Beneficial effects of the present invention are：
1st, on the one hand, the present invention is main strengthens PC/ABS alloys using basalt fibre, and PC/ABS alloys are thermoplasticity
Material, relative to traditional fiber reinforcement thermosetting material, the recyclable recycling of thermoplastic, and technological requirement is low, can stop
The product after type is made into, chemical-resistance is good；Basalt fibre is a kind of high-strength, Gao Mo inorganic mineral fiber, and resistance to height
Temperature, it is corrosion-resistant to wait excellent performance, it is a kind of ideal material of green non-pollution, also, basalt fibre tensile strength is protruded, and it is profound
Military rock fiber to significantly increase the tensile strength of PC/ABS alloys, the composite bending strength of preparation is high, tensile strength is high,

Effect is good.The third aspect, after tested, composite good flame retardation effect of the invention, safety and environmental protection, heat endurance are good, acidproof, resistance to
Alkali, stable chemical nature.
2nd, basalt fibre is the continuous fiber that draw ratio is 1500, in composite of the invention, using continuous fibre
Dimension so that the minimum yardstick that retains of basalt fibre is larger, is uniformly dispersed, and in composite inner, continuous basalt fiber
The three-dimensional net structure that fiber winds mutually can be formed so that fiber reinforcement effect is more obvious, further be conducive to improving multiple
The intensity of condensation material.In addition, the stress concentration point of fiber end is also crackle initiation point, stress cracking is easily caused, so as to make
Decline into toughness.Because the minimum reservation length of fiber in continuous fiber composite material sample is more long, end quantity then can be notable
Reduce, so as to maintain preferable impact property.
3rd, coupling agent is epoxy resin E51 and alicyclic epoxy compounds the KH-550 that starching is obtained, due to basalt fibre
Modulus is higher, and PC/ABS resins bear load, such as basalt fibre as an entirety after basalt fibre is bonded together
Interfacial adhesion strength with PC/ABS resins is not high, then the intensity enhancing of composite is not obvious, therefore, added in the present invention
Coupling agent, the adhesive strength between basalt fibre and PC/ABS resins is improved by coupling agent, is conducive to improving composite
Overall tensile strength.The KH-550 that coupling agent is obtained from epoxy resin E51 and alicyclic epoxy compounding starching in the present invention,
Group after KH-550 hydrolysis can be with the hydroxyl stable bond of production after basalt fibre water absorbent surface, also can be with PC/ABS
Resin-bonded, so as to effectively improve the interface binding power of basalt fibre and PC/ABS resins, is further conducive to improving compound
The bending strength of material, tensile strength and impact strength.
4th, PC/ABS resins are defined tough matrix, and impact fracture behavior is triggered based on shear yielding with crazing high
Energy and low crazing propagation energy, therefore with unnotched impact strength and relatively low notch impact strength higher.Therefore, PC/
The toughness reinforcing of ABS resin is mainly based on shear band initiation.Now, it is necessary to the small particle toughener of shear band can be triggered
Modified PC/ABS resins, when by external force, to trigger the shear band of intrinsic silicon, with energy absorption, prevent matrix from destroying.
Meanwhile, the toughener of slightly larger particle diameter is added, the micro-crack produced because of being hit can be prevented, energy absorption improves body
Face impact strength.Core-shell polymers in the present invention from styrene, acrylonitrile-butadiene rubber are toughener, and glue contains
It is 55-70% to measure, and the particle diameter of the toughener is larger, can be effectively improved the impact strength of PC/ABS resins, is further conducive to carrying
The bending strength of composite high, tensile strength and impact strength.
5th, lubricant is stearmide series lubricant agent, and the addition of lubricant plays lubrication to whole composite macromolecular
Effect, reduces the coefficient of friction of product and the external world, and stearmide series lubricant agent is good with other components compatibility of the invention, and profit
Slip can be good, is conducive to increasing mechanical strength of the invention.
6th, due to containing polybutadiene in ABS resin, it is oxidized easily, the addition of antioxidant, it is to avoid ABS in composite
Resin is excessively oxidated decomposition, is conducive to improving the stability of composite.
7th, compatilizer is the copolymer of styrene and maleic anhydride, and compatilizer can react with the polar group in ABS, is improved
The adhesive strength of ABS and basalt fibre, is further conducive to improving the bending strength of composite, tensile strength and impact by force
Degree.
8th, fire retardant be TDE such as 4010, brominated epoxy such as CXB-714C and aggretion type fire retardant FR-
The mixture of one or more in Emerald1000；The fire retarding synergist is antimony oxide, inorganic particle and superelevation point
The compound of son amount polysiloxanes composition, the weight percentage of antimony oxide is 20-80% in the compound.On the one hand,
Fire retardant effect selected by the present invention is good, high temperature resistant, can improve heat endurance of the invention, meanwhile, polymer can be increased
Intermolecular force and rigidity, reduce its entropy of melting in addition.Second aspect, fire retardant and fire retarding synergist are engaged, and realize solidifying
The fire-retardant gentle mutually fire-retardant dual synergistic fire retardant mechanism of rephasing reaches the fire-retardant purpose of synergistic, further increases of the invention fire-retardant
Effect.
9th, based on the enhanced PC/ABS composites of basalt fibre, including following parts by weight component, 50 parts of PC；
20 parts of ABS；14 parts of basalt fibre；4 parts of toughener；1.3 parts of lubricant；0.5 part of coupling agent；3 parts of compatilizer；Fire retardant 6
Part；1 part of fire retarding synergist；0.2 part of antioxidant.Load is born mainly by basalt fibre due to composite, if basalt
Content is relatively low, then occur larger overlapping between fiber, and enhancing effect is poor, if basalt content is high, each component can be caused to mix
Uneven, it is poor that PC/ABS cannot be completely soaked compatibility between parcel basalt fibre, each component, is only formulated from this, profound
The content of military rock fiber is 20% or so, the composite of preparation, and the addition of each component is most suitable amount, basalt fibre
Can be in the presence of coupling agent, compatilizer, toughener, lubricant, basalt fibre can combine closely with PC/ABS, and the Black Warrior
Rock fiber uniform and stable can be distributed in PC/ABS surfaces, so as to improve the intensity of composite to greatest extent.
10th, in the composite preparation process, when extrusion temperature is too low, macromolecular material shows as rigid solid shape
State, it is impossible to exist with molten condition, it is difficult to extrusion molding is carried out, if temperature is too high, during more than 220 DEG C, more than ABS resin
Decomposition temperature, ABS resin is aging serious, is unfavorable for improving the overall intensity of composite.When temperature is 220 DEG C, now ABS
The free movement enhancing of strand in resin, resin viscosity reduces, the package action reduction to basalt fibre, by external force field
Shearing and stretching after, basalt fibre can produce certain miniature deformation, and basalt fibre average fiber length is elongated, enhancing
Effect more preferably, is further conducive to improving bending strength, tensile strength and the impact strength of composite.Screw speed is
160r/m-180r/m, if rotating speed is excessive, can cause shearing force suffered by composite big, and basalt fibre is twisted disconnected, average fiber
Length reduces, tensile strength reduction, if rotating speed is too small, each component in composite can be caused uniformly to mix, and causes
The material strip for arriving is uneven, when rotating speed is 170r/m, the composite tensile strength highest for obtaining.
