In the preparation of polyurethane foam flame retardant, diisocyanate and polyol are selected as the main materials, supplemented by flame retardant components such as phosphorus, nitrogen or halogen compounds, and accompanied by an appropriate amount of foaming agent and catalyst, all materials are prepared in the container. Initially mix the polyol and flame retardant, add the diisocyanate, and stir the reaction at constant temperature. When the foaming agent encounters the action of the catalyst, gas is released to form bubbles, and a porous structure is formed. During the reaction process, the catalyst promotes the active combination of isocyanate and hydroxyl groups, quickly forming a polyurethane backbone, and the flame retardant components are uniformly embedded in the polymerization network. The final white or light-colored foam has outstanding flame retardancy. The whole process requires mastering the temperature and reaction sequence to achieve optimum viscosity, foaming degree, and flame retardant efficiency in order to form an excellent flame retardant foam.

Polyurethane foam is used in many utensils, but it is flammable in case of fire and needs to be improved urgently. Today, flame retardants are incorporated into its system, or compounds of phosphorus, nitrogen, halogen and other elements are applied to polyisocyanates or polyols to make them harmonized in the reaction. During the chemical reaction process, the flame retardant can react with hydroxyl groups or isocyanates to form a stable structure or embed a polymer backbone, and the modification performance is fundamental. When burned, it can release non-flammable gases, dilute oxygen, and form a carbon layer on the surface to isolate heat sources. There are also methods of compounding nanoparticles to enhance thermal stability, taking into account mechanics and flame retardancy, which not only ensures the lightness of the foam, but also increases its safety protection. This modification makes the polyurethane foam suitable for both industrial and civilian use, with outstanding flame retardancy.

Polyurethane foam (PU Foam) is often used in many fields such as home furnishings and buildings. However, its flammability makes fires frequent, so people use flame retardants to reduce the risk of flammation. Flame retardants used in modern chemical industries are of various kinds, such as bromine, phosphorus and inorganic, etc. Although they can achieve flame retardant effects, their toxicity has been repeatedly investigated by scholars. Occasionally, when burned, a variety of toxic gases are generated, such as hydrocyanic acid, dioxin and bromide. Suddenly inhaled, it can cause acute poisoning, damage respiratory circulation, damage liver and kidney for a long time, or risk carcinogenesis. It is refractory in the environment, causes bioaccumulation, pollutes water and soil, and also harms animals. Recently, there is also research on bio-based flame retardants, trying to balance safety and environmental protection, but its wide application is still under test. Looking at its toxicity, careful use is the way to cure the root cause.
