Project Background:
In order to make fiber-reinforced polymers (FRP) from combustible to non-combustible and to reduce the fire-catching and spreading threats to the buildings, the fire-retardant coating plays an important role in fire protection and decoration. Intumescent coatings are widely used due to their low cost and excellent fire resistance characteristics. However, when this kind of coating is subjected to external forces, it is prone to produce micro-cracks, resulting in poor fire resistance. The addition of self-healing fillers and flame retardants to the fire-retardant coatings is the most common and effective measure to deal with this problem, which can reduce the hazards and losses caused by fire.
Aims & Goals:
1. To develop a self-healing fire-retardant coating applied to the FRP surface with the addition of hydrocarbon-based flame retardants and self-healing fillers;
2. To study the optimum usage of fire-retardant and self-healing additive in the coatings and their interaction;
3. To carry out the research on construction technology and coating performance evaluation of fire-retardant coatings.
