( Industry news] 【 The latest environmental dynamic 】 American children supplies limited with antimony trioxide flame retardant qybee P in the near future, the United States congress put forward a new proposal 'in children and firefighters protection act, limiting use in children's products or upholstered furniture ten bromine biphenyl ether, three ( Ethyl chloride) Phosphate ester, phosphate three ( Propyl chloride) Esters, tetrabromobisphenol A, hexabromocyclododecane, chlorinated paraffin, antimony trioxide flame retardant masterbatch such as flame retardant. The proposed change is very big, demanding, limit children's products or upholstered furniture ( Diaper pad, portable crib mattress, pajamas, the nap mat, nursing pillows, etc. ) Any part of the are not contain more than PPM above including antimony trioxide flame retardant masterbatch in the column of flame retardant, the new rules are expected to take effect in July. The United States is an important trade port of China children's products. Therefore, remind relevant enterprises: one, to keep a close watch on flame retardant technology regulations, dynamic, flame retardant regulations in strict accordance with the requirements of design and manufacture products, or choose to use more safe alternatie to flame retardant; Two, we will strictly control the quality of the product, be mastered all kinds of auxiliary production source and component, beware of banned substances in the process of production is not reasonable to add; Three, to strengthen the contact with inspection supervision department and the third party testing laboratory, to improve the quality of each batch product testing, beware of defective products into the market. The physical and chemical properties of antimony trioxide white crystalline powder. After the warm yellow, cold white. No smell. Melting point ℃. Boiling point ℃. High vacuum heating and the ℃ sublimation. Soluble in sodium hydroxide solution, heat tartaric acid solution, hydrogen tartrate salt solution and sodium sulfide solution, slightly soluble in water, dilute nitric acid and dilute sulphuric acid. Relative density. 。 The median lethal dose ( In rats, through the mouth)> G/kG。 Have a carcinogenic potential. The preparation methods by stibnite ( Sb? 年代? ) Calcination oxidation products Sb? O? , for purification to remove arsenic and iron, and then to carbon reduction into metal antimony, further purification of smelting and reoxidation pure Sb? O? 。 Used for catalyst, mordant, fabrics, paper, plastic, flame retardant, glass decolorizing agent; For the preparation of antimony potassium tartrate, glaze, fire prevention agent; Manufacturing lead softener. Antimony trioxide is the first application of flame retardant, suitable for epoxy resin, polyurethane, chloroprene rubber, polystyrene, polyvinyl chloride, polyester, etc, when used alone dosage, flame retardant effect is poor, Unless the solid flame retardant containing halogen When with the halogen compound ( R。 HX) And has a good synergistic effect, when the flame retardant effect is improved obviously. Antimony trioxide belongs to add flame retardant agent, often with other flame retardants and smoke elimination agent and use, can produce synergies between components. Antimony trioxide in the early part of the combustion, first is melting, the material form a protective film from the air, through internal endothermic reaction, reduce the combustion temperature. Under high temperature condition of antimony trioxide are vaporized and dilute the oxygen concentration in the air, and flame retardant effect.
