Application of Aluminum Hydroxide Fireproof Coating in Wire and Cable
With the rapid development of social economy and science and technology, the continuous improvement of people's material and cultural level, high-rise buildings, underground projects, large space buildings, power communication departments, and large enterprises continue to appear, and there are many applications of internal wires and cables. In order to prevent the occurrence and development of cable fires, in order to reduce the economic losses caused by them, the use of aluminum hydroxide fireproof coating as the flame retardant protection of cables is of great significance for preventing initial fires and slowing down the spread and expansion of fires, protecting the safety of the country and people's lives and property, and promoting fire protection.
Cable fire retardant coating as a special coating, it is composed of two parts: base material and flame retardant additive (aluminum hydroxide). In addition to the decorative effect of ordinary coatings and providing physical protection for cable substrates, it also needs to have special flame retardant and fire resistance. function.
The following conclusions are drawn from several experiments on the influence of aluminum hydroxide flame retardant material on the fire resistance, smoke production and anti-corrosion of fireproof coatings:
1. Aluminum hydroxide not only has a good flame retardant effect with a small amount, but also greatly improves the fire resistance 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 anti-smoke effect on the cable fire retardant coating, which can make the fire retardant coating not only do not produce thick smoke and poisonous gas when burning, but also have good flame retardant and heat insulation effect.
3. The technical route of adding aluminum hydroxide flame retardant to the cable fire retardant coating is adopted, so that when the developed cable fire retardant coating is received, the coating expands and foams well and densely, forming a dense and uniform fire insulation layer for the cable. Provide effective fire protection. However, when the addition amount of aluminum hydroxide flame retardant is 7%, the cable fire retardant coating has not only good fire resistance, but also good physical and chemical properties and clothing resistance.
