Description
Technical field
The present invention relates to a kind of macromolecular material and preparation method thereof, particularly relate to a kind of halogen-free anti-flaming polypropylene material and preparation method thereof.
Background technology
The fire-retardant evolution to halogen-free flameproof of fire-retardant, the low halogen of Halogen has been experienced in the fire-retardant research of macromolecular material, because the plastics that contain halogen flame can produce a large amount of cigarettes and poisonous, mordant gas in the time burning, respiratory tract to human body and other organ work the mischief, even cause and suffocate and life-threatening, industrially developed country has started to ban use of the plastics that contain halogen flame at present.Inorganic combustion inhibitor is owing to having good thermostability, non-volatile, nontoxic corrosion-free, does not cause secondary pollution in the time of burning, and its development must will become the main flow of fire retardant with exploitation.
Composite flame retardant system, mainly according to the synergy between different flame retardant, fire retardant is carried out to preferably combination to reach the system that improves fire-retardant effect object, use composite flame-retardant agent can reduce single amount of flame-retardant agent, and the advantage that effectively composite flame-retardant agent system can comprehensive several fire retardants.
Inorganic combustion inhibitor mainly contains magnesium hydroxide, aluminium hydroxide, Sb system fire retardant, inorganic phosphorus flame retardant, boron flame retardant etc.Wherein magnesium hydroxide and aluminium hydroxide are the fire retardants of output maximum in inorganic combustion inhibitor.
The decomposition temperature of magnesium hydroxide is between 340～490 DEG C, caloric receptivity is 782.9J/g, Heat stability is good, there is good fire-retardant and smoke effect, be particularly suitable for the superpolymer such as the PP that processing temperature is higher flame-retardant modified, aspect harm in reduction to environment and material safe handling, more can meet the requirement of regulations, also make flame retardant plastics be easier to regeneration simultaneously.And Mg (OH)
2raw material sources are abundant, and cheap, the fire retardant that uses it as PP has higher economic benefit.
The decomposition temperature of aluminium hydroxide is between 200～210 DEG C, caloric receptivity is 1967.8J/g, to integrate fire-retardant, press down cigarette, fill the fire retardant of three large functions, it has advantages of under nontoxic, corrosion-free, good stability, non-volatile, high temperature and does not produce toxic gas, and cheap, wide material sources.The temperature that aluminium hydroxide starts to decompose is in polymkeric substance and becomes liquid phase cracking process from condensed phase, therefore the rising that suppresses the early stage temperature of polymer materials is worked.
Zinc borate is that a kind of solid inorganic of excellent property adds fire retardant, tool is well fire-retardant and press down cigarette effect, in the time adding the goods chance fire of low hydration zinc borate, the contained crystal water Yin Wendu of zinc borate raises and decomposes and remove, and oxygen and other inflammable gass of absorbing in heat diluent air stop burning.
Ammonium polyphosphate is a kind of important Halogen phosphorus flame retardant, in its molecule, contain phosphorus simultaneously, two kinds of elements of nitrogen, in fire-retardant process, phosphorus, nitrogen have cooperative flame retardant effect, thereby flame retardant effect is better than single phosphonium flame retardant or single containing nitrogen combustion inhibitor, and its phosphorus content and nitrogen content high, Heat stability is good, product is bordering on neutrality also can be mixed with other fire retardants, low price simultaneously, and toxicity is lower, use the advantages such as comparatively safe, be widely used.
Polypropylene (PP) is the macromolecular material that a kind of output is large and performance is comparatively excellent, has excellent mechanical property, the good feature such as insulativity and chemical proofing.But the oxygen index of PP is only 17～18%, easily burn and be prone to molten drop and curtain coating phenomenon on fire, a large amount of unsaturated gas producing in combustion processes can aggravate propagation of flame, further applies thereby limited it.Therefore, develop high performance halogen-free flame retardants for the preparation of the halogen-free flame retardant polypropylene composite material that has good flame retardant properties and mechanical property concurrently, there is very important practical significance and huge economic worth.
Summary of the invention
The object of the present invention is to provide a kind of halogen-free anti-flaming polypropylene material and preparation method thereof.The method adopts the composite mode of multiple inorganic combustion inhibitor, by from the gentle fire retardation of bringing into play when identical of condensed phase to improve the flame retardant properties of polypropylene composite material.
The object of the invention is to be achieved through the following technical solutions:
