Description
Technical field
The present invention relates to a kind of non-bittern type flame-retarded resin compositions, said composition demonstrates the flame retardant resistance that is parity with or superiority over currently available products, and material price is cheap, and has excellent tensile strength, can not produce halogen gas during burning yet, therefore have excellent security for environment.
Background technology
For flame-retardant formulations, the various technology of metal hydroxidess such as magnesium hydroxide have been proposed to use in recent years as the polyolefin resin of the isolator of electric wire, cable and sheet.
Magnesium hydroxide has advantages such as toxicity is low, the amount of being fuming is few, corrodibility is low, has given play to fire retardation by discharging crystal water during burning, still, its flame retardant resistance is not strong, with respect to 100 weight part new LDPE (film grade)s, cooperate 100 weight parts of equivalent, the oxygen consumption index value also has only about 25.When adding magnesium hydroxide and organosilicon in polyolefine, flame retardant resistance demonstrates and increases substantially.
At present, as the employed magnesium hydroxide of the fire retardant that is used for thermoplastic resin be in the magnesium salt solution that seawater and bittern contain, add alkali such as NaOH, unslaked lime after, to implant as the kind grain of nuclear, make crystalline growth, the method for crystalline growth is synthesized, particularly when synthetic, in alkaline solution, pressurize, heat, then can obtain the crystallization of hexagonal system, under hot conditions, can make the crystallization of tabular hexagonal system.The magnesium hydroxide that the magnesium hydroxide particle diameter of being produced by this method is thin, particle diameter is the magnesium hydroxide of 2～10 μ m and particle diameter is 0.01～1.99 μ m exists with 20: 80～0.1: 99.9 ratio usually.
But,, cooperate the polyolefin blend of this magnesium hydroxide to compare and exist the problem of selling at exorbitant prices with the polyvinyl chloride-base compound because such magnesium hydroxide costs an arm and a leg.In addition, by with organosilyl and usefulness, though improved flame retardant resistance owing to cooperate organosilicon then to exist the problem that reduces tensile strength.
For this reason, recently, owing to the natural product low price of natural rock after pulverization process begins to be used, but therefore the impurity difference has the situation that influences complexing compositions character owing to produce the place difference of natural rock.In addition, because under some occasion, the arsenic that contains tens of ppm will produce safety issue, particularly sneaks under the situation of asbestiform fiber, had better not use.
The synthetics magnesium hydroxide crystallizes into the elongated except above-mentioned, the known method that magnesium oxide and not carbonated water are reacted.This preparation method can produce the following fine powder of 0.1 or 0.1 μ m, but owing to its high cost, is not used basically now.
In addition, after can also enumerating alkali such as adding NaOH in the magnesium salt solution that in seawater and bittern, contains, by effects such as pressurizeing, heat crystallization is not grown, clean, filter the sedimentary method of colloidal (hereinafter, in this way produce be called noncrystalline growing magnesium hydroxide).
Though this noncrystalline growing magnesium hydroxide price is the cheapest, be used in the resin, because the aggegation effect of hydroxyl, make it become harder, moment of torsion uprises, thus with the difficulty of mixing of resin, in addition, can not use owing to generated the extremely low composition of elongation rate of tensile failure.At present, be specifically designed to draining neutralization, stack desulfurization.
About magnesium hydroxide or magnesium hydroxide and organosilicon and usefulness,, following enumerating report is arranged in the document at present as non-bittern type flame-retarded resin compositions.
Use surface-treated magnesium hydroxide (with reference to patent documentation 1～3).In resin, allocate magnesium hydroxide and organopolysiloxane (with reference to patent documentation 4～6) into.In addition, researchist of the present invention is to thermoplastic resin, magnesium hydroxide, high-polymerization degree dimethyl organopolysiloxane and contain in the mixture of oily organopolysiloxane of vinyl, cooperate under the occasion of noble metal catalyst, demonstrate higher flame retardant resistance (with reference to patent documentation 7).
