The product disclosed by the invention has the advantages of excellent mechanical property and good stability and achieves a good flame-retardant effect by being compounded by simultaneously adopting the ammonium polyphosphate and the trioctyl phosphate; and according to the invention, two fire retardants are both halogen-free fire retardants, so that the safety and the environment friendliness are achieved.
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of fire retardant PBT with no halogen/ASA alloy.
Background technology
PBT is one of the most tough and tensile engineering thermoplastic materials, and it is those semi-crystalline materials, and extraordinary chemical stability, physical strength, electrical insulation characteristics and thermostability are arranged, and water absorbability is very weak.But the notched Izod impact strength of PBT is low, and molding shrinkage is large, is difficult to satisfy people's demand.
ASA is the acrylonitrile-acrylate-styrene terpolymer, is the engineering plastics of developing for the poor shortcoming of ABS weathering resistance.It has splendid weathering resistance, even be exposed to for a long time outdoor ultraviolet ray, humidity, drench with rain, under illumination and the ozone condition, also can keep physical property stable without application.Being particularly suitable for not application directly uses out of doors.Be widely used in the fields such as automobile, electric, daily necessities, outdoor decoration material.If PBT and ASA are made blend alloy, toughness, weathering resistance, the stability of the existing ASA of prepared alloy have again the thermotolerance of PBT.
At present, the fire retardant that adopts in the most fire retardant material is halogenated flame retardant, the halogenated flame retardant good flame retardation effect, addition is few, performance impact to material is less, but the amount of being fuming is large, and the hydrogen halide that discharges has corrodibility, and can produce poisonous many bromos of carcinogenic substance benzo and dislike English and PBDF, affect the human homergy.European Union comes into effect the RoHS instruction on July 1st, 2006, strictly limits the use of polybromodiphenyl ether PBDE, Polybrominated biphenyl PBB.
Therefore, how to overcome the deficiencies in the prior art, producing is that a kind of fire retardant PBT with no halogen/ASA alloy is the problem that polymeric material field is needed solution badly.
Summary of the invention
The objective of the invention is provides a kind of fire retardant PBT with no halogen/ASA alloy in order to solve the deficiencies in the prior art, and this invention product not only has excellent mechanical property, also has preferably flame retardant properties.
The technical solution used in the present invention is as follows:
A kind of fire retardant PBT with no halogen/ASA alloy is characterized in that comprising the following raw material according to the parts by weight meter: 100 ~ 120 parts of PBT resins, 20 ~ 50 parts of acrylonitrile-styrene-acrylic ester graft copolymers, 6 ~ 9 parts on carbon fiber, 0.5 ~ 2 part of nano zine oxide, 0.5 ~ 2 part of antioxidant 1010,160 0.5 ~ 2 parts in oxidation inhibitor, 9 ~ 12 parts of ammonium polyphosphates, 4 ~ 6 parts of trioctyl phosphates, 0.5 ~ 2 part of thermo-stabilizer, maleic anhydride grafted ethene-1 ~ 3 part of 1-octene copolymer, 0.5 ~ 2 part of lubricant.
Further its prioritization scheme is that described thermo-stabilizer is dimethyl dimercapto 2-ethyl hexyl ethanoate tin.
Further its prioritization scheme is that described lubricant is glyceryl monostearate.
Preparation method of the present invention may further comprise the steps:
The raw material that weighs up is mixed 10min in homogenizer, then deliver to the twin screw extruder melting, mixing, extrude, each section extruder temperature is 200-240 ℃, again through cooling, pelletizing, drying, at last the packing, namely get product of the present invention.
The present invention compared with prior art, its beneficial effect is:(1) product mechanical property of the present invention is excellent, good stability; (2) the present invention adopts ammonium polyphosphate and trioctyl phosphate composite, reaches good flame retardant effect, and two kinds of fire retardants all are halogen-free flame retardants, safety, environmental protection; (3) added nano zine oxide, not only improved the stability of product of the present invention, also so that product of the present invention has certain antimicrbial power.
