Biodegradable suspension forming compositions
A fire suppression composition includes starch, a pseudo-plastic, high yield, suspending agent, hydrohopbic agglomerating material, and a neutralizer.
1. A powdered fire suppression composition comprising;
35-65 wt % starch;
25-55 wt % pseudo-plastic, high yield, suspending agent;
0.1-10 wt % hydrophobic agglomerating material; and
0.5-15 wt % neutralizer.
2. A powdered fire suppression composition according to claim 1 wherein the composition forms a suspension composition when added to water; the suspension composition having a pH in the range of 5.0 to 8.0; whereby the composition clings to a surface positioned in any orientation, and forms an exterior intumescent char coating upon fire contact.
3. A powdered fire suppression composition according to claim 1 wherein the neutralizer comprises caustic soda.
4. A powdered fire suppression composition according to claim 1 wherein the pseudo-plastic, high yield, suspending agent comprises a mixture of an acrylic acid copolymer cross linked with a polyalkenyl polyether and a synthetic smectite clay.
5. A powdered fire suppression 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; and
0.5-10 wt % neutralizer comprising basic material.
6. A powdered fire suppression composition according to claim 5 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.
