Description
Technical field
The present invention relates to technical field of polymer materials, it is specifically a kind of can laser engraving fire-retardant nylon PA66 materials and its
Preparation method.
Background technology
PA66 materials have excellent wearability, self lubricity, mechanical strength is higher, be widely used in manufacture machinery, automobile,
The part of chemistry and electric device.But PA66 the shortcomings that there is itself, impact strength is high when such as low temperature, poor toughness, molding
Shrinking percentage is big, of high cost, water absorption rate is big etc., and therefore, non-modified PA66 is for that need to extend to it when the fields such as machinery, electronics
Property, notch impact strength and low-temperature flexibility etc. are modified.Traditional method of modifying mainly using polyolefin (PE, PP,
EPDM, POE etc.) maleic anhydride grafting is carried out, blending extrusion, modified polyolefin and PA66 compatibilities are then carried out with PA66
It improves, performance has obtained apparent improvement.But the method for modifying complex process, of high cost, long flow path, there is chemical contamination, and
And the monomer or monomer homopolymers for inevitably having unreacted to be grafted remain in modified material, influence its performance.If PA66 materials
For electronic enterprises, need to improve its flame retardant property, it is more at present to use a large amount of common halogen antimony fire retardants of addition,
Although in the anti-flammability for improving material to a certain degree, the mechanical property and electrical insulation capability of material are all by very big shadow
It rings, directly affects application of the material in electronic enterprises.And with the raising of environmental requirement, traditional bromide fire retardant is
Through the requirement that cannot meet European Union's ROHS and WEEE instruction.

The inorganic combustion inhibitors such as aluminium hydroxide, expansile graphite are used in compounding, using matrix resin as the dark red colored particle of carrier, safety problem
It is resolved.Its low cigarette, flame retarding efficiency are high；Without dust pollution, processing performance are excellent；Low-density, thermal stability be good, product object
Rationality can decline few；It is non-blooming in process, do not migrate, do not corrode mold, especially product there is high resistance to tracking to refer to
Number, in electronic apparatus using upper with the obvious advantage, the antioxidant is to select 1,098 two kinds of irgasfos 168 and antioxidant by weight
For 1: 1 mixture, the lubricant is stearate, ethylene bis-fatty acid amides TAF or CaO, and the heat stabilizer is calcium
Zinc heat stabilizer, the coupling agent are KH-560.
It is described can laser engraving fire-retardant nylon PA66 materials preparation method, steps are as follows：
1) each component is weighed by the weight proportion；
2) by the mixing of the PA66 resins, fire retardant, antioxidant, lubricant, heat stabilizer, coupling agent and laser carving powder that claim
Material, it is that 4~6min is mixed in 400~500r/min batch mixers that rotating speed, which is added, obtains premix；
3) premix that step (2) obtains and glass fibre are fed into double screw extruder, then barrel temperature is:
250~260 DEG C of back segment, 240~250 DEG C of stage casing, 230~240 DEG C of leading portion, screw slenderness ratio 30~35, screw speed 300~
600r/min, by heating melting, squeeze out tie rod, cooling, drying, granulation obtains can laser engraving fire-retardant nylon PA66 pellets.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention selects red phosphor masterbatch as fire retardant, low cigarette,
Flame retarding efficiency is high；Without dust pollution, processing performance are excellent；Low-density, thermal stability are good, product physical property declines less；Processing
It is non-blooming in the process, do not migrate, do not corrode mold, especially product there is the high index of resistance to tracking, in electronic apparatus application
Upper with the obvious advantage, by adding laser carving powder in the feed, the addition of laser carving powder can make in plastic surface laser mark/stamp
More smoothly, the clarity of plastic material laser-marking is substantially increased, can directly be mixed with existing toner and formula makes
With, do not have a great impact to the performance of material, lower additive amount makes use cost reduce, and be suitable for inhomogeneity
The Laser Jet device of type.
