The invention discloses a kind of long glass fiber reinforced polyamide compoiste materials, belong to field of compound material, improve the appearance of composite material, and improve the heat conductivility of composite material.The present invention is divided into including each group in mass ratio：Polyamide is 40% 60%, and low molecular polyamides are 5% 10%, and glass fibre is 20% 40%, and thermal conducting agent is 2% 10%, and lubricant is 0.5% 2%.
Description
Technical field
The invention belongs to field of compound material more particularly to a kind of long glass fiber reinforced polyamide compoiste materials.
Background technology
Glass fibre reinforced composite material, be using polymer as matrix, using glass fibre as reinforcing material manufactured composite wood
Material, combines the performance of polymer and glass fibre.Glass fibre reinforced composite material is classified by the length of fiber, can be divided into long fibre
Composite material and short fiber composite material；Glass fibre can be divided into alkali-free aluminoborosilicate (abbreviation alkali-free fibre according to chemical constituent
Dimension) and have alkali without borosilicate (alkali fiber in abbreviation).
Fiberglass reinforced plastics are the main method and means of current modifying plastics, can be by the performance of general-purpose plastics significantly
It improves, reaches the performance level of engineering plastics, so fiberglass reinforced plastics technology is widely used.
The mainstream technology of domestic production fiberglass reinforced thermoplastic is by continuous glass-fiber yarn in the suitable of extruder at present
When position enters the barrel of extruder, the screw rod being engaged in barrel is stirred disconnected and is obtained when rotating.For polyamide (PA) class
The production of the fiberglass reinforced plastics of plastics, PA resins also need to be dried before entering extruder, to remove the water in resin
Point, prevent the quality for occurring to hydrolyze and influence fiber glass reinforced polyamide composite material in the extruder of high temperature.
Fiber glass reinforced polyamide composite material in fiberglass reinforced plastics has excellent mechanical property and dimensional stability,
But fiber glass reinforced polyamide composite material glass in injection moulding easily floats on the surface of product, has come not to the appearance of product
Profit influences, and to influence its application in the more demanding place of appearance, and due to not paying close attention to thermal conductivity of material, limits
Its application in related field.
Invention content
The present invention provides a kind of long glass fiber reinforced polyamide compoiste materials, improve the appearance of composite material, and improve
The heat conductivility of composite material.
In order to achieve the above object, the present invention uses following technical scheme：
A kind of long glass fiber reinforced polyamide compoiste material, in mass ratio each group are divided into：
Polyamide 40%-60%
Low molecular polyamides 5%-10%
Glass fibre 20%-40%
Thermal conducting agent 2%-10%
Lubricant 0.5%-2%.
In component described above, the polyamide is nylon 46, and the glass fibre is for alkali-free or without the length of lay
Glass fibre, the thermal conducting agent is 85%-100% heat conduction powder particle by mass fraction and mass fraction is 0%-15% long
Diameter is than the whisker composition for 50-100；The wherein described conductive powder end particle is selected from high heat conduction aluminum nitride powder, grain size 4um-15um；
The whisker is selected from one or both of silicon carbide whisker or aluminium nitride whisker.
Beneficial effects of the present invention are：The present invention provides a kind of long glass fiber reinforced polyamide compoiste material, increases in roving glass fiber
It is added low molecular polyamides and lubricant in strong polyamide compoiste material, low molecular polyamides mobility in process
It is good, because shear action can float to the surface of material during material flow, to assign material good gloss, in addition, making
There is the lubricant for improving material finish, can not only prevent the adherency of raw material melt and equipment, and due to
There is unique chondritic, that there are material surfaces is macro for this chondritic when the dendritic molecule of the lubricant flocks together
Sight upper surface is any surface finish；Meanwhile under the collective effect of toughener and glass fibre, also glass fibre reinforced composite material being made to have
There is the characteristics of high intensity, and thermal conducting agent is added in the composite, improve the heat conductivility of material, expands roving glass fiber increasing
The use scope of strong polyamide compoiste material.
