Thermoformable fire-proof sponge and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of sponges, in particular to a heat-pressable fireproof sponge and a preparation method thereof. Background technique [0002] With the continuous development of the economy and the improvement of living standards, people's requirements for the indoor environment continue to increase. It is often necessary to decorate homes and business places. In order to meet people's social activities and living needs, it is often necessary to use foam, sponge and other decorations. Materials to rationally and perfectly organize and shape an aesthetic and comfortable indoor environment. In addition, in order to inspire children's intelligence and increase children's fun of playing, children's toys made of foam and sponge, such as floor mats and puzzles, have been widely consumed. widely welcomed by readers. [0003] Traditional foams or sponges are generally made of PE and PU materials. However, due to the high expansion...

Problems solved by technology

[0003] Traditional foams or sponges are generally made of PE and PU materials. However, due to the high expansion factor during the foaming process, the airtight pore structure is too fluffy, resulting in poor adhesion and tensile strength of the prepared foam or sponge. Insufficient and easy to tear; in addition, the traditional foam or sponge has poor flame retardancy and is easy to burn in case of fire, which poses a great safety hazard
