## 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.

## Claims

### Claim 1

A silicon-based cured foam material for rapidly blocking a forest fire, comprising: a binder, a foaming agent, a coagulant, an aggregate, and water, wherein when the water is in 100 parts by mass, the binder is in 4.5 parts by mass to 6 parts by mass, the foaming agent is in 0.9 part by mass to 1.2 parts by mass, and the coagulant is in 7.5 parts by mass to 10 parts by mass; a mass ratio of the aggregate to the water is 1:(10-20);
the foaming agent is a mixture of sodium dodecyl sulfate and dodecyl dimethyl betaine in a mass ratio of 8:2;
the binder is sodium silicate;
the coagulant is sodium dihydrogen phosphate;
the aggregate is at least one selected from a group consisting of a fly ash, nano-silica, and a quartz powder; and
a preparation method of the silicon-based cured foam material comprises the following steps:
(1) dissolving the foaming agent, the binder, and the coagulant separately in the water to obtain a foaming agent solution, a binder solution, and an coagulant solution, respectively;
(2) pouring the foaming agent solution, the binder solution, and the coagulant solution obtained in the step (1) into a stirrer, and adding the aggregate to the stirrer to obtain a mixed solution; and
(3) foaming the mixed solution through a combination of mechanical stirring and air injection.

### Claim 2 (depends on 1)

A preparation method of the silicon-based cured foam material according to claim 1, comprising the following steps:
