| titleOfInvention | The preparation method of the anhydrous expansion type flame retardant of N-P halogen-free |
| abstract | The invention discloses the preparation method of the anhydrous expansion type flame retardant of a kind of N-P halogen-free, solid flame retardant is made up of strong phosphoric acid, polyvalent alcohol, trimeric cyanamide, citric acid, inferior sodium phosphate, Vanadium Pentoxide in FLAKES, and through esterification, salt-forming reaction is prepared from.The overall preparation process of the present invention is anhydrous, without any solvent, can avoid with an organic solvent to the harm of environment or the corrosion to equipment like this, the phosphoric acid ester melamine salt that can avoid the formation of again meets the hydrolysis that water causes salt, and product expansion character is affected.After expanding, outside surface presents smooth uniform; continuous densification, firm carbon-coating structure; this structure can play the effect of heat insulation oxygen barrier in combustion; carbon-coating is inner in cellular structures; evenly void-size distribution, play heat insulation effect better, firmly solid; carbon-coating can not be destroyed by air-flow in combustion, thus can play the effect of sustainable protection to base material. |
