POLYMER TYPE PHOSPHOR-CONTAINING FLAME RETARDANT, PREPARATION METHOD AND APPLICATION THEREOF

摘要

Disclosed are a polymer type phosphor-containing flame retardant, preparation method and application thereof, which belong to the field of chemical materials. The polymer type phosphor-containing flame retardant PNX is a compound shown in formula (1), wherein n is an integer of 5~8 and the molecular weight of the flame retardant is between 900 and 1400. The method for preparing the flame retardant PNX is as follows: reacting phosphorus oxychloride with ethylene glycol in a nitrogen environment through a chemical reaction shown in the reaction formula (1) to obtain a compound (2), then reacting the compound (2) with anhydrous ethanol through a chemical reaction shown in reaction formula (2) under the action of a catalyst aluminum chloride to produce the flame retardant PNX. The flame retardant PNX belongs to a halogen-free, phosphorous type flame retardant. It coincides with the national concept of green-environmentally-friendly development. The content of phosphor is as high as 18%~20%, and the flame retardant properties are excellent.
