Abstract

The invention discloses an ammonium polyphosphate based phosphorus-nitrogen synergistic halogen-free flame-retardant material and a preparation method thereof. The flame-retardant material is prepared from, by weight, 25-30 parts of homo-polypropylene, 50-60 parts of co-polypropylene, 10-15 parts of ammonium polyphosphate, 3-7 parts of pentaerythritol and 1-3 parts of a synergistic flame retardant. Compared with a phosphorus flame-retardant material in the prior art, the ammonium polyphosphate based phosphorus-nitrogen synergistic halogen-free flame-retardant material which reaches V0 level in combustion has advantages of excellent flame retardation effects, low smoke, freeness of halogen, high dispersity and low influences on mechanical properties.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to an ammonium polyphosphate-based phosphorus nitrogen synergistic halogen-free flame-retardant material and a preparation method thereof. Background technique [0002] Halogen-free, low-smoke, low-toxicity, high-efficiency environmentally friendly flame retardant materials have always been the goal pursued by people. Phosphorus-based flame retardants mainly include red phosphorus flame retardants, inorganic phosphorus-based APP, ammonium dihydrogen phosphate, dihydrogen phosphate Ammonium, phosphoric acid ester, etc., organophosphorus non-halogen phosphoric acid ester, etc. [0003] For the phosphorus-based flame-retardant materials in the prior art, there is still room for improvement in the flame-retardant effect. In addition, in terms of the impact on the mechanical properties, there is also room for improvement to further reduce the impact on the mechanical ...
