Development of measures to increase the resistance of composite materials to heat flow to prevent fires and environmental emergencies
The woodworking industry is one of the most waste-forming, while these wastes are secondary wood resources, but at the same time they have a significant disadvantage: they belong to the group of combustibility flammable materials. The work is devoted to the assessment of the behavior of samples of newly proposed finishing materials for interior work, during their thermal decomposition in order to reduce their fire hazard. Parameters were continuously measured: linearly varying sample heating temperature, sample mass reduction, and exo- and endo-thermal effects accompanying sample heating. The tests were carried out using a synchronous thermal analysis analyzer STA 449 F3 Jupiter manufactured by NETZSCH. As a result of the tests, it is recommended to increase the mass fraction of the inert component of the composite (talc) to reduce the flammability of composite samples based on cellulose. To increase the overall thermal stability, it is recommended to use tetrabornoxyl sodium.
