What is Diantimony Trioxide Formula?

Most polymer materials are flammable, and they will generate a large amount of smoke and harmful gases during the combustion process, which seriously endangers the safety of human life. Therefore, it is very meaningful to treat them with flame retardant. Diantimony Trioxide Formula is a high-efficiency additive flame retardant, which can be used independently or in combination with other flame retardants and smoke suppressants.
Diantimony Trioxide Formula 2O3, also known as antimony white, is widely used as an auxiliary flame retardant for various synthetic materials because of its excellent synergistic flame retardant synergistic effect when used in combination with halogen-based flame retardants. It is a halogen-containing polymer, which makes the application of antimony trioxide in flame-retardant polyvinyl chloride plastics special, and the application field is more common. Antimony trioxide is mainly used as a flame retardant component of synthetic materials. In addition, it can also be used as advanced glass clarifying agent for picture tubes, fluorescent lamps, etc., coatings, pigment additives (to improve water resistance, color durability and flame retardancy), heat-resistant colorants and glazes for enamel, ceramics, glass, etc. Basic dye mordants, catalysts for petrochemical and synthetic fiber industries, and raw materials for the manufacture of antimony salts.

Diantimony Trioxide Formula Uses

  1.  Flame retardant: Diantimony Trioxide Formula is one of the general flame retardant synergists.When used alone, the flame retardant effect is very small (unless the flame retardant polymer already contains halogen), and it is used with halogen. When used together with flame retardants, it can greatly improve the efficiency of halogen flame retardants. It is a general flame retardant for polyethylene, polypropylene, polyvinyl chloride, polyester, polystyrene, epoxy resin, polyurethane and other plastics. . The flame retardant mechanism of Diantimony Trioxide Formula belongs to the gas phase flame retardant mechanism. The melting point of Diantimony Trioxide Formula is 656°C and the boiling point is 1 425°C. When used alone, the flame retardant effect is not significant. The excellent synergistic effect of Diantimony Trioxide Formula is usually used together with other flame retardants to achieve the purpose of flame retardant.
  2. It can be used to manufacture Diantimony Trioxide Formula, pigment, porcelain glaze, mordant, etc.
  3. Catalyst for polyester polycondensation: catalyst grade Diantimony Trioxide Formula is an important chemical raw material. When it is used as a catalyst in the polyester polycondensation process, it is required that the catalyst not only has high purity, but also does not contain high-priced tetramine. Diantimony Trioxide Formula is also required to have high catalytic activity. The preparation method of catalyst-grade Diantimony Trioxide Formula includes the following steps: including metal antimony melting, generating antimony trioxide furnace gas and Diantimony Trioxide Formula furnace gas, cooling, crystallization, and collecting by a dust collection system to obtain an average particle size of 0.1-0.5 Catalyst grade antimony trioxide with μm, main component Sb2O3>99.9%, 325 mesh sieve residue less than 0.002%, EG transmittance>98%, whiteness greater than 99, b value less than 0.9, the method has stable quality , Large production capacity, low energy consumption, stable production operation control, strong adaptability of raw materials, and significant economic benefits.
  4. Antitumor: The study found that Diantimony Trioxide Formula (PAT), antimony trioxide and other trivalent antimony agents and As2O3
    It can also significantly inhibit the growth of leukemia cells and malignant B lymphocytes, and induce tumor cell apoptosis. Micromolar concentrations of PAT and Sb2O3 can inhibit the growth of leukemia and lymphoma cells, but have no effect on normal lymphocytes. There is no cross-resistance between trivalent ladder agents such as PAT and Sb2O3 and all-trans retinoic acid, and the concentration required to inhibit cell growth is well tolerated by the body without obvious toxic and side effects. It has certain effects in the treatment of blood system diseases. application prospects. Experiments show that Diantimony Trioxide Formula can inhibit the growth of human ovarian cancer SKOV3 cells cultured in vitro in a time- and dose-dependent manner; antimony trioxide can induce apoptosis of SKOV3 cells, which may be one of the mechanisms by which antimony trioxide inhibits cell growth. 1. Apoptosis may be related to down-regulation of bcl-2 protein expression and up-regulation of bax protein expression, which may be one of the ways to induce apoptosis of SKOV3 cells.

