“…Therefore, in recent years, flame retardants are incorporated in polyurethane (PU) to improve its flame retardancy [4][5][6]. Both, additive and reactive flame retardants are incorporated to impart flame retardant properties to the polyurethanes [7][8][9][10]. Various additive flame retardants such as boric compounds [11], aluminium polyphosphate, triphenyl phosphate [12], triethyl phosphate [13], layered silicate [14] expandable graphite [15], melamine and its derivatives [16] were extensively used in the past to improve its flame retardancy.…”

“…A variety of materials have been developed as flame retardants included epoxy and polyurethane to improve their fire resistance properties (Tirri et al 2012; Song et al 2005; Zhang et al 2014). Flame retardancy in coating materials is incorporated either by an additive or reactive approach (Bhatnagar and Vergnaud 1981; El-Wahab et al 2012; Borisov et al 1988). The mode of action for various flame-retardant systems was performed by five different mechanisms to slow down the rate of fire as shown in Figure 4.…”

Flame retardants mitigate the threat of fire from inherently flammable wood and wood products responsible for sustaining a high standard of living. Wood is one of the aesthetically pleasing, highly sustainable as well as eco-friendly materials. It is not only an integral part of structures, but also the main source of home appliances, furniture, industrial applications, and offices all over the world. The coating provides protection to wood materials against outdoor weathering, photochemical degradation, and fire. Therefore, to minimize the degradation of wood for the increasing long life and survival ability, various coatings were synthesized and applied to enhance their performance for the wood application. This review provides a historical overview that leads to the structural properties of wood and the most promising surface treatments that will help pave the way for developing more effective and non-intrusive flame retardants in the future.

“…Therefore, improving the flame retardant properties of FPUF products has become the research field of many scholars. In recent years, additive flame retardants or reactive flame retardants have been added to impart flame retardant properties to polyurethane foam [10][11][12][13]. However, the addition of flame retardants might cause some problems, such as phase separation caused by high load, loss of uniformity, high component viscosity, etc.…”

Flexible polyurethane foam (FPUF) is a flammable synthetic polymer. In the foam production process, large amount of heat would be released from the chemical reactions of raw materials, which would even cause spontaneous combustion of foam. Thus, it would be meaningful to study the heat generation mechanisms and provide some measures to decrease heat production during FPUF production. This paper implemented FPUF production and temperature monitoring experiments to study the influence of different raw material dosages on the the FPUF production temperature. Meanwhile, FTIR analysis experiments were implemented to study the reason of production temperature changes at the influence of different raw material dosages. From the results, FPUF production temperature is closely related to the physical changes (such as evaporation, volume change, mass change) and chemical changes (such as foaming reaction, gelling reaction, catalytic reaction) of the foaming process. Insufficient polyol will lead to a significant increase in FPUF production temperature, which is a bigger potential safety hazard in FPUF production than dosage misuse of other raw materials. Meanwhile, replace part of polyether polyol with polymer polyol and replace part of water with methylene chloride in the FPUF formula can further effectively reduce the foam production temperature, and keep the foam quality simultaneously.
