Problems solved by technology

However, both single-component and three-component intumescent flame retardants have the following disadvantages: one is that single-component salts are mainly synthesized in water, and the yield is low; the other is that intumescent flame retardants The relative molecular weight of the main component of the flame retardant material is low, incompatible with the matrix during processing, easy to migrate or precipitate, resulting in a decrease in the mechanical properties of the flame retardant material, and the flame retardant effect cannot be achieved
In order to solve these problems, bis(2,6,7-trioxo-1-phosphorus-bicyclo[2.2.2]octane-1-oxymethyl)phosphate 4,4'-diamino Diphenylmethane salt etc., although effect is remarkable, because its production cost is high, synthesis process is complicated and by-product is many and limits its use

Abstract

The invention belongs to the technical field of halogen-free intumescent flame-retardant materials and discloses a multifunctional flame-retardant masterbatch, a flame-retardant masterbatch based phosphorus-nitrogen intumescent flame-retardant material and a preparation method thereof. The multifunctional flame-retardant masterbatch is prepared from the following ingredients: matrix resin, a phosphate compound, a multi-carbon polyhydroxylated compound, a nitrogenous multi-carbon compound and a coupling agent. The multifunctional flame-retardant masterbatch provided by the invention integrates an acid source, a carbon source and a gas source and exerts multiple functions such as coating a surface, lowering hygroscopicity, improving the compatibility between the masterbatch and a base material, dispersing, and retarding flaming. The multifunctional flame-retardant masterbatch provided by the invention contains a phosphate derivative, so that the flame-retardant material can achieve low smoke, no driopping and flame-retardant rank V-0; compared with the existing intumescent flame retardants, the intumescent flame-retardant material has the advantages that the precipitation resistance and moisture resistance are superior to those of the existing intumescent flame retardants, and the use level is obviously reduced (the addition level is 22% to 28%) in case of achieving the same flame-retardant effect, so that the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of halogen-free intumescent flame-retardant materials, and in particular relates to a multifunctional flame-retardant masterbatch, a phosphorus-nitrogen intumescent flame-retardant material based thereon, and a manufacturing method thereof. Background technique [0002] The use of halogenated flame retardants to improve the flammability of polymer materials has a small amount of addition and a significant flame retardant effect. Halogen-based flame retardant systems play a flame-retardant role mainly by degrading and producing hydrogen halide gas or halides, but these compounds increase the generation of toxic and shielding gases in fires, causing great environmental pollution and harm to human health. Damage, like other toxic heavy metals (such as lead, cadmium, mercury, hexavalent chromium, etc.), the European Union (European Union) decided to completely ban them on July 1, 2006 in the Restriction of the U...
