Description
Technical field
The present invention relates to fire proofing, and in particular to a kind of polypropylene composite of halogen-free flameproof and preparation method thereof.
Background technology
At present, the domestic main flow fire proofing of China is bromine series flame retardant material.But, with to environmental requirement more and more higher, this
Plant bromine series flame retardant material and easily produce pollution because of it, face the destiny that will be eliminated.So, it is more next according to new environmental requirement
More people begin one's study bittern-free flame-proof material, but China's country's bittern-free flame-proof material all prices are high, and preparation technology is multiple
It is miscellaneous, it is impossible to large-scale industrial application.
EUROPEAN PATENT OFFICE's EP0735119A1 open files disclose a kind of P-N type fire retardant for polyethylene, the P-N type
Addition of the fire retardant in polyethylene (PE) is 35%, and limited oxygen index (LOI) reaches V-0 levels up to 35, UL-94.But
This based flame retardant flame retardant effect in the fire proofing constituted with polyethylene is undesirable, on the other hand this based flame retardant moisture-sensitive itself
And cause the electric property of fire proofing to decline.Have for the carbon forming agent PER (pentaerythrite) in traditional IFR (fire retardant)
Easily migration, the shortcomings of work in-process can generate phosphate with APP (polyphosphoric acid amine), Liu Jun et al. (《Polymer material science with
Engineering》, 1999,15 (1)：73-79) have studied nitrogenous pyrrolotriazine derivatives for carbon forming agent to PP (polypropylene) fire resistance
Impact, when APP and pyrrolotriazine derivatives are 5：When 1, the LOI values of PP are up to 33.5.Ou Yuxiang et al. (《Chemical industry is in progress》,
2004,23 (8)：MPP/PER/APP ternarys IFR 857-860) be have studied to the fire-retardant of PP (polypropylene), MPP is worked as in discovery
When (Poly-o-aminophenol film) ternary IFR addition is 25%, the anti-flammability of PP reaches UL94V-0 levels, and LOI is 30.7, with three
First IFR consumptions increase, and flame retarding efficiency (EFF) is improved, and up to 30 or so.The addition of ternary IFR reduces the starting of PP
Decomposition temperature, improves in charring rate, but the thermal degradation volatile products of fire-retardant PP in addition to having the micromolecular compounds such as ammonia gas and water,
Also melamine is released, and easily causes human injury, is caused environment pollution.
