Description
Technical field
The present invention relates to a kind of nylon resin materials, particularly relate to a kind of nylon resin with good flame-retardance energy, anti-deformation nature and high GWIT, CTI.
Background technology
Nylon (i.e. polymeric amide) density of material is little, good processability, wear resistance and self lubricity are good, Heat stability is good, good corrosion resistance, rebound resilience are high, there is excellent electrical property and higher rigidity, and finished product is without the need to rotproofing, used in every field by the engineering materials as a kind of alternative non-ferrous metal.
Although have a series of excellent performance, but nylon flame retardant properties is poor, and produce drippage in combustion, in use do not belong to fire safety evaluating material, also can initiation fire, the fire protection requirement of the unserviced industrial electric such as especially electric and household electrical appliances more and more by human consumer and manufacturer pay attention to, therefore, current academia is become to nylon flame-retardant modified and industry member is paid close attention to and the problem of tackling key problems jointly.
CN103772971A discloses a kind of fire-retardant nylon material that can be used for switch, and comprise nylon resin, polyimide, silicate, stearate and mineral filler auxiliary agent, flame retardant properties reaches 1.6mm, fusing point 280-290 DEG C, and tensile strength is 60-70MPa.
CN103756308A discloses and a kind ofly can be used for various switch flame-proof abrasion-resistant nylon composite materials pulling out mouth and preparation method thereof, comprise the components such as nylon resin, tetrafluoroethylene, carbon fiber, Graphite Powder 99, magnesium hydroxide crystal whisker and zinc oxide, heat-drawn wire (1.8MPa) can reach 260 DEG C, there is good mechanical property, and flame retardant rating is V1.
CN103756306A discloses a kind of environmental-protection fire-resistant nylon, comprises nylon resin, acrylic resin, trifluoroacetic acid, oyster shell whiting etc., can realize the effect of low cigarette.
Glass fibre reinforced nylon is modified nylon mode conventional at present, good mechanical property, dimensional stability, thermotolerance, anti-fatigue performance etc. can be obtained, but report, be that glass fibre reinforced nylon excellence easily occurs " candle wick effect " in combustion, make material more inflammable.For this reason, CN103709743A discloses a kind of enhancing fire-retardant nylon, comprises nylon resin, glass fibre, fire retardant, oxidation inhibitor, coupling agent etc., utilizes twin screw extruder melt blending system, fire-retardant rank reaches UL94-Vo level, can be used for the fields such as electronic apparatus.
This area is thought, flame retardant properties is promoted to 1.6mm by 3.2mm, is promoted to 0.8mm, is promoted to 0.4mm, and wherein often promote a grade, security can improve more than 5 times, and 0.4V0 is the security of 20 times of 3.2Vo; GWIT often promotes 25 DEG C by 700 DEG C, and security can promote more than 1 times, until 900 DEG C can have more security, security is 8 times of 700 DEG C, current above-mentioned safety grades does not all generally reach, but countries in the world have started successively to formulate new flame-retardant standard, and enforces.
In addition, for thin-walled and baroque parts, to need the air switch combining assembling, one side is bright and clean plane attractive in appearance, and reverse side is complicated structure, and the warpage of the finished pieces with complex shapes such as straight line muscle wherein, geometry muscle, post is uncontrollable, have a strong impact on follow-up assembling, even if assemble by force, because the existence of buckling force is easy to the disengaging causing device component in transportation and use procedure, there is serious potential safety hazard.
