Description
Technical field
The invention belongs to enhance the technical field of PBT fiber, and in particular to a kind of production system of fiber glass reinforced PBT fiber
System.
Background technique
Polybutylene terephthalate (PBT) is excellent thermoplastic material, has extraordinary chemical stability, machinery strong
Degree, electrical insulation characteristics and thermal stability, but PBT moisture-absorption characteristics is very weak, and tensile strength is general, only 50MPa, and the crystallization of PBT is very
Rapidly, this, which will lead to, causes bending deformation because inhomogeneous cooling is even.
Summary of the invention
Goal of the invention: purpose of the invention is to overcome the shortcomings in the prior art, provides a kind of whole tensile strength
Significantly increase, product warpage properties be improved significantly fiber glass reinforced PBT material production system.
Technical solution: in order to solve the above-mentioned technical problem, a kind of production system of fiber glass reinforced PBT material of the present invention
System, it successively includes glass/PBT fiber blend device, screw extrusion device, cooling device, traction device and pellet device, institute
Stating screw extrusion device includes five sections of heating zones, respectively the first heating zone, the second heating zone, third heating zone, the 4th heating
Area and the 5th heating zone are equipped with filler adding set at the 4th heating zone of the screw extrusion device.
The glass/PBT fiber blend device is high-speed mixer.
The screw extrusion device is integrated partition heating formula screw rod melting plant.
The filler adding set is adjoining dimensions filler adding set in length and breadth.
The utility model has the advantages that compared with prior art, the present invention its remarkable advantage is: overall structure setting of the present invention rationally, is adopted
With glass/PBT fiber blend device, glass fiber reinforcement is added, significantly increases whole tensile strength, up to 170MPa, adopts
With adjoining dimensions filler adding set in length and breadth, the filler of adjoining dimensions in length and breadth is added in mixture, is made whole in process
Vertical direction tensile strength is obviously improved, and the warpage properties of product are improved very well, this, which is more advantageous to, prepares all kinds of accurate products,
Products obtained therefrom performance is good, moderate, long service life.
Detailed description of the invention
Fig. 1 is integrated connection schematic diagram of the invention；
Fig. 2 is the connection schematic diagram of heretofore described screw extrusion device Yu filler adding set.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, the production system of a kind of fiber glass reinforced PBT material of the present invention, it successively includes glass
Fibre/PBT fiber blend device 1, screw extrusion device 2, cooling device 3, traction device 4 and pellet device 5, the screw extruding
Device 2 includes five sections of heating zones, respectively the first heating zone 6, the second heating zone 7, third heating zone 8, the 4th heating zone 9 and the
Five heating zones 10 are equipped with filler adding set 11 at the 4th heating zone 9 of the screw extrusion device 2；Glass/the PBT
Fiber blend device 1 is high-speed mixer；The screw extrusion device 2 is integrated partition heating formula screw rod melting plant；Institute
Filler adding set 11 is stated as adjoining dimensions filler adding set in length and breadth.Overall structure of the present invention setting rationally, using glass/
PBT fiber blend device is added glass fiber reinforcement, significantly increases whole tensile strength, up to 170MPa, using ruler in length and breadth
Very little close filler adding set, adds the filler of adjoining dimensions in length and breadth in mixture, makes the whole vertical direction in process
Tensile strength is obviously improved, and the warpage properties of product are improved very well, this, which is more advantageous to, prepares all kinds of accurate products, products obtained therefrom
Performance is good, moderate, long service life.
The present invention provides a kind of thinking and methods, and there are many method and the approach for implementing the technical solution, the above institute
Stating is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, is not being departed from
Under the premise of the principle of the invention, several improvements and modifications can also be made, these improvements and modifications also should be regarded as guarantor of the invention
Range is protected, all undefined components in this embodiment can be implemented in the prior art.
