With the rapid development of social economy and science and technology, people's material and cultural level has been continuously improved. High-rise buildings, underground works, large space buildings, power communication departments, and large-scale enterprises have emerged continuously. There are many internal wire and cable applications, in order to prevent cable fires. Occurrence and development to reduce the economic losses caused by the use of aluminum hydroxide fire retardant coatings as flame retardant protection for cables, to prevent the spread of initial fires and slow fires, to ensure the safety of the country and people's lives and property, and to promote firefighting. Significance.
As a special coating, cable fire retardant coating consists of two parts: base material and flame retardant additive (aluminum hydroxide). In addition to the decorative effect of ordinary paint and physical protection of cable substrate, special function of flame retardant and fire resistance is required. .
Several experiments, such as the effect of aluminum hydroxide flame retardant materials on the fire performance, smoke generation and anticorrosion of fire retardant coatings, lead to the following conclusions:
1. Aluminum hydroxide not only has a low flame retardant effect, but also greatly improves the fire performance and physical and chemical properties of the cable fire retardant coating, and at the same time reduces the cost.
2. When adding aluminum hydroxide flame retardant, it has obvious smoke-eliminating effect on cable fireproof coating, which can make fireproof coating not only produce smoke and toxic gas when burning, but also have good flame retardant and heat insulation effect.
3. In the cable fire retardant coating, the technical route of adding aluminum hydroxide flame retardant is adopted, so that when the cable fireproof coating is obtained, the coating expands and foams well and densely, forming a dense and uniform fireproof heat insulation layer to the cable. Provide effective fire protection. However, when the amount of aluminum hydroxide flame retardant is 7%, the cable fire retardant coating has good fireproof performance, good physical and chemical properties and garment resistance.
