Abstract

The invention discloses a thermoplastic composite product.The product is characterized by being obtained by processing carbon fiber, thermoplastic plastic and additive through injection molding, and the length of 50% or above of carbon fiber in the processed product is larger than or equal to 5 mm.The product has the advantages that the length of most (50% or above) of carbon fiber in the processed product is 5 mm to 30 mm, so the processed product is good in impact resistance and can be used as a functional structural piece such as an automobile hub, a bumper, a reinforcing beam and a supporting frame; the product is obtained by online mixing injection molding of an injection molding machine, a connecting pipeline of a twin-screw extruder and the injection molding machine is in a closed state during processing, the temperature and pressure of polymer are controllable in the whole process, and the product is stable in quality, can be processed into a product of a complex structure, and is precise in size, free of post-processing and high in production efficiency; in addition, through the combination of the injection molding process technology during processing, the more precise thermoplastic composite product is obtained through processing.

Description

A kind of thermoplastic composite product
Technical field
The present invention relates to the product obtained by composite processing, particularly relate to a kind of good thermoplastic composite product of shock resistance.
Background technology
Carbon fibre composite is widely used in multiple field because of good material behaviors such as it are lightweight, intensity is good.At present, the processing and forming technology of carbon fibre composite mainly has: hand pasting forming, Wrapping formed, resin transfer molding and pellet injection mo(u)lding, wherein: hand pasting forming and Wrapping formed have that production efficiency is low, labor intensity is big, product quality is wayward, and employing thermoset resin material, the shortcoming such as cannot recycle, mainly for the production of the parts of simple shape in auto parts, it is difficult to meet the requirement of auto industry production and environmental protection；Resin transfer molding technique be mainly characterized in that closed mould operations, pollution-free, briquetting pressure is low, reinforcing material can by designing requirement laying, goods two sides is bright and clean and can make complex-shaped massive article etc., but resin transfer molding technique adopts thermoset resin material, cannot recycle, it is difficult to meet the requirement of auto industry production and environmental protection；And pellet injection mo(u)lding is that carbon fibre composite is first processed into diameter is about 3mm, length is about the long pellet of 15mm, then longer pellet is added injection mo(u)lding in conventional injection molding machine, what it adopted is thermoplastic composite, compared with front several moulding processs, production efficiency is high, the product recoverable that processing obtains, impact resistance is significantly improved, but or cannot be used for manufacturing the parts that stress is stronger, as manufactured the functional structure parts such as the wheel hub of automobile, bumper, buttress brace and bracing frame.
Summary of the invention
The technical problem to be solved is to provide a kind of intensity height, shock resistance better, can be used as the thermoplastic composite product of the functional structure part such as automotive hub, bumper.
This invention address that the technical scheme that above-mentioned technical problem adopts is: a kind of thermoplastic composite product, obtained by injection mo(u)lding processing by carbon fiber, thermoplastic and additive, and in the product that obtains of processing the length of the carbon fiber of more than 50% be more than or equal to 5mm.
In the product that processing obtains, the length of the carbon fiber of more than 70% is be more than or equal to 5mm.
All length accounts for 50%～95% be more than or equal to the carbon fiber that length in the carbon fiber of 5mm is 5～30mm.
Described thermoplastic is polyethylene, polypropylene, polrvinyl chloride, polystyrene, polyformaldehyde, poly-carbonic acid cheese, polyamide, acrylics, polyolefin and copolymer thereof, poly-mock, polyphenylene oxide, at least one in chlorinated polyether, it is also possible to for other type of thermoplastic and combination thereof.
Described carbon fiber is the polymer mixed by continuous print carbon fiber rove adds the double screw extruder thermoplastic with fritting and additive, and by double screw extruder, carbon fiber rove is carried out rough cutting while mixing, then the mixture exported from double screw extruder is expelled in the process being shaped in mould through the injection cylinder of injection machine, injection flow passage and mold runner obtains after the carbon fiber after rough cutting being sheared further.
Compared with prior art, it is an advantage of the invention that due in thermoplastic composite product carbon fiber length major part (more than 50%) all at 5～30mm, make to process the product shock resistance obtained better, can be used as automotive hub, bumper, the functional structure part such as buttress brace and bracing frame, and this product is by the online mixing injection mo(u)lding of injection machine, in the process of processing, the duct coupling of double screw extruder and injection machine is in closure state, the temperature and pressure whole process making polymer is controlled, constant product quality, and the product with labyrinth can be processed, product size is accurate, without post-treatment, production efficiency is high；Additionally, may also be combined with Shooting Technique technology in the course of processing, process more accurate thermoplastic composite product.
Accompanying drawing explanation
Fig. 1 is the machining sketch chart of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
A kind of thermoplastic composite product, by carbon fiber, thermoplastic and additive are obtained by injection mo(u)lding processing, in the product that processing obtains, the length of the carbon fiber of more than 50% is 5mm, and all length accounts for 50%～95% be more than or equal to the carbon fiber that length in the carbon fiber of 5mm is 5～30mm, carbon fiber is the polymer mixed by continuous print carbon fiber rove 3 adds the double screw extruder 2 thermoplastic with fritting and additive, and by double screw extruder 2, carbon fiber rove 3 is carried out rough cutting while mixing, then the mixture exported from double screw extruder 2 is expelled in mould 5 in the process being shaped through the injection cylinder 4 of injection machine, obtain after the carbon fiber after rough cutting being sheared further by injection flow passage and mold runner.
In above-described embodiment, thermoplastic is polyethylene, polypropylene, polrvinyl chloride, polystyrene, polyformaldehyde, poly-carbonic acid cheese, polyamide, acrylics, polyolefin and copolymer thereof, poly-mock, polyphenylene oxide, at least one in chlorinated polyether, it is also possible to for other type of thermoplastic and combination thereof；Additive is additive conventional in conventional injection molding, as: antioxidant, compatilizer etc..
