Description
Background technology
The present invention relates to polymeric material field, specifically, relate to a kind of high temperature resistant halogen-free flame-retardant daiamid composition.
Background technology
Polymeric amide (PA is commonly called as nylon) is a kind of engineering plastics that in five large-engineering plastics, consumption is maximum, kind maximum, qualification is the oldest, and output occupies first of five large general engineering plastic.Engineering plastics polymeric amide has good over-all properties, intensity, higher than metal, has good mechanical property, thermotolerance, wearability, chemical resistant properties, flame retardant resistance and self lubricity, and easily processes, frictional coefficient is low, so be widely used in electrical-electronic field.Because the flame retardant properties of polymeric amide itself generally can only reach UL94V-2 level, so the polymeric amide being applied to electric field needs to improve its flame retardant properties through modification.
At present, in order to make nylon material possess certain flame retardant resistance, thus usually halogen containing flame-retardant is added, thus cause producing a large amount of toxic smog during burning, fact proved, in fire failure, what cause the massive loss of life is not big fire itself, but toxic smog makes to be choked to death by the personnel of besieging.Therefore, the environmental protection class material of halogen-free flameproof is future developing trend.
Through retrieval, Chinese patent ZL 200710074664.2, polyamide resin of a kind of halogen-free phosphor-free environmental protection inflaming retarding of denomination of invention and preparation method thereof, this polyamide resin has the preparation of raw material of following proportioning to form, polyamide 68 one 92%; Melamine cyanurate 5 one 25%; Toughner 2 one 15%; Oxidation inhibitor 0.1 one 1%; Thermo-stabilizer 0.1-2%; Crystallization promoter 0.1-2%; Described toughner is thermoplastic elastomer; Described thermo-stabilizer is the oxidation inhibitor of a class copper composition and the mixture of synergistic agent; Described crystallization promoter is the careful powdered mixture of a kind of organic composition and inorganic components.Although the polyamide resin in this patent achieves halogen-free phosphorus-free inflaming retarding, the resistance to elevated temperatures of this product does not have digital proof, and resistance to elevated temperatures is also uncertain.
