The invention relates to the technical field of
sponge, in particular to a thermoformable fire-proof
sponge. The thermoformable fire-proof
sponge is composed of the following raw materials in part by weight: 5 to 20 parts of PPG (
Polypropylene Glycol), 60 to 95 parts of POP (Polyether
Polyol), 1 to 9 parts of TDI (
Toluene-2,4-diisocyanate), 1 to 3 parts of MDI (Diphenyl-
methane-diisocyanate), 0.5 to 2 parts of H2O, 0.3 to 0.8 parts of SI (
Silicon), 0.01 to 0.05 parts of A-1, 1.1 to 1.5 parts of A-33, 1.1 to 1.5 parts of catalyst, 0.5 to 5 parts of white
carbon black, 10 to 30 parts of
calcium carbonate, 8 to 10 parts of openings agent, 5 to 20 parts of fire-proofing agent, and 2 to 6 parts of
flame composite agent. According to the invention, the thermoformable fire-proof sponge has the advantages of safety,
environmental protection and high
hardness; and the adhering tension is stronger, the structure is stable, and the compressive forming effect is good. The preparation method of the thermoformable fire-proof sponge is carried out under a normal pressure, so that the requirements on equipment and
energy consumption are low; the production and manufacture time is shortened; and the process cost is low.