Production Method of Diantimony Trioxide Formula

Dry method includes metal antimony method and antimony method; wet method includes acid leaching method and antimony salt decomposition method. Dry metal antimony method (dry method). Reaction equation: Sb+O2→Sb2O3 Operation method: 700kg of 99.8% metal antimony (containing 29×10-6 sulfur) is heated to 1200℃ in a graphite furnace, and air is vented at 0.3m3/min for 5min, until the sulfur dioxide in the exhaust gas Content ≤ 5×10-6, cooled to 786 ℃, air was blown at a speed of 2m3/min for 12h, the yield of antimony white was 92.1%. Antimonite method (dry method). Reaction equation: 2Sb2S3+9O2→2Sb2O3+6SO2↑Sb2O3+3C→2Sb+3CO↑4Sb+O2→2Sb2O3 Operation method: choose high-grade antimonite containing Sb50%~60%, As0.1%, Pb0.007%, Fe0.16%, S11.42%, Al2O30.66%, CaO4.75%, MgO<0.5%, SiO28.65%, HgO0.0026%. This concentrate is mixed with iron ore (Fe50.17%) and 2% limestone (CaO>50%) accounting for 10% of the antimony concentrate, and added to the slag pool of the fuming furnace at a certain speed, and air, coal The powder mixture is used to adjust the temperature of the liquid slag and the atmosphere in the furnace to keep the temperature at about 1250 °C. The CO2/CO in the gas phase in the furnace is 4.78, 1gPO2=-8.33, and the charge is added to continuously melt. Antimony is mainly Sb2O3 and a small amount is sulfide. The form is continuously smoked into the gas phase. When purifying the flue gas, it is burned through the flue and combustion chamber, and the sulfide is converted into Sb2O3. The oxides in the flue gas are then collected in each section of the dust collection equipment. Among them, antimony oxide is collected by flue vortex, and the dust collected by electrostatic precipitator is of high purity, which can be used as antimony white. After adding the given charge, blow coal to continue melting and fuming for about 1 hour. When there is basically no white volatiles in the flue gas, the process ends and 2/3 of the slag is released. Acid leaching method (wet method). Reaction equation: Sb2S3+6HCl→2SbCl3+3H2S↑SbCl3+H2O→SbOCl+2HCl2SbOCl+2NH4OH→Sb2O3+NH4Cl+H2O Add acid-resistant leaching barrels one after another.

Diantimony Trioxide Formula Flame Retardant Formula

Antimony-containing flame retardants are mainly Diantimony Trioxide Formula (sb2o3) and antimony pentoxide. Antimony oxide is mainly used together with halogen flame retardants in the application of flame retardancy, and it is used as a synergist. It can only be used alone as a flame retardant in halogen-containing polymers such as PVC. The production of antimony oxide is mainly in my country and a few other countries, and the resources are relatively limited. Diantimony Trioxide Formula mainly produces antimony trihalide substances with wider decomposition temperature in the thermal decomposition process. Such liquid and solid Diantimony Trioxide Formula not only absorb heat during decomposition, but also have a correspondingly higher melt decomposition temperature. In addition to removing the physical flame retardant function, the Diantimony Trioxide Formula  can also react with hydrogen radicals and has a flame retardant function in the gas phase.
Diantimony Trioxide Formula flame retardant formulation. As a synergist for halogen flame retardants, the test shows that the best molar formula ratio of halogen to Diantimony Trioxide Formula is (3:1)~(4:1). Antimony halogen system is widely used in the flame retardancy of polyolefin, styrene series products, polyurethane plastic foam, epoxy resin and phenolic resin. As an independent flame retardant, halogenated polymers such as PVC are used. The flame retardant effect of different industrial grades of Diantimony Trioxide Formula is not different, but the size distribution of particle size distribution has an impact on the mechanical properties of flame retardant polymers, especially the impact strength.
