C. adding high-temperature resistant fiber loose cotton, high-temperature resistant alumina fine powder and an additive which are proportioned according to the weight fraction into a high-position mixing drum with an A stirrer and containing 8-10 times of high-temperature resistant silicon solvent for stirring for 45-60 minutes, feeding the high-temperature resistant fiber loose cotton, the high-temperature resistant alumina fine powder, the additive and the high-temperature resistant silicon solvent mixed material which are stirred and mixed for the first time into a low-position mixing drum with a B stirrer from the high-position mixing drum along a connecting pipeline for stirring for 15-20 minutes, positively rotating and conveying the high-temperature resistant fiber loose cotton, the high-temperature resistant alumina fine powder, the additive and the high-temperature resistant silicon solvent uniformly mixed casting material which are stirred and mixed again into a uniformly mixed casting material mixing and pouring material vacuum tank by a uniformly mixed casting material positive and negative rotating conveying pump, and sequentially injecting the uniformly mixed casting material mixing and pouring material into a prefabricated block heat insulation pad, After the high-temperature-resistant alumina fine powder, the additive and the high-temperature-resistant silicon solvent are uniformly mixed and poured into a prefabricated block heat-insulating pad negative pressure mould with a double-layer interlayer wall, the liquid high-temperature-resistant silicon solvent is pumped away by a liquid high-temperature-resistant silicon solvent pumpback and conveyed to a uniformly mixed and poured material blending vacuum tank through interlayer gaps and pressure difference to form a prefabricated block heat-insulating pad; naturally air-drying for 48 hours, and then drying for 48 hours at the temperature of 150-;
D. when the uniformly mixed casting material is conveyed to the uniformly mixed casting material blending vacuum tank in the forward direction by the forward and reverse conveying pump for uniformly mixed casting material and the uniformly mixed casting material of the high-temperature resistant fiber loose cotton, the high-temperature resistant alumina fine powder, the additive and the high-temperature resistant silicon solvent which are sequentially injected into the negative pressure die of the prefabricated block heat insulation pad with the double-layer sandwich wall is redundant, the forward and reverse conveying pump for uniformly mixed casting material is started, so that the forward and reverse conveying pump for uniformly mixed casting material rotates in the reverse direction, and the redundant high-temperature resistant fiber loose cotton, the high-temperature resistant alumina fine powder, the additive and the high-temperature resistant silicon solvent which are injected into the negative pressure die of the prefabricated block heat insulation pad with the double-layer sandwich wall are uniformly.
