FIELD OF THE INVENTION The present invention relates to a method of manufacturing fire-resistant silicone foam. Currently, various methods of manufacturing silicone foam are being considered, but the silicone foam has excellent heat resistance, can withstand a wide range of usage conditions, and can be easily injected into the voids of the penetration parts of electric wires, cables, bus bars, etc. There is no method for manufacturing highly fire-resistant silicone foam that can be dismantled and repaired when needed for expansion or removal. The present invention has been made with the object of eliminating the above-mentioned drawbacks and providing a method for manufacturing a silicone foam with high fire retardant properties. That is, the gist of the present invention is to provide (1) a mixture of polydimethylsiloxane, phenylmethylvinylsiloxane-terminated dimethylsiloxane, hydroxy-terminated blocked polydimethylsiloxane, and polymethylvinylsiloxane cyclic compound;
A platinum-based catalyst with an amount of 5 x 10 -4 to 2 x 10 -3 parts by weight of platinum is mixed with quartz powder and carbon.
A composition prepared by mixing 5 to 30 parts by weight of aluminum silicate to 100 parts by weight of a mixture adjusted to a viscosity of 4000 to 10000 CPS (20°C), and (2) polydimethylsiloxane, phenylmethylvinylsiloxane terminal block. A mixture of polydimethylsiloxane and polymethylhydrodienesiloxane is mixed with quartz powder and platinum inorganic pigment at 4,000 to 10,000 CPS (20
5 to 30 parts by weight of the mixture adjusted to
parts by weight of zinc oxide are mixed to form a foam at room temperature. Mixtures within the scope of compositions (1) and (2) of the invention include:
Forms a honey fireproof foam at room temperature (preferably between 15 and 25°C, particularly preferably between 20 and 25°C). Below this range, the fire resistance is low and a stable, tight foam cannot be obtained. If it exceeds this range, the fireproofing properties will be high, but the viscosity will be high, making mixing difficult and causing poor dispersion, and there will be parts of the liquid that do not form a foam. The reason for the improvement in fire protection performance is considered as follows.
This is because the silicon dioxide in the silicone form left over from combustion and the aluminum silicate and zinc oxide in the composition solidify at high temperatures, creating a barrier against heat and flame. The viscosity of the compositions of claims (1) and (2) is within the range of pouring workability, mixing workability, and fire resistance.
4000~10000CPS is appropriate, and 5000~8000CPS is preferable. Magnesium hydroxide, hydrated alumina (aluminum hydroxide), commonly used flame retardants
Since the foam formation speed is significantly accelerated and the foam starts to form at the same time as mixing, it is impossible to put it into practical use because there is no time for pouring. Magnesium silicate, calcium carbonate, and quartz powder can also be used, but their effect on increasing fire resistance is small. Next, Examples of the present invention are shown in Table 1 along with comparative examples.
