Description
Technical field
The present invention relates to the anti-flaming polypropylene material technical field, specifically is a kind of collaborative expanded flame-retardant polypropylene matrix material.
Background technology
Polypropylene (PP) is a kind of general-purpose plastics, have good mechanical performance, processing characteristics, chemical resistance and electrical insulating property, light weight and nontoxic is widely used in aspects such as automobile component, structure material, household electrical appliance, electronics and wrapping material, the usage quantity rapid growth.But polypropylene also has some defectives, for example polypropylene (PP) belongs to inflammable material, and its oxygen index has only 17-18%, and forms a large amount of molten drops in the combustion processes, fire hazard is very big, has limited the use of polypropylene (PP) in fire-retardant occasion of having relatively high expectations.Therefore, be necessary very much polypropylene (PP) is carried out flame-retardant modified, enlarge the application scenario of polypropylene (PP).The method of practical economy is to add fire retardant in polypropylene (PP).Polypropylene (PP) fire retardant commonly used mainly contains three major types, is respectively metal hydroxides, halogen containing flame-retardant (especially brominated flame-retardant) and expansion type flame retardant.Metal hydroxides, as mineral compound such as aluminium hydroxide and magnesium hydroxides, have advantages such as nontoxic, pollution-free and environmental protection, but its flame retarding efficiency is very low, by needing addition big (being 50-60%wt generally speaking) just can reach required flame retardant rating, and the consistency of itself and base material is relatively poor, and a large amount of interpolations has very big infringement to the mechanical property of material, thereby has limited its application in material is flame-retardant modified.Halogen containing flame-retardant, especially bromide fire retardant have flame retardant effect preferably, be the higher series products of present flame retarding efficiency, and cost performance are more higher, use comparatively extensive, itself and antimonous oxide (Sb
2O
3) compound system after more can embody good flame retardancy, but this based flame retardant can discharge a large amount of poisonous and hazardous gas when burning, gas such as hydrogen halide, dioxin for example, article around the corrosion also cause second environmental pollution, the serious harm common people's life security and environmental safety.Along with the promulgation of rules such as " RoHS instructions " and the progressively raising of common people's environmental consciousness, the halogen containing flame-retardant system is forbidden gradually.Therefore, people begin to seek to be suitable for the fire retardant of the environmental protection of macromolecular material, efficient, Halogen, low toxicity, low cigarette.
Phosphorus-nitrogen expansion type fire retardant (IFR) is considered to the most promising environment friendly flame retardant, and has become the focus of research and development.Expansion type flame retardant (IFR) is main ignition-proof element with phosphorus-nitrogen often, can form expansion charcoal layer when burning, plays the effect that intercepts air and heat infiltration, thus the performance flame retardant efficiency.Kai Fa expansion type flame retardant is ammonium polyphosphate (APP) and tetramethylolmethane (PER) and trimeric cyanamide (MEL) three's composite product the earliest, and polyolefine is had good flame retardancy.Publication number is that the Chinese invention patent application of CN1446844A discloses " a kind of novel expansion type flame retardant ", and polyolefine is had good flame retardancy.Application number is 02124783.8 also to have adopted melamine polyphosphate and tetramethylolmethane and its ester, or tetramethylolmethane and its ester or tripentaerythritol and ester thereof are as expansion type flame retardant.Application number is 01128575.3 to have introduced with pentaerythritol phosphate and the composite preparation polyolefine of melamine phosphate halogen-free expansion fire retardant.Publication number is that the Chinese invention patent application of CN102367306A discloses " efficient halogen-free anti-inflaming polypropylene composite material and preparation method ", obtaining certain breakthrough to polyacrylic aspect flame-retardant modified, but still there is certain defective, though used PEPA is water-soluble little more a lot, still water-soluble than PER.In sum, also there is following shortcoming in present widely used expansion type flame retardant: 1, flame retarding efficiency is low, and the amount of adding fire retardant is bigger, needs to add 30% fire retardant usually; 2, relatively poor with the consistency of base material, bigger to the mechanical property infringement of base material; 3, expansion type flame retardant is water-soluble bigger, is not suitable for to contact with water for a long time.For these reasons, the range of application of expansion type flame retardant in polypropylene composite material dwindled greatly.
