Abstract

The invention relates to the technical field of flame-retardant synergists, and discloses a production and preparation method of a red phosphorus flame-retardant synergist. The method comprises the following steps: preparing the following raw materials in parts by weight: 10-20 parts of red phosphorus, 2-3 parts of ammonium polyphosphate, 3-4 parts of ammonium dihydrogen phosphate, 5-8 parts of magnesium hydroxide, 1-3 parts of zinc borate, 20-30 parts of dolomite powder, 2-4 parts of dicyandiamide, 1-3 parts of melamine cyanuric acid hydrochloride, 0.5-1 part of trioctyl phosphate and 3-5 parts of tricresyl phosphate; and putting the prepared raw materials into a stirrer, adding 50 parts of distilled water, fully stirring, putting into a calcining furnace body, calcining for 6 hours, putting into a crusher, screening, finally putting into a stirring barrel, pouring 50 parts of a resin solution, stirring, and drying. According to the prepared red phosphorus flame-retardant synergist, a layer of cured resin can cover the outer parts of flame retardant particles, so that moisture in air can be effectively prevented from entering the flame retardant, the condition of oxidation caused by moisture is avoided, and a good moisture-proof effect is achieved.

Description

technical field [0001] The invention relates to the technical field of flame retardant synergists, in particular to a production and preparation method of a red phosphorus flame retardant synergist. Background technique [0002] Flame retardant synergists are mainly nitrogen-based, phosphorus-based compounds and metal hydroxides, including nitrogen-phosphorus expansion systems and graphite expansion systems. The compounds of this type of system are non-volatile and do not produce corrosive gases when burned. Known as a pollution-free flame retardant, it is a development trend. [0003] Red phosphorus flame retardant synergist is a kind of flame retardant synergist, which belongs to the series of inorganic flame retardants. Red phosphorus is one of the main components of flame retardant synergist. Red phosphorus is prone to moisture absorption during storage. , The problem of easy oxidation reduces the use effect of red phosphorus flame retardant synergist. Contents of the...
