    In we of daily in the often can heard appalling of fire message, fire reasons many, like wire short-circuit raised fire, ceiling fire raised fire, cigarette not out raised fire, curtains fire raised fire, outside wall insulation board fire raised fire and so on, most when is because by with material no strictly of according to related of fire security standard do is good of flame retardant, a small flames on fast of raised has fire, no to people time to escape, Was a lot of hot burning to death or by the amount of poisonous gas suffocation, lead to disaster. Scientists compare add TCEP flame retardant and do not add the TCEP flame retardant material Burns concluded:

  • Phosphorus-containing flame retardant...


    Varieties of organic phosphorus in phosphorus flame retardants are mostly oily, add them easily in polymer processing, usually in polyurethane foam, soft PVC, transformer oil, cellulose resins, used in natural and synthetic rubber. Phosphorus flame retardant is mainly divided into inorganic phosphorus and organic phosphorus flame retardants. The main products of inorganic flame retardant containing phosphorus flame retardant of red phosphorus, ammonium phosphate and ammonium Polyphosphate, etc. Advantages are good stability, not of inorganic phosphorus and no corrosive gases, lasting effect and low toxicity. Among them, the flame retardant of red phosphorus flame retardant is obviously better than phosphate esters.

    TCPP flame retardant as a fire-fighting tools, plays an important role in our daily lives, it widely used in electronics, home furnishing, children's toys, building materials, vehicles, and other fields, no exaggeration to say that, each place it at our fingertips, escort for our modern life. Because it's there, we can prepare, fire is not burning. However, the existence of such an important, but did not get a correct understanding of, and forgotten in a corner, or being misunderstood, expulsion. I think people are misunderstanding is no scientific knowledge and understanding, greater is the fear people have.

  • Triethyl phosphate related introduction


    Triethyl phosphate name: triethyl phosphate English name: Triethyl phosphate alias name: triethyl phosphate triethyl phosphate triethoxy phosphorus more aliases: molecular formula: C6H15O4P, molecular weight: 182.07 Properties: triethyl phosphate in fairly high doses produce narcotic-like phenomenon and visible muscles. On the inhibition of brain acetylcholinesterase. On the surface of the skin and respiratory tract irritant. Oral in rat LD50800mg/kg. manufacturing equipment should be sealed to prevent leakage. Operators should wear protective equipment. Phosphorus trichloride, ethanol and sodium preparation ① preparation of chlorinated trisodium phosphate acid diethyl ester: phosphorus trichloride and toluene mixture, stirred by adding anhydrous alcohol, temperature control 30-40 ℃ after the mix 0.5h, reaction of diethyl phosphite. Then drops into the Sulfuryl chloride (SOCl2), and temperatures of 30-40 ° c vacuum to remove excess thionyl dichloride, chloro-diethyl phosphate residues. [2] second, the synthesis of triethyl phosphate: join the alcoholic solution of sodium ethoxide reactor, while stirring add chlorinated phosphate ester, temperatures of 70 ℃, ethanol and sodium acetate to mediate pH value to 7-8, adds stirring 4H. Then add cold water, mix then add toluene and continue stirring for a while, rest for hierarchical extraction grease the upper, dry carbonate anhydrous, filtered reclaim toluene followed by vacuum distillation, collect 72-88/0.4-0.667MPa product, to obtain the finished product. [2] (2) with Phosphorus oxychloride and alcohol as raw material, synthesis of two steps of: 100mL (1.07mol) the inputs of phosphorus oxychloride in the 250mL of four flasks with Blender, ice brine cooled to below 15 ° c under vacuum, and then add 92mL (1.60mol) ethanol. In another 1000mL of four flasks with a blender, put 550mL (9.63mol) ethanol, under the atmospheric pressure dropped the product cooling with ice water and salt water, guaranteed response to humidity is less than 15 ° c the reaction mixture in ethanol recovery 0.098MPa under high vacuum. After distillation humidity below 55 degrees will reclaim control applied to the esterification of ethanol 2 and neutralizing the remaining liquid alkaline product, the pH value of 6-7, extraction, distillation, finished 165.05g. Parameters: Phosphorus oxychloride: ethanol =1:9 (MOL), the response to humidity 15 response time is 1.5h; yield about 82%.
  • chloride propyl three phosphate ester...


    Phosphoric acid (chloride-propyl) tri-: name: TRIS (Dichloro-propyl) phosphate, English name: TRIS (1,3-dichloropropyl) phosphate,CAS number: 40120-74-9, molecular formula: C9H15Cl6O4P, molecular weight: molecular formula is C9H15Cl6O4P 430.9048, 430.9048,CAS registration number 40120-74-9 molecular weight, a common catalysts and additives. Phosphate (two chlorine c base) three ester is combined has p and chlorine of phosphate ester, thus on plastic, and rubber products has good of flame retardant and increased plastic performance, phosphate (two chlorine c base) three Ester in both at home and abroad has as flame retardant agent was widely for PVC, and polyurethane soft, and hard bubble, and acetate cellulose, and nitro cellulose paint, and b base fiber paint and the difficult burning rubber, and rubber transport with in the. Products available with self-extinguishing, weather resistance, cold resistance, anti-static, soft to the touch, adding 5~10. Rigid polyurethane foam oxygen index (LOI) up to 26. Also can be used as extreme pressure additive of lubricating oil, gas paint additive, hot coolant and metal magnesium. Use a galvanized drum packaging net weight 250 kg. Storage temperatures under 5 ° c between ~38, when stored for a long time, not exceeding 35 ℃, and air dry. Used for strips, massive flame retardant foam production. It is a low-cost flame retardant and good stability. Phosphoric acid (chloride-propyl) three esters are widely used in rubber and PVC plastic flame-retardant conveyor belt, leather, agricultural film, flooring materials, cables, flame retardant neoprene, nitrile rubber, synthetic rubber plasticizers, flame retardants of epoxy resin.

    With the increasing people's awareness of environmental protection, safety, health, fire and find a balance between environmental protection, is an important node of the future development of flame retardant. Flame retardant manufacturers all over the world began to use environmentally friendly flame retardant as research and development and application focus. Flame retardants classified according to valid elements, can be divided into phosphorus, chlorine, and bromine base, aluminum, antimony and boron-based flame retardant agent. Effective elements based on flame retardant and flame retardants can be classified into non-halogen flame retardant, brominated flame retardant agent, synergistic flame retardant and flame retardant halogen-phosphorus, these environmentally friendly flame retardant has broad application prospects. Environmentally friendly flame retardants: halogen-free flame retardant Halogen free, low smoke, low toxicity of environmental flame retardant has been the pursuit of the goal, in recent years the global flame retardant supply and application of flame retardant halogen shown high enthusiasm, on halogen-free flame retardant and flame retardant materials development also invested a great deal of power. According to analysis, the main variety of halogen-free flame retardant agent for phosphorus flame retardant and inorganic hydrate. The former mainly consists of red phosphorus flame retardant, inorganic phosphate ammonium Polyphosphate (app), ammonium dihydrogen phosphate, diammonium phosphate, phosphate, organic phosphorus, halogen-free phosphate. Which mainly consists of magnesium hydroxide, aluminum hydroxide, modification of materials such as hydrotalcite and so on. Ammonium Polyphosphate, water of talc for the series of eco-friendly and good market prospects for product. Flame retardant agent: brominated flame retardants
