Application of thick fire retardant coatings in cables

With the rapid development of science and technology, every household is using electricity, in which cables play a crucial role. Computers are developed on the basis of thick fire-retardant coatings and combined with their own requirements. The performance and weather resistance are relatively good, and the coating is relatively thin. When encountering fire, the thick fireproof coating can generate a uniform and dense foam sponge to turn the heat insulation layer, which has a better effect of heat insulation and fire protection, so as to achieve To protect the cable and prevent the spread of fire, the editor will talk to you about the application of thick fire retardant coatings in cables.

With the rapid development of modern social science and technology, the use environment of cables and the way of radiation have gradually become diversified, so some performances of traditionally used water-based fireproof coatings need to be improved to meet the needs of different use environments of cables. The most widely used is the thick fireproof coating, which has good fireproof performance. If it is used in cable tunnels, cable trenches, and cable shafts where the space is narrow and not ventilated, special attention should be paid to the rear fireproofing. Coating, it has the decorative function of ordinary paint, and has the function of physical protection of the cable substrate. As a layer, the fire retardant coating behind the computer has the special function of flame retardant and fire protection, which requires it to be within a certain temperature range. It can be foamed to form a fire-proof and heat-insulating layer. The rubber-like material used in the cable is a highly elastic body and needs to be moved frequently. This requires that the rear-type fire-proof layer of the cable should have sufficient internal expansion and contraction performance. It has good adhesion, no corrosive coating, good decoration, and good greenhouse curing. The above requirements solve the problem of connectivity between the thick fireproof coating and the substrate.

The choice of flame retardants has a great influence on the fireproof and heat insulation performance of thick cable fireproof coatings. Flame retardants are another key component of cable fireproof coatings. It is necessary to refer to relevant materials at home and abroad, combined with domestic resources, and conduct a single functional experimental study on the pre-selected and combined flame retardant materials. Through thermogravimetric and differential thermal analysis, determine the thermal decomposition and flame retardancy of raw materials, classify them on the basis of thick fire retardant coatings, and then observe the synergistic effect through experiments, so that the selected flame retardant materials are determined through analysis and experiments. The selected flame retardant needs to cooperate with other components in the cable fire retardant coating, so that the cable fire retardant coating has the above-mentioned excellent physical and chemical properties, and expands and foams to form a firm and dense thermal insulation layer when exposed to fire.
