Domestic non-halogen flame retardant R & D breakthrough

On December 1st to 3rd, 2010, at the China International Fine Chemicals and Custom Chemicals Exhibition held in Shanghai, LockheedTM Flame Retardant exhibited by Liaoning Meilian Composite Materials Co., Ltd. received extensive attention. This product has changed the disadvantages of common flame retardants in the market in terms of toxicity, flame retardant effect, and added amount. The performance is comparable to or even better than that of conventional brominated flame retardants, and the price is not Half of the usual halogen-based flame retardants. At present, there are disputes over whether halogenated bromine-containing flame retardants should be used in the industry, and the flame retarding capability of traditional non-brominated flame retardants remains to be improved. Liu Qibo, vice chairman of the company, said that breakthroughs in technology have greatly improved the performance of non-brominated flame retardants. With the addition of the FireFightTM flame retardant developed by the company, the oxygen indexes of polyurethane, benzene board, cotton cloth, and filter paper were as high as 43.1%, 52.2%, 63.8%, and 72.4%, respectively, and reached the domestic advanced level. According to Liu Qibo, the company's self-developed flame-retardantTM flame retardant, through the formation of fire protection film in place to terminate the combustion process, significantly reducing the generation of smoke. At the same time the amount of 0.5% of the lock fire TM flame retardant, you can achieve a 30% of the amount of commercial products flame retardant effect. The biggest highlight is that the product contains silicon, nitrogen, phosphorus, potassium, magnesium, boron, etc., which are commonly found in the soil and fertilizer components without any toxic components. Fire-fightingTM flame retardant is a water-based flame retardant, and the penetration force Strong, the process is also very simple. In accordance with Liu Qibo's original LockFireTM theory, through the use of a closed-circuit approach to blocking fire, the optimized configuration of molecular materials is applied in small quantities to the outer layer of flammable substances, or filled into flammable substances through the route of adsorption. Into the microscopic fire protection layer, the thermal energy from the flame during the burning process homopolymerizes the molecular materials in the protective layer to form a dense and firm flame-retardant insulation layer, thereby achieving the purpose of flame-retardant. At present, the flame retardants on the domestic market are roughly divided into three types: organic halogenated, organic phosphorus and inorganic. Among them, the highest flame retardant efficiency is the organic halogen system, the price is moderate, and the market share is more than half, but the combustion fumes are large and the toxic corrosive gas is released; the organic phosphorous flame retardant has large volatility and poor thermal stability; the inorganic system is added A larger amount affects the physical and mechanical properties of the material. Relying on the lock fire TM theory, the company also independently developed the JR fire extinguishing agent series. Different from water quenching, which cannot be avoided, the JR fire extinguishing agent forms a flame-proof protective shell in the same place after the flame is extinguished, avoiding secondary combustion and being non-toxic, halogen-free and charcoal-free. New breakthroughs have been made in the research and development of non-halogen flame retardants and have been highly concerned by domestic materials and fire protection.
