Preparation method of metal boron ammonium phosphate flame retardant smoke suppressant

Abstract

The invention relates to the technical field of flame retardant smoke suppressant and a preparation method thereof, and particularly discloses a preparation method of metal boron ammonium phosphate flame retardant smoke suppressant. The preparation method comprises the following steps: step I, preparing raw materials: weighing various raw material components in parts by weight: 3 to 7 parts of boron source, 8.719 parts of metal source, 20.404 parts of ammonium source, and 10 parts of deionized water; step II, reacting: adding the weighed chemicals into a stainless steel reaction kettle with apolytetrafluoroethylene liner, and then adding the weighed deionized water into the reaction kettle; step III, cooling at room temperature: placing the reaction kettle in a drying oven, setting the temperature of the drying oven at 100 to 220 DEG C, reacting for 1 to 5 days at a constant temperature, and cooling at the room temperature; and step IV, washing, suction filtering and drying: repeatedly washing by using the deionized water, removing the unreacted excessive boric acid, suction filtering, and drying, thus obtaining the metal boron ammonium phosphate flame retardant smoke suppressant.By adopting the flame retardant smoke suppressant, the weaknesses of the prior art are overcome, the obtained product is high in purity and good in dispersity, no acid and alkali waste solution is discharged in the reaction process, and the energy consumption is small.

Description

technical field

[0001] The invention relates to the technical field of flame retardant and smoke suppressant and its preparation, in particular to a preparation method of metal borophosphate ammonium salt flame retardant and smoke suppressant. Background technique

[0002] Wood-plastic composite material is a kind of wood fiber material (WF) in the form of fiber and powder as filling or reinforcing material, with thermoplastic as matrix material, adding various additives through extrusion, hot pressing, molding or injection molding, etc. A new type of composite material made by combining various processing methods. Commonly used thermoplastic substrates include polyethylene (PE), polypropylene (PP), polystyrene (PS) and polyvinyl chloride (PVC).

[0003] Wood-plastic composite materials without fire-resistant and flame-retardant treatment are easy to burn, and have a large calorific value of combustion. At the same time, wood-plastic composite materials using PS and PVC pla...
