Study On The Production Process And Flame Retardant Properties Of DMMP

Flame retardants are given flammable polymer flame-retardant additives, flame retardants in all kinds of additives to further enhance the status due to the rapid development of polymer materials. Flame retardant, high efficiency, and low prices halogen flame retardants to be a rapid development in the1880s, but the halogen flame retardant will release toxic fumes, does not meet the requirements of environmental protection. Currently associated with flame retardant requirements stringent and relevant state laws and regulations promulgated by organophosphorus flame retardants boomed. Dimethyl Methyl Phosphonate (DMMP) in one of the organic phosphorus flame retardant, and is currently on the market is excellent in flame retardant properties of the flame retardant product. DMMP is a halogen-free, low-viscosity liquid additive-type flame retardant, a phosphorus content of up to25%, excellent flame-retardant properties. DMMP high phosphorus content, flame retardants add less, use more convenient, at the same time the DMMP there has the dual role of reducing viscosity and flame retardant.The papers include an overview of the global flame retardant market, the predicted flame retardant market trends commonly used flame retardant market made a comparison of the advantages and disadvantages of. From phosphorus to the phosphorus trichloride, in the synthesis of trimethyl phosphite by phosphorus trichloride, and finally by trimethyl phosphite synthesis DMMP production process. The entire production line process, major equipment, plant layout diagram, material balance and heat balance, production safety and environmental protection. To the field factory internship, basic grasp and understanding of the DMMP Production, study currently the latest production technology. Aspen Plus simulation intermittent production and continuous production of the phosphorus trichloride, concluded:continuous production can improve product yield and reduce the operation of the production process and frequent switching, can take full advantage of the heat of reaction, and reduce energy consumption. Made factory investment planning, get DMMP conclusion of the chemical project is worth the investment. In addition, DMMP retardant properties, the first through TCEP, TCPP, tetrabromoethane, pentabromodiphenyl ether flame retardant properties compared to experiment, clear the DMMP retardant excellent performance. Analysis of the Dimethyl Methyl Phosphonate this product economy, and predict the prospect of DMMP.
