The magnesium triisocyanurate can obviously improve the strength, rigidity and heat resistance of plastic products, and can make the products be used for a long time at about 250 ℃. Therefore, it is a novel cross-linking agent for preparing high-performance unsaturated polyester and acrylic resin products. The melamine cyanurate is a salt synthesized from melamine and cyanuric acid, belongs to a nitrogen series flame retardant, and has two forms of powder and granule. When the polyamide foam flame-retarded with this product is burned, the resulting carbon foam layer protects the polymer, insulating heat and oxygen.

S304, the radiator n conducts heat to the radiator n + 1;
the n radiators are distributed on the cable in total, so that heat can be transferred among the radiators on the whole cable through the radiating fins, and the cooling liquid of all the radiators is used for radiating heat, so that the temperature of the ignition point is further reduced, and the ignition point is prevented from being further increased to restart combustion.
S305 radiates the heat absorbed in the heat sink to the air.
The radiator is also provided with the heat dissipation protruding piece, and the heat of the cooling liquid can be dissipated to the air through the heat dissipation protruding piece, so that the heat dissipation performance is further improved, and the temperature of the ignition point is prevented from being continuously increased.
S104, heating sodium bicarbonate to decompose to generate steam and carbon dioxide;
referring to fig. 4, the specific steps are:
s401, after the flame retardant is used up, the cable continues to be heated;
the amount of flame retardant is limited and if one has not treated the fire after the flame retardant is used up, the cable will continue to be flame baked.
S402, directly absorbing heat by the radiating fins;
after the flame retardant is lost, the heat sink directly absorbs heat, thereby rapidly raising the temperature of the heat sink.
And S403, decomposing the sodium bicarbonate on the side of the radiating fin by heating.
The back of the radiating fin is provided with sodium bicarbonate with the molecular formula of NaHCO3Relative molecular mass 84.01. White crystalline powder. No odor, alkali, and water-soluble. Slowly decompose in humid or hot air to produce carbon dioxide, which is lost when heated to 270 ℃. The high-temperature carbon dioxide can be completely decomposed into sodium carbonate, water and carbon dioxide, the water can absorb heat and be gasified into steam to be discharged from the crevasses of the heat-resistant layer, and the carbon dioxide can isolate the air at the crevasses when being discharged from the crevasses, so that the continuous combustion of the carbon dioxide is further prevented.
S105, isolating and insulating water vapor and carbon dioxide from the wire core;
the water vapor generated at high temperature may cause short-circuiting of the cable, and thus an insulation process for the core of the wire is required.
S106 shields the wire core.
The insulation of the wire core can prevent electric signals or electric energy transmitted in the wire core from leaking or being interfered by external electromagnetic fields, so that the electric energy transmission can be kept normal.
Through adding at the heat-resistant layer inside and establishing the fin, make the heat of ignition point can be fast along the cable conduction, then absorb the cooling in the multistage a plurality of radiators that transmit on the cable, thereby can reduce the temperature of ignition point fast, heat-resistant layer inside has set up the fire retardant, make the heat-resistant layer after burning out the breach, thereby the fire retardant can completely cut off oxygen and prevent the burning, after the fire retardant has consumed, the fin direct heating makes sodium bicarbonate be heated and decompose into carbon dioxide and water again, can take away heat and isolated air simultaneously, thereby can prevent the wire core to take place the burning as far as possible, the flame retardant ability of cable has greatly been promoted, thereby it only has single-deck flame retardant material to have solved current cable, flame retardant ability is limited can not satisfy actual need's problem.
