While technology thrives in many new directions, it is also important to find the optimal measures to protect human assets from natural or unnatural derived misfortunes. For example, forest fires, caused by climate change and the temperature rise, could penetrate hundreds of houses and damaged properties. Therefore, it is a need to develop effective protective measures that help the population to keep their assets unharmed. Fire protective systems, e.g., intumescent paints, are a suitable solution for different materials and structures. However, there is still a lack of development on their application over pretreated biomaterials, such as wood.
The present project consists of the evaluation of the effect caused by the addition of intumescent paint on pretreated woods. The effect was analyzed in two different blocks of wood, plywood, and spruce. The experiments were carried out for untreated and pretreated materials, understanding the effect of the different pretreatments and conditions applied. The addition of primer and a different number of paint layers, as well as variation of heat flux, were studied. Characterization of the char formed during the heating was performed to reveal porosity and pore size distribution. Lastly, thermogravimetric analyses (TGA) were carried out to determine the thermal degradation of the intumescent paint.
