Active Aluminum Oxide Powder

With the rapid development of social economy, science and technology, and 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 their internal wires and cables are widely used. In order to prevent the occurrence and development of cable fires and reduce the economic losses caused by them, fire retardant coatings are used as the flame retardant protection of cables, which is important to prevent initial fires and slow down the spread and expansion of fires It is of great significance to ensure the safety of the state and people's lives and property and promote the cause of fire control.

As a special coating, cable fire retardant coating is composed of base material and flame retardant additive (aluminum hydroxide). In addition to the decorative effect of ordinary coating and physical protection of cable substrate, it also needs to have the special function of flame retardant and fire resistance.

The following conclusions are drawn through several experiments on the influence of aluminum hydroxide flame retardant material on the fire performance, smoke production and corrosion prevention of fire retardant 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 reduces the cost.

2. when aluminum hydroxide flame retardant is added, it has obvious smoke elimination effect on the cable fire retardant coating, so that the fire retardant coating not only does not produce dense smoke and toxic gas during combustion, but also has 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 cable fire retardant coating is obtained, the coating will expand and foam well and densely, forming a dense and uniform fire insulation layer to provide effective fire protection for the cable. However, when the content 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
