Fire proof paint composition {Fire Proof Paint Composition}

The present invention relates to a non-combustible paint composition, and more particularly, to a non-combustible paint composition having excellent heat insulating performance as well as non-combustible performance, adhesion to a surface to be painted and antibacterial performance.

In the event of a fire, the need for non-combustible interior materials that can be applied to buildings to minimize the emission of toxic gases that cause casualties and strengthen fire safety laws has emerged. In particular, with the emphasis on non-combustible performance of building materials inside/outside, the obligation to use non-combustible paints is increasing in new constructions such as subways, public buildings, and government offices.

Therefore, there is a need for a paint that has excellent workability and on-site productivity while maintaining incombustibility and excellent adhesion to the widely used Al-Sheet.

On the other hand, in order to suppress the increase in costs due to heating and cooling and overcome environmental problems, recent buildings have been using various types of insulation materials such as Styrofoam and urethane foam and using double-glazed windows for windows in order to maintain compulsory heating and cooling facilities and realize an optimal living environment. are installing However, it is not an inefficient and economical method because it is accompanied by the cumbersome process, the volume occupied by the insulation material, and enormous cost. Moreover, there is a problem in that the thickness of the insulator becomes thicker and the weight increases in order to increase the energy utilization efficiency during heating and cooling because the heat blocking effect is not certain with the existing insulator alone.

Therefore, attempts have been made to minimize the accumulation and absorption of heat by using coating materials with relatively low thickness and light weight, but urethane waterproof paint, which has been mainly used as an exterior coating material for buildings, is difficult in construction, lifting of the coating film, and external heat. The blocking effect is low, so-called cool-roof paint, which is a conventional heat-insulating paint, has an effect of lowering the indoor temperature, but it does not meet expectations, and TiO ₂ , which is an excessive amount of white pigment in the paint, and similar light substances, etc. It is necessary to improve in terms of life extension and energy saving of buildings due to the occurrence of cracks and deterioration of adhesive strength due to the inclusion of .
