Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
A kind of high-termal conductivity polyether-ether-ketone composite material, is made up of the raw material of following parts by weight：60~75 parts of polyether-ether-ketone,
5~10 parts of carborundum, 5~10 parts of boron nitride, 10~20 parts of basalt fibre, 0.5~1 part of antioxidant.The polyether-ether-ketone, carbon

, the preparation for follow-up high-termal conductivity polyether-ether-ketone composite material provides basis.The basalt fibre is 8~10mm short fibre
Dimension, raw material mixing is not only improved, and can functions well as bridge joint effect, is advantageous to the formation of heat conduction network, improves polyether-ether-ketone
The heat conductivility of composite.The density of polyether-ether-ketone is 1.30g/cm3, the conventional antioxidant of antioxidant selection.
A kind of preparation method of high-termal conductivity polyether-ether-ketone composite material, comprises the following steps：
(1) dry：The raw material of the high-termal conductivity polyether-ether-ketone composite material described in claim 1 is provided, respectively by polyethers
Ether ketone, carborundum, boron nitride, basalt fibre dry 5-6h at a temperature of 180~190 DEG C, moisture content is less than 40ppm；
(2) mix：Dried ether ether ketone, carborundum, boron nitride, basalt fibre and antioxidant are added mixed at a high speed
Control high-speed mixer rotating speed to mix 20~30min for 900~1000r/min in conjunction machine to be well mixed.
(3) melt molding：Mixed raw material is put into mould, is forced into 10~20min of pressurize after 2~3MPa, then
3~4h of heat-insulation pressure keeping at a temperature of being heated to 380-400 DEG C, then pressure release are stripped after being cooled to 80~90 DEG C, the shaping after the demoulding
Material is again heated to 270~280 DEG C of 2~3h of insulation, produces high-termal conductivity polyether-ether-ketone composite material.
Carborundum, boron nitride, basalt fibre can be played synergy by the present invention as heat filling, be significantly improved
PEEK heat conductivility.In order to study influence of the basalt fibre content to PEEK composite pyroconductivities, polyethers is chosen
Ether ketone 70g, carborundum 10g, boron nitride 5g, antioxidant 1g, then be separately added into basalt fibre 0g, 3g, 5g, 10g, 15g, 20g,
25g, 30g, 35g, 40g, 45g are prepared into PEEK composites, testing thermal conductivity, as a result as shown in Figure 1, it can be seen that：With
The increase of basalt fibre dosage, the pyroconductivity of the composite is in rising trend, when basalt fibre dosage be 10~
During 20g, pyroconductivity rising is relatively stable and maximum, up to 0.9W/m DEG C, and as basalt fibre dosage further increases
Add, and during more than 20g, pyroconductivity declines then and progressively.Found by studying, this is due to that basalt fibre dosage is relatively low
When, basalt fibre and carborundum, boron nitride particles are each wrapped up by PEEK resins, and contact is seldom to each other so that composite wood
Expect that pyroconductivity is low；With the increase of basalt fibre dosage, basalt fibre and carborundum, boron nitride particles are by PEEK resins
The degree of parcel reduces, and system is internally formed the ability enhancing of thermal conducting path so that and composite pyroconductivity increases, but when profound
After military rock fiber consumption is more than 20g, disorderly and unsystematic, can not to be formed on direction of heat flow effective chain is disperseed in intrinsic silicon,
The increase of thermal conductivity factor is limited, so making the pyroconductivity of its composite have progressively downward trend.Therefore, height of the present invention is led
Basalt fibre dosage can play its optimal excellent properties, fully at 10~20 parts in hot polyether-ether-ketone composite material
Bridge joint effect is played, and carborundum and boron nitride particles isolated and that thermal conductivity is high are connected, significantly improves height
The pyroconductivity of thermal conductivity polyether-ether-ketone composite material.
