Abstract
A silicon-based cured foam material for rapidly blocking a forest fire includes: a binder, a foaming agent, a coagulant, an aggregate, and water, where when the water is in 100 parts by mass, the binder is in 4.5 parts to 6 parts by mass, the foaming agent is in 0.9 parts to 1.2 parts by mass, and the coagulant is in 7.5 parts to 10 parts by mass; a mass ratio of the aggregate to the water is 1:(10-20); and the foaming agent is a mixture of sodium dodecyl sulfate and dodecyl dimethyl betaine or a mixture of tetradecyl dimethyl benzyl ammonium chloride and dodecyl dimethyl betaine. The silicon-based cured foam material has a high viscosity and excellent elasticity due to gelation properties. And because solid particles are attached to bubble walls, a particle-containing covering layer can still be formed after bubble bursting to isolate a vegetation from oxygen.
