Fire protection material, high-pressure storage tank coated with said material, methods for preparing same, and uses thereof

A process for preparing a fire-proof material for a high pressure storage tank, the fire-proof material including a matrix of thermosetting elastomeric resin in which endothermic fillers are incorporated, the matrix of thermosetting elastomeric resin being a matrix of silicone resin, comprising the following steps:

• a) preparing, at room temperature, a mixture including at least one precursor of the thermosetting elastomeric resin and at least one endothermic filler by gradually adding the at least one endothermic filler to the at least one precursor of the thermosetting elastomeric resin whereby a homogeneous dispersion is obtained;
• b) adding, to the mixture obtained in step a), an agent enabling the thermosetting elastomeric resin to be obtained from the at least one precursor, wherein the adding of the agent is performed at room temperature;
• and
• c) cold shaping the mixture obtained in step b) by casting, injection, or vacuum assisted transfer, into a mold on the high pressure storage tank to obtain the fire-proof material including the matrix of thermosetting elastomeric resin in which the endothermic fillers are incorporated.
