Claims (19)

1. A powdered fire suppression suspension forming composition comprising;

35-65 wt % starch;

25-55 wt % pseudo-plastic, high yield, suspending agent; and

0.1-10 wt % hydrophobic agglomerating material.

2. The powdered fire suppression suspension forming composition according to claim 1 wherein the composition forms a suspension composition when added to water, whereby the composition clings to a surface positioned in any orientation, and forms an exterior intumescent char coating upon fire contact.

3. The powdered fire suppression suspension forming composition according to claim 1 further comprising clay.

4. The powdered fire suppression suspension forming composition according to claim 1 wherein the pseudo-plastic, high yield, suspending agent comprises polyacrylate.

5. The powdered fire suppression suspension forming composition according to claim 1 wherein the powdered composition comprises;

40-60 wt % starch;

30-50 wt % pseudo-plastic, high yield, suspending agent;

1-5 wt % hydrophobic agglomerating material.

6. The powdered fire suppression suspension forming composition according to claim 5 further comprising clay.

7. A powdered fire suppression suspension forming composition comprising;

40-60 wt % starch;

30-50 wt % pseudo-plastic, high yield, suspending agent;

1-5 wt % hydrophobic agglomerating material; and

clay.

8. The powdered fire suppression suspension forming composition according to claim 7 wherein the composition forms a suspension composition when added to water, whereby the composition clings to a surface positioned in any orientation, and forms an exterior intumescent char coating upon fire contact.

9. The powdered fire suppression suspension forming composition according to claim 7 wherein the pseudo-plastic, high yield, suspending agent comprises polyacrylate.
